Abstract Details


To compare outcomes of combine procedures: phaco-canaloplasty (PC) versus phaco- nonpenetrating deep sclerectomy (PNDS) with HealaFlow.


Ophthalmology Department, Military Institute of Medicine, Warsaw, Poland.


A randomized, prospective study. The study included eyes after PC (31 eyes) and PNDS (31 eyes). The indication was uncontrolled primary open angle glaucoma (POAG) and cataract. Best corrected visual acuity (BCVA), intraocular pressure (IOP), anterior and posterior segments of the eye, number of medications were examined. Follow-up examinations were done on days 1 and 7 and at 1, 3, 6, 12 months. Complete and qualified success was defined as an IOP ≤18 mmHg. For statistical analyses Mann-Whitney U test, Student’s t-test, analysis of variance were used; survival analysis was performed using the Kaplan-Meier method.


After 12-month follow-up, mean IOP decreased in the PC group from 18.9±6.9 to 12.4±2.8mmHg and in the PNDS group from 19.2±5.8 to 13.6±3.0 mmHg (p<0.05). In both groups preoperatively and postoperatively at 12-month follow-up there were no significant differences in IOP (p>0,05). There was no statistically significant difference between the number of medications used in either group (p>0.05). Complete success rates were 91.6 % and 89.0%, respectively (p=0.559) and qualified success rates were 100.0 % and 97.1%, respectively (p=0,961). The most frequent postoperative complication in PC was hyphema, which was observed in 58% of subjects. In PNDS postoperative care additional procedures where used, such as suturolysis, 5-FU subconjunctival injection, needling and goniopuncture.


Both PC and PNDS lead to an effective decrease in the IOP in short-term follow-up and demonstrate similar efficacy and safety. However, much higher quality of life in case of PC is to be emphasised.
