Abstract

Background

This prospective study focused on the results of a novel method for refractive correction, femtosecond lenticule extraction (ReLEx®) in hyperopia, and reports the first 47 eyes.

Methods

In 47 hyperopic eyes (26 patients), both a flap and a lenticule of intrastromal corneal tissue were simultaneously cut utilizing the Carl Zeiss Meditec AG (CZM) 200 kHz VisuMax® femtosecond laser system. Thereafter, the lenticule was manually removed and the flap repositioned. Forty two out of 47 hyperopic eyes of the treatment group completed the final 9-month follow-up. The patients mean age was 42.3 (±9.0) years. Their mean preoperative spherical equivalent (SE) was +2.8 (±1.3) D. UCVA and BSCVA after 9 months, objective and manifest refraction, as well as slit-lamp examination and side-effects were evaluated.

Results

Nine months postoperatively, 64 % of eyes treated were within ±1.0 D, and 38 % of eyes within ±0.5 D of intended correction. One of 47 eyes (2.1 %) lost more than 2 Snellen lines; none of the eyes had a UCVA less than 0.5. However, stability was less impressive when compared to ReLEx® for the correction of myopia.

Conclusions

First data suggest that ReLEx® is a feasible and effective procedure for treatment of hyperopia. Further research is needed to improve predictability and effectiveness of the procedure for the correction of hyperopia.
