·AIM:To evaluate the effect of high myopia phacoemulsification and intraocular lens implantation.·METHODS:Totally 145 patients(56 cases of transparent crystal,89 cases of cataract),average age was 55 years old;preoperative visual acuity <0.1 in 139 cases,0.1-0.3 in 6 cases;corrected visual acuity <0.1 in 21 cases,0.1-0.3 in 42 cases,0.3-0.5 in 47 cases,≥0.5 in 35 cases.After local anesthesia,phacoemulsification with posterior chamber intraocular lens implantation was performed in all cases.·RESULTS:Posterior capsule rupture of intraoperative were in 4 cases,and the complications included corneal edema in 19 cases;within 6 months after operation,retinal detachment was in 2 cases and after cataract in 3 cases;3 months after operation,visual acuity <0.1 was in 9 cases,0.1-0.3 in 49 cases,0.3-0.5 in 40 cases,≥0.5 in 47 cases;and the corrected visual acuity of 0.1-0.3 was in 28 cases,0.3-0.5 in 38 cases,≥0.5 in 79 cases.·CONCLUSION:Phacoemulsification combined with intraocular lens implantation has the faster visual recovery,great safety and effect.Before surgery patients should be explained the difficulties of near vision,particularly for patients younger than 50 years olds and long-term near work.Meanwhile,the selection of patients should avoid patients with high degree mental stress.Moreover,patients should be informed with the increased likelihood of retinal detachment after operation.·
