AIM: To investigatethe clinical effects of phacoemulsification and intraocular lens implantation for high myopia combined with cataract.

METHODS:Selected from January 2012 to December 2013, 82 patients(96 eyes)with high myopia combined with cataract in our hospital as study group. The patients were divided into control group and study group randomly. There were 40 patients(46 eyes)in control group. There were 42 patients(50 eyes)in study group. The patients in control group were treated with small incision extracapsular cataract extraction and intraocular lens implantation. The patients in study group were treated with phacoemulsification and intraocular lens implantation. The visual acuity, best-corrected visual acuity and complications of corneal edema, posterior capsule opacification and increasing intraocular pressure of the patients in two groups were compared and analyzed. The patients' fundus stations were checked in study group after surgery.

RESULTS: Compared with control group, the patients in study group after treatment, the ratio of uncorrected visual acuity from 0.1 to 0.5, 0.5 to 1.0, 1.0 to 1.5 were increased significantly. There was no statistically significant(P<0.05). Compared with control group, the patients in study group after treatment, the ratio of best-corrected visual acuity from 0.1 to 0.5 was decreased significantly, only 28%, and the ratio of best-corrected visual acuity from 0.5 to 1.0 and 1.0 to 1.5 were increased significantly, up to 58% and 14%, there was statistically significant(P<0.05). Compared with control group, the patients in study group the incidence of complications of corneal edema, posterior capsule opacification and intraocular pressure were decreased, and the incidence of corneal edema was increased significantly, there was statistically significant(P<0.05).

CONCLUSION:Phacoemulsification and intraocular lens implantation has positively significant for improving best-corrected visual acuity effectively and reducing complications of the patients with high myopia combined with cataract.
