Retention rates and benefits of Painless Punctal Plug F(TM) in dry eye patients.

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.

Use of an imaging device after nonablative radiofrequency (Pellevé): treatment of periorbital rhytids.

OBJECTIVE: To use the Canfield Reveal imager in objective photo documentation of the effect of nonablative radiofrequency (Pellevé) treatment on periorbital rhytids. METHODS: This is a prospective cohort study. Twelve patients underwent 1 to 2 sessions of nonablative radiofrequency (Pellevé) treatment over the periorbital region. INCLUSION CRITERIA: aged 30 to 60 years old, minimal tissue laxity, and shallow wrinkle development. Standardized reproducible photographs (left, frontal, right views) with use of the Canfield Reveal imager's superimposition feature were taken of each patient prior, immediately after application, and on 2nd, 4th, 6th, and 8th week follow up. Brow elevation was measured in the pre- and posttreatment photographs with the use of the Canfield Reveal imager and rendered the photographs in 3-dimensional images. RESULTS: Comparison of the pre- and posttreatment photographs taken via the Canfield Reveal imager showed reduction in the wrinkles, smoothening, and tightening of the eyelid and the periorbital tissue. Patients exhibited an average increase of 2.05 mm (p<0.001) of eyebrow lift and 0.98 mm (p<0.001) of superior eyelid crease elevation immediately after treatment. Eight weeks after, average brow elevation was measured at 3.52 mm (p<0.001) and crease elevation at 1.84 mm (p<0.001). The 3-dimensional imaging feature rendered in normal skin tone, and shades of gray showed softening of fine lines and crow's feet after treatment. Furthermore, it also rendered in color relief that highlighted the changes seen with depressions noted to decrease after treatment. CONCLUSION: The Canfield Reveal imager can be used in the objective photodocumentation of subtle and modest effects of nonablative radiofrequency (Pellevé) treatment to the periorbital region.
