Both PRK and laser eye surgeries aim at correcting certain defects
of vision that might otherwise affect our ability to see clearly and may even
lead to partial or total blindness. You can find the best LASIK & Laser Eye
Surgery hospital in Delhi which is equipped with all kinds of latest machines
and equipment that help to give very precise and satisfactory results. Both the
surgeries are offered by the best ophthalmic hospital in Delhi, India along with
various other procedures. Also, the services provided here are quite cheap and
at par with International standard. With the growth of the use of laser-based
technology for the treatment of various eye-related problems, there has been a
considerable increase in the number of refractive laser surgery hospitals in
Delhi. This has also led to the rise of many 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.
