Are my eyes healthy?

The outcome of surgery depends in part on the condition of the cornea and overall health of your eyes. For example, the cornea itself needs to be a certain thickness and in good condition. Healthy eyes are more likely to heal well and have good treatment outcomes.

Your eye surgeon asks detailed questions about your eyes. The surgeon tests for any conditions that might result in complications or poor outcomes. These include:

• Thinning or damage to the cornea or a family history of diseases of the cornea.
• History of viral infections, disease or injury of the eyes.
• Dry eyes, which can worsen with surgery.
• Large pupils or small corneas, both of which can lead to vision complications.
• Disease of the optic nerve called glaucoma.
• Cloudy lenses called cataracts.
