Post-Laser In Situ Keratomileusis Epithelial Ingrowth: Treatment, Recurrence, and Long-Term Results.

Abstract

To study outcomes after surgical removal of epithelial ingrowth (EI) in post-laser in situ keratomileusis patients, specifically comparing visual results and recurrence rates between 2 different EI management techniques. In this retrospective chart review of 67 eyes of 54 patients who underwent surgical treatment for EI after laser in situ keratomileusis between July 1999 and July 2014 at the Bascom Palmer Eye Institute, Miami, FL, surgical techniques, recurrence rates, visual acuity (VA), and refractive error were assessed. Of the 67 eyes, 56 eyes (83.6%) had flap lift + scraping alone, and 11 eyes (16.4%) had flap lift + scraping + suturing. After mean follow-up of 2.5 years, 11 of 56 eyes (19.6%) treated with flap lift + scraping alone had EI recurrence, whereas no eyes treated with flap lift + scraping + suturing had EI recurrence. VA results and refractive errors were better in eyes treated with lift + scraping alone compared with lift + scraping + suturing at 1 month. In the 67 eyes with 1-year follow-up, VA and refractive errors improved from preoperative values and were comparable between groups. Scraping alone provides significantly better initial visual outcomes but higher EI recurrence rates compared with scrape-suturing. Long-term visual outcomes are comparable between 2 techniques.
