Comparison of 3 Diffractive IOLs in 3 Wavelengths Bifocal / Trifocal/EDOF. Gatinel, Pagoulle, Gobin, Loicq J L C D. ASCRS meeting, 2016, May 10th

This paper focuses on the objective comparison of three premium intraocular lenses (IOLs): one said monofocal achromatic with extended depth of focus (EDOF), one diffractive bifocal, trifocal one rosea. All IOLs are made with year face material.     Abstract: Purpose To describe the optical performance of 3 types of face diffractive intraocular [...]

Presby-LASIK for presbyopia surgery

Presbyopia surgery can be performed thanks to the technique of LASIK. The term "presby-LASIK" is dedicated by usage, but it does not match a univocal strategy of lens correction in presbyopic subjects. Presby-LASIK; definition (s) strictly speaking, presby-LASIK is the realization of a refractive correction in LASIK in a far-sighted subject, [...]

Courtin R, Saad has, Gatinel D. Procedure of multifocal presbyLASIK: aspherisation and principle of negative addition. Images in ophthalmology, flight VIII No. 6, December 2014

This article outlines the principles put in game for the surgical correction of presbyopia in a 51-year-old patient, low hyperopic and presbyopic. A LASIK were made on both sides. The non-dominant eye has benefited from a program combining the amount of hyperopia and presbyopia, and modulation of the corneal Asphericity [...]

Download:JRSOnline06GATINEL(1) this article is devoted to the study of the relationship between changes in the Asphericity and those of the spherical aberration of corneal origin. Presbyopia refractive surgery, most of the multifocal LASIK (presbyLASIK) corrections are based on correction of defocus (D) possible, and a modulation of the corneal Asphericity (Q) to induce a [...]

D Gatinel. Choosing the Mode of Presbyopia Correction. RSPC Europe - October 2013

Choice of a technique for correction of presbyopia. This article is devoted to the review of current options for presbyopia surgery. Operations to correct presbyopia can be performed on the cornea (ex: presby LASIK) or on the lens (ex: the lens removal and replacement with a multifocal implant). They are [...]

Intracor

Relaxing corneal surgery: the "Intracor" technique. This technique is still proposed in some centres in France and abroad. It was introduced as a "revolution" for the treatment of presbyopia in some media (press, TV, ect ...), before a certain unpredictability in the clinical results in the short medium term did not come to temper the enthusiasm [...]
