·AIM:To research the treatment effects of internal double incisions phacoemulsification and trabeculectomy for glaucoma combined with cataract.METHODS:All of 35 cases 46 eyes diagnosed with glaucoma combined with cataract were treated.Phacoemulsification,intraocular lens(IOL)implantation and trabeculectomy were performed simultaneously using the same main incision and two different internal incisions.The follow-up time was from 1 to 6 months postoperatively.RESULTS:The mean intraocular pressure(IOP)preoperatively was 38.3(25-69)mmHg.Postoperatively the mean IOP was 15.6(8-28)mmHg.The range of preoperative vision was from light perception to 0.5.The postoperative best-corrected visual acuity(BCVA)was 0.02-1.0,including ≥0.5 in 21 eyes,≥0.3 in 34 eyes.CONCLUSION:Phacoemulsification,IOL implantation and trabeculectomy performed simultaneously using the same main incision and two different internal incisions can reduce the interaction and make use of incision effectively.It is safe and effective.
