Small Incision Lenticule Extraction (SMILE) as Re-treatment for a Thick LASIK Flap.

Purpose To report the case of a residual refractive error after LASIK for moderate myopia successfully re-treated several years later using the small incision lenticule extraction (SMILE) technique. Methods Case report. Results Following LASIK, the patient showed a central flap thickness of 269 microns, whereas residual stromal bed thickness under the flap was 210 microns. SMILE was performed within the flap. In this less invasive surgical procedure, the residual stromal bed is not manipulated and ablation is conducted on the existing flap. At 6 months of follow-up, visual and anatomical outcomes were satisfactory. Uncorrected distance visual acuity was 20/20 and refractive error was +0.75 -0.50 × 30°. Conclusions In selected patients with a thick flap and thin residual stromal bed after LASIK, SMILE as re-treatment may be a good option. [J Refract Surg. 2016;32(10):718-720.].
