Customized Wavefront-Optimized Transepithelial Photorefractive Keratectomy for a Retained Lenticule Fragment After Primary SMILE

J Refract Surg. 2020 Jun 1;36(6):395-399. doi: 10.3928/1081597X-20200512-01.

Abstract

Purpose: To describe the surgical outcomes after transepithelial photorefractive keratectomy (PRK) for a case of retained intrastromal lenticule fragment after small incision lenticule extraction (SMILE).

Methods: Transepithelial PRK was performed to minimize corneal irregularity and to correct residual refractive errors in a patient who had undergone failed lenticule extraction, which resulted in a refractive lenticule fragment being retained for 14 months after primary SMILE.

Results: At the postoperative 6-month visit, uncorrected distance visual acuity and corrected distance visual acuity improved to 20/20 and 20/20, respectively, and corneal tomography depicted normalization of the corneal surface. Corneal higher order aberrations, including coma, trefoil, and spherical aberration, were markedly reduced.

Conclusions: Transepithelial PRK is a potential option for the management of a retained lenticule fragment after primary SMILE. [J Refract Surg. 2020;36(6):395-399.].
