Outcome of Pre-existing Corneal Astigmatism after Phacoemusification by Scleral Tunnel Incision.
Pak J Med Health Sci Jan ;7(1):54-7.

Aim: To measure post-surgical astigmatic induced by scleral tunnel incision Type of study: Quasi-experimental Sampling technique: Non-Randomized consecutive sampling Materials and methods: This quasi-experimental study was performed on 90 eyes of 90 patients of cataract reporting at Eye Department, Combined Military Hospital (CMH), Lahore from Sep 2011 to June 2012 who had pre-existing corneal astigmatism. They were managed by phacoemulsification with scleral tunnel incision to extract cataract and correct astigmatism. Results: Induced refractive change caused by scleral tunnel incision and effect on pre-operative astigmatism was minimal keeping minimum level of significance Conclusion: Scleral tunnel incision is an effective technique to maintain astigmatic neutrality.
