How to Minimize Corneal Astigmatism during Cataract Surgery
Journal Title: Journal of Medical Science And clinical Research - Year 2018, Vol 6, Issue 7
Abstract
Aims: To study the corneal astigmatism in manual small incision cataract surgery following temporal incision, superior incision, superotemporal incision and superior incision with infinity suture. Setting: Government Medical College, Kozhikode; Government Medical College, Palakkad Design: Retrospective Study Material and Method: This study included cases of cataract surgery done during 9 months period from January 2016 to September 2016 at Government Medical College Palakkad. A retrospective Chart review of 199 eyes of 199 patients was done to assess the post operative corneal astigmatism. Visual Acuity & Keratometry was recorded preoperatively and at 2 months post operatively. The results were tabulated into four groups: Superior incision with infinity suture, temporal incision, Superotemporal incision and Superior incision. Postoperative corneal astigmatism, induced corneal astigmatism and post operative visual acuity were analyzed among the four groups. Statistics: SPSS analysis, Microsoft Excel Result: 82 (41.2%) patients had undergone SICS with superior incision, 45 (22.6%) patients had SICS with superior incision with infinity suture, 42(21.1%) patients had undergone SICS with superotemporal incision and 30 (15%) patients had undergone SICS with temporal incision. Post operatively the mean corneal astigmatism at two months was significantly higher in the superior with infinity suture group (1.6444 ±0.640) and superior section group (1.548 ± 0.767) and lowest in the temporal (0.4750 ± 0.401) followed by superotemporal section group (1.035 ± 0.656) The induced corneal astigmatism was lowest in the in the Temporal section group(-0.158 ±0.3181 followed by 0.2917 ±0.6460 in the superotemporal section group and 0.5722 ±0.6563 in the Superior section with infinity suture group and highest in the superior section group ( 0.7622 ±0.7119). This difference in the four groups is found to be statistically significant (p=0.000). Conclusion: Temporal incision induces the least corneal astigmatism followed by superotemporal incision. Highest corneal astigmatism is induced by Superior incision. Infinity suture will help in marginally reducing the corneal astigmatism.
