RESUMO
Purpose: The objective of this study was to assess the quality of outcomes of mini-Monoka stent dilatation for punctal stenosis using the lacrimal symptom (Lac-Q) questionnaire. Methods: Prospective interventional case series of 45 eyes of 25 consecutive patients who underwent mini-Monoka stent dilatation for primary punctal stenosis were included in the study. The stents were extubated at 4 weeks. The Lac-Q questionnaire was administered preoperatively and at 12 weeks and 24 weeks following the intervention. Outcomes assessed were anatomical success, functional success, and changes in the questionnaire scores including total, social impact, and lacrimal symptom scores. Statistical analysis was performed using the Wilcoxon signed-rank test, and the probability of obtaining a certain score was calculated using the multinomial log-linear model. P < 0.05 was considered as significant. Results: Monoka stents were performed for 45 eyes. A total of 75 questionnaire responses were analyzed. At the last follow-up of 24 weeks, the anatomical and functional success rates were 93.3% (42/45). The changes in the mean total score (7.68 preoperatively to 0.82 at 24-week follow-up) were statistically significant (P ? 0.001). The mean social impact scores showed significant improvement postoperatively from 4.06 to 0.53 (P ? 0.001). The mean lacrimal symptom score changed from a preoperative value of 3.62 to 0.28 (P ? 0.001) at the last follow-up. Postoperative scoring correlated well with the anatomical and functional success rates. The symptom scores corroborated with changes in the clinical outcomes. Conclusion: Mini-Monoka stent dilatation is a very effective intervention for the management of primary punctal stenosis, and Lac-Q questionnaire is a simple and useful tool to evaluate the quality of outcomes in such cases.
