RESUMO
In this article, the authors attempt to determine the retention rate and benefits of Painless Punctal Plug F(TM) placed in patients diagnosed with dry eye. This is a prospective, observational cohort study. Forty patients diagnosed with dry eye underwent Painless Punctal Plug F placement in the inferior puncta (80 puncta) in a private clinic from January 2010 to July 2012. Patients were then followed up monthly for seven months taking note of plug retention, spontaneous plug loss, and complications. Retention rates of patients with mean age of 58.6 years were 100% after one month, 98.75% after two months, 96.25% after three months, 95% after four months, 93.75% after five months, and 92.5% after seven months. In the 80 plugs, three plugs underwent spontaneous punctal plug loss and three plugs were removed due to local discomfort. In total, 74 out of 80 plugs remained intact after seven months of follow-up. Kaplan-Meier analysis showed that there was propensity for spontaneous punctal plug loss or plug removal in the Sjogren group as compared to the non-Sjogren group. No complications were noted such as epiphora, local inflammatory reaction, nor canalicular pyogenic granuloma except for local discomfort. This study showed that Painless Punctal Plug F has a high retention rate with the following benefits, it has one-size, fitted for small to medium puncta; extended round end which made prior dilation unnecessary and once inserted, the soft round bulb fits snugly inside the punctum preventing plug loss.
