Clinical effect of small incision phacoemulsification combined with trabeculectomy in tunnel in the treatment of glaucoma with cataract

Objective To explore the clinical effect of small incision phacoemulsification combined with trabeculectomy in tunnel in the treatment of glaucoma with cataract.Methods Thirty-six cases(38 eyes)who performed 2.8 mm small incision phacoemulsification combined with trabeculectomy in tunnel were enrolled in this study.The visual acuity,intraocular pressure(IOP),astigmatism and complications were assessed before and after operation.Results The visual acuity ≥ 0.4 was in 29 eyes(76.32％)postoperatively.After followed up 3-6 months,the IOP of all the patients had been effectively controlled.The IOP at 1 week[(12.24 ± 3.59)mm Hg(1 mm Hg =0.133 kPa)]and 3-6 months[(15.53 ± 5.26)mm Hg]after operation was significantly lower compared with before operation[(36.72 ± 4.34)mm Hg](P ＜ 0.05).There was no significant difference in astigmatism among before operation,1 month and 3-6 months after operation(P ＞ 0.05).Conclusion Small incision phacoemulsification combined with trabeculectomy in tunnel is an effective surgery for glaucoma with cataract,which can improve visual acuity and IOP.
