Today, LASIK (Laser Assisted in Situ
Keratomileusis) is the most commonly carried out laser eye surgery. This
surgery is primarily performed to treat myopia (nearsightedness), astigmatism
and hyperopia (farsightedness). Similar to other types of refractive surgery,
this process reshapes the cornea, so that light can enter the eye and can
properly focus onto the retina for a better vision. Experts opine that this
surgery, in most cases, is pain free and can be finished within 15 minutes for
both eyes. Results include enhanced vision without contact lenses or eyeglasses
and are generally seen in as little as 24 hours. There are several vision
correction surgeries available such as LASIK and PRK along with Phakic IOL
surgery, however, Lasik is most common and popular among people.
Execution
of LASIK Surgery
This surgery is performed by an expert or under
his guidance. During the procedure, the laser eye surgeon makes use of a microkeratome, which is a mechanical surgical
tool or a femtosecond laser to make a thin, circular flap in the cornea. The
next step includes the folding back of the hinged flap by the surgeon in order
to access the underlying cornea also known as the stroma and taking out some
corneal tissue using an excimer laser.
The laser which is highly specialized makes use
of a cool ultraviolet light beam to take out the microscopic amounts of tissue
from the cornea to reshape it, thus refocusing the light which enters the eye
for enhanced vision. Individuals suffering from myopia often aim to flatten the
cornea and those suffering from hyperopia aim for a steeper cornea. The excimer
lasers are also effective in correcting astigmatism by flattening an irregular
cornea into a more normal shape. Many people
have a certain misconception that LASIK cannot treat astigmatism. After
the cornea gets reshaped with the laser, the surgeon then puts the flap back in
place, and covers the area where the corneal tissue was taken out. The cornea
is then left to heal naturally. During this laser eye surgery India, the surgeon administers only topical anesthetic
drops as there is no need of stitches or bandages.
Protecting
Eyes from Sun after Lasik Eye Surgery
Many people would want to know what's the best
way to protect your eyes after laser
surgery in India. One of the best ways to recover from the surgery in the
long run is to look after your eyes properly. Many experts suggest to wear
sunglasses when you are in direct sunlight after the surgery. Doing this, you
can prevent the sunlight from coming into contact directly with your eyes,
something that's not at all recommended and can damage the cornea while it's
healing.
If you don't protect your eyes properly after
the surgery, then it can lead to Photokeratisis on a short term basis. In this
you can feel like having sand or grit in the eye and can be quite painful. You
can have it cleared easily by putting eye drops, however, more severe diseases
such as macular degeneration and cataracts can occur in the long term if eyes
aren't taken care of properly. Thus, experts suggest to wear quality sunglasses that offer
good protection when one goes outdoors. Best Lasik eye surgery India clinics suggest wearing sunglasses carrying
the 'CE' mark so that the patient can protect the eyes properly after the
surgery.
