To evaluate the efficacy, convenience and cost of long term use of twice daily warm compresses and eyelid hygiene as compared to a single, in-office thermal pulsation treatment (LipiFlow System), which applies simultaneous heat and pressure to the eyelids, in patients with meibomian gland dysfunction (MGD) and dry eye.

In a prospective, multicenter, open-label, randomized clinical trial, 99 subjects (197 eyes) received a single 12-min thermal pulsation treatment and 98 subjects (196 eyes) received twice daily warm compresses (EyeGiene System) and eyelid hygiene (OCuSOFT Lid Scrub) for 3 mo. Subjects had MGD based on meibomian gland (MG) secretions and dry eye symptoms based on OSDI questionnaire. Changes in MG secretions and dry eye symptoms scores from baseline-3 mo. were compared between groups  (n=196 and 188 eyes).  Compliance with use and cost of treatment were evaluated. Subjects receiving single thermal pulsation treatment were followed to 12 mo. (n=188 eyes).

Thermal pulsation group had significantly greater mean improvement than compress and hygiene group from baseline to 3 mo. in MG secretions (6.2 ±3.7 to 17.8 ±10.6 vs. 6.3 ±3.6 to 10.8 ±8.0; p<0.0001) and dry eye symptoms (45.6 ±21.1 to 21.6 ±19.8 vs. 51.8 ±23.1 to 33.5 ±25.5; p=0.0068).  Over 3 mo., 15% of subjects used compresses and hygiene <7 times/week despite 14/week instructions.  Costs of compresses and hygiene for twice-daily use over 1 year vs. thermal pulsation treatment were similar.  Thermal pulsation group had sustained mean efficacy at 12 mo. in MG secretions (17.3±9.1) and dry eye symptoms (21.6±21.3).

Compared to twice daily warm compresses and eyelid hygiene over 3 months, a single thermal pulsation treatment is significantly more effective in improving MG secretions and dry eye symptoms, shows sustained efficacy over one year at a similar cost, and is more convenient without the need for daily patient compliance.
