Evaluation of the Safety and Efficacy of Intense Pulsed Light Treatment with Meibomian Gland Expression of the Upper Eyelids for Dry Eye Disease.

To investigate the safety of and change from baseline of tear breakup time and visual analog pain scales in dry eye disease subjects with upper lid Meibomian gland dysfunction after intense pulsed light (IPL) treatment assessing global ocular pain severity, ocular pain frequency, and ocular pain in the previous 24 h. This is a prospective single-site study. All patients received active treatment consisting of four treatments spaced no fewer than 2 weeks apart and no longer than 4 weeks apart. The IPL therapy was performed with a Lumenis M22 (Lumenis Ltd., Yokneam, Israel) xenon-based micropulsed IPL utilizing a 590 nm filter with a 6 mm clear SapphireCool cylindrical lightguide for the upper lids with a fluence of 10 J/cm across the upper eyelids, including the tragus for two passes. Patients then received expression of their meibomian glands using two cotton-tipped applicators. Tear breakup data were collected as well as global ocular pain, ocular pain episodes in the past 24 h and frequency of ocular pain episodes. All of the assessments for the treated eyes improved over the course of treatment. Statistically significant physician increases in measured tear breakup times were measured for each eye independently. Statistically significant decreases in global eye dryness scale, eye dryness in the preceding 24 h, and frequency of ocular pain episodes between treatments were observed. There were no serious or nonserious adverse events in the trial. This pilot study suggests that a new specialized 6 mm cylindrical handpiece for the M22 Lumenis IPL machine is safe and effective in increasing physician-measured tear breakup time as well as several scales of the symptoms of ocular dryness, including global symptoms, frequency of symptoms, and ocular dryness occurring within the previous 24 h before the study visit.
