[Clinical observation of combined surgery for cataract and glaucoma: phacoemulsification and viscocanalostomy].
OBJECTIVE
To evaluate the therapeutic effects and safety of phacoemulsification-intraocular lens (IOL) implantation combined with viscocanalostomy (V-P) and compared the outcomes of phacoemulsification-IOL implantation combined with trabeculectomy (T-P).


METHODS
Combined phacoemulsification with corneal incision, foldable intraocular lens implantation and viscocanalostomy was performed in 30 eyes of 28 cataract patients with primary open-angle glaucoma.


RESULTS
Follow-up was performed up to 6 months after surgery. The mean intraocular pressure (IOP) of V-P group was (14.65 +/- 2.70) mm Hg (1 mm Hg = 0.133 kPa) with a mean pressure reduction of 10.33 mm Hg compared with IOP before the operation (P = 0.000). There were no statistical differences of the IOP within two groups during postoperative 1 week, 1 and 6 month (P = 0.661, 0.381, 0.526). Postoperatively, the best corrected visual acuities of V-P group were > or = 0.5 in 18 eyes (follow-up 29 eyes, 62.1%), 20 eyes (28 eyes, 71.4%), 24 eyes (30 eyes, 80.0%) at 1 week, 1 month and 6 months, but no statistical difference with T-P group, (P = 0.621, 0.702, 0.893). Complications of V-P group included: Descemet's membrane puncture 2 eyes (6.7%), Schlemm's tube puncture 2 eyes (6.7%) and IOP spikes 4 eyes (13.3% at 24 hours postoperatively). The V-P group showed a significantly less inflammation, hyphema and choroidal detachment than that in the T-P group.


CONCLUSIONS
Phacoemulsification-IOL implantation combined with viscocanalostomy is a safe and efficacious surgery with lower complications.
