Outcome Measures

Primary Outcomes (2)

  • TBUT

    tear break-up time

    3 months

  • meibomian gland function score

    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.

    3 months

Secondary Outcomes (2)

  • OSDI

    3 months

  • Corneal staining score

    3 months

Study Arms (2)

IPL group

ACTIVE COMPARATOR

Subject who have intense pulsed light (IPL) laser 2 twice 1-6 weeks before cataract surgery

Procedure: IPL

Non-IPL group

NO INTERVENTION

Subject who do not have intense pulsed light (IPL) laser before cataract surgery

Interventions

IPLPROCEDURE

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.
