Investigation of visual acuity and residual refractive error after cataract surgery in patients with senile cataract by phacoemulsification
Background and Aim: Vision improvement and reduction of refractive errors are considered as important goals of cataract surgery. The purpose of this study was to evaluate residual refractive errors after cataract surgery in the patients with senile cataract in Shahid Rahimi Hospital in Khorramabad City between 2017 and 2018. Material and Methods: This cross-sectional study included 178 patients...
متن کاملVisual and Refractive Results of Cataract Surgery by Phacoemulsification Method in Patients with Keratoconus
Purpose: To examine the visual and refractive results of cataract surgery by phacoemulsification method in patients with keratoconus. Methods: In this retrospective study, the files of patients with keratoconus, who underwent phacoemulsification between 2008 and 2017, were evaluated. The intraocular lens power calculation formula was SRK/T. Post-operative visual and refractive results were anal...
متن کاملRefractive Error and Anterior Segment Parametric Changes in Patients with Posterior Capsular Opacification after Nd: YAG Laser Posterior Capsulotomy
Background and Objective: Cataract is one of the most common causes of blindness in the world, and posterior capsular opacification (PCO) is the most common complication after cataract surgery. Nd: YAG laser posterior capsulotomy is a standard method for the treatment of PCO. The aim of this study was to investigate the effects of Yas laser capsulotomy on anterior segment parameters and lenticu...
متن کاملA Quantitative Investigation on the Effect of Edge Enhancement for Improving Visual Acuity at Different Levels of Contrast
Background: The major limitation in human vision is refractive error. Auxiliary equipment and methods for these people are not always available. In addition, limited range of accommodation in adult people when switching from a far point to a near point is not simply possible. In this paper, we are looking for solutions to use the facilities of digital image processing and displaying to improve ...
متن کاملChange in refractive status of the patients undergoing phacoemulsification surgery.
This study was carried out with the objective of finding refractive status of patients undergoing phacoemulsification surgery for cataract extraction. Success of cataract surgery can be quantified with the improvement in visual acuity with least amount of refractive error. Prospective study of 44 patients was done pre operatively and with subsequent follow up in the first, third and eighth week...
