Abstract:
Objective To evaluate the clinical effect of phacoemulsification and low powered posterior chamber intraocular lens implantation in high myopia. Methods Phacoemulsification was performed on 128 eyes of 84 patients with cataract in high myopia through scleral tunnel incision. Average phaco time was 201s and ultrasonic energy was 33.8%. Results The visual acuity 0.4 or better on the first day, in the first week and first month after the operations was in 71.1%,75.8%,79.7%respectively. Three months after surgery, 22.6% reached the vision of 1.0. The main cause of the poor result is due to the pathologic changes of the fundus in high myopia. The major complications were corneal edema (4.3%), fibrinous exudate in anterior chamber (1.6%) and rupture of posterior capsule (2.3%). Conclusion Phacoemulsification and low powered posterior chamber intraocular lens implantation offers advantages of better rehabilitation of visual acuity, proper correction of ametropia, prevention of retinal detachment and is an unitable technique for highly myopia cataract patients.
