Abstract:AIM: To compare the effects of one-site vs two-site phacotrabeculectomy, intraocular lens implantation with trabeculectomy in the treatment of glaucoma with cataract.
METHODS: This prospective, randomized study including 60 patients(78 eyes)with glaucoma and cataract. One-site approach was performed in 31 patients(40 eyes)and two-site approach in 29 patients(38 eyes). Visual acuity, intraocular pressure(IOP), filtration, astigmatism and complications were observed at 2wk and 1mo after operation.
RESULTS: Postoperative visual acuitywas improved in 78 eyes. There was no significant difference of visual acuity between two groups at 2wk and 1mo after operation(P>0.05). The IOP at 2wk and 1mo after operation were lower than that of preoperation in two groups(P<0.05), and there was no significant difference between two groups(P>0.05). The number of eyes with functional filtration has no significant difference between two groups at 2wk and 1mo after operation(P>0.05); 2wk after operation, the astigmatism in one-site approach was bigger than preoperative astigmatism, also bigger than that of two-site approach(P<0.05), and there was no significant difference of astigmatism between two groups at 1mo after operation(P>0.05). There were 3 cases with few hemorrhage in anterior chamber after operation, 12 cases with slight corneal epithelial edema, descemet membrane folds, 6 cases with cellulose exudation in anterior chamber.
CONCLUSION: It is an ideal operation that two-site approachphacoemulsification and intraocular lens implantation combined with trabeculectomy in cataract and glaucoma patients, and has the advantages of simple operation, good treatment effect.
