Difference between Laser surgery and PRK Laser surgery


Lasik eye surgery hospitals in Delhi as well.

One of the most common types of laser surgery is LASIK surgery which stands for Laser-assisted in situ keratomileuses. The procedure is quite new and highly effective for patients suffering from myopia, hypermetropia and astigmatism. The surgical procedure involves the use of a corneal flap containing the epithelial as well as deeper stromal tissue. This is done with the help of a microkeratome or a femtosecond laser. The flap is lifted to expose the underlying tissues of the cornea which are then removed carefully to reshape the cornea, with the help of an excimer laser. The recovery period after laser-assisted in-situ keratomileusis technique is very short and the procedure is essentially painless.

PRK stands for photorefractive keratectomy and it is a type of refractive surgery that helps to correct refractive eye defects like Myopia (near-sightedness), hyperopia (far-sightedness) and astigmatism. The surgery involves the use of laser technology and was first conducted in the year 1986, approximately 13 years prior to the approval of Lasik Eye Surgery. Just like other laser based eye surgeries, photorefractive keratectomy involves the use of excimer laser to reshape the cornea and correct eye defects like nearsightedness, farsightedness and astigmatism. Unlike LASIK Eye surgery which involves the use of a flap to reshape the corners, photorefractive keratectomy involves the complete removal of the thin upper layer of the cornea, known as the epithelium. Since the use of flap is completely eliminated, so are the risks associated with it. Also, the risks of removing too much cornea are also greatly minimised. Custom PRK has also become quite popular nowadays. The technique helps your ophthalmic surgeon additional data regarding the requirements of your vision using customised wavefront technology. Although PRK surgery has a lot of benefits over LASIK Eye Surgery, however, there are certain disadvantages as well. The most highlighted disadvantage is that the recovery period following PRK treatment is quite longer than LASIK Eye Surgery. This happens because the epithelial cells need time to regenerate themselves. PRK surgery is highly recommended for patients having large pupils, dry eyes, and thin corneas.
