Abstract Details

Purpose:

To report six months results of refractive lenticule extraction through a small incision (ReLEx SMILE) for correction of myopia and myopic astigmatism.

Setting:

Prasad netralaya Private super speciality tertiary eye hospital

Methods:

Sixty eyes of 30 patients with spherical equivalent of -3.15�â�€�‰�Â�±�â�€�‰1.47 D who underwent routine ReLEx SMILE by a single surgeon were Prospectively followed-up for six months. We used the VisuMax femtosecond laser system (Carl Zeiss Meditec AG, Germany) with a 500 kHz repetition rate. Follow-up intervals were at 1 day, 1 week, 1, 3, 6 months after surgery. Following parameters were taken: incision size (4 mm), uncorrected (UDVA) and distance-corrected visual acuity (CDVA), contrast sensitivity, and wave front measurements were noted. We also recorded all complications noted during surgery.

Results:

Suction loss, flap tear, lenticule tear and incomplete dissection in 4eyes, 6months results were obtained in 56 eyes. After 6 months, 83% of eyes had an UDVA of 20/20 or better. 12% eyes lost 1 line of CDVA, while 26% gained 1line and 2% gained 2lines. The mean SE after 6 months was -0.31�â�€�‰�Â�±�â�€�‰0.17. The mean refraction change between month 1 and 6months was 0.11 D.Contrast sensitivity did'nt show significant changes. The HOA increased from 0.16 to 0.32 �Î�¼m(WASCA) and the mean spherical aberrations changed from 0.311 to 0.439 at 6mm pupil(VISANTE) .Residual error remained in 1 patient.

Conclusions:

ReLEx SMILE produced exceptional refractive outcomes with moderate induction of HOA and unaffected contrast sensitivity after 6 months.
