Abstract

Posterior corneal change is being implicated for residual MRSE post-refractive surgery. A single-center prospective trial to observe the changes following SMILE for a follow-up period of 3 months to study the changes in posterior corneal curvature in participants undergoing SMILE for myopia. 248 eyes of 124 participants were analyzed while assigned into mild, moderate and high group based on the amount of MRSE. The posterior keratometric readings increased significantly among all the groups at the postoperative 1-week follow-up with p-value less than 0.001 in all three groups, which did not change significantly at 1-month and 3-month. An increase in the negative dioptric power of a posterior surface is significantly related to higher residual MRSE in the mild myopia group (r=0.301, p=0.007), while the correlation was not significant in moderate and high myopia group. The posterior corneal curvature change following SMILE thus plays a contributing role in residual MRSE.
