Purpose: To determine the prevalence of Meibomian gland dysfunction (MGD) in contact lens wearers and the effect of different modalities of contact lens (CL) on parameters related to MGD in Thai population.
Study design: Cross-sectional study.
Methods: 75 contact lens wearer subjects (ages 20-50 years old). The subjects’ health history and symptoms were assessed using questionnaire. The assessment of MGD and dry eye symptoms was conducted by a self-reported ocular symptom using ocular surface disease index (OSDI).
Results: There was a significant association between the severity of MGD and artificial tear used, participants who used artificial tear have less severity of MGD 1.36 compare to non-used group 1.63 (P = 0.01). It was found that severity of MGD had a significant correlation with color of CL (P = 0.023). The tinted and big eye CL seemed to produce higher degree of MGD comparing to clear CL, suggesting that CL material was significantly related to severity of MGD. Short time of CL wear per day seems to have lower severity of MGD.
Conclusion: MGD was found to be common in Thai contact lens wearers’ subjects, up to 74.7 %. The severity of MGD had significant correlation with color of CL used.
