Purpose:
The study aimed to determine changes detected by noncontact meibography and noninvasive break-up time test (NIBUT) in individuals with regular use of soft contact lenses and compare these findings with irregular soft contact lenses wearers who not compliant with them and non-wearers control group.
Patients And Methods:
A prospective nonrandomized case-control study in which individuals were recruited and distributed into three groups: Group A (regular contact lens wearers), group B (irregular contact lens wearers), and group C (non-wearers). Ocular Surface Disease Index (OSDI) was obtained. Noncontact meibography and noninvasive tear break-up time were measured without lenses on using Sirius® Scheimpflug Camera.
Results:
One hundred sixty-six eyes of 83 individuals were included; 36 eyes in group A, 50 eyes in group B, and 80 eyes in group C. The mean total meiboscore was 1.99, 1.61, and 1.28, respectively. The mean meibograde was 3.03, 2.86, and 1.99, respectively. Noninvasive break-up time (NIF-BUT) was 8.42, 11.76, and 13.57 seconds, respectively.
Conclusion:
There is a difference in OSDI score, meibomian score, and break-up time between different study groups. The study results show that there are trends in lens wearers and non-lens wearers. This is useful for the field to understand the differences between lens wearers and non-lens wearers.
