Abstract:
Objective To explore the relationship between age and refractive predictability of excimer laser in situ keratomileusis (LASIK)for the correction of myopia.Design Retrospective case series.Participants 362 patients(703 eyes)who had performed LASIK.Methods According to the age,patients were divided into four groups(≤30y,31～34y,35～39y and≥40y).Their preoperative and postoperative refractive powers examined with automatic refactor as well as manifest optometry were analysed and followed up from 6 months to 2 years.According to pre-operative refractive power,patietns were divided into low and moderate myopia group(≤-6.00D), high myopia group(-6.25～-12.00D)and super-high myopia group(≥-12.25D).The eyes with refractive power at post-operative 2 years≥-1.00D were regressive eyes.Main Outcome Measures Refractive error before surgery,intended residual refractive power and 3,6, 12, 24 months post-operative refractive powers.Results There were no significant differences between intended residual refractive powers and refractive powers at post-operative 6 month in 3 groups(
