AIM:To observe the effects of double incision combined surgery of single-stab trabeculectomy and phacoemulsification.

METHODS: Totally 28 cases(30 eyes)with glaucoma and cataract undertook the modified combined surgery of single-stab trabeculectomy and phacoemulsification. After traditional phacoemulsification, cut the bulbar conjunctiva and Tenons capsule from the 11 o'clock to 1 o'clock, then puncture into the anterior chamber in 2mm behind the corneal limbus with 3mm tunnel knife, shaping a 3mm wide, 1/3-1/4 thickness scleral tunnel. Getting into the trabecular tunnel, bite off 3 pieces of trabecular tissue about 1mm×1mm size. The changes in the imtraocular pressure(IOP)and the visual acuity before and after the surgery as well as filtering bleb(OCT confirmed)and complications were carefully observed in 3-6mo postoperatively.

RESULTS: The postoperative visual acuity in 1wk postoperatively less than 0.1 was found in 3 eyes, from 0.1 to 0.3 was found in 6 eyes,from 0.3 to 0.6 in 13 eyes,from 0.6 to 0.8 in 8 eyes.One eye had malignant glaucoma, and 8 eyes had cornea edema and slightly fibrin exudation in the pupil area; In all cases maintained function conjunctival blebs of filtering, OCT confirmed this.IOP remained normal in 28 eyes in 3-6mo follow up, IOP of 2 other eyes could be controlled by anti-glaucoma eye drops.

CONCLUSION:Double incision combined surgery of single-stab trabeculectomy and phacoemulsification is effective and safe,reduces the postoperative complications and is worthy of promotion.
