Estimation of risk-benefit ratio and comparison of post-operative efficacy results between trabeculectomy and canaloplasty.

The trabeculectomy group showed better results in terms of absolute success rate. However, canaloplasty may provide a better risk-benefit ratio in terms of qualified success rate, hospitalization time, and required post-operative interventions, since canaloplasty yielded equal or superior results compared to trabeculectomy.
