AIM:To observe the practical effect of anesthesia under tenon capsule in the temporal scleral manual small incision cataract surgery after trabeculectomy.METHODS:Twenty-nine patients(32 eyes) were treated by anesthesia under tenon capsule in the temporal scleral manual small incision cataract surgery after trabeculectomy,the anesthesia effect in operation,postoperative vision,postoperative intraocular pressure(IOP) and complications after the operation were observed.RESULTS:Twenty-nine eyes(90.6%) were complete and pain free,3 eyes(9.4%) had mild pain.All patients got improved vision and maintained functional filtering bleb effectively.In 3-12months’ follow-up after the operation,IOP were under control well.The main complications were corneal edema,anterior chamber exudates and quickly increasing IOP after operation.CONCLUSION:Using anesthesia under tenon capsule in the temporal scleral manual small incision cataract surgery after trabeculectomy is safe,effective and economic.It can improve the vision,meanwhile,maintain the functional filtering bleb.
