5 Key Takeaways
-
1
Scleral lenses (SLs) can alleviate dry eye symptoms but may still cause discomfort despite optimal fitting.
-
2
Key factors contributing to discomfort in SL wearers include evaporation, peripheral exposure, and eyelid friction.
-
3
Mechanical irritation from SL edges can exacerbate conjunctival desiccation and tear film instability.
-
4
Lid wiper epitheliopathy (LWE) is a significant source of discomfort, linked to insufficient ocular lubrication.
-
5
Improving comfort in SL wearers requires optimizing tear film and minimizing friction, beyond just lens fit.
