To evaluate the change in corneal higher order aberrations after Microincision Cataract surgery (MICS).
In a prospective case series, 20 patients (40 eyes) with bilateral age-related cataract underwent MICS through a 1.8 mm clear corneal incision. An aspherical single-piece lens AcriSmart ® was implanted. Corneal topography and aberrations were measured and not calculated before and 3 months after surgery with the Topograph Atlas 9000 ® (Carl Zeiss, Meditec USA).
Preliminary results of the 20 first eyes : surgery did not change measured corneal spherical-like aberration (preoperative / postoperative, 0.266 +/- 0.07 vs 0.233 +/- 0.08, p = 0,78), coma-like aberration (preoperative/ 3-month postoperative, 0.039 +/- 0.28 vs 0.051 +/- 0.21, p =0,44) and corneal trefoil-like aberration (preoperative / postoperative, -0.061 +/- 0.39 vs -0.089 +/- 0.28, p = 0,121). Corneal astigmatism was not different between pre et postoperative measurement. Mean pupil diameter was 4.6 mm (+/- 0,8) in pre and postoperative.
Microincision cataract surgery did not seem to induce any corneal changes in postoperative measurement of corneal aberrations.
