Abstract Details


To evaluate the visual and refractive outcomes, as well as the reproducability of Small Incision Lenticule Extraction (SMILE) in post- keratoplasty eyes.


Roayah Vision Correction Center, Alexandria, Egypt.


SMILE procedure was performed for patients with previous keratoplasty. The preoperative refractive errors, UCVA and BCVA were recorded. The residual refractive error, UCVA and BCVA were recorded 6 months postoperatively. The cap and lenticule diameters were calculated taking into consideration the graft diameter. The other parameters used were based on the degree of refractive error and central graft thickness.


8 eyes of 8 patients underwent SMILE procedure. Mean follow up was 6 months (range 5-7 months). The mean UCVA (Snellen decimal) changed from 0.14 (range, 0.05-0.3) preoperatively to 0.68 (range, 0.4-0.8) postoperatively. 3 eyes reached 0.8 UCVA postoperatively, 3 eyes reached 0.7, 1 eye reached 0.6 and 1 eye reached 0.4. The mean BCVA changed from 0.73 (range, 0.5-0.9) preoperatively to (range, 0.6-0.9) 0.8 at 6 months postoperatively. There was no loss of lines of UCVA nor BCVA in any of our patients by 6 months postoperatively. 1 eye encountered a full-thickness buttonhole intraoperatively.


SMILE procedure for the correction of post-keratoplasty myopia and astigmatism is a reproducible procedure with good visual outcomes.
