Purpose
To investigate the association of Meibomian Gland Dysfunction (MGD) with preoperative parameters in patients undergoing refractive surgery.
Setting
Care-Laser center, Tel-Aviv, Israel
Methods
Patients undergoing refractive surgery between 2019 to 2024 at Care-Laser center, Tel-Aviv, Israel were included in this study. MGD was assessed in all the included patients by digital expression made by the same experienced surgeon (IK). We compared the differences of the baseline preoperative parameters of the patient with a high MGD grade and low MGD grade.
Results
A total of 3472 eyes were included in this study, 1731 patients (49.85%) had high MGD grade. The high MGD patients were older than the low MGD patients (p<0.001).
High MGD patient's use of contact lens was noted to be higher at initial presentation, compared to low MGD patients (52.91% vs. 44.51%, p<0.001). Initial best corrected visual acuity (BCVA), was better in the low MGD group (p<0.001).
Subjective sphere (p<0.001) and cycloplegic sphere (p<0.001) were significantly higher in the high MGD group. Pachymetry was significantly thinner in the high MGD patients (p<0.001). K readings including, average K (p=0.001), K minimum (p<0.001) , K maximum (p<0.01) were significantly steeper in the high MGD patients.
Conclusions
Asymptomatic high Meibomian Gland Dysfunction (MGD) patients among refractive surgery candidates are significantly older and more myopic compared to low MGD patients. High MGD is associated with higher use of contact lens, worse BCVA and thinner, more steeper corneas.
