The objective was to evaluate the results of Nd:YAG laser goniopuncture after viscocanalostomy and to investigate the rate of penetration in non-penetrating surgery. Results of viscocanalostomy and incidence of goniopuncture were retrospectively investigated in 33 eyes of 33 patients. Success was defined as an intraocular pressure (IOP) below 19 mmHg with an at least 30% decrease compared to the last preoperative measurement. General success rates after a mean follow-up of 33.5 ± 11.3 months were 79 and 46%, with and without medications, respectively. Mean IOP levels, which were 37.7 ± 9.9 mmHg at the diagnosis without treatment and 27.7 ± 11.3 mmHg at the last preoperative measurement with medical treatment, significantly decreased to 12.7 ± 4.8 mmHg at the last follow-up visit ( P
