What is PRK Surgery?
Photorefractive keratectomy or PRK surgery is used to treat vision problems via laser. This kind of surgery is specifically done for patients who are experiencing a refractive defect in their eye. A refractive defect refers to a condition in which your eye fails to light appropriately.
The ultimate aim of this laser surgery is to change the shape of the cornea to help improve the focus of light rays on the retina.
PRK surgery is usually used to treat the symptoms of both near sightedness (myopia) as well as far sightedness (hyperopia).
This refractive surgery is also used for patients with astigmatism.
Once you successfully undergo the procedure of PRK surgery, you’ll notice a drastic change and improvement in your vision.
PRK surgery is most likely to lessen your need for wearing glasses or lenses. In a few cases, it’s also likely that you might as well totally do away with your glasses or lenses on a daily basis.
PRK Surgery Procedure
- The first step of the surgery involves putting drops in your eye so as to make them numb. You might also be given some medication to get rid of the pain and simply relax.
- The second step is a 30 second procedure in which the epithelium or the top most layer of coronal tissue is entirely removed.
- Any irregularities in your corneal tissue layers are fixed using “excimer laser”. The best part about this tool is that it actually helps working in the deeper layers of the cornea.
- Lastly, your surgeon will put a bandage contact lens on the top of your cornea to allow healing of your eye.
PRK Surgery Recovery
Once the surgery is complete, you will have a bandage placed over your eye to help it allow healing. Here are some things you must keep in mind as you are on the path to your PRK surgery recovery:
- On the day of the surgery, make sure that you have someone to accompany for driving you back home. As soon as you get home, make it a point to simply relax or take a nap.
- If you want your PRK surgery recovery to be quick, then you must keep away from all kinds of stressful activities for at least a week post surgery. You can also plan to take leave from work for a couple of days as per the recommendation of your doctor.
- There are chances that you’ll experience some pain in your eye for about 2-3 days post surgery. In such situations, you must always get in touch with your ophthalmologist and ask for prescription medicine or eye drops for relief.
- Religiously use eye drops prescribed by your surgeon, as it will help your heal and recover from the surgery.
- Another precaution you must take to recover from your PRK surgery is to wear dark sunglasses each time you step out of your home for as long as recommended by your doctor. Otherwise exposure to direct sunlight can have a harmful effect on your eyes, even triggering scarring and vision problems in the future.
- Your road to recovery from PRK surgery will be slow and gradual. For the first few days, you might experience a blurry vision. But, once a few days are passed, you’ll notice your vision getting to its optimum level.
PRK SURGERY RISKS
Much like any surgical treatment, PRK surgery also carries certain risk factors which can be seen as:
- Infection in the Cornea
- Experiencing glare in bright light
- Seeing a halo like shape around light
- Scarring in the eye or cornea
- Experiencing corneal haze
Other than these, PRK surgery also carries the potential risk of having your eyes and vision under corrected or over corrected.
In such cases, you always have an option to use lenses or glasses to improve your vision.
It is least likely that a PRK surgery will go wrong or cause loss of vision. Although, there is a slight risk of losing your best corrected vision and end up having a vision that is worse than before.
PRK Surgery Cost
Generally, a PRK surgery can cost anywhere from $2500 to $5000. In comparison to LASIK, PRP surgery is more costly.
The reason behind this is the fact that PRK surgery calls for more post operation procedures, such as removing the bandage or monitoring how your eyes are healing post the surgery.
Who Can Get a PRK Surgery?
Not everyone is eligible to undergo a PRK surgery. Here are certain factors that you must keep in mind before getting a PRK surgery:
- You must be over 18 years of age
- There have been no drastic changes in your vision in the last one year.
- You’re not pregnant or feeding at the time of the surgery.
- The average size of your pupil is 6 mm in a dark room.
On the whole, whether you are experiencing far sightedness or near sightedness, you can always rely on PRK surgery to help improve your vision with guaranteed results.
There are high chances of success in most PRK surgeries, making it a trusted and reliable way to get your vision improved.
In order to prepare for a PRK surgery, you must get in touch with your trusted eye surgeon and discuss your medical history in detail.
If your surgeon suggests, you can also undergo certain tests which will help measure the thickness of your cornea, refraction and other medical history to come up with the best possible results.
