ABSTRACT This case series evaluates the visual outcomes of two trifocal intraocular lenses, the ZFR00V and TNFT00, in cataract surgery patients. Nineteen patients (38 eyes) were bilaterally implanted with one of the two intraocular lenses. Postoperative assessments included uncorrected and corrected distance, intermediate, and near visual acuities, as well as patient-reported satisfaction and photic phenomena. Both intraocular lenses provided satisfactory visual performance for distance and intermediate vision. However, the ZFR00V intraocular lenses demonstrated superior near vision, particularly in the defocus […]

ABSTRACT Objective To compare the performance of Sanders-Retzlaff-Kraft/Theoretical, Hoffer Q, Barrett Universal II, Kane, and Hill-radial basis function formulas to calculate intraocular lens power in eyes with normal axial length, in terms of predicting target refraction by using partial coherence interferometry technology. Methods Phacoemulsification and intraocular lens implantation were performed in 135 eyes of 135 patients with an axial length between 22 and 24.5 mm. Axial length, keratometry, and anterior chamber depth were measured by intraocular lens Master 500. Sanders-Retzlaff-Kraft/Theoretical, […]

Abstract Purpose: To evaluate six different premium IOLs retrospectively in respect to both subjective and objective refraction after cataract operation. Methods: Five hundreds and seventy eyes of 285 patients with bilateral cataract who had undergone phacoemulsification and IOL implantation operation between February 2017 and September 2018 were enrolled in this study. The mean age of the patients was 57.78 ± 7.49 (41-71) years. Out of 285 patients 137 were male (48.07%) and 148 were female (51.93%). TheIOLsusedare: RayOne Trifocal (Rayner, […]

Abstract Objective: To analyze patients’ quality of life before and after cataract removal surgery associated with intraocular lens (IOL) implantation. Methods: This is an observational, prospective, case series study. Data were collected at a private ophthalmology service in Aracaju – SE, from August 2018 to July 2019. The quality of life assessment of patients before and after 4 months of cataract surgery, using the phacoemulsification technique associated with IOL implantation, was performed by applying the validated Brazilian version of the […]

Abstract Purpose: To assess long, intermediate and near uncorrected visual acuity after a tetrafocal diffractive intraocular lens implantation, presence of dystopic phenomenon and patient satisfaction after surgery. Methods: Retrospective, observational study performed in Puerta de Hierro Specialties Hospital, in Jalisco, México. That included 100 eyes after phacoemulsification surgery by femtosecond assistance, followed by tetrafocal diffractive intraocular lens implantation due to cataract. Long, intermediate and near visual acuity without correction was measured, and presence or absence of dystopic phenomenon, plus patient […]

Purpose: To report the prevalence and analyse corneal astigmatism patterns in cataract surgery candidates. Methods: Researchers examined 2136 eyes from 1204 patients for cataract surgery from 1 January to 31 December 2016. All the candidates were evaluated with partial coherence interferometry (IOLMaster). The results were analysed statistically in relation to qualitative and quantitative variables. Results: The mean age of the patients was 71.9 years with a female predominance. Mean corneal astigmatism was 1.0 dioptre (D). Against the rule (ATR) astigmatism […]

Pediatric cataract is the most common treatable cause of blindness in children. Prevalence, etiology and morphology vary with the socioeconomic development. The treatment goal is to reduce amblyopia, being difficult management especially in unilateral cases. The decision on aphakia or primary intraocular lens should be individualized as well as correction with contact lens or spectacles. The intraocular lens single-piece hydrophobic acrylic are the most implanted in children and the preferably is in the capsular bag. The Sanders-Retzlaff-Kraff theoretic (SRK/T) stressing […]

PURPOSE: Development and validation of quality of life questionnaire in pseudophakic patients in Portuguese. METHODS: The modified Cataract TyPESpecification questionnaire was specifically developed to assess quality of life after cataract surgery, functional status evaluated with 10 items and contains 18 questions. All questions were applied by a single examiner, with the goal of graduating visual satisfaction from 0 to 10 (0 means very dissatisfied, 5 neutral, 10 very satisfied).This prospective comparative study included 142 eyes of 71 patients in Sao […]
