Comparison of three newer generation freely available intraocular lens power calculation formulae across all axial lengths.

Purpose: The aim of this study is to evaluate the accuracy of three newer generation formulae (Barrett Universal II, EVO, Hill-RBF 2.0) for calculation of power of two standard IOLs-the Acrysof IQ and Tecnis ZCB00 across all axial lengths.

Methods: In this retrospective series, 206 eyes of 206 patients, operated for cataract surgery with above two IOLs over the last 6 months, were included in the study.

Incision size changes after cataract surgery with intraocular lens implantation: comparison of 2 preloaded IOL implantation injectors.

Purpose: To compare incision size enlargement at different times of cataract surgery and visual outcomes after surgery in 2 different intraocular lens (IOL) delivery systems (Vivinex iSert and UltraSert Preloaded IOL Delivery System).

Setting: Tertiary care eye institution.

Design: Prospective nonrandomized comparison study.
