ABSTRACT
PURPOSE:
To compare the visual outcomes and incidence of complications of lifting with recutting the lamellar flap in laser in situ keratomileusis (LASIK) enhancement surgery.DESIGN:
Retrospective case-control study.PARTICIPANTS:
Two hundred twelve consecutive eyes undergoing a LASIK enhancement procedure at a single surgery location during a 5-year period.METHODS:
Charts of participants were obtained and outcome measures obtained. MAIN OUTCOMEMEASURES:
Uncorrected visual acuity, best-corrected visual acuity, refractive error, complications.RESULTS:
Relifting of flaps was performed in 164 of 212 eyes (77.4%), and recutting of flaps was performed in 48 of 212 eyes (22.6%). There were no significant differences in early visual outcomes between the two groups. At 1 year patients had significantly better uncorrected vision if the flap was lifted rather than recut (20/24.7 vs. 20/31.3, P < 0.008). In addition, the flap lift group had a significantly more stable refraction at 1 year than did the recut group (change in spherical equivalent +0.05 diopters (D) vs. -0.57 D). The incidence of complications did not significantly differ between the two groups.CONCLUSIONS:
LASIK enhancement surgery can be performed safely and effectively by either lifting or recutting a flap. Lifting the flap may show better long-term stability of refractive error and uncorrected acuity.
