Scleral buckling and pars plana vitrectomy for rhegmatogenous retinal detachment: an analysis of 542 eyes.

Purpose: To investigate the anatomical success rates of scleral buckling (SB) and pars plana vitrectomy (PPV) performed for rhegmatogenous retinal detachment (RRD) in a large case series and to identify prognostic factors for the primary anatomical success rates of surgical techniques.

Methods: We reviewed 542 consecutive eyes for primary RRD in this retrospective study. Follow-ups were performed for at least six months.

Intraindividual comparison of visual performance after posterior chamber phakic intraocular lens with and without a central hole implantation for moderate to high myopia.

Purpose: To compare postoperative visual performance after implantable Collamer lenses with and without a central hole (Hole ICL and conventional ICL) are implanted to correct moderate to high myopia.

Design: Prospective intraindividual comparative study.

Patients And Methods: This study evaluated 58 eyes of 29 patients with spherical equivalents of -7.

Early clinical outcomes of implantation of posterior chamber phakic intraocular lens with a central hole (Hole ICL) for moderate to high myopia.

Aim: To assess the early clinical outcomes of an ICL with a central hole (Hole ICL) implantation for the correction of moderate to high myopia.

Methods: This study evaluated 20 eyes of 20 patients with spherical equivalents of -7.36 ± 2.

Crystalline lens changes in porcine eyes with implanted phakic IOL (ICL) with a central hole.

Background: We calculated the smallest diameter of a hole in the center of the optic at which the optical character of a phakic IOL (ICL) may be maintained. The changes induced in the aqueous humor dynamics and the pathology of cataract development with such a hole were investigated.

Methods: A simulation was performed using ZEMAX software to calculate the hole diameter that makes possible the maintenance of a stable optical character of a phakic IOL.
