Preoperative iLux on Cataract Surgery Derived Dry Eye Disease Due to Meibomian Gland Dysfunction

The Efficacy of the Systane iLux System on Preoperative Cataract Patients on Dry Eye Disease Due to Meibomian Gland Dysfunction

This prospective study will investigate the effect of pre-operative Systane iLux system administration in treated cataract induced dry eye disease.

Eligible patients to be recruited will have scheduled upcoming senile cataract surgery. Enrolled patients in the active arm (n=25) will receive pre-operative Systane iLux treatment two weeks prior to surgery at the baseline visit. Patients in the control arm will receive no Systane iLux treatment at the baseline visit two weeks prior to cataract surgery. Patients will be assessed on baseline metrics for dry eye disease stemming and meibomian gland dysfunction (MGD) at the baseline visit two weeks prior to cataract surgery. These metrics include tear break up time (TBUT), standard patient evaluation of eye dryness questionnaire (SPEED), ocular surface and surface disease index (OSDI) surveys, and lipid layer thickness (LLT). At the follow up visit four weeks after cataract surgery, these same metrics will be assessed again for any significant changes.
