Visual Acuity After Using A New Monofocal Intraocular Lens Compared To Standard Monofocal Lens

Kasr El Aini Hospital20 enrolled

Overview

This is a prospective comparative interventional clinical study, that took place from January 2021 to November 2021. Twenty patients (20) were enrolled in this study 10 patients in each group. It was designed for comparison of uncorrected and best corrected distance and intermediate vision in patients whom implanted with monofocal Tecnis Eyhance or Tecnis 1-piece IOLs.

Purpose To determine the Uncorrected and best-corrected distance, and intermediate visual acuity in a new innovative monofocal intraocular lens compared with standard monofocal lens. Methods This is a prospective comparative interventional clinical study, that took place from January 2021 to November 2021. 40 eyes of Twenty patients (20) were enrolled in this study, patients who are candidates for cataract extraction by phacoemulsification were included in this study and underwent thorough preoperative examination and post-operative evaluation at 3 months after the 2nd eye operation, of distance, intermediate, near add, contrast sensitivity and incidence of photic phenomena using a printed questionnaire for evaluating this incidence and binocular defocus curves were analyzed.

Outcomes

Primary Outcomes

Uncorrected and best-corrected distance, and intermediate visual acuity.

Distance visual acuities were examined by ETDRS chart and intermediate and near visual acuity by Jaeger chart at 66 cm and 33 cm respectively.Measured values of the visual acuity were expressed in decimal values and converted to logMAR values.

Time frame: 3 months post operative

Secondary Outcomes

Contrast sensitivity

Contrast sensitivity was measured using Pelli Robson illuminated chart at 1m

Time frame: 3 months post operative
