AIM: To study the methods and effect of aphakia eye secondary posterior chamber intraocular lens(IOL)implantation with suture fixation under anterior chamber irrigation after vitrectomy.

METHODS: Thirty aphakia eyes underwent secondary posterior chamber IOL implantation with suture fixation under anterior chamber irrigation after vitrectomy. All the cases were followed up for 1.5 years.

RESULTS: Thrity cases(30 eyes)underwent posterior chamber IOL implantation successfully. The complications included hemorrhage of the ciliary body(1 case)in the operation and vitreous hemorrhage(1 case)and choroid detachment(2 cases)after the operation. The visual acuity of all cases was more improved than before, 24 cases(80%)had obtained post-operative visual acuity ≥0.3, of these, 8 cases(27%)≥0.5; 6 cases(20%)<0.3, of these, 2 cases(7%)<0.1.

CONCLUSION: The method of anterior chamber irrigation is safe and successful which can obtain stableintraocular pressure during and after the operation and lower complications. The operation is an effective method for improving the visual acuity after vitrectomy.
