- set aside a minute every now and then to close your eyes to re-moisten your eyeballs to avoid drying, itching, redness

- set aside a few minutes to stare and focus your sight on one object at a far distance. this eases up your eye muscles used for near sight, and allows you to use your far sight muscles

I thought I knew how to put eye drops in. Tilt head back, squeeze bottle, drop goes in eye. Simple. Then I watched about 30 patients do it during my aunt's follow-up visits at Shroff Eye Centre and realised almost everyone does it wrong. Including me.

The doctors and staff there spent a surprising amount of time correcting patients' technique. Not because they were being fussy. Because wrong technique means the medicine isn't reaching where it needs to go. You're wasting drops and wondering why they're not working.

Here's what most people get wrong and how to actually do it right.

Mistake 1 — Dropping it directly onto your eyeball

This is what almost everyone does. Tilt head, aim for the centre of the eye, squeeze. The drop hits your cornea directly and your first reflex is to blink hard. That blink pushes most of the drop out before it can absorb.

The correct way is to pull your lower eyelid down gently with one finger creating a small pocket between the lid and your eye. Drop the medicine into that pocket, not directly onto your eyeball. Then close your eye gently. Don't squeeze it shut, don't blink rapidly. Just close softly and let the drop spread naturally.

During my aunt's recovery at Shroff the doctor demonstrated this exact technique on the first follow-up visit because my aunt had been dropping directly onto her eye for three days and complaining that the drops weren't helping. Once she fixed the technique the difference was noticeable within days.

Mistake 2 — Touching the bottle tip to your eye or eyelash

I watched patients at Shroff do this constantly. They'd bring the bottle tip so close to their eye that it touched the eyelash or even the eye surface. Every time the staff would stop them and explain why this is a problem.

When the tip touches your eye or lash, bacteria from the surface gets transferred into the bottle. The next time you use that bottle you're potentially putting contaminated drops into your eye. This is especially dangerous after surgery when the eye is healing and more vulnerable to infection.

Keep the bottle about 2-3 centimetres away from your eye. Far enough that the tip doesn't touch anything. Close enough that you can aim into the lower lid pocket. It takes practice but once you get it the habit sticks.

Mistake 3 — Blinking immediately after

Your natural reflex after putting a drop in is to blink. Makes sense because something just entered your eye. But blinking immediately pushes the drop out through your tear drainage system before it has time to absorb into the eye tissue.

After putting the drop in, close your eye gently for about 30 seconds. If you want to increase absorption even more press lightly on the inner corner of your eye near the nose with your finger. This blocks the tear duct temporarily so the medicine stays in contact with the eye surface longer instead of draining into your nose and throat.

This is why some eye drops leave a weird taste in your mouth. The drop is draining from your eye into your nasal passage and down your throat. That's medicine that was meant for your eye ending up in your digestive system. Blocking the tear duct prevents this.

Mistake 4 — Putting multiple drops back to back

This was the biggest issue I saw with post-surgery patients at Shroff who were prescribed 3-4 different drops. They'd line up all the bottles and put them in one after another to get it over with quickly.

The problem is your eye can only hold about 7-10 microlitres of fluid at a time. One drop is already about 30-50 microlitres — most of it overflows immediately. If you put a second drop right after, you're flushing out whatever remained of the first drop before it could absorb. Essentially wasting the first medicine entirely.

The correct gap between different drops is 5-10 minutes. Yes it's annoying when you have 4 drops to put. Yes it turns a 30 second task into a 30 minute task. But each drop needs that absorption window to actually work. My aunt's doctor at Shroff was very particular about this and honestly it was the hardest part of her recovery — not the surgery, the drop schedule discipline.

Mistake 5 — Using drops with dirty hands

Sounds obvious but people forget. You're pulling your eyelid down with a finger that just touched your phone, your keyboard, your doorknob. Bacteria on your finger transfers to your eyelid and potentially into your eye.

Wash your hands before putting drops in. Every single time. Not just after surgery. Every time you use any eye drop. It takes 20 seconds and prevents infections that could take weeks to treat.

