Abstract

Glaucoma and cataracts, which are major contributors to worldwide blindness, frequently occur together, requiring phacotrabeculectomy as the primary therapeutic approach. This study conducted a retrospective analysis of cases to evaluate the efficacy of Mitomycin-C (0.2mg/ml for 3 min) in phacotrabeculectomy, which is a combination surgical treatment that involves trabeculectomy and phacoemulsification. The study was conducted over six months, from January 2022 to June 2022, in a tertiary care hospital in Salem. An analysis was conducted on the records of 60 patients who underwent phacotrabeculectomy and met the inclusion criteria. The study included 60 patients, with 28 (47%) being men and 32 (53%) being females; of these, 22 (37%) underwent surgery on their right eye, while 38 (63%) underwent surgery on their left. Most patients belonged to the age bracket of 51-65 years. The grading of cataracts identified many forms, such as Nuclear Sclerosis (NS-1: 3%, NS-1 and PSC: 10%, NS-2: 17%, NS-2 and PSC: 23%, NS-3: 7%, PSC: 13%). The most prevalent type, affecting the majority (27%) of the population, was Senile Immature Cataract (SIMC). The average preoperative intraocular pressure was 22.4 ± 1.52 mmHg, and after the surgery, the pressure reduced dramatically to 13.20 ± 1.42 mmHg. The difficulties associated with blebs are resolved on their own. After the operation, there was an improvement in visual acuity. The average values increased from 0.86 ± 0.15 before the surgery to 0.22 ± 0.26 on day 1, 0.20 ± 0.23 on day 7, 0.19 ± 0.23 on day 14, 0.18 ± 0.19 on day 30, and 0.18 ± 0.19 on day 45. A paired t-test demonstrated a statistically significant difference (p=0.02) in postoperative visual acuity between day 1 and day 45. The study's findings indicate that Mitomycin-C is efficacious in phacotrabeculectomy, resulting in decreased intraocular pressure and enhanced visual acuity, with no notable problems. The findings provide valuable insights into managing concurrent glaucoma and cataracts, presenting a viable strategy in tertiary care settings.
