PURPOSE: To assess the long-term efficacy and safety of hyperopic laser in situ keratomileusis (LASIK).
SETTING: Department of Ophthalmology, St. Thomas' Hospital, London, United Kingdom.
DESIGN: Prospective cohort study.
METHODS: Hyperopic LASIK was performed using a mechanical microkeratome, an optical zone of 6.5 mm, and a blend zone of 1.5 mm. Simple hyperopia was treated.
RESULTS: The mean patient age was 51.6 years (range 34 to 60 years). Preoperatively, the mean spherical equivalent (SE) was +3.74 diopters (D) (range +1.25 to +6.50 D). The mean attempted correction was +3.64 D (range +1.5 to +6.0 D). The mean follow-up was 16.5 years. The mean SE was +0.28 D (range -1.0 to +1.5 D) at 12 months, +0.84 D (range -0.75 to +3.35 D) at 5 years, and +1.74 D (range -0.75 to +4.13 D) at 16 years, representing an increase in hyperopia of +1.47 D ± 1.43 (SD) between 1 year and 16 years (P < .0001) and of +1.13 ± 0.8 D between 5 years and 16 years (P < .03). The uncorrected distance visual acuity improved at 16 years (P < .0001); corrected distance visual acuity (CDVA) was unchanged (P < .2). The efficacy index was 0.5 and the safety index, 1.09. One eye (3%) lost 2 lines of CDVA. Keratometry remained stable between 1 year and 16 years (P < 1.0). Four eyes (12%) had cataract surgery, and 2 (6%) had laser iridotomy. There was no ectasia.
CONCLUSIONS: After hyperopic LASIK, an increase in hyperopia occurred between 1 and 5 years and 16 years. At 16 years, efficacy was limited but with no sight-threatening complications.
