In-the-bag decentration of an intraocular lens in a patient with a tendency to hypertrophic scarring [PDF]

open access: yesDigital Journal of Ophthalmology, 2016
We report a case of rapid anterior lens capsular contraction leading to decentration of a hydrophilic acrylic lens with stiff haptics (Rayner design). To our knowledge, this is the first report to investigate early capsular contraction with folding of the haptic over the optic in a patient with a tendency toward hypertrophic scar formation.

Intraocular lens tilt and decentration after Nd:YAG laser posterior capsulotomy: Femtosecond laser capsulorhexis versus manual capsulorhexis

open access: yes, 2019
Purpose: To compare intraocular lens (IOL) tilt and decentration after Nd:YAG laser posterior capsulotomy in eyes that had femtosecond laser–assisted capsulotomy versus manual capsulorhexis. Setting: Ekol Eye Hospital, Izmir, Turkey.

Optical performance of a new design of trifocal intraocular lens based on the Devil's diffractive lens

open access: yes, 2023
In this work, we propose a new diffractive trifocal intraocular lens design with focus extension, conceived to provide a high visual performance at intermediate distances. This design is based on a fractal structure known as the "Devil's staircase".

Effects of capsulorhexis size and position on post-surgical IOL alignment

open access: yesScientific Reports
In cataract surgery, post-surgical stability of the intraocular lens plays a major role. This study aims to explore how the size and decentration of the capsulorhexis affect intraocular lens decentration and tilt by using numerical methods.
