AIM:To investigate the clinical efficacy of phacoemulsification combined with goniosynechialysis and only phacoemulsification on coexisted cataract after peripheral iridectomy.

METHODS:A total of 69 patients(85 eyes)with coexisted cataract after peripheral iridectomy were divided into two groups by drawing lots method. The patients in observation group(38 cases,45 eyes)were treated with phacoemulsification and IOL implantation, combined with goniosynechialysis, and the control group(31 cases,40 eyes)with phacoemulsification and IOL implantation. The follow-up time lasted 12mo. The intraocular pressure(IOP), best corrected visual acuity(BCVA), central anterior chamber depth and the change of anterior chamber angle of two groups before and after operations were compared and analyzed.

RESULTS:After 1wk, the postoperative mean IOP of observation group was 10.36±2.85mmHg,that of control group was 12.09±3.75mmHg, decreased significantly compared with preoperative(P<0.01). There was significant difference of that between two groups(t=2.41,P<0.05). The postoperative mean visual acuity of observation group and control group were 0.52±0.22 and 0.55±0.20 respectively,increased significantly compared with preoperative(P<0.01),and no significant difference between two groups(t=0.65,P>0.05). The postoperative mean central chamber thickness of observation group and control group were 3.57±0.32mm and 3.44±0.35mm respectively,increased significantly compared with preoperative(P<0.01), and no significant difference between two groups(t=1.79,P>0.05). Two months after the operation, there were 42eyes(93.33%)with adhesion range of anterior chamber angle was <90°in observation group, more than that in control group 31eyes(77.50%), the difference was significant(P<0.05).

CONCLUTION:The treatment method of phacoemulsification combined with goniosynechialysis for coexisted cataract after peripheral iridectomy can effectively open the adhesions of chamber angular, control the IOP and improve visul acuity and is safe.
