Abstract Details


To describe a case of unilateral corneal ectasia in a patient following Small Incision Lenticule Extraction (SMILE) and the subsequent management


A tertiary eye care hospital in north India


We describe a case of corneal ectasia in a 26 year old male following SMILE. Preoperative corneal topography was normal with a minimum corneal thickness of 511 and 513 microns in the right and left eye respectively. Lenticules of 85 and 82 microns were fashioned to offer a refractive correction of -3.75D sphere with -1.50D cylinder and -3.50D sphere with -1.50D cylinder respectively. Twelve months following surgery he presented with early signs of ectasia in the left eye on corneal topography which had worsened at 18 months follow up. He underwent Intracorneal ring segment implantation with corneal collagen cross-linking.


We report the first case of unilateral corneal ectasia following SMILE in a patient with a normal preoperative corneal topography . Two cases of bilateral ectasia have been reported previously. However, the patients had forme fruste keratoconus on preoperative topography.


Further studies are required to obtain more information on the biomechanical corneal changes that occur following this refractive procedure. Moreover, preoperative screening for patient selection in SMILE should be as stringent as that for LASIK correction.
