Some corneal problems come not from an irregular shape but from a surface that can't protect or heal itself. Neurotrophic keratitis and exposure keratopathy are two such conditions — and scleral lenses can act as a protective, healing environment for these vulnerable eyes.
What these conditions are
Neurotrophic keratitis occurs when the cornea loses its normal sensation, often after nerve damage from surgery, infection (like herpes), or other causes. Because the eye can't sense irritation, it doesn't trigger the reflexes that keep the surface healthy, so damage can develop and heal poorly.
Exposure keratopathy happens when the eyelids can't fully close or cover the eye — due to facial nerve weakness, eyelid abnormalities, or other issues — leaving the cornea dried out and exposed.
In both, the cornea is left dangerously dry, at risk of breakdown, non-healing spots, and even infection.
How scleral lenses protect the eye
Scleral lenses create a sealed reservoir of saline over the cornea. For these conditions, that does something powerful:
- Constant hydration keeps a surface that can't keep itself moist from drying out
- Physical protection shields an exposed or insensitive cornea from the environment and from blinking friction
- A healing environment supports the ocular surface, which can help fragile tissue recover
- Better vision as a smoother, protected surface improves clarity
This therapeutic role is one of the most important uses of scleral lenses in medical eye care.
Careful, coordinated management
These are serious conditions that require close teamwork with your ophthalmologist or corneal specialist. Scleral lens wear is tailored precisely — the fit, wear schedule, and monitoring all matter — and it's often one part of a larger treatment plan. Some patients need specialized therapeutic devices; we'll guide you to the right level of care.
Don't wait on a vulnerable cornea
Because these conditions can worsen quietly (especially neurotrophic keratitis, where you may not feel the damage), prompt, expert care is essential. Dr. Salley evaluates and fits protective scleral lenses and coordinates with your medical team.
If your cornea needs protection it can't provide itself, scleral lenses may help. Request an evaluation at CFE Memphis.
