Fig 2. Improvement of tear film break up time (BUT), Oxford grade, meibomian gland expressibility (MGE), meibum quality (MQ), and ocular surface disease index (OSDI) after treatment.

Group 1 received IPL plus MGX at the first and second treatment sessions and IPL alone at the third and fourth treatment sessions. Group 2 received IPL alone at the first and second sessions and IPL plus MGX at the third and fourth sessions. At baseline (BL), the two groups were comparable in every parameter. However, at the first follow-up (FU1), group 1 showed improved BUT (*). At the second follow-up (FU2), none of the parameters differed between group 1 and group 2.
