Prophylactic Circumferential Retinal Cryopexy to Prevent Pseudophakic Retinal Detachment after Posterior Capsule Rupture during Phacoemulsification

Purpose. to evaluate whether prophylactic circumferential retinal cryopexy (crc) can prevent pseudophakic retinal detachment (prd) development after posterior capsule rupture (pcr) during phacoemulsification. methods. retrospective patient chart analysis of eyes experiencing a pcr during phacoemulsification. comparison of prd development between eyes receiving crc (cryo+ group) or not (cryo- group). results. overall 106 patients were analyzed,thereof 61 (58%) in the cryo+ and 45 (42%) in the cryo- group. in both clusters a total of 10 prds (9.4%) occurred,thereof 3 (30%) in the cryo+ as well as 7 (70%) in the cryo- group (p = 0.087),79.8 ± 81.58 weeks after pcr. relative/absolute risk reduction in crc-treated eyes was calculated to be 68%/11%. prophylactic crc reduced prd development 0.3-fold. number needed to treat was estimated to be 9.4. conclusion. prophylactic crc might be a useful treatment option in eyes with pcr to hamper prd development in the further course. further research is indicated to evaluate this beneficial effect between eyes with and without a rupture of the anterior vitreous cortex and accompanying vitreous loss in an expanding number of eyes. © 2015 t. bertelmann et al.