Mistake 6 — Storing drops wrong

Some drops need refrigeration. Most people keep all their drops in a bathroom drawer where it's warm and humid — the worst possible environment for medication stability. Some drops lose effectiveness when stored at the wrong temperature. Others grow bacteria faster in warm conditions.

Read the storage instructions on the box. If it says refrigerate, refrigerate. If it says store below 25 degrees, don't keep it in a drawer that gets hot in Delhi summer. After my aunt's surgery she had one drop that needed to be refrigerated and she kept it in the bathroom for three days before I caught it. We replaced it immediately because there was no way to know if the formulation was still effective.

Why technique matters more than people think

Most people who say "eye drops don't work for me" are actually using them wrong. The medicine is fine. The delivery is the problem. Wrong technique means only a fraction of the prescribed dose is actually reaching the eye tissue. Over days and weeks that adds up to significantly less medication than intended.

After watching dozens of patients get corrected at Shroff eye center during my aunt's visits I started paying attention to how I use drops myself. I was making at least three of these mistakes without knowing. Now I do it properly every time and the difference in comfort is noticeable even with basic lubricating drops.

It takes about a week to build the correct habit. After that it becomes automatic. But that first week of consciously slowing down — pulling the lid, aiming for the pocket, closing gently, pressing the tear duct, waiting between drops — feels unnecessarily complicated. It's not. It's just how the medicine was designed to be used.

When my sister was diagnosed with keratoconus at 22 our family had no idea what we were dealing with. We'd never heard the word before. The local eye doctor who'd been prescribing her glasses for years never mentioned it. He just kept giving her new prescriptions every few months when her vision changed.

It took us a while to understand the condition, even longer to find the right hospital for treatment. Delhi has plenty of eye hospitals but keratoconus is a specialised corneal condition and not every hospital handles it the same way. Here's what we learned during the process.

First understand what keratoconus treatment actually involves

Before comparing hospitals I had to understand what we were even looking for. Keratoconus isn't treated with glasses or regular surgery. The cornea is thinning and changing shape progressively. The primary treatment to stop this progression is corneal cross-linking — a procedure where the cornea is strengthened using UV light and riboflavin drops.

Cross-linking doesn't reverse the damage. It stabilises the cornea so the condition stops getting worse. That's an important distinction because some hospitals made it sound like they'd fix everything and others were honest about what cross-linking can and can't do. The honest ones earned our trust faster.

After stabilisation the patient might still need scleral lenses or other visual correction depending on how much distortion has already happened. So the hospital needs to handle both — the cross-linking procedure and the ongoing vision management after.

What actually matters when choosing a hospital

We visited three hospitals in Delhi before deciding. Here's what I learned to look for:

Does the hospital have a dedicated cornea department. Keratoconus is a corneal condition. You need a cornea specialist, not a general ophthalmologist. Some hospitals we visited had excellent cataract and LASIK departments but their cornea expertise was limited. One doctor we consulted spent most of the appointment talking about LASIK alternatives instead of addressing the actual keratoconus. That told us everything we needed to know.

How detailed is the diagnostic evaluation. Keratoconus diagnosis and treatment planning requires specific tests — corneal topography to map the shape of the cornea, pachymetry to measure thickness at multiple points, and slit lamp examination to assess the degree of thinning. A quick power check and a glance at the cornea isn't enough. The hospitals that did thorough imaging gave us much more confidence in their treatment recommendation.

Does the doctor explain the condition honestly. This was big for our family. My sister was terrified after Googling keratoconus and reading worst-case scenarios. She needed a doctor who'd tell her the truth without either scaring her more or falsely promising everything would be perfect. The balance between honesty and reassurance matters when you're dealing with a young patient who just found out her corneas are deteriorating.

What cross-linking technology and protocol do they use. There are different cross-linking protocols — standard and accelerated. The equipment matters. The UV dosage, the riboflavin application method, the exposure time. I didn't understand the technical differences initially but once I researched them I started asking hospitals specifically what protocol they follow and why. The hospitals that could answer this clearly were the ones with actual experience doing the procedure regularly.

