Examinations
Before surgery, all the enrolled patients were examined by slit lamp, IOP and corneal (ECC) were measured. All patients were taken refractive examination and the best corrected visual acuity (BCVA) was determined. Corneal curvature was determined by keratometer, and A and B ultrasonography were performed to determine the axial length of the eye. The SRK-T formula was used to calculate the IOL degree. Fundus photos were taken and optical coherence tomography (OCT) was used to examine fundus conditions. Follow-up visits were performed 1 week, 1 month, 3 months and 6 months after the operation, and all preoperative examinations were also performed to evaluate postoperative recovery and complications.
