What To Expect From PRK Surgery
PRK (photorefractive keratectomy) is a widely performed laser eye surgery designed to improve vision. If you are exploring vision correction options, understanding what this procedure involves can help you make an informed decision. Here is more information about what PRK is, the conditions it addresses, what the procedure entails, and what recovery typically looks like.
What Is PRK?
PRK is a type of refractive laser surgery that reshapes the cornea to improve how light enters the eye. It was one of the first laser eye surgeries developed for vision correction and remains a trusted option today. Unlike LASIK, which creates a thin flap in the cornea, PRK works on the cornea’s surface by removing only the outer layer.
The main goal of PRK is to change the shape of the cornea so light can focus more accurately on the retina. This surgery can reduce or eliminate the need for corrective glasses or contact lenses. While advancements have led to other techniques, PRK remains a popular choice for certain individuals.
What Conditions Can It Correct?
PRK is primarily used to address common refractive errors. These include myopia (nearsightedness), where distant objects appear blurry, and hyperopia (farsightedness), which makes nearby objects harder to see. People with astigmatism, a condition that causes blurred or distorted vision due to an irregularly shaped cornea, may also benefit from PRK.
It is often recommended for individuals who may not be eligible for surgeries like LASIK. This includes those with thinner corneas, as PRK does not require cutting a corneal flap. While PRK addresses many refractive errors, not everyone is a candidate. A consultation with an eye specialist is necessary before moving forward.
What Is the Procedure Like?
PRK is a relatively straightforward outpatient procedure performed by an ophthalmologist. Before surgery begins, anesthetic eye drops are administered to numb the eye. The outer layer of the cornea, called the epithelium, is gently removed using a specialized tool or solution.
Once the epithelium has been removed, an excimer laser is used to reshape the cornea. This laser delivers targeted pulses of light to correct the refractive error. After the laser reshaping is complete, a protective contact lens is placed over the eye to aid healing.
Patients are usually awake during the surgery but may receive medication to help them stay relaxed. The procedure is generally painless, thanks to the numbing drops used beforehand. Some patients report feeling mild pressure at certain moments during the surgery.
What Is Recovery Like?
The recovery process for PRK involves a gradual improvement in vision over several weeks. PRK requires the outer layer of the cornea to heal first. This healing process can take three to five days, during which time patients may experience some discomfort, light sensitivity, and blurry vision.
Doctors often prescribe eye drops to manage discomfort and prevent infection. Follow-up appointments are scheduled to monitor healing and track progress. Vision continues to stabilize and improve over the next few weeks or months, depending on the individual.
Patients are advised to follow their ophthalmologist’s aftercare instructions carefully. Activities like swimming or using eye makeup may need to be avoided during the initial healing period. Full recovery can take up to three months, though many patients notice clearer vision well before this point.
Take the First Step Toward Clearer Vision
PRK is a trusted option for individuals seeking effective vision correction. Its ability to address refractive errors without creating a corneal flap makes it a unique alternative to other laser procedures. If you’re exploring PRK, the next step is to consult an eye specialist who can help determine if it’s the right choice for you. Schedule a consultation today and take the first step toward clearer vision and greater visual freedom.
