Phacoemulsification and intraocular lens implantation combined goniosynechialysis for primary acute angle closure with cataract

Objective To study the clinical results of phacoemulsification and intraocular lens implantation combined goniosynechialysis for primary acute angle closure with cataract. Methods 28 eyes from 28 patients who suffered from primary acute angle closure with cataract had undergone phacoemulsification with foldable posterior chamber lens implantation combined goniosynechialysis through 3.2mm clear corneal incision and were retrospectively studied from Jan.2004 to Jun.2006.The patients were followed up at least 6 months,meanly 8.7 months. Results The IOP significantly decreased from a preoperative mean of(24.25±3.09) mmHg under medication therapy to a postoperative mean of(15.48±1.75) mmHg(t=3.175, P=0.04).The mean central anterior chamber depth was increased from (1.74±0.43) mm preoperatively to(3.19±0.04) mm postoperatively (t=-17.19,P=0.000).The angle of anterior chamber in all operated eyes have become wider and the parts of angle closure have opened in different degree.The leaving size of angle closure were ≤90 degree in all cases.The best corrected visual acuity was significantly improved in all cases. Conclusion Phacoemulsification and intraocular lens implantation combined with goniosynechialysis can be a good alternative way in treating primary acute angle closure with cataract.It could result in controlling of the IOP together with improvement of the visual acuity.
