To report three months results of femtosecond-assisted small-incision lenticule extraction (SMILE) for myopia and myopic astigmatism.

Data from 122 eyes from 66 patients will be reviewed for 3 months results by January 31, 2015. An intrastromal lenticule was cut by VisuMax (Zeiss-Meditec) femtosecond laser and manually extracted. Uncorrected distance and corrected visual  acuity (UDVA and DCVA), manifest refraction (sphere, cylinder and axis) data, spherical equivalent, along with front and back corneal elevation (BFS 8mm) and 4 and 6mm spherical aberration data.

Average age was 34 years old (range 18-65). 41.8% were male. The mean preoperative manifest sphere was – 5.08 diopters (D) ± 1.61 (SD) (range -2.25 D- -10.00 D); and the mean preoperative manifest cylinder was -0.74 diopters (DC) ± 0.73 (SD) (range 0- -4.25 DC).The mean preoperative spherical equivalent was – 5.45 diopters (D) ± 1.65 (SD) (range -2.75 - -10.75 D). Three months after SMILE, 100% of eyes had UDVA of 20/40 or better, 92% had 20/25 or better and 78% had 20/20 or better; 97% of eyes were within 1D and 84% of eyes were within 0.5D of intended correction. Clinical and corneal tomography 6 months results will be provided by January 31, 2015.

Relex SMILE is an efficacious refractive treatment for myopic astigmatism.
