Small-Incision Lenticule Extraction for Hyperopic Astigmatism
Purpose
To evaluate the visual and refractive outcomes, as well as the reproducibility of small incision lenticule extraction (SMILE) in hyperoic astigmatism.
Methods
SMILE procedure was performed for patients with hyperopic astigmatism. The preoperative refractive errors, UCVA and BCVA were recorded. The residual refractive error, UCVA, and BCVA were recorded up to 1 year postoperatively.
Results
Eyes of 8 patients underwent SMILE procedure. Mean follow-up was 4 months (range 2-6 months). The mean UCVA (Snellen decimal) changed from 0.14 (range, 0.05-0.3) preoperatively to 0.88 (range, 0.7-1) postoperatively. The mean BCVA changed from 0.73 (range, 0.5-0.9) preoperatively to (range, 0.6-0.9) 0.8 at last follow-up postoperatively. There was no loss of lines of UCVA nor BCVA in any of our patients postoperatively.
Conclusion
SMILE procedure for the correction of hyperopic astigmatism is a reproducible procedure with good visual outcomes yet it still need optimization and long-term follow-up is needed.
