Abstract
PURPOSE
To assess the association of time since primary laser-assisted in situ keratomileusis with flap relift success and risk of epithelial ingrowth in eyes undergoing flap relift after primary laser-assisted in situ keratomileusis.
SETTING
Hong Kong Sanatorium & Hospital, Hong Kong Special Administrative Region.
DESIGN
Retrospective, observational case series.
METHODS
Seventy-three eyes with flaps relifted for refractive enhancement laser-assisted in situ keratomileusis were included. Main outcome measures included rate of relift success and epithelial ingrowth; associations of time since primary laser-assisted in situ keratomileusis, sex, age at relift, year of relift, and flap creation method in primary laser-assisted in situ keratomileusis with relift success and epithelial ingrowth.
RESULTS
Relifting was successful in 71 eyes (97.3%). Among the successfully relifted eyes, 12 (16.9%) developed epithelial ingrowth, of which 3 (4.2%) were clinically significant. No eyes lost more than one line of corrected distance visual acuity. The time since primary laser-assisted in situ keratomileusis (up to 22 years), sex, age at relift, year of relift, and flap creation method in primary laser-assisted in situ keratomileusis were not associated with relift success or epithelial ingrowth.
CONCLUSIONS
With our described surgical technique, flaps could be successfully relifted without much difficulty up to 22 years after primary laser-assisted in situ keratomileusis with a low incidence of epithelial ingrowth.
