PRK

Photorefractive Keratectomy (PRK) is an established and successful laser vision correction technique. For those who long for clear vision without the need for glasses or contact lenses, PRK offers a safe and effective solution. This procedure has been used successfully to correct refractive errors such as nearsightedness, farsightedness, and astigmatism for more than 20 years with positive outcomes. 

Furthermore, PRK has minimal risks compared to other corrective surgeries that may provide similar results. Clear vision is vital to our daily activities and quality of life; therefore, PRK may be a viable option if you want durable visual acuity improvement without the use of eyeglasses or contact lenses.

Laser Vision

PRK is a form of laser vision correction that uses a laser to reshape the cornea and correct refractive errors. This treatment offers an alternative to glasses or contact lenses, providing enhanced vision. Small amounts of tissue are removed with a laser from the cornea, allowing light to focus correctly on the retina. It’s important for anyone considering PRK surgery to have a full understanding of its benefits and potential risks prior to proceeding with the procedure.

Understanding the Mechanics of Vision: How the Human Eye Works

The human eye is a highly complex organ which allows us to experience one of our most fundamental senses – sight. Light enters the eye through the cornea, which is a clear outer layer at the front of the eye. This light is then refracted and focused on the retina, located at the back of the eye. The retina then converts these rays into electrical signals sent to the brain, which are finally interpreted as visual images. 

Various optical conditions can affect our perception of sight due to an irregularly shaped cornea. Refractive errors such as nearsightedness, farsightedness and astigmatism all stem from this irregularity in refraction when light cannot align correctly with the retina.

Advanced Laser Vision

PRK is an advanced laser vision correction procedure that has been used successfully for many years. During the process, the cornea is reshaped to improve its ability to focus light correctly on the retina. This is achieved by using a laser to remove a small amount of tissue from the cornea. PRK is a safe and effective procedure that can provide clear vision without the need for glasses or contact lenses. It is suitable for patients with nearsightedness, farsightedness, or astigmatism, and it can correct refractive errors ranging from mild to severe.

The surgeon will first numb your eye with anaesthetic drops before removing the outer layer of skin on your cornea using a special diamond knife. A protective shield will be placed over your eye while it heals so there’s no risk of infection or scarring while you wait for your vision to return. You’ll then be given protective goggles until your next appointment when you’ll undergo another procedure called “touch-up PRK surgery” in order to fine-tune the results. The entire process normally takes about 30 minutes per eye but varies depending on the individual needs and preferences of each patientThe surgical procedure for laser vision correction is performed under local anesthesia, so you will not feel any pain during the process.During the course, our team will use a small incision in your eye to remove a portion of the tissue in your cornea. The excised tissue is then reshaped to create a new surface that helps focus light properly onto your retina. This reshaping allows light rays entering your eye to focus directly onto the retina, which improves visual acuity and reduces or eliminates dependence on corrective lenses or glasses to see clearly.After surgery, patients typically experience some discomfort and blurry vision while their eyes heal. Most patients achieve clear vision within a few days or weeks after surgery, although this varies depending on the specific type of vision correction procedure performed.