Do they offer long-term management beyond cross-linking. Cross-linking is step one. After that my sister needed proper visual correction. Some hospitals treated cross-linking as a one-time fix and didn't have a clear follow-up plan. Others had a structured approach — stabilise first, then assess visual correction options, then regular monitoring. That complete approach mattered because keratoconus is a lifelong condition, not a one-visit problem.

The hospitals we consulted in Delhi

The first was a large chain eye hospital. The doctor confirmed keratoconus and recommended cross-linking. The consultation lasted about 15 minutes. He didn't explain the different protocol options or what to expect after the procedure. When my sister asked "will my vision improve after cross-linking?" he said "yes." That wasn't entirely accurate and we found that out later. Cross-linking stops progression, it doesn't typically improve vision on its own. That oversimplification made us uncomfortable.

The second was a smaller clinic recommended by a family friend. The doctor was knowledgeable and honest but they didn't have the latest cross-linking equipment. He actually suggested we go to a larger centre with better infrastructure for the procedure. We appreciated his honesty.

The third was Shroff Eye Centre in Kailash Colony. This is where we ended up getting my sister treated. The evaluation was the most thorough of the three. Full corneal topography, pachymetry at multiple points, detailed slit lamp examination. The cornea specialist spent about 40 minutes with us — not just examining but explaining.

He showed us my sister's topography maps on screen and pointed out exactly where the thinning was happening and how advanced it was. He explained why cross-linking was necessary now rather than waiting. He was honest that cross-linking would stabilise her cornea but her current vision distortion would need to be managed separately with special lenses. And when my sister asked the same question — "will my vision improve?" — he said "cross-linking will stop things from getting worse. For the vision improvement part we'll work on that after your cornea is stable." That honesty, compared to the first hospital's vague "yes," made our decision easy.

Shroff also had a clear follow-up structure. Cross-linking first, then reassessment after a few months, then discussion about scleral lenses or other visual correction based on how her cornea responded. It wasn't a one-procedure-and-done approach. It was a long-term management plan.

The cross-linking experience

My sister had the procedure done at Shroff on a Saturday. The procedure itself took about an hour. She said it was uncomfortable but not painful. The riboflavin drops sting a bit and keeping your eye open under UV light isn't pleasant but it's tolerable.

Recovery was different from what I expected. Her eye was sensitive and watery for the first few days. Vision was actually slightly worse for about a week because the cornea needs time to heal after cross-linking. Nobody at the first hospital had mentioned this. At Shroff the doctor had warned us in advance so we weren't panicked when it happened.

By week two things started settling. Full healing took about a month. Follow-up scans at month three showed her cornea had stabilised — the topography maps weren't showing further progression. That was the moment our entire family exhaled for the first time since the diagnosis.

The cost reality

Keratoconus treatment cost varies significantly in Delhi. Cross-linking alone ranges roughly from 20,000 to 50,000 per eye depending on the hospital and protocol used. But that's just the procedure cost.

The total cost includes the diagnostic evaluation, the cross-linking procedure, post-procedure medication, follow-up visits over several months, and eventually scleral lenses or other visual correction if needed. Scleral lenses can cost 15,000 to 40,000 per pair and need replacement periodically.

When comparing hospital prices make sure you're comparing the total journey cost, not just the procedure cost. A hospital quoting lower for cross-linking but charging separately for every follow-up visit might end up costing more overall than one that includes follow-ups in the package.

My advice for families going through this

Don't panic at the diagnosis. Keratoconus sounds terrifying when you first Google it but it's manageable with the right treatment. My sister lives a completely normal life now. She works full time, uses her phone, watches movies, does everything she did before.

Find a cornea specialist, not just an eye doctor. This matters more than the hospital name.

Visit at least 2-3 hospitals before committing. The consultation experience will tell you everything. Pay attention to whether the doctor explains or just prescribes. Whether they're honest about what treatment can and can't do. Whether they have a long-term plan or just a one-time procedure.

Don't compare cross-linking prices without understanding what's included. The cheapest option might cost you more in hidden charges over the following months.

