LASIK (laser assisted in-situ keratomileusis ) is probably the most commonly performed laser eye surgery procedure and tends to be what people think of when considering laser surgery for vision correction. However not all patients may be ideal candidates for LASIK surgery due to variations in cornea thickness and curvature. Photo refractive keratectomy ,or PRK, may be the better option for vision correction in some patients who are not able to have LASIK.
Prior to the introduction and subsequent popularity of LASIK, PRK was the most common refractive eye surgery procedure performed. Both LASIK and PRK share similarities in that an excimer laser is utilized to sculpt and reshape the cornea of the eye in accordance with the patients medical needs. Both techniques are used in the correction of myopia (nearsightedness), hyperopia (farsightedness), astigmatism (blurred vision resulting from corneal irregularity), or a combination thereof. Likewise, both are outpatient surgical procedures which may be performed in a physicians office or clinic setting. There are however a few differences in the two procedures.
In a LASIK procedure a small flap is cut with a special tool on the exterior of the cornea. The computer controlled excimer laser is then used to reshape the corneal tissue under the flap. The flap is then replaced over the cornea where it will adhere to the eye and serve to protect it. In PRK, the excimer laser is used to remove tissue and reshape the cornea directly on the surface, or epithelial layer, of the eye. A protective soft contact lens is usually placed over the eye for 3-5 days to allow the epithelial surface to heal.
Several major differences for the patient exist in the two procedures. The first is the recovery period, which tends to be considerable shorter for LASIK patients as opposed to PRK. Likewise, vision improvement with PRK tends to be more of a gradual process than take from a few days to a few months. LASIK patients will in most circumstances experience the benefits of their surgery in a much shorter frame.
A successful end result for both procedures is an improvement in vision, and the correction of pre-existing vision conditions. Only a thorough examination and consultation with a qualified laser eye surgeon can determine which is right for you.
Lasik Prk Eye Surgery
These procedures are expensive, and they do have some amount of risk and possible complications. Yet, thousands of people every year undergo these procedures and get rid of the constant use of glasses on contacts. So, when you consider going for this surgery, you need to consider the advantages this procedure will bring you, and weigh it against the risks.
The advantages of having a Lasik eye surgery are substantial. Here's a detailed description of them:
1. You will look better to most people. There are some people that glasses look good on them, but for most of us, glasses have a negative effect on our appearance. It makes us look in many cases older that our real age, and in makes us look like a "nerd" (even if we're not). Many models, actors, TV performers and other people who appear before an audience, used a Lasik surgery to get rid of their glasses. If you feel that you look better without glasses, you should consider the surgery. This is especially true for people who have a high number glasses. These glasses look even worse that the others, because of the glass thickness.
2. Save money. Glasses and contact lenses cost money. If fact, it's a considerable expanse. Let's do the math: a box of contact lenses costs about $20 and lasts for two weeks (hopefully). That's $40 a month, $480 a year. If you are wearing glasses, there are high one-time expenses every time you need to buy new glasses. A new pair of glasses may cost thousands of dollars. All these expenses can be avoided if you do the Lasik eye surgery. You'll become just like "ordinary" people who don't ware glasses. They don't have these expenses and therefore can use their money for other things.
3. Sports activities. Have you ever tries to run, plan ball games, swim, box, wrestle of do any other type of sports activity with your glasses or contacts on? If you did, than you already know that it's not the most comfortable experience. Glasses and contacts limit your movements and many people who ware glasses refrain from certain sports activities because of their glasses. Having the surgery will allow you to engage in any sports you would like to.
As you can see, I believe that the advantages of getting rid of glasses are huge compared to the minor risks of the surgery and the one time cost associated with it. If you think so too, you may want to start making enquiries about the clinics that perform this surgery near your place of resident.
