A prospective study of patients who underwent laser subepithelial keratomileusis (LASEK)

Objective: To compare the preoperative and post-operative unaided visual acuity and assess the post operative complications in patients undergoing LASEK in 2017 and 2018.

Methodology: A prospective study was conducted on 30 eyes that underwent LASEK in 2017 and 2018. Patients were reviewed 6 month post operatively and the residual refractive error and uncorrected visual acuity were assessed. Pre procedure unaided visual acuity and post procedure unaided visual acuity were measured and the improvement of Snellen lines was assessed.

Results: There is no statistically significant difference between the target residual error (-0.50 D spherical equivalent) and the post-operatively achieved final residual error (p < 0.01), the predictability was 100% (residual spherical equivalent is below -0.5D). There is statistically significant difference between preoperative BCVA and post-operative UCVA. (p < 0.01). There is statistically significant difference between pre-operative best corrected visual acuity (BCVA) and post-operative BCVA. (p < 0.05)
