Analysis of the clinical effects of the two-site incision combined phacoemulsification and trabeculec- tomy for patients with glaucoma and cataract

Objective To evaluate the clinical effects of the two-site incision combined surgery of phacoemulsification, foldable intraocular lens implantation and trabeculectomy for patients with glaucoma and cataract. Methods Retrospectively analyzed pre- and post-operation effects of visual acuity, intraocular pressure and filtering bleb morphology and complications. Thirty five eyes of 32 patients with glaucoma and cataract underwent the combined operations. Results All cases were followed up for 12 to 48 months. Intraocular pressure of 32 eyes was controlled under 21mmHg （1mmHg = 0. 133kPa） and 20 eyes lower than 15mmHg. The average intraocular pressure was from （28.16 ± 2.63 ）mmHg pre-operation to （ 16.32 ± 3.45）mmHg post-operation （t =21.60, P 〈0. 05）. The species of anti-glaucoma drugs from preoperative average of 2.59 ± 0.49 was decreased to only one kind in three patients postoperative. Postoperative visual acuity of 30 eyes （85.7%） was increased. The major complications were a transient corneal edema and iridocyclitis. Conclusions Combined phacoemulsification, foldable intraocular lens implantation and trabeculectomy in the treatment of glaucoma and cataract patients can control intraocular pressure and improve visual acuity.
