Abstract Details

Purpose:

To compare theeffects of femtosecond assisted LASIK and small incision lenticule extraction (SMILE) on corneal biomechanics.

Setting:

kasr alainy school of medicine,cairo university

Methods:

The study included 60 eyes of patients with myopia or myopic astigmatism presenting for refractive error correction. Femtosecond assisted LASIK group included 30 eyes and SMILE group included 30 eyes. The following tests were done for all patients preoperatively and at 3 months postoperatively: full ophthalmological examination, manifest refraction,UDVA, CDVA, corneal topography CSO topography system (CSO, Firenze, Italy), Corneal biomechanical parameters using Ocular Response Analyzer (ORA; Reichert Inc, Depew, NY).

Results:

The mean value of percentage change of CH Fs-SMILE group was 14.23± 17.59 and in fs-LASIK group was 18.89±7.2 with non-statistically significant difference between both groups (P = 0.1871). The mean value of percentage change of CRF Fs-SMILE group was 27.43± 16.8and in fs-LASIK group was 21.32± 17.1with non-statistically significant difference (P = 0.1682).

Conclusions:

Femtosecond small incision lenticule extraction has no superiority in terms of corneal biomechanical parameters 3 months follow up duration,however contralateral eye comparative studies are needed.
