Abstract
Purpose
To investigate the long-term decentration changes and associated factors after SMILE surgery for high and low-to-moderate myopia.
Methods
47 eyes of 30 patients undergoing SMILE surgery at the Eye & ENT Hospital of Fudan University were included in this prospective study (age at surgery: 28.23 ± 7.38 years old, male:female = 13:17). 20 eyes of 15 patients were divided into low-to-moderate myopia (LMM) group, and 27 eyes of 20 patients to high myopia (HM) group by preoperative refraction. Main outcome measures included visual acuity, preoperative refraction, intraocular pressure, axial length, optical zone diameter, decentration, and ablation depth. Follow-up time was 11.50 ± 1.52 years (10 to 13 years).
