Prolongation of Contact Lens Comfortable Wear Duration by CLM2 Topical Gel

This study compares contact lens comfortable wear duration, and signs and symptoms of contact lens discomfort, test versus control.

The clinical hypothesis is that CLM2 topical gel applied dermally on the forehead twice daily will be more effective than placebo (a) in reducing or eliminating ocular discomfort associated with contact lens wear, (b) prolong hours of comfortable wear, (c) prolong total hours of contact lens wear, (d) improve ease of insertion and removal of contact lens, and ( c) reduces friction between cornea/lens and lens/eyelid, without use of artificial eye drops or gels. One mechanism supporting this hypothesis is preliminary evidence of increased meibum secretion following CLM2 topical gel application.
