Abstract Details

Purpose:

To report the 12-months results of first 60 fully seeing eyes treated for myopia with a new method of refractive correction, Small Incision femtosecond Lenticule Extraction SMILE. In a recent study SMILE is investigated in terms of stability, safety, efficacy, predictability and HO spherical aberration changes.

Setting:

Dr. Solomatin Eye Center

Methods:

This prospective clinical trial comprised 60 eyes from 30 patients. The mean age was 29 years. The pseudoflap and a lenticule of intrastromal corneal tissue were cut simultaneously using a femtosecond laser VisuMax. The lenticules were removed from the corneal tissue throw the small incision 3.2-4.0mm. Patients preoperative data SEQ Preop Mean -4,57 D ±1,32 D Range -2.0 D to -9.0 D Sph Preop Mean -4,37 D ±1,34 D Range -2.0D to -8,25 D Cyl Preop Mean -0,41 D ±0,51 D Range 0 D to -3.0 D Investigation protocol: Follow up: preoperative and postop (1 day , 1 week, 1 month, 3 months, 6 months, 12 months)

Results:

: 12 months postoperatively, the mean SE was -0.12±0.34 D and were within ± 0.5 D in 96.0% 25% (15) of treated eyes gained 1 line, 65% (39) no changed, 10 % (6 eyes) lost 1 line and no eye lost 2 lines. NCVA 20/20 was in 92 % of eyes, UCVA 20/16 in 39%.The spherical aberration postop was Z4;0 -0.084±0.20 .

Conclusions:

The SMILE procedure for correcting the myopia shows good results in terms of efficacy, stability and safety, with few adverse events and less induction of spherical aberration. A one- laser system would decrease the cost of the procedure. SMILE potentially safer for biomechanical structure of cornea. The femtosecond laser cutting action is more independent on corneal hydratation and another fluency rates.
