Abstract Details

Purpose:

To report the initial experience in a general practice setting with Small Incision Lenticule Extraction (SMILE) in North America

Setting:

The study took place in the refractive surgery clinic of a general practice of the first commercial user of the SMILE technology in North America.

Methods:

Prospectively patients were enrolled to undergo SMILE as an alternative to Laser assisted keratomileusis (LASIK). all underwent preoperative and postoperative topography, wavefront examinations and cycloplegic refraction. All patients had an refractive error in the range from -1.75 to -10.25 with astigmatism from -.5 to -2.75. Tear film parameters including tear osmolality and corneal hysteresis were also determined.

Results:

52 patients were enrolled and underwent uneventful surgery. At month 1 all achieved uncorrected vision of 20/25 or better. The mean preoperative BCVA was 20/20 and the mean UCVA at month 1 was 20/18 and BCVA 20/15. No patient lost a line of BCVA. The mean preoperative refractive error was a spherical equivalent of -6.55 and postoperatively -0.15 at month 1. Tear osmolality preoperatively was a mean of 308 and postoperatively 318. There was no significant difference in the ORA/corneal hysteresis values pre- and postoperatively.

Conclusions:

SMILE appears to result in predictable and safe refractive outcomes with minimal impact on ocular surface hydration and biomechanical safety in the initial commercial pilot of its use in North America.
