Corneal opacity is a disorder of the cornea, the transparent structure on the front of the eyeball, which can cause serious vision problems. Corneal opacity occurs when the cornea becomes scarred. This stops light from passing through the cornea to the retina and may cause the cornea to appear white or clouded over.
There are many causes of corneal opacity. In some cases, your doctor can recommend a treatment that will reverse the opacity and lessen your chance of needing additional treatment, such as surgery.
The following factors increase your chance of developing corneal opacity. If you have any of these risk factors, tell your doctor:

If you experience any of these symptoms, do not assume it is due to corneal opacity. These symptoms may be caused by other health conditions as well. If you experience any one of the following, see your eye doctor immediately:
Your doctor will ask about your symptoms and medical history, including illnesses and injuries, and perform a physical exam.
To prepare for a comprehensive eye exam, your doctor may put drops in your eyes to numb them and to dilate the pupils. Your doctor will use a slit lamp (specialized microscope) to focus a high powered beam of light into your eye to examine the cornea and other structures in your eye.
Talk with your doctor about the best treatment plan for you. Treatments vary depending on the most likely cause of the scarring and how severe the scarring is. Treatments may include:
In some cases, scar tissue may be removed surgically. The surgery may be performed using a laser, called phototherapeutic keratectomy (PTK), if the scarring is close to the corneal surface. In more severe cases, a cornea transplant may be necessary.
