简要总结
A prospective study included 20 patients with super high myopia who underwent bilateral uneventful cataract. 360°anterior capsule polishing was performed with double-ended capsule polisher randomly in one eye, and the opposite unpolished was used as the control. The refractive state and size of anterior opening were measured at postoperative 1 day as the baseline. Then they followed up at 1 month, 3 months and 6 months after surgery to record refractive state, higher-order aberrations, size of anterior opening, tilt and decentration of IOL (intraocular lenses)and PAD(postoperative aqueous depth). The paired t test was used to compare the differences between the two groups, and the same test the postoperative follow-up comparing with the baseline.
