The clarity of our vision is dependent on the accurate focusing
of light rays upon the retina (the retina is the inner lining of
the back of the eye that is sensitive to light and on which the
photos of what we see are formed). But sometimes, because of an
imperfectly shaped eyeball, lens or cornea (the clear front portion
of the eye through which we see), the light rays do not focus accurately
on the retina, thereby resulting in improper vision. These focusing
errors are called ‘refractive errors’ and can be of
several types such as myopia (nearsightedness or minus errors),
hyperopia (farsightedness or plus errors) or astigmatism (distorted
vision or cylindrical errors ).
These errors can be corrected using non-surgical procedures like
glasses or contact lens or surgical procedures like Refractive Surgery.
What is Refractive Surgery?
Refractive Surgery is an eye surgery designed to
correct the refractive (focusing) error in the eye. The surgery
works by altering the shape of the cornea so that light rays can
be focused directly on the retina.
There are various surgical procedures like PRK (Photorefractive
Keratectomy), LASIK (Laser-Assisted In Situ keratomileusis) and
the latest Customised Lasik using wave front technology , LASEK
(Laser Epithelial Keratomileusis), Surface Ablations & Phakic
Intraocular Lens (IOL). However, different procedures are suitable
for different eyes and refractive errors . Contact us for more information
regarding the procedure best suited for your eyes.Whatever procedure
is adopted,it usually gives crystal clear vision post operatively.
Who is Eligible for Refractive Surgery?
All patients are thoroughly screened to assess their
eligibility for refractive surgery.The following basic criteria
should be met before contemplating refractive surgery.
• The number should be stable for at least one year.
• The patient must have sufficiently thick cornea for safe
treatment [this is measured pre operatively].
• The eye should be free from eye problems like macular degeneration,
cataract, proliferative diabetic retinopathy.
• Retinal examination should not reveal any abnormalityl.
How will Refractive Surgery benefit
you?
After Refractive Surgery, you can enjoy improved eyesight and no
or reduced dependency on contact lenses or glasses. This can definitely
be advantageous in several ways:
• Sharp and clear vision without glasses and contact lenses.
• If you are an athlete, swimmer or a sports person, improved
unaided vision can enhance your performance on
field.
• If you are a high myopic, you could be handicapped in an
emergency when caught without your glasses. This
unaided vision can ensure safety.
• Improves appearance and self esteem.
• Enhances lifestyle and career opportunities.
