Prospective Clinical Trial of Unilateral or Bilateral Implantation of TecnisSymfony IOL in Cataract Patients With Presbyopia

Cataract Clinical Trial

Official title: Prospective Clinical Trial of Unilateral or Bilateral Implantation of the Enlarged Depth-of-focus Intraocular Lens in Cataract Patients With Presbyopia

Status Active, not recruiting

Clinical Trial Summary

This is to evaluate the satisfaction of patient and physician about short-distance, medium-distance, long-distance postoperative vision and eyeglass dependence, glare, and visual acuity after insertion of the TECNIS® Symfony or TECNIS® Symfony Toric intraocular lens.

Clinical Trial Description

The patients underwent uneventful phacoemulsification and implantation of TecnisSymfony®. Mean absolute error (MAE) at 1 month was compared in SRK/T, Holladay2, Haigis, Hoffer Q, Barrett Universal II, and Hill-RBF formula. At postoperative 1, 4, and 12 weeks, logMAR visual acuity (logMARVA) at the distance (5m), intermediate (66cm), and near (40cm), and spherical equivalent (SE) in manifested refraction (MR) and automated refraction (AR) were measured. Wavefront aberration, contrast sensitivity test, and glare test were done at 12 weeks. The questionnaire was used to investigate glare, glasses dependency, and patient satisfaction at 12 weeks. ;
