Outcome of Pre-Existing Corneal Astigmatism by Incision at Steep Axis in a tertiary care hospital.
Pak J Med Health Sci Jan ;6(3):683-5.

Purpose: To measure post-surgical astigmatic correction through phacoemulsification at steep axis. Type of study: Quasi-experimental Sampling technique: Non-Randomized consecutive sampling Materials and Methods: This quasi-experimental study was performed on 460 eyes of 350 patients of cataract reporting at Eye Department, Combined Military Hospital (CMH), Lahore from Oct 2010 to Dec 2011 who had pre-existing corneal astigmatism. They were managed by phacoemulsification with corneal incision at steep axis to extract cataract and correct astigmatism. Results: Induced refractive change caused by corneal incision at steep axis showed an overall improvement in pre-operative astigmatism with minimum level of significance Conclusion: Corneal incision at steep axis is an effective technique to reduce pre-operative astigmatism.
