What is the Recovery Timeline After the PRK Procedure?

Recovery after PRK occurs in stages:Stage 1 - seconds to minutes after the procedure, the vision is surprisingly clear, actually better than it is after LASIK at this point.Stage 2 - begins about 30-60 min after the procedure, as the numbing drops used during surgery wear off. The patient begins to experience mild to moderate discomfort in the eye. For most, the feeling is akin to sandy gritty sensation, and may be accompanied by some tearing, and light sensitivity. These symptoms, of varying intensity, may last for about 3-4 days. During this time the epithelial layer, or the “clear skin” of the cornea, regenerates. The discomfort is alleviated with “comfort drops” that numb the eye, artificial tears, cold compresses and if needed Motrin or Tylenol. During this stage of of recovery the vision is better than before the procedure, but is still fairly blurry.Stage 3 - Around day 4 after the procedure, the discomfort is gone, vision is good, but still a little “misty” usually for a week or two. It may take as long as a 4-6 weeks to get really crisp vision, where one can comfortably perform fine detailed tasks, or drive at night (when conditions are not optimal and really excellent acuity and contrast sensitivity is needed)Stage 4 - within the first 6 months after the procedure, the vision stabilizes and sharpens. By month 3 it becomes clear if the vision is satisfactory or a touch up should be considered. Touch up can be done 6 months after the original surgery.In the first 6 months after the procedure It is important to protect the eyes from UV light by wearing sunglasses to prevent haze formation.

Hi Typically the vision stabilizes by about the third month following PRK. If by the third month you are still having any issues with your vision, you should see your doctor for an evaluation.  

Hello, it takes anywhere between 3 to 10 days for healing to take place and normal vision to return. On an average you can expect your normal vision to return in about a week's time.

The recovery after PRK really has two stages. 

 

The fist stage is the healing of the surface of the eye, called the epithelium.  During this phase the vision is more blurry than after LASIK and some patients experience some discomfort.  This lasts approximately one week.  Once the epithelium is healed, recovery is similar to LASIK.  There is no discomfort but the vision gradually improves over several months. 

 

The second stage is the where the vision improves and heals over the next few weeks. While most patients can drive the next day after PRK and are in the 20/20 range within a few weeks, the vision continues to improve for about six months in nearsighted patients and up to a year in far-sighted patients. Typically 95%+ of patients only need 1 laser treatment to bring their vision to 20/20 or better.

Immediately after the procedure your vision will be quite good. Over the next 1-2 days, it will get a little blurrier but still functional, this is because the surface of the cornea is healing and irregular and because there is inflammation in the cornea. The cornea typically heals in 3-4 days, during this healing period some discomfort should be expected. After the cornea is healed and the bandage contact lens is removed, the vision will slowly improve over the next few weeks.
