Abstract Details

Purpose:

To evaluate ReLEx® SMILE technology for high myopia correction.

Setting:

1 - St.-Petersburg branch of Sv. Fyodorov “Eye Microsurgery Clinic”; 2 – North-Western State Medical University named after I.I. Mechnikov. St.-Petersburg, Russia.

Methods:

SMILE surgeries were performed in 64 eyes with high myopia (32 patients) with the VISUMAX system ('Carl Zeiss Meditec'). The age of all patients was 26,8±4,4 years. Follow-up period was up to 12 months. We used two different techniques for lenticule removal. The first one was the “pushing out”: the lenticule was dissected by using a special long flat spatula and pushed out through the opposite incision to the outside by using the same spatula. The second one is the “pulling out”: the lenticule was dissected by using single “Cobra” spatula and finally pushed out through the same incision.

Results:

The spherical equivalent (SE) of our high myopic group ranged from - 6,25 D to -14,75 D, and it was changed from – 7,86 D (± 2,13 D) prior to ReLEx® SMILE to - 0,38 D (± 0,49 D) 12 months later. The UCVA was changed from 0,03 (± 0,01) before surgery to 0,84 (± 0,23) to 12 months later. High order aberration coefficient was increased from 1,1 (± 0,6) before SMILE to 1,8 (± 0,4) 12 months later (PENTACAM system). As for complications there were only 2 small ruptures (3,1%) of the incision margin in cases where the thickness of the corneal pocket was 120 microns.

Conclusions:

ReLEx® SMILE technology is a sufficiently effective, safe and predictable operation for the correction of high myopia and myopic astigmatism.
