Mögliche Einflussfaktoren für die postoperative Visusprognose bei retroiridaler Irisklauenlinsenimplantation

Abstract

The axial length and preoperative VA affect postoperative visual acuity and visual acuity gain significantly. In eyes with lower preoperative visual acuity and in longer eyes larger visual acuity gain can be expected after retroiridal iris claw lens implantation.

Retropupillary Iris-Claw Intraocular Lenses: A Literature Review

“…Horizontal ovalization of the pupil in the early postoperative phase is observed in a range of 0%-44%. 15 , 17 , 20 , 21 , 23–26 , 28 , 30 , 36–38 , 40–44 , 48–52 , 54–56 This pupil ovalization is mostly temporary and usually pupil dilation is not affected. Toro et al found a temporary (<1 week) pupil ovalization in only 2 (2%) patients.…”

“…However, studies have shown increased postoperative IOP at a frequency of up to 31%. 14–18 , 20 , 21 , 23–28 , 30 , 31 , 33–52 , 54–56 This rise in IOP could be due to the postoperative inflammation and retained viscoelastic in the early postoperative period. 16–18 , 21 , 26–28 , 54 , 55 Dalby et al and Kristianslund et al found no significant differences in the rate of glaucoma or increased IOP in patients who underwent IOL exchange for retropupillary ICIOLs compared with repositioning of the IOL in late in-the-bag IOL dislocation.…”

“…The frequency of CME following ICIOL implantation depends on the indication for surgery and ranges from 0%-25%. 14–18 , 20–32 , 34–39 , 41–44 , 46–56 The duration of follow-up, sample size, and investigative method for CME in different studies also affect the CME rates. Use of OCT at regular follow-ups after cataract surgery might be useful in detecting non-clinical CME (<20/40 change in CDVA).…”
