If you’re experiencing difficulty with distorted vision, Photorefractive Keratectomy (PRK) is a viable option to correct your eyesight. This type of laser eye surgery works by reshaping your cornea with precision to improve the way light enters your eye. Your cornea is the transparent outer layer of the eye, and it helps focus light onto the retina. Here are three vision issues PRK can correct:
1. Myopia
Myopia, or nearsightedness, occurs when light focuses in front of the retina as a result of a longer eyeball or steep corneal curvature. It makes distant objects blurry while objects close to the eyes remain clear. Tasks like reading a sign on the highway or a screen from across a room can be difficult. Nearsightedness may occur in children and will typically progress if left undetected.
PRK laser eye surgery reshapes the cornea to focus light directly onto the retina. The outer layer of the cornea is removed, and a laser reshapes the tissue underneath. A detailed eye scan helps the ophthalmologist determine the degree of adjustment required for vision correction. After surgery, many patients experience light sensitivity. Wearing sunglasses when outdoors and limiting screen time helps prevent eye irritation. Rest and the use of specialized eye drops promote healing, and strenuous activities should be avoided.
2. Hyperopia
Hyperopia, or farsightedness, occurs when light converges behind the retina. This may be caused by a flatter cornea or a shorter eyeball. Nearby objects are often blurry, affecting clarity when reading or using your cellphone. Your eyes may become tired after prolonged close work. Others find it challenging to shift attention from objects far away to those close by.
PRK corrects farsightedness by steepening the cornea’s curvature. This enables light to converge more accurately onto the retina. A bandage contact lens is placed on the eye temporarily to smooth the corneal surface and speed healing. Follow-up appointments with an ophthalmologist monitor healing progress and identify any issues, such as infection, that may arise.
3. Astigmatism
Astigmatism results from an irregular curving of the cornea that scatters light across multiple points on the retina. It may cause blurred or distorted vision at any distance. Some people experience halos around lights, while others notice visual fatigue when reading or working on a screen. The condition may remain stable over the years or shift minimally with age.
PRK laser eye surgery can flatten corneal irregularities. After the outer layer is removed, a guided laser reshapes the cornea, enabling light to focus evenly on the retina. Ophthalmologists will explain the healing process and any potential complications. If you notice any sudden changes in your vision or discomfort, following up with your eye doctor promptly helps address these concerns.
Benefits of PRK
PRK does not create a corneal flap, a common feature of LASIK, helping maintain the natural surface structure of your eye. This can be particularly useful if your lifestyle involves regular physical activity or if your corneas are naturally thin. Compared to LASIK, PRK is also less invasive, making it an attractive solution for vision correction. Laser surgeries are customized to each patient, and ophthalmologists tailor the position and depth according to the patient’s eye measurements. This allows you to receive targeted treatment that provides lasting results.
Schedule Laser Eye Surgery Today
A consultation with a LASIK expert determines whether you are a good candidate for laser eye surgery. The eye doctor evaluates your age, lifestyle, eye health, corneal thickness, and whether you’ve had previous surgeries. Verifying your candidacy for surgery helps verify that procedure outcomes match your vision goals. Schedule your laser eye surgery today to improve your vision and overall well-being.
