Demand. Any open market procedure or product is subject to pricing differences based upon what the public perceives. Prk started out expensive and got less so when many machines were set up for the procedure. Due to the economy, many of these are now closed and the remainder can charge more. They will lower their prices when their waiting rooms empty out.
It isn't. I guess it depends on what you mean by expensive. Considering the benefits you stand to gain from enjoying life much less dependent on glasses or contacts; and the savings from not having to buy glasses, contacts, etc., many people consider prk a very good value. Most of my patients are thrilled with their new vision and think the surgery was well worth the money they spent.
Less than LASIK. Prk was very common at one time, because a flap in the cornea was not required. Now with custom ablations, lasik, lasek and other types of refractive surgeries, it is used less commonly. It still has a place in patients with certain types of corneal disorders where a flap might cause a problem with healing, or if the ocular surface would benefit from the prk. Please discuss with your eyemd.
Relatively common. Prk is second only to lasik as the most common corneal treatment for nearsightedness, farsightedness and astigmatism. Both procedures use a laser to reshape the cornea. In lasik, a flap is first made and the laser is applied under it, while in prk laser is applied directly to the front of the cornea after removing the surface skin. Lasik is more comfortable and one heals more quickly from it.
A few. Possible disadvantages for prk (as compared to lasik) include longer healing time (weeks), more significant pain, need for stronger pain meds, corneal haze or scarring, and dry eyes. There are other risks for any laser refractive surgery.
PRK. First it is determined if you are a good candidate for the procedure. Prk is done with eye drop anesthesia. You recline in a chair similar to a dentist chair, and an instrument is placed to hold the eyelids open. You look upward toward the laser opening. The surgeon checks the positioning, settings, and alignment, and proceeds with treatment. A bandage contact lens may be placed for comfort.
PRK. This is one of the two major methods of laser refractive surgery to correct eyeglass needs. Lasik involves making a corneal flap and sculpting the inner corneal tissue into a new lens. Prk directly cuts through all layers to sculpt the new lens. Both produce essentiallly the same end result but lasik is more comfortable for a week or so compared to prk. Prk is possible for some thinners eyes.
PRK Info. Prk (photorefractive keratectomy) is a traditional way of treating refractive errors, and has been used by doctors all over the world. During a prk procedure, tissue will be removed from the surface of your cornea and reshape the cornea according to your refractive error. This is all accomplished using the state-of-the-art visx excimer laser.
Many criteria. There are many criteria that establish candidacy for any refractive surgery. The prescription, the corneal thickness and curvature and the overall health of the eye are some of these. A consultation with an experienced surgeon is the best way to determine whether you are a candidate for vision correction surgery and which procedure is best for you.
Ophthalmologist. Many ophthalmologists in your area will offer this procedure if you are interested in being less dependant on glasses. Look for practices that offer LASIK, they can also perform PRK. They will evaluate you and let you know if you qualify for PRK. Good luck.
Depends. Prk over lasik is utilized when the lasik was performed more than 3 years previous and the patients has a significant residual prescription limiting their uncorrected vision.
PRK vs LASIK. Both prk and lasik can be used to improve vision. Both are equally effective. However, some patients with specific corneal conditions are not candidates for lasik, but can be candidates for prk.
Lasik and PRK. Various diagnostic test should be done in order to see if a person is the right candidate for either lasik or prk. Depending on a person's corneal thickness and corneal shape, these should be taken into consideration when deciding which procedure to do.
Get the one. The doctor recommends. Both are safe. If the doctor is leaving the decision to you, get another opinion.
