- to study possibility of the safe primary posterior capsulorhexis, - to evaluate results after this surgery procedure in patients with PEX.
Multidisciplinary Science and Technology Complex Eye Microsurgery named after Academician S. N. Fyodorov, Federal State Institution, Novosibirsk Branch, Russia
There were 162 eyes of 149patients (male 53, female 96). The age of these patients ranged from 51 to 84years. The diagnosis a cataract with PEX was noted at all patients. All surgical procedure was performed in period from October 2011 to March 2013 and include: phacoemulsification of cataract, primary posterior capsulorhexis, implantation of a capsular tension ring (CTR) and intraocular lenses (foldable hydrophobic (138) and hydrophilic (24) IOL). The technique features of a primary posterior capsulorhexis were prior implantation of a CTR for stabilization of the capsular bag, injection of the minimum quantity of cohesive viscoelastics under a capsule ( only in a perforation zone).
The primary posterior capsulorhexis was performed without any complications. The procedure provided high and stable visual acuity in all cases. No cases of cystoid macular edema (CME) were noted. In the early post-op period three cases of high intraocular pressure were observed and normalized by instillations.
The primary posterior capsulorhexis is a safe procedure. This method seems to be effective way to prevent PCO and can be recommended as standard procedure during PEX cataract surgery.
