Abstract
Angle kappa is an important factor for success of premium IOLs. Patients who underwent SMILE in last decade need cataract surgeries and IOL implantation in next coming few decades. A single-centre, prospective, observational comparative study evaluated changes in angle kappa in participants undergoing SMILE for a follow-up period of 3 months. 248 eyes of 124 participants were analyzed. Corneal topography & angle kappa were measured using OrbScan IIz at pre-op and 3 months post-op. Shapiro-Wilk test established normalcy. Paired t-test & Pearson’s Correlation was calculated. In 131 eyes, angle kappa increased significantly (4.75±1.1° to 5.24±1.2°) while in 117 eyes it decreased significantly (5.02±1.4° to 4.52±1.4°). Changes in angle kappa had a significant negative correlation with lenticule thickness(p<0.01) & simulated keratometry readings(p=0.33). An increase in angle kappa may hamper the optimal outcomes in the patients undergoing SMILE now and will demand premium IOLs later in life
