Corneal edema is a swelling of the clear part in the front of your eye. Some patients may have corneal conditions which increase the risk of this complication. Patients with severe cataracts may also be at a higher risk for corneal edema.

If corneal edema occurs, it can vary from very slight to severe. If the edema is mild to moderate, the vision may be decreased. Eye drops may then be used to treat the swelling, often allowing the vision to return to normal. If the swelling does not clear, then you may need a corneal transplant to restore your vision, and your doctor can go over this procedure with you at that time. A corneal transplant is an involved procedure with a recovery period of months, but it often results in a significant improvement in the vision.
