Clinical effects of accommodative training after laser in situ keratomileusis

Objective To observe the clinical efficacy of accommodative training on asthenopia after Laser in situ keratomileusis (LASIK). Methods Twenty-eight patients with asthenopia 3months after LASIK (from 34 to 45 years old) were enrolled.Accommodative facility training was performed 2 times a day,every 15 minutes by ±1.0D or ±2.0D flip lenses.Fifteen days were a course and 2 courses were suggested.The asthenopia score and accommodative facility before and after treatment were measured. Results The asthenopia score of patients after LASIK were 10.04±0.22 before treatment and 4.00±0.15 after treatment.There was a significantly decreased (P ＜0.05).The accommodative facility training were 5.27±1.22cpm (cycles per minute) before treatment and 8.98±1.69cpm after treatment.There was a statistically significant different (P ＜0.05) and the accommodative facility training after treatment were improved. Contusions The accommodative facility training is a simple and effective training on accommodative and binocular dysfunctions,which alleviate asthenopic symptoms after LASIK.
