An irregular cornea is any cornea that is not evenly round or that shows asymmetry between its two halves. Several underlying eye conditions can lead to this problem.
An irregular cornea disrupts the way light enters the eye, often causing blurred or distorted vision that routine contact lenses cannot correct.
Most irregular corneas arise from congenital or inherited conditions.
When a corneal disease reaches an advanced stage, a transplant may become necessary. Although the surgery can restore clarity, it often leaves the cornea with an uneven surface.
Fuch’s corneal dystrophy, keratoconus, corneal scars, and epithelial basement membrane dystrophy are common reasons for a corneal transplant.
After a transplant the cornea may show ridges, steep areas, or flat zones that interfere with vision. These surface changes are treated in the same way as other irregular corneas.
Eye surgeries unrelated to the cornea can also leave the front of the eye uneven.
A trabeculoplasty or similar glaucoma surgery can create a raised bleb that distorts the corneal surface and makes fitting a traditional scleral lens difficult.
Any procedure that alters the white part of the eye can lead to bumps or scars that change how a contact lens sits on the eye.
When standard scleral lenses do not provide clear vision or comfort, a custom molded lens becomes the next option.
An impression material similar to that used in dentistry is placed on the eye to capture every contour, including blebs and graft edges. The mold contains more than three million data points and represents the exact curvature of the eye.
The impression is scanned in 3D at the laboratory, and a lens is crafted to match the unique shape of the eye. Once the lens arrives, it is placed on the eye, and the fit and vision are confirmed.
For patients who struggle with standard contact lenses, a fully customized scleral lens can restore functional vision and day-long comfort.
The EyePrint process aligns the lens with both large and small irregularities, including combined issues such as a corneal transplant plus a glaucoma bleb.
A lens that mirrors the eye’s shape stays centered, reduces friction, and maintains consistent vision throughout the day.
Patients who cannot achieve clear vision or comfort with standard scleral lenses, or who have multiple ocular surface irregularities, are good candidates for an EyePrint prosthetic.
Our team is committed to finding the best contact lens solution for each eye, no matter how complex. Together, we can help you enjoy sharp, comfortable vision and a better quality of life.
