Abstract Details

Purpose:

To investigate the long-term safety and stability of small incision lenticule extraction (SMILE) for moderate and high myopia.

Setting:

In recent years, SMILE has drawn much attention for the treatment of myopia in refractive surgery, therefore it is necessary to study on its long-term safety and stability.

Methods:

Retrospective observational case series. 42 eyes of 26 patients who underwent SMILE from May 2010 to March 2013 at the Fudan University Eye and ENT Hospital (Shanghai, China) were included. The preoperative medical records and postoperative month 1, year 1, years 5, years 7 visits were reviewed. The main outcome measures included uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), manifest refraction, Pentacam Scheimpflug imaging.

Results:

All surgeries were executed without any complications. At the final visit, LogMAR UCVA and BCVA were -0.093±0.074 and -0.12±0.066,respectively. A BCVA of 20/20 or better was achieved in 100% of eyes. Nineteen eyes (45%) showed no change in BCVA. 93% and 100% of eyes were within±0.5D and±1.00D of the target refraction. A regression of -0.17D was observed. However, no statistically significant difference was found in terms of mean corneal back curvature, posterior central elevation (PCE), subtracting preoperative PCE from postoperative PCE at various postoperative time points(P=0.077，P=0.185，P=0.196).

Conclusions:

SMILE was a safe and effective procedure for myopia, with good long-term safety and stability.