And most importantly tell your family member to stop rubbing their eyes. Seriously. This was the first thing every doctor told us and it's the one thing that can accelerate keratoconus progression. My sister had a habit of rubbing her eyes when tired. Breaking that habit was harder than the surgery itself.

I never thought I'd have strong opinions about how hospitals handle prescriptions. Then my aunt had eye surgery and I watched two very different approaches to post-surgery medication within our own extended family. Same city, same type of surgery, completely different experiences. And the difference had nothing to do with the surgery itself.

What happened with my aunt

My aunt had her eye surgery at Shroff Eye Centre earlier this year. After the procedure the doctor sat with us for about 10 minutes and went through every single drop she'd been prescribed. Not just the names. He explained what each one does, why the timing matters, why there needs to be a gap between drops, and specifically why he chose preservative-free formulations for her post-surgical care.

He also asked for her complete medication history before prescribing anything. She takes blood pressure medicine daily. He checked whether any of her post-surgery drops could interact with it. Then he wrote the tapering schedule for her steroid drop on the prescription itself - not verbally, on paper - so there was no confusion about when to reduce and when to stop.

At the time I thought this was standard. This is how it should work everywhere. I'm a pharma student, I know why all of this matters. I assumed every hospital does this.

They don't.

What happened with my cousin's mother-in-law

A few months later my cousin's mother-in-law had cataract surgery at a different hospital in Delhi. Different place, similar procedure. When she came home my cousin called me because her mother-in-law had been handed a prescription with four drops listed and zero explanation about any of them.

No one told her why there needs to be a gap between drops. She was putting all four back to back - basically washing out each medication before it could absorb. No one mentioned that one of the drops was a steroid with a tapering schedule. She was using it at full dose three weeks later because nobody told her to reduce. No one asked about her existing medicines - she's diabetic and takes metformin and a blood thinner daily.

I spent 30 minutes on the phone explaining everything that should have been explained at the hospital. Not because I'm a doctor but because basic medication counselling didn't happen.

The gap is bigger than people realise

After this I started asking around. Friends, relatives, neighbours who'd had surgeries recently. The pattern was consistent. Most people leave hospitals with a prescription they don't fully understand. They know which drops to use but not why, not when exactly, not how to space them, and definitely not when to stop.

The lucky ones have a family member who's in healthcare or who's persistent enough to ask questions. The rest just guess. They put drops whenever they remember. They stop the antibiotic early because their eye feels fine. They continue the steroid at full dose because nobody told them to taper. They use preserved drops on a healing eye surface because nobody explained why preservative-free matters.

From a pharma perspective this is a medication adherence disaster. The surgery can be perfect but if the post-op medication isn't followed correctly the outcome is compromised. And it's not the patient's fault. They weren't given the information they needed.

What good looks like

After watching both experiences I made a mental checklist of what a hospital should be doing with post-surgery medication. Not what would be ideal in a perfect world. What should be the bare minimum.

Explain every drop individually. What it does, how often, for how long. Takes 5 minutes. Most hospitals skip this entirely.

Write the tapering schedule on the prescription. Don't say it verbally and expect the patient to remember. Especially elderly patients. Write it down clearly.

Ask about existing medications before prescribing. Drug interactions are real. A patient on blood thinners getting prescribed a certain eye drop without that check is a risk that's entirely avoidable.

Specify preservative-free where needed. Post-surgical eyes are healing. The preservative in standard drops can irritate the surface and slow recovery. This is basic pharma knowledge but most patients have no idea unless someone tells them.

Demonstrate the correct technique. Sounds obvious but most people put eye drops wrong. They touch the tip to their eye, they blink immediately after, they squeeze out too much. A 2-minute demonstration prevents weeks of incorrect application.

Why this matters beyond eye surgery

This isn't just an eye care problem. This is a healthcare system problem. Doctors are busy. Consultations are short. Prescriptions are written quickly. Patients leave confused. Pharmacies dispense without counselling. And the patient goes home with medicines they don't understand and a recovery that depends on them using those medicines correctly.

