Purpose: To examine the efficacy, safety and retention rates of silicone punctal plugs for the treatment of dry eye disease and various ocular surface disorders. Patients and Methods: Medical records of patients who underwent universal size silicone punctal plug insertion from November 2019 to January 2021 were retrospectively reviewed. After plug insertion, all patients had 6 months or more of follow-up. The clinical data collected were the sex and age of the patients, indications for plug insertion, Symptomatic Improvement (SI), initial versus replacement plug, spontaneous extrusion or removal of the plug, and percentage of complications. Furthermore, changes in objective ocular surface parameters were analyzed using the Corneal Fluorescein Staining (CFS) score, Schirmer’s test and Tear break up time in plug-retaining patients at baseline and at six month follow-up. Plug retention rates were analyzed using Kaplan-Meier analyses. Results: Silicone punctal plug was inserted in 164 eyes of 86 patients (62 women and 24 men). All insertions were in the lower punctum. Primary keratoconjunctivitis sicca syndrome was the most common indication for punctal plug treatment (102 eyes, 62.2%), followed by post Lasik group, recurrent corneal erosion, exposure keratoconjunctivitis and Sjogren’s syndrome. The symptoms improved in 136 (83%) of 164 eyes at six month follow-up. The mean score of the fluorescein staining of the cornea was reduced from 2.9 ± 0.1 to 1.1 ± 0.1 with silicone punctal plug treatment at 6 ± 2 weeks follow-up and 0.6 ± 0.1 at 6 month follow up. The spontaneous total extrusion of silicone punctal plug occurred in 6 eyes (3.6%). The plug was removed in 9 eyes (5.5%) because of discomfort(8 eyes) and canaliculitis in one eye. Conclusions: Punctal plug insertion is a simple, effective, safe and reversible method to treat aqueous tear deficiency and other ocular surface diseases. Complications were rare. Discomfort was the commonest reason for removal apart from a single case of infective canaliculitis. Universal size fits majority of patients with good tolerance. However, spontaneous plug loss occurs in a significant minority of patients.
