Blurred vision after PRK operation Blurred vision after PRK is completely normal, so don't worry about your poor vision. Different people will experience varying degrees of discomfort or pain, usually 30 to 90 minutes after the PRK procedure. First, on the second day after the patient may also experience a lot of pain. **Causes of blurred vision and reduced vision after PRK operation** As mentioned above, for the first few days after PRK surgery, a person may have good vision. But while the surface layer of the cornea is healing, the patient's vision may deteriorate again. And the dressing lens is placed on the eye for 7 days until the epithelium tissue is formed. After removing the dressing lens, with each blink, the uneven surface of the epithelium due to blinking is smoothed and polished, and the quality of your vision is also improved. It may take several weeks to regain full vision, which varies depending on the individual's eye condition. But in general, most patients have to wait several weeks to return to normal vision. The cornea lasts for at least 2-3 months after the operation. During this time, the epithelium tissue, which is the most superficial layer of the cornea, returns to its normal state and the vision becomes completely clear. Using eye drops and artificial tears is very effective in this process. Rate this post
