It is normal for the cornea to swell during the first few days after cataract surgery. Cornea swelling or edema may cause some short-term blurriness. Normally, swelling will subside within a few days and vision becomes clear. Rarely, corneal swelling may not improve. This occurs when the cornea is weaker, like in Fuchs’ Dystrophy, or when the cataract is very dense and difficult to remove.
Treatment for Corneal Swelling
In patients who have persistent corneal swelling after cataract surgery, it may take one to three months to determine if the cornea swelling will improve on its own. If the cornea swelling is mild it may not affect your vision and no treatment is needed. If some mild early morning blurry vision occurs, eye drops can be used to reduce some of the swellings. In those infrequent cases in which cornea swelling persists, a corneal transplant may be necessary to restore vision.
The surgeons at Northeast Ohio Eye Surgeons are at the forefront of corneal transplant technology. To treat corneal swelling, Dr. Jones and Dr. Lohman use the most advanced techniques of corneal transplantation — DMEK and DSAEK. These procedures provide the best vision and fastest visual recovery possible for patients with corneal swelling. With DMEK and DSAEK, 99% of your cornea is left intact and only the damaged innermost layer of the cornea is replaced. It is sometimes possible to restore 20/20 vision with these advanced surgeries.
