. Purpose:  To assess the effect of overnight wear of a contact lens‐based sensor (CLS) for monitoring of 24‐hr intraocular pressure (IOP) fluctuations on central corneal thickness (CCT). Materials and Methods:  Changes in the CCT, mid‐peripheral corneal thickness and central corneal radius (CCR) during overnight CLS wear in 20 eligible patients with ocular hypertension or established glaucoma were prospectively studied using ultrasound pachymetry and topography. Corneal thickness and CCR changes were evaluated from pre‐to‐postsleep, with the fellow eye as control. Paired t‐test or Wilcoxon signed‐rank test was used as appropriate and with α = 0.05. Relationship between the IOP profile recorded by the CLS and the pre‐to‐postsleep corneal thickness differences was assessed using the Spearman correlation coefficient. Results:  After CLS wear, mean CCT had changed from 523 to 537 μm (p = 0.015) in the study eye and from 518 to 522 (p = 0.206) in the fellow eye (n = 15). There was no difference in CCT change between eyes (p = 0.075). There were no statistically significant changes in horizontal or vertical CCR in either eye (p > 0.05 for all). No correlation was found between the pre‐to‐postsleep differences in the CLS signal and the pre‐to‐postsleep differences in ultrasound CCT measurements (p = 0.974). Conclusion:  The continuous IOP monitoring does not appear to be affected by differences in corneal thickness that occur during overnight CLS wear, although the CLS did induce some corneal swelling. This effect was not statistically significantly different from the control eye and does not seem to influence the CLS IOP profile.

The retirement home residents that we examined were not receiving adequate ophthalmological care; in particular, some of them had irreversible eye diseases that were not being treated. The ophthalmological care of retirement home residents needs to be improved through better collaboration of all types of personnel taking care of them.

PurposeTo evaluate quality of life (QoL) with a new questionnaire after canaloplasty (CP) and trabeculectomy (TE).Patients and methodsWe 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.ResultsPatients 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.ConclusionsCompared 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.

Canaloplasty and trabeculectomy are safe and effective procedures in the treatment of open-angle glaucoma. Both surgical methods reduce the IOP and the postoperative medication to a statistically significant extent. Trabeculectomy attains higher long-term complete success rates accompanied by slightly increased early postoperative complication rates (n. s.), compared to canaloplasty.
