PURPOSE: To assess the safety and efficacy of Manual Small Incision Cataract Surgery (MSICS) in cases of white cataract with the use of trypan blue as an adjunct for performing continuous curvilinear capsulorthexis (CCC). MATERIALS AND METHODS: Prospective observational study on 100 consecutive eyes of 100 patients with white cataract who had undergone MSICS with trypan blue assisted CCC. The nucleus was prolapsed into anterior chamber by using a sinskey hook and extracted out of the eye using irrigating vectis. Intraoperative and postoperative findings (according to OCTET classification) as well as postoperative visual outcomes were used as main measures to report the safety and efficacy of the surgery. RESULTS: Of the 100 eyes, 16 had intumescent, 67 had mature and 17 had hypermature cataract. Intraoperatively CCC was incomplete in 4 eyes (4%) and had to be converted to canopener capsulotomy. None of the eyes had posterior capsular rupture or zonular dialysis and no eyes were converted to conventional Extra Capsular Cataract Extraction (ECCE). Postoperatively, 6 eyes (6%) developed corneal oedema with >10 Descemets folds and 7 eyes (7%) had corneal oedema with < 10 Descemets folds. Mild iritis was seen in 6 eyes (6%) and moderate iritis with fibrin membrane was seen in 3 eyes (3%). Iridodialysis was observed in 1 eye (1%). Of the 99 patients (99%) categorised under good visual outcomes category, 94 patients (94%) had a best-corrected visual acuity of 6/9 or better on the 40th post-operative day. CONCLUSION: In developing countries like India where phacoemulsification may not be affordable to a majority of those requiring cataract surgery, MSICS proves to be a safe and efficacious alternative for white cataracts especially with the adjunctive use of trypan blue dye.
