🔎 FINDING THE BEST #TONOMETER FOR YOUR PRACTICE – IOP IN #OPTOMETRY & #OPHTHALMOLOGY It’s easy to get lost while looking for the #BestTonometer as there are a few #tonometry options: #applanation, handheld, desktop, #noncontact, #airpuff, rebound, indentation, non-corneal, through the eyelid / transpalpebral, scleral, pen-like tonometers. There is also a list of manufactures to pick from: HAAG-STREIT, 66Vision, Canon, Cso, #DIATON, Huvitz, Essilor, Icare, Luneau, Kangjie, Keeler, Kowa, Macro, Nidek, Oculus, Reichert, Rexxam, Rodenstock, Swowei, Tomey, Accutome, Topcon, Ziemer just to name a few. Each tonometry device has its benefits, advantages and limitations. #Tonometrydevices can be broken up to 2 Main Categories: #Corneal Tonometry – where intraocular pressure (IOP) is measured by either indenting or applanating the cornea. Contact with the cornea and numbing drops might be required with some corneal tonometers (ex: Goldmann, Tonopen) and not others, such as Airpuff. Non-Corneal or #Scleral Tonometry – this innovative tonometry category is represented by a single brand the Transpalpebral DIATON tonometer. Diaton presents an innovation due to its technique and ballistic principle, which is based on Newton’s second law of motions: Fnet = m • aDiaton tonometer allows to measure IOP through the upper eyelid and sclera. Unlike all other #cornea dependent tonometry devices, IOP with Diaton is not influenced by known and still unknown biometric properties of the cornea. #Pachymetry is not required to adjust the readings for the #centralcornealthickness (CCT), as with Diaton device, the operating principle and the technique completely eliminates the influence of the cornea. #IOP is measured above the edge of the #limbus, with Diaton #tonometers tip placed on the upper #eyelid at #tarsus and sclera. https://tonometerdiaton.com/2017/10/🔎-best-tonometer-practice-iop-optometry-ophthalmology/ Tonometer Diaton is the perfect solution in the following cases when the use of other tonometry devices is problematic or impossible: #Keratitis, #Conjunctivitis, #Keratotone, Cornea Dimness, #Keratoprosthesis, #Keratoplastics, #LASIK, LASEK, #PRK, #Astigmatism, #Ametropy (at New York, New York) https://www.instagram.com/p/BqY70AIlf_H/?utm_source=ig_tumblr_share&igshid=mbxxzfapejpd
