AIM: To research surgery effect and complications of transscleral suture fixation intraocular lens(IOL)assisted with endoscope or with the traditional method.

METHODS: Thirty cases need IOL implantation without sufficient posterior lens capsule membrane support were chosen. These patients were divided into two groups randomly and every group had 15 patients. Group A underwent surgery of transscleral suture fixation IOL with the traditional method. Group B had surgery of transscleral suture fixation IOL assisted with endoscope. The surgical complications and postoperative effect were regularly observed and analyzed.

RESULTS: All patients were successfully completed surgery. The mean naked visual acuity(NVA)of group A was 0.26±0.14(from 0.1 to 0.6)one month after operation. The mean NVA of group B was 0.37±0.16(from 0.15 to 0.8). The postoperative NVA of two group patients was improved different degree than preoperative NVA. The differences of postoperative NVA between the two groups had statistical significance(t=2.351, P<0.05). The mean best-corrected visual acuity(BCVA)of group A and group B were 0.45±0.13(from 0.3 to 0.6)and 0.47±0.14(from 0.3 to 0.8)one month after operation. The differences of postoperative BCVA between the two groups had statistical significance(t=1.327, P>0.05). Group A appeared more complications included 3 cases of corneal edema, 3 cases of uveitis, 4 cases of anterior chamber hemorrhage, 2 cases of vitreous hemorrhage, 3 cases of IOL deviation or tilted, 1 case of the peripheral iris anterior adhesion, 2 cases of elevated intraocular pressure. Group B appeared only a few minor complications including 5 cases of corneal edema, 2 cases of uveitis.

CONCLUSION: With the help of endoscope for transscleral suture fixation IOL can ensure sutures fixed position is located in the ciliary sulcus, surgery complications decrease significantly and surgical effect is better compared with the traditional method.
