[Observational study on the impact of corneal power on refractive status of patients after small incision lenticule extraction surgery].

Objective: To observe the change of refractive status and possible influencing factors for patients with different corneal power who underwent small incision lenticule extraction (SMILE) surgery. Methods: Prospective cohort study was performed for patients who underwent small incision lenticule extraction (SMILE) surgery at Daping Hospital and Research Institute of Surgery of Third Military Medical University between January and August 2016. The patients were divided into 3 groups according to their corneal power: low curvature group (K(1)≤41.00 D), common curvature group (41.00 D更多
