NEW ORLEANS — Patient- and surgery-related parameters had a minimal effect on the safety, efficacy and predictability of small-incision lenticule extraction for myopia, according to a study presented here.

Jesper Hjortdal, MD, presented results during the Journal of Refractive Surgery’s Hot, Hotter and Hottest: Late Breaking News session on Refractive Subspecialty Day preceding the American Academy of Ophthalmology meeting.

Hjortdal’s presentation was based on a paper that was awarded the Journal of Refractive Surgery’s annual Waring Medal.

“We can say that safety and efficacy were, from a clinical perspective, found to be independent of spherical treatment attempts up to 10 D of myopia and were not influenced in any degree by the age of the patients,” Hjortdal said. “In terms of predictability, I think we can conclude that the treatment nomogram needs only minor adjustments.”

The prospective clinical quality control study included 670 eyes of 335 patients with up to 10 D of myopia and up to 2 D of astigmatism who underwent the ReLEx smile procedure (Carl Zeiss Meditec) and were followed for 3 months.

Results showed that spherical equivalent refraction was within 1 D of targeted values in 93% of eyes and within 0.5 D in 70%. Mean undercorrection was 0.25 D. Undercorrection was predicted by increasing age and steeper corneal curvature. However, these factors had a minimal effect , Hjortdal said.

Visual acuity of 20/25 or better was attained in 85% of eyes targeted for emmetropia.

Four percent of eyes gained two or more lines of vision, and 1.5% lost two or more lines at 3 months.