What I saw at Shroff during my aunt's treatment should be the standard everywhere. It's not complicated. It doesn't require expensive technology. It just requires someone taking 10 minutes to explain what the patient is putting into their body and why.

If the government ever checks my search history I'm going to have a very hard time explaining myself.

Being a pharma student means Googling things on a daily basis that would make any normal person call the police. I've accepted this. My browser has accepted this. My suggested searches have given up trying to understand me.

Here's a glimpse into what studying pharmaceutical sciences actually looks like from the perspective of a search engine that probably thinks I need help.

The toxicology semester

This was the worst period for my search history. For about three months straight I was Googling things like "lethal dose of paracetamol in humans" and "what happens when you take 50 tablets of ibuprofen" and "organ failure timeline after drug overdose."

I was studying toxicology. It's literally about what happens when drugs go wrong. But explain that to someone looking over your shoulder at a coffee shop when your screen shows "how much aspirin causes death."

My roommate walked in once while I was reading about cyanide poisoning mechanisms for an assignment. She stared at my screen for about 5 seconds and quietly walked out. We didn't talk about it. I think she still watches me a little carefully.

The best part was when I had to calculate LD50 values for different drugs as homework. LD50 is the dose that kills 50% of a test population. I was sitting in the college cafeteria doing math on how much of various substances it takes to kill half a group of rats. The guy at the next table moved.

The drug interactions rabbit hole

Pharmacology class introduced me to drug interactions and now I can't stop. If someone mentions they take two different medicines I immediately start running through potential interactions in my head. It's a reflex I can't turn off.

My search history for this phase includes gems like "what happens if you mix blood thinners with aspirin" and "can antidepressants and migraine pills cause serotonin syndrome" and "fatal drug combinations commonly available over the counter."

I once Googled "which common household medications can kill you if combined" for a presentation on drug safety awareness. The search results were horrifying. The fact that I bookmarked three of them for reference is probably worse.

My mother takes blood pressure medicine and a thyroid supplement. I made her list every single medicine, supplement, and home remedy she uses and then I cross-checked all possible interactions. She thought I was being dramatic. I found one mild interaction nobody had told her about. She doesn't call me dramatic anymore.

The pharmacokinetics phase

This is when you study how drugs move through the body. Absorption, distribution, metabolism, excretion. Sounds boring until you see the search queries it produces.

"How fast does drug X reach the brain after oral administration." "Which drugs cross the blood-brain barrier." "How long does substance Y stay detectable in blood." "Rate of drug elimination through kidneys vs liver."

I sound like I'm planning something. I'm calculating bioavailability for an exam.

There was one assignment where I had to plot drug concentration curves for different administration routes. My search history that week was "intravenous vs intramuscular absorption rate" and "fastest route of drug delivery to bloodstream" and "how quickly do injected drugs take effect." Peak suspicious behaviour for a 22 year old sitting in a college library.

The antimicrobial resistance research

For a project on antibiotic resistance I spent two weeks Googling things like "which bacteria are impossible to treat with current antibiotics" and "superbugs that resist all known drugs" and "what happens when antibiotics stop working globally."

This one didn't just scare my search history. It scared me. The things I learned about antimicrobial resistance are genuinely terrifying. But that's a different blog.

Things I now Google casually that would alarm anyone else

"Therapeutic window of lithium" while eating lunch. "Hepatotoxicity symptoms" while waiting for the bus. "Can you overdose on vitamin D" because my friend said she takes 60,000 IU weekly and I needed to check if she was slowly poisoning herself. She wasn't. But barely.

I also have a habit of reading drug package inserts for fun now. The section on adverse reactions is always wild. A medicine for headaches listing "headache" as a side effect. An anti-nausea drug that may cause nausea. Pharma is full of irony.

The reality behind the scary searches

Every single one of these searches exists because understanding how drugs harm is how you learn to use them safely. You can't be a good pharmacist or pharmaceutical scientist without knowing exactly what happens when things go wrong. The dose that heals and the dose that kills are sometimes not that far apart.

