Purpose: To evaluate quality of life (QoL) with a new questionnaire after canaloplasty (CP) and trabeculectomy (TE).
Patients and methods: We assessed outcomes of surgery, rate of revision surgeries, patients’ mood, and influence of postoperative care on QoL, surgery interference with daily activities, and postsurgical complaints. Patients completed the QoL questionnaire 24 months after surgery.
Results: Patients who underwent CP (n=175) were compared to TE patients (n=152). In the CP group, 57% of patients expressed high satisfaction, while 41% of patients in the TE group said they were highly satisfied. The satisfaction difference was statistically significant (P=0.034). Significantly fewer second surgeries were needed after CP (8% CP versus 35% TE, P<0.001). Patients were more positive in the CP group (54% CP versus 37% TE, P<0.009). Stress related to postoperative care was lower in the CP group compared to the TE group (14% versus 46%). Difficulties with activities of daily living, such as reading, were much lower or even nonexistent after CP, and complaints like eye burning or stinging were significantly lower in the CP group.
Conclusions: Compared with TE, CP is associated with less QoL impairment and higher patient satisfaction after surgery. However, long-term data on intraocular pressure reduction after surgery are needed to confirm long-term patient satisfaction with this surgery.
