Brief Summary:
The aim of the current study is to examine the contribution of intense pulsed light (IPL) for relieving signs and symptoms of dry eye due to meibomian gland dysfunction. The effect of IPL will be examined in a study designed as a randomized controlled trial. In the study arm, subjects will undergo 4 treatment sessions, consisting of IPL pulses immediately followed by meibomian gland expression (MGX). In the control arm, subjects will undergo the same treatments, except that the IPL pulses will be disabled. For each subject, the duration of the study will be 10 weeks, as explained in the detailed description.

Condition or disease Intervention/treatment Phase
Dry Eye Syndrome Device: IPL Device: Sham IPL Procedure: MGX Not Applicable

Detailed Description:

Outcome measures (tear break-up time,meibography, self-assessed symptoms and close up photos of the lid margins) will be measured at baseline. All subjects will receive 4 treatments at 2 weeks intervals. In each treatment session, a subject allocated to the study group will be treated with intense pulsed light (IPL) administered in the malar region, from tragus to tragus including the nose, 2-3 mm below the lower eyelids. Immediately following the IPL administration, the subject will undergo meibomian gland expression (MGX) in both eyelids of both eyes. Subjects in the control arm will receive exactly the same treatment, except that the IPL administration will be sham. A single follow-up will occur at 10 weeks after the baseline (or 4 weeks after the 4th treatment session). At the follow-up, the changes in the outcome measures will be evaluated, and compared between the two arms.

For each subject, the duration of the study will be 10 weeks: 1st treatment at baseline; 2nd treatment at 2 weeks after baseline; 3rd treatment at 4 weeks after baseline; 4th treatment at 6 weeks after baseline; and a single follow-up at 10 weeks after baseline).

Statistically significant differences between the two arms will support the study hypothesis that IPL treatment itself provides relief to both signs and symptoms of dry eye disease.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 50 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: Subjects will be randomized 1:1 to a study arm and a control arm. Subjects in the study arm will be treated with IPL and meibomian gland expression. Subjects in the control arm will be treated with sham and meibomian gland expression.
Masking: Single (Participant)
Masking Description: Subjects in the study arm will receive a series of IPL pulses using the M22 IPL handpiece. In subjects of the control arm, the device will be disabled. The subject will feel the lightguide on the skin, will hear clicking sounds, but no light will be actually produced by the M22 device. Since during treatment both eyes of the subject will be fully occluded, no subject will be able to see if the treatment is actual or sham. There is no way to completely mask the subjects, since the IPL generally causes slight redness of the skin, and in some patients is may also cause some discomfort

Arm Intervention/treatment
Experimental: IPL followed by MGX
Subjects in the experimental arm with receive IPL followed by MGX: IPL pulses will be administered on the skin of the malar region (both cheeks, from tragus to tragus including the nose) and below the lower eyelids. Following IPL therapy, subjects will undergo MGX of both eyelids in both eyes.
Device: IPL
Intense pulsed light (IPL) is a non-invasive and non-laser light treatment that is FDA-approved for various conditions in dermatology. Subjects will receive a total of 4 IPL treatments over the course of the study, at intervals of 2 weeks. Each treatment will include applications of 10-15 IPL pulses in the malar region and close to the lower eyelids, followed by meibomian gland expression.

Procedure: MGX
Meibomian gland expression (MGX) will be implemented by squeezing the meibomian glands with the aid of two Q-tips positioned on either side of the meibomian glands, or with a meibomian gland expressor forceps

Sham Comparator: Sham IPL followed by MGX
Subjects in the sham comparator arm with receive Sham IPL followed by MGX: Sham IPL pulses will be administered on the skin of the malar region (both cheeks, from tragus to tragus including the nose) and below the lower eyelids. Following Sham IPL therapy, subjects will undergo MGX of both eyelids in both eyes.
Device: Sham IPL
Sham intense pulsed light (IPL) will be implemented with an IPL device in which all light is blocked by a filter. Subjects will receive a total of 4 sham treatments over the course of the study, at intervals of 2 weeks. Each treatment will include applications of10-15 sham pulses in the malar region and close to the lower eyelids, followed by meibomian gland expression.

Procedure: MGX
Meibomian gland expression (MGX) will be implemented by squeezing the meibomian glands with the aid of two Q-tips positioned on either side of the meibomian glands, or with a meibomian gland expressor forceps
