PRK and LASIK Surgeries Post 1

Anyone who has ever worn glasses or contact lenses knows of the hassles. Who wouldn’t prefer just to wake up in the morning and see the wall or the ceiling clearly? Or to spontaneously take a nap without worrying about taking off your contact lens? Not surprisingly more and more people are choosing to correct their vision through surgery.

PRK (Photorefractive Keratotomy) and LASIK (Laser In Situ Keratomileusis) are two laser eye surgery procedures. Both produce the same outcome. However the procedures are slightly different, although both use lasers to reshape the cornea. The PRK procedure has a high success rate, with a record of low complications. Patients of the LASIK procedure, on the other hand, experience less post-surgical pain.

What is Treated?
PRK and LASIK are used to treat myopia (nearsightedness — a vision condition in which nearby objects are seen clearly, but far-away objects do not come into proper focus. Nearsightedness occurs if your eyeball is too long or the cornea has too much curvature, so the light entering your eye is not focused correctly), hyperopia (farsightedness — a vision condition in which distant objects are usually seen clearly, but close ones do not come into proper focus.

Farsightedness occurs if your eyeball is too short or the cornea has too little curvature, so light entering your eye is not focused correctly), as well as astigmatism (a vision condition that occurs when the front surface of your eye, the cornea, is slightly irregular in shape.

This irregular shape prevents light from focusing properly on the back of your eye, the retina. As a result, your vision may be blurred at all distances). A few surgeons have used this procedure to correct presbyopia (a vision condition in which the crystalline lens of your eye loses its flexibility, which makes it difficult for you to focus on close objects). This is a natural condition caused by aging and is usually experienced by people around the age of 40.

It is important to note that PRK and LASIK do not treat diseases of the eye like glaucoma or cataracts.

Recovery
In most cases, people return to work and normal activities within a couple of days. The protective layer of the eye takes about 3-5 days to heal, so it is important that the patient takes care during these recovery days.

Vision will be fine in about a day, although it will continue to fluctuate during the next couple of weeks. After the surgery, vision will be blurry or foggy. Patients will experience sensitivity to light. Knowing this, it is recommended that sunglasses be worn at all times.

Patients will usually be asked to not rub the eyes for two weeks. Swimming, makeup wearing, smoking or any activities that may cause foreign objects to come in contact with the eyes are also ill advised.
