AIM: To prospectively study the success rate and complications of viscocanalostomy, a non-penetrating glaucoma surgery. METHODS: Prospective non-randomized consecutive case series of 57 eyes (57 patients) with medically uncontrolled primary and secondary open-angle glaucoma. Viscocanalostomy was performed on all participants with injection of viscoelastic into the surgically created ostia of Schlemm's canal as well as into the scleral bed, the superficial scleral flap was loosely sutured. Intraocular pressure (IOP), visual acuity, and number of goniopunctures were measured. RESULTS: The mean follow up period was 34.1 months. The mean preoperative IOP was 24.6 mmHg; while the mean postoperative IOP was 5.6 mmHg at day 1 and 13.9 mmHg at 36 months. Ninety percent of patients achieved IOP below 21 mmHg with or without medication at 60 months, complete success rate (IOP < 21 mmHg without medication) was 60% at 60 months. Twenty-one patients (37%) needed Nd:YAG goniopuncture postoperatively to control raised IOP, mean time for goniopuncture application was 9.4 months, mean pre-goniopuncture IOP was 20.4 mmHg and mean postgoniopuncture IOP was 12.6 mmHg (p < 0.0001). CONCLUSION: Viscocanalostomy appears to be a promising modification of filtering surgery.
