PRK Eye Surgery
 PRK eye surgery - photorefractive keratotomy - is a type of laser eye surgery, used to correct mild to moderate myopia, hyperopia, and/or astigmatism. Like all other laser eye surgery procedures, photorefractive keratotomy also reshapes the cornea in order to enable the light rays to focus at retina. Unlike LASIK, PRK uses a cool pulsing beam of ultraviolet light on the surface of the cornea, and not underneath it.  Photorefractive keratotomy is a highly accurate system of treating vision problems, especially myopia.  Limitations of PRK eye surgery:
Side-effects of PRK eye surgery:
 The PRK eye surgery procedure is done under local anesthesia. It takes around 10 minutes to do both the eyes. Of course a previous evaluation of the eye as well as eye- measurements must have already been done! During PRK eye surgery, the surgeon uses a laser of cool pulsing beam of ultraviolet light to reshape the cornea. Reshaping is done on the surface of the cornea, and not underneath it as in LASIK. After the PRK eye surgery, a bandage contact lens is worn for the first 3 to 4 days to allow the surface of the eye to heal. Once the surface gets healed, it is removed. Results are not immediate. The vision keeps swinging between the clear and the blurry for quite a few weeks after PRK eye surgery.  It's only after a few months that the vision stabilizes and gets set to it's best within the limitations of PRK eye surgery procedure. Dry eye after surgery is a rule rather than a possibility and prescription eye drops must be used to prevent infection and keep the eyes moist. PRK eye surgery procedure is not used to correct presbyopia. Pregnant women should not have laser eye surgery of any kind because the refraction of the eye may change during pregnancy. But my arguement starts from this point only, further: The last point in the above discussion says: Pregnant women should not have laser eye surgery of any kind because the refraction of the eye may change during pregnancy. Why? Why and how can the refraction of the eye change during pregnancy? May have something to do with the postural changes in the body during pregnancy! Whatelse otherwise? And what, in fact, does the laser eye surgery do to the eye? Let us see: Cornea is the front most transparent part of the eye that plays its part-role in bending the rays of light falling on the eye in order to focus them at fovea on retina. If, for whatever reason, the said rays of light fail to focus on retina but do so rather short of it (myopia), behind it (hyperopia and presbyopia) or more so in one meridian and less so in another (astigmatism); a change in the shape of cornea will be able to correct the fault exactly the same way as is done by eyeglasses or contact lenses placed (as they are!) just in front of cornea. In other words, laser eye surgery including PRK eye surgery and LASIK, changes cornea to permanent eyeglasses or contact lenses inside the eye rather than in front of it. Can this be called a treatment? Or is it just a kind of management exactly like the one done by eyeglasses or contact lenses? Only that the inconvenience of wearing eyeglasses on, or putting contact lenses in the eyes has been eased off! What has been the real cause of the problem? Is it the shape of the cornea, the shape of the lens or the shape of the eyeball? We must be very clear about it. If it is the shape, anyway, of anything, what does it mean when the diopter number of the eye increases? Does the shape change? What else, otherwise? If yes, that means the shape is technically able to change. And if the shape can change to increase the diopter number, it ought to be able to change in a way that decreases the diopter number as well! Then why do we change it the surgical way? Simply because we don't know how to change it non-surgically! Change what? The shape! Of? The cornea, the lens, or the eyeball? Whatever, but we don't know how. But it does change of its own. And it does so after the surgery too! What shall we do then? I personally came across numerous such cases as had been passed as successful and remained so till around eight years after the laser eye surgery but then rolled back to the same old number that was there before the surgery was done. The diopter number is the same again but the structure of the eye has gone deformed! What shall we do now? Again scrap the cornea further? How long shall we go on doing that? Why are we going on deforming the structure of the eye? We don't know when and why the shape again starts changing of its own. All our surgical changes, then, will not only go useless but may prove to be harmful too in the long run. Why does the shape change, and shape of what? Is it the cornea, or the lens or the eyeball? Not cornea. It doesn't have the musculature. Lens certainly does but temporarily and dynamically, according to the need of the moment (not the hour!). Only the eyeball is left. And it can. It has the musculature to do so. So it's the eyeball that can change its shape and give the eye a diopter number! Even after laser eye surgery! Or it can change the other way round and free the eye of its diopter number without the laser eye surgery! But not after laser eye surgery. It is bound to keep itself deformed - and only to a particular extent set by the surgery, neither less nor more - in order to see clear because it is permanently wearing the surgical lenses that the cornea has been permanently changed to. Any deviation in any direction, and the eyesight will get the grunt of it. And it does! The eyeball does keep changing the shape in the normal course of events. It's a dynamic and not a static structure. But after the laser eye surgery, it is forced to keep itself static - in a deformed shape - just like a bespectacled eye is. Unluckily, keeping the eyeball statically deformed is a continuous stress to the eye, to the body and to the mind. Is there a way (of course non-surgical!) to change the shape of this statically deformed eyeball and turn it dynamically natural? Immediately? So that the humanity may get rid of eyeglasses, contact lenses and the most importantly the laser eye surgery menace! Vision therapy seems to do the job through opening the third eye; and that too, opening it instantaneously. If it is really so, it must, at least, be given a try before going for the laser eye surgery and causing a permanent deformity in the structure of the eye which can never be undone too!
