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.
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.
