简要总结

The study objective is to evaluate the long-term treatment effectiveness for adult patients with meibomian gland dysfunction (MGD) and evaporative dry eye by: 1) comparing the LipiFlow® System to a standardized daily warm compress and eyelid hygiene control therapy over a duration of 3 Months; and 2) evaluating the LipiFlow® alone and in combination with other MGD and dry eye treatments over a duration of up to 12 Months.

This is a post-market, non-significant risk, prospective and multi-center clinical trial divided into two stages. The first stage from enrollment to 3 Months is an open-label, randomized controlled design to compare the effectiveness of a single LipiFlow® System treatment to a standardized daily warm compress and eyelid hygiene Control therapy with Crossover LipiFlow® treatment of the Control subjects at 3 Months. The second stage, occurring between 3 and 12 Months, is an observational design to evaluate the effectiveness of LipiFlow® alone and in combination with other MGD and dry eye treatments over a duration of up to 12 Months. Subjects are entered into the following subgroups based on the subject's self-assessment of the adequacy of symptom relief and protocol-defined criteria for additional treatment.

  1. One LipiFlow® Treatment: Subjects who receive only one LipiFlow® treatment.
  2. Two LipiFlow® Treatments: Subjects who receive a second LipiFlow® treatment.
  3. Combination Treatment: Subjects who receive one or two LipiFlow® treatments followed by other MGD or dry eye treatment, as prescribed by the physician.

结局指标

主要结局

Stage 1 Mean Change in Total Meibomian Gland Score From Baseline to 3 Months

时间窗: Baseline and 3 Months

To assess the meibomian glands, the secretion characteristics from 15 gland orifices along the lower eyelid were evaluated under a slit lamp biomicrosope using a handheld instrument, Meibomian Gland Evaluator, to apply gentle standardized pressure to the eyelid margin. Expressed secretion characteristics were graded on a scale of 3 (clear liquid secretion), 2 (cloudy liquid secretion), 1 (inspissated/toothpaste consistency), and 0 (no secretion). Total meibomian gland score was calculated based on the sum of the secretion grades for all 15 glands over a range from 0 to 45 with a higher score reflecting less meibomian gland dysfunction. To be eligible for the study, the Baseline total meibomian gland score must have been 12 or less in each eye. Change = 3 Month score - Baseline Score.

Stage 2 Mean Total Meibomian Gland Score at 12 Months

时间窗: 12 Months

To assess the meibomian glands, the secretion characteristics from 15 gland orifices along the lower eyelid were evaluated under a slit lamp biomicrosope using a handheld instrument, Meibomian Gland Evaluator, to apply gentle standardized pressure to the eyelid margin. Expressed secretion characteristics were graded on a scale of 3 (clear liquid secretion), 2 (cloudy liquid secretion), 1 (inspissated/toothpaste consistency), and 0 (no secretion). Total meibomian gland score was calculated based on the sum of the secretion grades for all 15 glands over a range from 0 to 45 with a higher score reflecting less meibomian gland dysfunction. The total meibomian gland score at 12 Months was compared across subgroups, as defined below.

次要结局

  • Stage 1 Mean Change in Total OSDI Score From Baseline to 3 Months(Baseline, 3 Months)
  • Stage 2 Mean Total OSDI Score at 12 Months(12 Months)
