There are numerous options to LASIK surgery, such as PRK eye surgery. It would seem that the latter is safer and suffers fewer drawbacks than the more popular LASIK option. However, this is not entirely true and opinions vary from patient to patient. This article will attempt to clarify what PRK surgery is and whether or not you should choose this over the other options out there.
In case you didn’t know, PRK eye surgery stands for photorefractive keratectomy surgery. It is a surgery based purely on lasers and therefore avoids flap complications or mechanical errors done by the eye surgeon. The way it works is that an excimer laser, which is actually a chamber filled with argon and fluoride gas under high pressure and voltage, fires high energy radiation at the eye. The molecules in the eye absorb this radiation that cause it is break down. This process is called photoablation and when used in a controlled manner, it can accurately reshape the eye to reduce or completely eliminate one’s prescription, thus freeing you from having to wear glasses or contact lenses ophtalmologues Courbevoie.
As with all other laser based eye surgeries, PRK surgery also requires some time for it to correct your vision, since the cornea needs to heal itself. Sometimes, the surgery does not go as planned and the patient may be left with some persistent complications such as double vision, glare, haloes and even dry eyes. However, you should keep in regular contact with your doctor, should any of these symptoms get worse and to help avoid certain situations that can exacerbate them, such as strenuous exercise, applying make up or swimming in hot tubs.
It should also be noted that PRK eye surgery typically has longer recovery times than other eye surgeries and the experience of visual disturbances, as previously mentioned, can actually be more severe. Statistics show that only 42% of 97 cases had a uniform pattern of refractive power within the zone of ablation and 10% of these cases constantly complained of visual distortions, such as haloes, glare, starbursts, ghosting or double vision, that were severe enough to affect their vision overall.
As you can see, even though PRK surgery may be free from flap complications, since it is a purely laser based eye procedure, other complications that you would normally experience from other eye surgeries tend to be a little worse. Also, PRK surgery is not suitable for people of all kinds of prescriptions. While this is true for eye surgeries in general, PRK surgery is more limited. Studies have shown that those with high degrees of short-sightedness who undergo PRK surgery tend to regress to the point where the surgery was ineffective.
These factors just go to show that although PRK is a completely valid alternative to LASIK and other eye surgeries, you should take into account these limitations. If you are a suitable candidate for this kind of surgery, then I whole heartedness recommend you PRK. Of course, you should talk to your doctor before undergoing anything that would put your health at risk.
