Cataract surgery and optimal spherical aberration: as simple as you think?
نویسندگان
چکیده
This paper reviews the optics of higher-order and spherical aberrations and discusses aspheric intraocular lenses, attempting to address 2 questions that, despite an abundance of information, remain unanswered: what amount of ocular spherical aberration has been correlated with optimum visual performance, and for what final amount of spherical aberration should the cataract surgeon aim? Finally, the paper briefly reviews recent publications and makes suggestions for future studies in the area.

Introduction: With the growing and rapid development of refractive surgery, researches focus increasingly on improvement of visual quality after cataract surgery. Intraocular lenses (IOLs) were a successful effort in the field of cataract surgery. Despite significant advances in cataract surgery, several complications related to surgical technique and IOL design after surgery can cause vision c...
متن کاملB&L Aspheric Lenses- the next step in IOL evolution
with a negative spherical aberration designed to compensate for positive spherical aberration found in the cornea of the typical cataract patient. However, these lenses depend on precise positioning. A small offset in centration may result in significant higher order aberrations such as coma, along with significant visual impairment. These negative spherical aberration IOLs are contra-indicated...

PURPOSE To develop a corneal model to better explain how refractive surgery procedures induce spherical aberration. SETTING Department of Ophthalmology and Center for Visual Science, University of Rochester, Rochester, New York, USA. METHODS The preoperative cornea was modeled as a rotationally symmetric surface with various radii of curvature and asphericities. The postoperative cornea was...
متن کاملOptical Quality of Three Multifocal Lenses.
We enjoyed reading the article by Esteve-Taboada et al.,1 but were disappointed by their interpretation of their data. Their optical model has important limitations that make it inappropriate to make broad clinical generalizations from their findings. First, the “aberration-free” eye model is highly artificial. In particular, the absence of any spherical aberration is relevant to only a small p...
متن کاملCorrelation between contrast sensitivity and higher-order aberration based on pupil diameter after cataract surgery
BACKGROUND The purpose of this study was to evaluate the correlation between contrast sensitivity and calculated higher-order aberrations based on individual natural pupil diameter after cataract surgery. METHODS This prospective study included 120 eyes from 92 patients who were randomized to receive one of four lenses, including three aspheric lenses (Acrysof SN60WF, Tecnis ZA9000, and Hoya ...
