Can dryness in my eye cause blurry vision after PRK?

Dry eye following laser vision correction of any kind, whether that is PRK or LASIK, can cause fluctuations in vision. One way to assess if dry eye might be the cause is to resume artificial tears. If your vision clears with the use of artificial tears, dry eye may be at the root of your problem. However, blurred vision can be the result of many things. The only way to tell if your vision is affected by dry eye or some other reason is to contact your eye doctor, who will perform a complete exam to determine the exact cause.
