Corneal dystrophies are inherited conditions that gradually cloud or distort the cornea, often affecting both eyes. As vision becomes hazy or irregular, everyday tasks get harder — but specialty lenses can help. At Michigan Contact Lens, Dr. Shira Kresch fits custom scleral lenses that smooth an irregular surface and restore clearer, more comfortable vision for patients with corneal dystrophy.
Corneal dystrophies are a group of mostly inherited disorders in which abnormal material builds up in one or more layers of the cornea. They typically affect both eyes, progress slowly, and are not caused by injury or outside factors.
There are many types, grouped by the corneal layer they affect — including Fuchs’ dystrophy (innermost layer), map-dot-fingerprint dystrophy (surface layer), and lattice or granular dystrophies (middle layer). Each affects clarity and comfort differently.
Most corneal dystrophies are genetic and run in families. Common types include:
Because they’re progressive, dystrophies benefit from ongoing monitoring by a corneal specialist.
Symptoms vary by type but often include:
When a dystrophy makes the corneal surface irregular, a scleral lens can restore clarity that glasses can’t reach.
For surface and mid-layer dystrophies especially, scleral lenses offer meaningful comfort and visual improvement.
Some dystrophies — particularly advanced Fuchs’ — may eventually require surgical treatment such as a partial corneal transplant. Even then, scleral lenses can play a role before and after surgery. Dr. Kresch will help you understand where lenses fit in your long-term plan.
Corneal dystrophies are best followed over time. Michigan Contact Lens co-manages dystrophy patients with ophthalmologists and corneal surgeons across Metro Detroit, providing specialty lens care that complements your medical monitoring and any surgical treatment.
Yes — especially for dystrophies that make the surface irregular. Scleral lenses create a smooth optical surface and hydrate the eye, improving both clarity and comfort.
Most are. They’re typically inherited and affect both eyes, which is why family history and regular monitoring by a corneal specialist are important.
Not necessarily. Many patients manage well with scleral lenses. Advanced cases — particularly Fuchs’ dystrophy — may need surgery, and sclerals can still help before and after.
Often, yes. The fluid reservoir keeps the surface hydrated and shielded, which can reduce the recurrent erosions some dystrophies cause.
