REFRACTIVE SURGICAL PROCEDURE-PRK:

Refractive surgery is a surgical treatment that corrects the eye's refractive error (spectacle power). It's frequently done to eliminate or lessen the need for glasses or contact lenses.

An artificial lens (intraocular lens) can be implanted into the eye in addition to or instead of the natural lens: phakic intraocular lenses (PIOL) are implanted into the eye without removing the natural lens, whereas a refractive lens exchange (RLE) requires the lens to be removed.

Refractive operations including corneal reshaping have a success rate of over 90%. Up to 95% of persons who had PRK surgery were able to attain 20/20 vision without the use of corrective lenses.

Laser eye surgery treatments such as photorefractive keratectomy and laser-assisted sub-epithelial keratectomy are used to correct a person's eyesight and reduce the need for glasses or contact lenses.

The cornea, the clear outer layer of your eye that focuses light so you can see well, is reshaped with a laser in both LASIK and PRK. They go about it in slightly different ways, though. In LASIK, a thin flap is created in the cornea. The outer layer of the cornea is removed during PRK, but it grows back over time.

PRK surgery involves reshaping the corneal tissue to address the refractive faults that the patient has and improve their vision. There's no assurance that you'll be able to see clearly without the use of glasses or contact lenses, however this is the case for the vast majority of patients.

Disease Overview:

Refractive error

Because of the geometry of the eye and/or cornea, refractive error, also known as refraction error, is a problem in precisely focusing light on the retina.

When the shape of your eyeball prevents light from properly concentrating on your retina, you have a refractive error. The shape of your cornea and lens alters if your eyeball is longer or shorter than usual, producing an incorrect picture to be projected on your retina in the rear of your eye. The visual messages to your brain are distorted as a result of this. Another reason of refractive error is the lens in your eye changing shape as you get older.

Disease Signs and Symptoms:

• Double vision is a common occurrence.
• Vision is hazy.
• A halo or glare appears surrounding brilliant lights.
• Squinting.
• Headaches.
• Strain on the eyes (when your eyes feel tired or sore)
• When reading or staring at a computer, you have trouble focusing.

Disease Causes:

Refractive errors can be caused by a variety of factors, including: eyeball length (when the eyeball grows too long or too short) Problems with the cornea's shape (the clear outer layer of the eye) Lens deterioration (an inner part of the eye that is normally clear and helps the eye focus)

Disease Diagnosis:

During a typical eye checkup, an eye care practitioner can detect a refractive mistake. Typically, patients are asked to read a vision chart while trying on a variety of lenses in order to maximise their vision. It is unusual that additional imaging or testing is required.

Disease Treatment:

Eyeglasses, contact lenses, and surgery are the most frequent treatments for refractive problems. Eyeglasses are the most straightforward and secure method of correcting refractive errors. To offer you with best vision clarity, your ophthalmologist might prescribe specific lens dimensions in your eyeglasses to modify the refracted focal point and position it directly on your retina.

Before the light reaches the lens and cornea, contact lenses refract or bend it, resulting in a more exact focus or refraction. Contact lens wearers often have a broader field of vision and sharper eyesight than those who use glasses. Contact lenses are both effective and safe as long as they are fitted properly and cared for properly.

To avoid infection, it's critical to follow the directions and standards for washing your hands and cleaning your lenses. Some eye diseases make contact lenses impossible to wear. Check with your eye doctor to see if you have any of these problems.

Refractive surgery is a procedure that alters the shape of your cornea permanently. The enhanced shape of your cornea improves your eye's focusing capabilities by allowing light rays to focus appropriately on your retina. Consult your ophthalmologist to see whether refractive surgery is a possibility for you.

If you are experiencing any unusual visual symptoms, you should always contact with a physician for a complete evaluation and examination so that an appropriate diagnosis and treatment plan can be determined, since it might be a symptom or indicator of a serious sickness or condition.
