Yes, it is true that the quality of the tear film is important to successful contact lens wear. But it is not as important with gas permeable lenses. A highly wettable lens can usually accommodate the patient with a dry eye. The downside to gas perms is that patient adaptation is usually easier in patients with a normal tear film compared to dry eye patients.

It would make sense that hard contact lenses are not good for patients with a poor tear film. It would seem as though the tear film would have trouble filling the gap between the lens and the cornea and this would generate an inconsistent index of refraction. I am just putting two random ideas together for this situation, but I am curious about contact lenses and tear film quality in patients. You should do another article! Great article Dr. Kestenbaum
