Simple surgical punctal occlusion with high frequency radiowave electrosurgery

Abstract Background To introduce and evaluate the efficacy of a simple punctal occlusion technique for dry eye patients. Methods Medical records of 79 eyes from 40 patients refractory to common dry eye conservative treatment who underwent multiple high-frequency radio-wave electro-punctal occlusion were retrospectively reviewed. Pre- and post-procedural ocular surface indices (Schirmer test, tear break-up time (TBUT), and corneal staining grade (Oxford scheme)) and subjective symptom scores (including frequency of artificial tear use, interval between procedures, and total repeat time) were analyzed. Results Average Schirmer test result was significantly (P
