A corneal transplant can save your sight — but it doesn’t always restore crisp vision on its own. Many people are surprised to find their vision is still blurry or distorted after the eye has healed. The reason is usually irregular astigmatism, and scleral lenses are one of the most reliable ways to fix it without further surgery.
Why vision is often blurry after a transplant
Whether you had a full-thickness graft (PK) or a partial-thickness procedure (such as DALK), the transplanted tissue rarely heals into a perfectly smooth, round shape. Sutures, the junction between graft and host tissue, and natural healing all tend to leave the surface irregular. Glasses and soft lenses can’t correct that unevenness, which is why vision stays soft or ghosted.
How scleral lenses help
A scleral lens vaults over the entire graft and rests on the surrounding sclera, so it never presses on the transplanted tissue. Vision is then formed by the lens’s smooth front surface instead of your irregular cornea — often a dramatic improvement. The saline reservoir also protects and hydrates the ocular surface, which is valuable for eyes that are dry or sensitive after surgery. Our scleral lenses page explains the design in more detail.
Are scleral lenses safe on a graft?
When fitted by an experienced specialist, yes. The vaulting design is actually gentle on a transplant precisely because it doesn’t bear weight on the graft. Your doctor will design the lens to clear the cornea fully and will monitor the graft’s health at follow-ups. This careful, collaborative fitting is why specialty experience matters for transplant patients.
When can you be fitted?
Timing is individual and coordinated with your surgeon. Fitting typically waits until the eye has stabilized and, in many cases, until sutures have been managed or removed. Your cornea specialist and your lens doctor work together to choose the right moment.
Getting started
If you’ve had a transplant and your vision still isn’t what you hoped, you’re very likely a candidate — see who is a good candidate for scleral lenses. The fitting itself is described in what to expect at a scleral lens fitting. Bring your surgical records to your consultation so we can coordinate with your surgeon.
