Comparative study of outcome of capsulorhexis by assisted capsulorhexis device versus manual capsulorhexis in cataract surgery

Abstract

Cataract is the major cause of treatable blindness in India (62.6%). Quality cataract surgery is basic need of the cataract blind patient. Phacoemulsification and SICS are routine surgery performed for cataract in developing countries. Continuous Curvilinear Capsulorhexis is the most important pre-requisite for successful outcome of cataract surgery.To evaluate early outcome of assisted capsulorhexis versus manual capsulorhexis in cataract surgery. This descriptive observational study was carried out during January 2017 to October 2018 with purposive sampling of 100 cases.Mean age of the study population was 60±9.1 in which 84% patients had immature cataract, while 16% patients had mature cataract. The cases operated by phacoemulsification surgery using manual technique 76% had regular shape of CCC and with assisted technique 84% had regular shape of CCC. Among patients operated with SICS using manual technique, 16% cases had regular shape of CCC and with use of assisted capsulorhexis device, 80% had regular shaped CCC. A statistically significant association was found between assisted technique and centration of the CCC (p=0.00001). The assisted capsulorhexis device (VERUS) was found to be effective in achieving optimal size, circularity and centration of CCC during cataract surgery.
