AIM:To study the application value and therapeutic effect of small incision trabeculectomy in tunnel in cataract combined with glaucoma surgery.

METHODS:Eighty-two patients of ninety eyes with cataract combined with glaucoma were selected in our hospital from May 2013 to May 2015, all of them treatment of small incision trabeculectomy in tunnel surgery, compare the difference of intraocular pressure and refractive degree at different time points before and after operation; To analyze the improvement of visual acuity after surgery and the occurrence of complications.

RESULTS:The intraocular pressure of postoperative 1, 7d, 1 and 6mo(19.38±3.63, 12.96±2.84, 11.37±1.05, 11.89±0.82mmHg)were lower than preoperative(32.65±6.42mmHg), and the difference has statistical significance(P<0.05). The vertical corneal refraction first increased and then decreased after the operation. The difference time points were higher than the preoperative, the difference was statistically significant(P<0.05). The horizontal corneal refraction first decreased and then increased after surgery. The horizontal corneal refraction at each time point except 1mo after surgery and preoperative differences were statistically significant. Five eyes(6%)of patients with vision <0.1 after 6mo of operation, forty-eight eyes(53%)with vision 0.1-0.5, 29 eyes(32%)with vision 0.6-0.9, eight eyes(9%)with vision >1.0, the vision was significantly improved after 6mo of operation(P<0.05). There were 3 eyes of patients with anterior chamber, 5 eyes had corneal edema, 3 eyes had the appearance of anterior chamber, and recovered within 7d after treatment.

CONCLUSION:The small incision trabeculectomy in tunnel for cataract combined with glaucoma has significant curative effect, higher safety, and highly clinical value.
