The doctors or ophthalmologists there will explain the whole procedure, including what you shall expect from the procedure. Moreover, they will conduct some tests to determine whether or not you're eligible for PRK laser eye surgery.

Here are the following conditions you must meet to be eligible for PRK:

  • You must be at least 18 years old.

  • Have a prescription for corrective lenses that has not been updated in the past year.

  • You must be suffering from the refractive error that must be treatable with PRK.

  • The cornea and overall health of your eye must be good.

  • Are still nursing your infants

  • Have cataracts

  • Are suffering from dry eye syndrome or blepharitis in addition to an eye infection.

  • Have wounds in the corners of your eyes.

What Can I Expect During the PRK Procedure?


You will receive a number of eye drops designed to numb your eyes before the PRK laser eye surgery. It is to ensure that you do not experience any pain or discomfort while the procedure is being performed. You can also be prescribed an oral tranquilizer to help you relax.


During the process, your eye doctor will insert a little device called an eyelid holder into your eye, which will hold your eyelids open in a comfortable manner.


Then, your ophthalmologist will use a soft brush on your cornea's outermost layer, known as the epithelium, to remove it. After that, your eye surgeon will reshape your corneal tissue using a laser that has a very high degree of accuracy.


Following the surgical process, your ophthalmologist will apply a bandage that resembles a contact lens to your eye in order to help it heal and to make you feel more comfortable.


What is the PRK Result?


During the PRK procedure, a specialized bandage that looks somewhat like a contact lens is placed over the eye in order to assist in the regeneration and healing of the surface layer of the cornea.


Your doctor will ask you to have the bandage until your eyes are completely healed. When the surface has fully recovered, your eye surgeon will then remove the lens kind bandage.


During the healing time, you may experience blurry vision, irritation, or sensitivity to light. All of these symptoms are normal. However, if you feel too much of problems, you must visit your eye surgeon.


In addition, you will also be provided with some pain medication to take for the first day or two afterward. Aside from that, your surgeon will also provide you with eye drops to use as recommended.


Typically, the initial recuperation period lasts for a couple of days. After that initial phase of healing, the vision not only stabilizes but also becomes highly functional.


After the bandage lens has been removed, the majority of patients are able to return to their routine activities, including returning to work, even though full recovery may take roughly a month. Usually, patients experience a gradual improvement in their vision after the PRK laser eye surgery.

There are certain things that you need to follow before undergoing PRK eye surgery, which are as follows:

1. Contact lens wearers must switch to eyeglasses and refrain from using contact lenses for a period of four weeks before undergoing PRK laser eye surgery.

After that, it takes the cornea a very long time to return to its normal form.


2. Meet a reputable eye surgeon or visit a reputable eye clinic for your PRK eye surgery. It is because professional eye surgeons provide you with all the information you need before PRK. Moreover, they will explain to you the procedure and what you shall expect from this surgery.

Also, discuss what other surgeries are available to you, the potential risks and complications of the procedure, what to expect from the procedure, and what the pre and post-surgery guidelines are.


4. In the days leading up to your procedure, your eye doctor may recommend that you gently but often brush your eyelids and lashes in order to remove any oil or debris that has accumulated there.


5. You'll have to stop taking any medications that treat your cold or allergies at least four days before the procedure. Also, you'll be asked to stop taking any medications that thin your blood for a certain amount of time before the procedure.
