PURPOSE: To report the clinical results of Small Incision Lenticule Extraction to correct Refractive Errors using a Femto second laser .

SETTING: Medilaser Cataract and Laser Center, Pune, India.

METHODS: The VisuMax Femto second laser system was used to perform Small Incision Lenticule Extraction to treat refractive errors. The laser was used to cut a refractive lenticule intrastromally to correct myopia and myopic astigmatism. The lenticule was then extracted from the stroma through a 3.0mm incision. Outcome measures were corrected distance visual acuity (CDVA), uncorrected distance visual acuity (UDVA), and manifest refraction during 3 months of follow-up and corneal topography.

RESULTS: The study enrolled 89 eyes of 45 patients were studied. The mean spherical equivalent was -5.92 DS ± 2.61 preoperatively and  -0.52 DS 3 months postoperatively. Refractive Stability was achieved within 1 month (P<0.01). Three months after surgery, 92.5%of all full-correction cases had a UDVA of 20/25 or better. The 3-month postoperative CDVA was the same as or better than the preoperative CDVA in 96.05% of eyes. One eye lost 1 line of CDVA.

CONCLUSION: All-in-one Femto second refractive correction using a small incision technique was safe, predictable, and effective in treating myopia and myopic astigmatism.
