Dry Eye Syndromes
Conditions
Brief summary
Clinical efficacy of Intense Pulsed Light(IPL) procedure in dry eye patients with meibomian gland dysfunction prior to cataract surgery.
Detailed description
IPL procedure is a device used for symptom relief and treatment of dry eye syndrome caused by meibomian gland dysfunction in adults, and its safety and long-term effects have been confirmed. The purpose of this study is to determine whether this procedure before cataract surgery is effective in improving the symptoms of dry eye syndrome after cataract surgery.
Interventions
PROCEDUREIPL
Intense pulse light (IPL) laser is used for the treatment of dry eye originated from meibomian gland dysfunction. IPL laser will be performed to patients who are planned to cataract surgery to improve dry eye.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| TBUT | 3 months | tear break-up time |
| meibomian gland function score | 3 months | By expression of eyelid, scoring of expressibility and quality of meibum will be tested. Form of secretion predominantly secreted by the eight meibomian glands in the center of the lid was evaluated as follows. grade 0, clear meibum is easily expressed; grade 1, cloudy meibum is expressed with mild pressure; grade 2, cloudy meibum is expressed with more than moderate pressure; and grade 3, meibum cannot be expressed even with the hard pressure. Higher score means a worst outcome. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| OSDI | 3 months | questionnaire to evaluate dry eye symptoms. OSDI grading (0 \ 100) was as follows: normal (0-12 points), mild (13-22 points), moderate (23-32 points), or severe (33-100 points). Higher score means a worse outcome. |
| Corneal staining score | 3 months | Punctate epithelial erosion of cornea will be evaluated with standard classification system(NEI score, National Eye Institute score). It divides the cornea into five sections and assigns a value from 0 (absent) to 3 (severe) to each section, based on the amount, size, and confluence of the PEE, for a maximum of 15 points. Higher score means a worse outcome. |
