Introduction

Presbyopia is a condition of the eye in which there is a gradual loss of the ability of the eye to focus clearly on a nearby object. One may notice presbyopia while holding a book or a newspaper at a normal reading distance to see.

Presbyopia is generally an annoying part of ageing that becomes noticeable in the early 40s and becomes worse at the age of 65. Presbyopia can be diagnosed by an eye examination. It can be corrected by eyeglasses or contact lenses.

However, people also consider advanced surgery for presbyopia such as PresbyLASIK. It is a quick procedure and requires less recovery time. The good thing about presbyLASIK is that it offers the reversal of the process if the patient does not get expected results.

PresbyLASIK does not get the approval of use from the FDA in the United States, however, it has been practiced for several years in Canada.

PRESBYLASIK

PresbyLASIK is a surgical correction for presbyopia. It is an advanced form of LASIK surgery. PresbyLASIK sometimes also called Multifocal LASIK reshapes the eye’s cornea and creates the unique power zones for near, far and intermediate vision.

The unique power zones offer better vision and eliminate blurriness for near .This procedure can allow the brain to process better visual information. This can be achieved by applying different curves to the contact lens.

When To Opt For PRESBYLASIK?

The ideal candidate for presbyLASIK is the patient with early presbyopia of age 40-55 years. The lenses of the patient can be replaced by a multifocal bifocal or Trifocal lens and this intraocular surgery is called PRELEX surgery and it seems to have promising results and lasts longer than corneal refractive surgery.

What Is The Procedure For PRESBYLASIK?

The procedure includes an excimer laser that reshapes the cornea carefully. It modifies the shape of the cornea by creating unique zones for near-vision, far-vision and intermediate vision.

Light is bent or refracted differently in each zone that helps near vision to recover from presbyopia.

PresbyLASIK can be done on both the eyes or on only one eye to create a correction of presbyopia.

What Are The Side Effects Or Post-Operative Discomfort Of PRESBYLASIK?

Most of the patients get 20/20 or 20/25 distance vision. The patient can easily read books and newspaper without using glasses. But people can also experience some side effects after the surgery.

The distance vision may be blurry if the patient has normal vision except presbyopia before multifocal LASIK.

Some patients also witnesses reduced contrast sensitivity.

Loss of contrast sensitivity caused by presbyLASIK may be temporary.

The patient may also develop a cataract after the presbyLASIK. But it does not interfere with surgery for the removal of the cataract.

It is also associated with reduced quality of vision.

Is There Any Process For Reversing PRESBYLASIK?

Yes, presbyLASIK offers the reversal of the procedure if the patient can’t get desirable results. It has a great potential for people of age more than 45 years.

The LASIK enhancement procedure can correct your distance vision completely but it is possible that for your near vision you will need to wear glasses like while reading a book or newspaper.

How Effective Is PRESBYLASIK?

Many studies have shown that patients get 20/20 0r 20/25 distance vision. The patients are also able to read well without glasses. However, there may be some side effects of this procedure such as:

The patient might suffer from blurry distance vision.

The patient may also develop a cataract after the surgery.

It is possible that the patient can experience loss of contrast sensitivity.

The patient can have difficulty seeing coloured objects placed at a specific distance.

It is also possible that the patient may need to wear eyeglasses even after the surgery.

In some cases, presbyopia continues to evolve and the technique gradually loses its efficacy over time.

Finally, it is concluded that there is no guarantee that multifocal LASIK surgery can give you permanent treatment. Perhaps, you need further surgical enhancements, if your vision changes few years after your LASIK surgery.

Conclusion

PresbyLASIK has a lack of strong scientific evidence. It could have a promising future but currently, the application of presbyLASIK is temporary in nature. The achievement of a stable multifocal cornea with long term results is still a challenge. A complete eye evaluation and examination is the best way to know whether presbyLASIK is the correct option for you or not. Your doctor will discuss all the possible side effects and benefits regarding the PresbyLASIK surgery. You can also seek advice for all the other options that are available to treat presbyopia so as to improve your vision.
