Lasik
eye surgery is one of the most well known and safe methods of vision
correction, enabling people to get rid of their glasses and contact lenses.
There are several Lasik variants, including contoura vision, smile and
conventional lasik. The basic principle is reshaping of the cornea, to make
sure the rays of the light can entering eyes stay focused on the retina.
Reasons for Wearing Glasses
The cornea and the crystalline lens in the eye
are responsible for focusing on the light that enters the eye on to the
retina. Any problem in the structure,
especially curvature of the cornea, or in the length of the eyeball, simply
means that the vision is completely blurred.
In
myopia, the light rays focus before the retina, and in hypermetropia they focus
behind the retina. When it comes astigmatism, the light rays in various
meridians, focus on various locations.
When
it comes to correcting the retina, you will have to wear glasses or contact
lenses or go for contoura
lasik surgery which changes the focusing power of the cornea.
How does lasik eye
surgery work?
A
thin, circular corneal flap is raised using either a mechanized knife or
special laser. The laser then reshapes the corneal tissue, so that refractive
error is destroyed, and the light falls directly on the retina. The corneal
flap is repositioned. The results are perfect vision, without the need for
glasses or contact lenses.
What happens during
laser eye surgery?
During
surgery, the doctor uses anesthetic drops to numb the eye. So, you could feel
slight pressure during the procedure. The doctor will ask you to pay attention
to the light; your vision will be blur as the cornea is reshaped. You could be
asked to wear an eye patch after the surgery. Most doctors will see you after
an hour, before you can go home, along with how many times to use eye drops and
the precautions to be taken.
How does one know if
lasik eye surgery is good for them?
The
only way to know if you are the perfect candidate or not, for laser eye
surgery, even though it’s safe, is by visiting the doctor. To decide if you are
fit for the procedure, the doctor will conduct an eye examination that includes
a dilated retina check and talk to you about your options and what works best
for your eye health and vision needs. If you are not suitable for contoura lasik eye surgery, your doctor
will suggest other options for treatment to avoid wearing glasses or contact
lenses.
How are the various procedures
for spectacle removal different from each other?
Conventional Lasik and
SBK
Conventional
lasik and SBK is one of the most common vision correction procedures and under
such circumstances, the surgeon lifts a thin, circular corneal flap using a
knife and then a laser to remove the corneal substance called stroma to modify
the shape. The corneal flap is thinner
in SBK as compared to a conventional lasik. It offers patients safety and
efficacy and can be given to patients with thin corneas as well.
Relex Smile
In
smile lasik in Delhi, no corneal flap is lifted. On the contrary, a small
incision is made on the corneal surface, to remove the corneal lenticule from
the stroma, to change the corneal shape and power. It causes no dryness of the
eye, no side effects but the vision could take a few days to stabilize.
Contoura Lasik
Contoura
lasik is another technology for vision correction and uses the best algorithm
to capture points on the surface of the cornea.
Several patients who have undergone contoura
lasik surgery have gotten perfect vision.
The
ablation and reshaping of the cornea in contoura vision is adjusted to your
eyes and checks each cornea to create the best results, with no side effects
like halos and glare.