So yes my search history looks like a crime documentary research folder. My bookmarks would concern a therapist. My notes app has drug dosage calculations that look like I'm planning something.

But I promise I'm just trying to pass my exams.

Almost everyone has done this. You find an old bottle of eye drops in your drawer, check the date, it expired two months ago, and think "it's just eye drops, it'll be fine." You use it anyway.

As a pharma student this makes me genuinely uncomfortable because what's happening inside that bottle after expiry is not what most people imagine.

What actually happens when eye drops expire

Eye drops aren't like dry tablets that just lose some potency over time. They're liquid formulations sitting in a moist environment which makes them much more vulnerable to chemical and microbial changes.

The preservative breaks down first. Most multi-dose eye drop bottles contain a preservative, usually benzalkonium chloride, that prevents bacteria from growing inside the bottle. That preservative has a limited effective life. Once it degrades, the bottle becomes a breeding ground for bacteria and fungi. You can't see this happening. The drops look exactly the same. But what you're putting into your eye is no longer sterile.

The active ingredient degrades too. Depending on the drug, it can break down into compounds that weren't part of the original formulation. Some of these degradation products are harmless. Some can irritate the eye surface. In rare cases they can cause a chemical reaction on the corneal tissue, especially if the eye has any existing damage or sensitivity.

The pH shifts over time. Fresh eye drops are formulated to match the pH of your natural tears as closely as possible. As the formulation ages, the pH can drift. Even a small shift means the drops will sting more going in and can irritate the surface with repeated use.

Opened vs unopened — most people don't know the difference

This is something that surprises a lot of people. The expiry date on the box is for an unopened sealed bottle. Once you open it, the clock changes completely.

Most eye drops should be used within 28 to 30 days of opening, regardless of what the printed expiry says. The moment you open the cap, air and bacteria get introduced. Every time you squeeze the bottle and the tip gets close to your eye or eyelash, you're potentially contaminating it further.

So an unopened bottle that expired last month is one problem. An opened bottle that's been sitting on your shelf for three months is a much bigger problem. Even if the printed date says it's technically still valid.

Preservative-free drops have an even shorter window

Single-dose preservative-free vials are designed to be used once and discarded. They have no preservative at all which is great for your eyes but terrible for shelf life once opened. Some people open a vial, use half, and save the rest for later. That leftover liquid has zero protection against contamination.

I learned how critical this distinction is during my aunt's recovery after eye surgery at Shroff Eye Centre. Her doctor specifically prescribed preservative-free drops for post-surgical care because the healing eye surface is more vulnerable to irritation from preservatives. But he also stressed that each vial should be used once and thrown away immediately. No saving for later. No reusing.

At the time I thought he was being overly cautious. Now after studying formulation stability in my coursework I understand exactly why. A preservative-free drop in an opened vial at room temperature can become contaminated within hours. Using that on a post-surgical eye could cause an infection during the most critical healing window.

Why the risk isn't worth it

The eye is one of the most sensitive organs in your body. Its surface is thin, has limited immune defence, and any infection can escalate quickly. An eye infection from contaminated drops can lead to corneal ulcers, chronic inflammation, and in severe cases permanent vision damage.

All of this from drops that "looked fine" and "probably still work."

A fresh bottle of most basic eye drops costs 100 to 300 rupees. A corneal infection costs you weeks of treatment, multiple doctor visits, and potentially lasting damage. The math doesn't support the risk.

What I'd recommend

Write the opening date on every bottle when you first use it. After 28 to 30 days throw it away even if there's liquid left.

Never use drops past the printed expiry regardless of how they look or smell.

Don't save opened preservative-free vials for later. Use once and discard.

Store drops according to instructions. Some need refrigeration. Keeping them in a hot bathroom drawer accelerates degradation.

And if you're recovering from any eye procedure, be extra careful. Your doctor prescribed specific drops for a reason. Using old or contaminated drops during recovery is the worst time to take that risk. The doctors at Shroff eye center were very particular about this during my aunt's follow-ups and now I understand the science behind that caution.

The simple rule
