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 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 کاملRemoval of corneal epithelium with phototherapeutic technique during multizone, multipass photorefractive keratectomy.
BACKGROUND The therapeutic mode of the VISX 20/20 excimer laser was used to remove the corneal epithelium prior to performing photorefractive keratectomy (PRK) with a multizone, multipass technique. METHODS A retrospective analysis was performed of 120 eyes of 90 patients that were treated for preoperative spherical refractive errors from -1.00 to -7.00 diopters (D) (mean -3.90 D, SD 1.54) by...
متن کاملInduced optical aberrations following formation of a laser in situ keratomileusis flap.
PURPOSE To determine how refractive error, visual acuity, and high-order aberrations (3rd- and 4th-order) are affected by the formation of a lamellar corneal flap during laser in situ keratomileusis (LASIK). SETTING University refractive surgery center. METHODS The effect of lamellar corneal flap formation was analyzed in 15 myopic eyes (mean preoperative refraction -4.72 diopters [D] [rang...
