Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The main question it aims to answer is does the adjunctive of low-level light therapy (LLLT) to intense pulsed light (IPL) provide more beneficial treatment effects than intense pulsed light (IPL) alone in treating meibomian gland dysfunction (MGD) patients?
Participants will be randomized into 2 groups: adjunctive low-level light therapy (LLLT) to intense pulsed light (IPL) group (ALLLT +IPL) and IPL alone group.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
ALLLT + IPL group
Participants will receive a session of IPL therapy followed by LLLT therapy, once weekly for 4 weeks (total 4 treatment sessions). The IPL therapy will be performed using the Eye-light® with Optimal Power Energy® (Espansione Marketing S.p.A., Bologna, Italy), which emits the light at a wavelength of 600 nm IPL system with fluence ranging from 10 to 16 J/cm2 per eye depending on the Fitzpatrick skin scale. During IPL treatment 5 flashes of light will be applied to the skin around the eye using a handheld device; 3 along the inferior orbital rim, 1 at the lateral canthus, and 1 applied horizontally along the inferior orbital rim. The LLLT therapy will be delivered using the Light Modulation® special facial mask (Espansione Marketing S.p.A., Bologna, Italy) which will be placed on the participant's face for 15 minutes. The mask has the shape of a half-face and will emit a red light in a light-emitting diode (LED) system.
Low-level light therapy (LLLT)
LLLT therapy will be delivered using the Light Modulation® special facial mask (Espansione Marketing S.p.A., Bologna, Italy) which will be placed on the participant's face for 15 minutes. The mask has the shape of a half-face and will emit a red light in an LED system. The device has an emission power of 100 The mask has the shape of a half-face and will emit a red light in a light-emitting diode (LED) system. The device has an emission power of 100 milliwatts per square centimeter.
Intense pulsed light (IPL)
The IPL therapy will be performed using the Eye-light® with Optimal Power Energy® (Espansione Marketing S.p.A., Bologna, Italy), which emits the light at a wavelength of 600 nm IPL system with fluence ranging from 10 to 16 J/cm2 per eye depending on the Fitzpatrick skin scale. During IPL treatment 5 flashes of light will be applied to the skin around the eye using a handheld device; 3 along the inferior orbital rim, 1 at the lateral canthus, and 1 applied horizontally along the inferior orbital rim
IPL alone group
The IPL alone group will receive only a session of IPL therapy, once weekly for 4 weeks (total 4 treatment sessions). The IPL therapy will be performed using the Eye-light® with Optimal Power Energy® (Espansione Marketing S.p.A., Bologna, Italy), which emits the light at a wavelength of 600 nm IPL system with fluence ranging from 10 to 16 J/cm2 per eye depending on the Fitzpatrick skin scale. During IPL treatment 5 flashes of light will be applied to the skin around the eye using a handheld device; 3 along the inferior orbital rim, 1 at the lateral canthus, and 1 applied horizontally along the inferior orbital rim, similar to the combined group. Additionally, the special facial mask will also be placed on the participant's face for 15 minutes with no light power applied.
