Abstract Details

Purpose:

Purpose: The purpose of this study was to analyze and compare the outcome between small-incision lenticule extraction (SMILE) and femtosecond laser in situ keratomileusis (LASIK) (FL) procedures in correcting astigmatism.

Setting:

Dr.Solomatin EYE CARE CENTER, Riga, Latvia.

Methods:

This was a retrospective comparative interventional study comparing the astigmatic outcome between SMILE and FL conducted between June 2015 and December 2018 at a Dr. Solomatin eye care center. Patients older than 18 years of age with ±2 diopters (D) of cylinder were included in the study. Patients with any tomographic abnormalities were excluded. SMILE was performed using the Visumax laser. FL was performed using the Carl Zeiss MEL-90 laser. Outcome parameters included uncorrected visual acuity (UCVA) at final follow-up, residual error(s), and the need for enhancement. Minimum follow-up period was 6 months.

Results:

A hundred eyes each were included in the SMILE and FL groups. The mean cylindrical power was -2,5 Dcyl (range, -2,00 to -4,25 Dcyl) in the SMILE group and -2,75 Dcyl (range, -2,00 to -5,5 Dcyl) in the FLgroup. A total of 95% of eyes achieved UCVA 1,0 or better in the FL group as opposed to 78% in the SMILE group. The mean residual refractive error was -0,25 Dcyl in the SMILE group as compared with -0,07 Dcyl in the FL group. Residual refractive error was noted in 14 eyes of SMILE and 3 eyes of FL.

Conclusions:

Astigmatic correction appears to be closer to target in the FL group as compared to SMILE.
