Brief Summary
This study aimed to determine the therapeutic effectiveness of different machines in intense pulsed light (IPL) treatment of meibomian gland dysfunction (MGD). Subjects diagnosed with MGD underwent three sessions of IPL treatment in a control (M22) treatment group or experimental (OPL-I) treatment group and were followed up three to four weeks after each session. Tear breakup time (TBUT), meibomian gland secretion scores (MGSS), meibomian gland meibum scores (MGMS), corneal fluorescein staining (CFS) scores, and the Standard Patient Evaluation of Eye Dryness (SPEED) was used to assess eye dryness signs and symptoms at baseline and follow-up visits.

Outcome Measures
Primary Outcomes (5)
SPEED Scores
Standard Patient Evaluation of Eye Dryness questionnaire
Baseline, 1 month, 2 months, 3 months, 4 months
CFS scores
corneal fluorescein staining scores
Baseline, 1 month, 2 months, 3 months, 4 months
TBUT
Tear breakup time
Baseline, 1 month, 2 months, 3 months, 4 months
MGSS
Meibomian gland secretion scores. The MGSS evaluates the obstruction of meibum along the lower eyelid. Three positions along the lower eyelid were detected (five nasal, five central, and five temporal meibomian glands). A score of 0 indicated secretion by all five glands, a score of 1 indicated secretion by three to four glands, a score of 2 indicated secretion by one or two glands, and a score of 3 indicated no secretion by any glands.
Baseline, 1 month, 2 months, 3 months, 4 months
MGMS
meibomian gland meibum scores. The MGMS evaluates the quality of meibum along the lower eyelid, with a score of 0 indicating clear liquid meibum, a score of 1 indicating cloudy liquid meibum, a score of 2 indicating cloudy granular meibum, and a score of 3 indicating toothpaste-like solid meibum).
Baseline, 1 month, 2 months, 3 months, 4 months

Interventions
Each MGD patient underwent three treatment sessions at three-week intervals and three follow-up examinations over the course of treatment.
0.3% hyaluronic acid eye drops (Hialid; Santen, Osaka, Japan) four times a day during the study, including the follow-up period.
Eligibility Criteria
You may qualify if:
- Fitzpatrick skin type I-IV according to sun sensitivity and skin appearance
- A Standard Patient Evaluation of Eye Dryness (SPEED) score of ≥6
- Tear breakup time (TBUT) of ≤10 s in the studied eye
- Corneal fluorescein staining (CFS) score of ≥1 (it is not necessary to consider this criterion if the TBUT is ≤5 s)
- Meibomian gland secretion score (MGSS) of ≥6 in the studied eye.
You may not qualify if:
- Use of prescription eye drops (excluding artificial tears) within 48 hours of recruitment
- Facial IPL treatment within the prior 12 months
- Any surgery of the eye or eyelids within the prior six months
- Ocular surface and eyelid abnormalities
- Any systemic condition that might cause eye dryness
- Use of photosensitive drugs within the prior three months
- Precancerous lesions
- Skin cancer or pigmented lesions in the treatment area
- Overexposure to the sun within the previous month
- Ocular infections within the previous six months
- Uncontrolled infections or immunosuppressive diseases
