| Wave
Front Lasik |
| Wave Front Lasik is a unique
corneal mapping technique that creates a
three dimensional map of your cornea. Using
a sophisticated system of light refraction,
the Wave Front device creates a comprehensive
`map' of all your eye characteristics, abnormalities
or irregularities. This includes the most
fractional (saccadic) of eye movements.
For the Lasik procedure to be really precise
it is important to detect these movements
and incorporate them during application
of the laser beam.
The laser radar tracking system developed
by NASA's "Strategic defense system"
tracks thousands of readings per second.
This data is then transmitted to the laser
in such a way that it can be locked on
to a fixed point on the cornea irrespective
of movements in the eye, thereby ensuring
100 percent accuracy. This technique leaves
absolutely no scope for error and the
chances of your regaining 20/20 vision
is guaranteed.
Wave Front Lasik is the perfect solution
for curing astigmatism, near-sightedness,
far-sightedness and presbyopia (a condition
that is caused by the ageing of the lens
resulting in loss of flexibility).

| Aspheric
Wave Front Lasik |
| Aspheric Wave Front Lasik
is one of the most advanced procedures for
vision correction in the world today. This
procedure is not merely about correcting
your vision but endowing you with a visual
sharpness and clarity that far exceeds conventional
vision aids like spectacles or contact lenses,
and conventional Lasik.
Typically, the term ``Aspheric'' means
``not sphere-shaped''. Simply put, in
the Aspheric Wave Front Lasik procedure,
after the Wave Front device provides the
requisite data, the cornea is shaped in
such a way that the polar diameter (prolate)
is higher than the peripheral diameter
(oblate). This prolate shape helps the
eye in gaining practically high-definition
vision and enhanced night vision capability,
while completely eliminating any optical
side-effects like spherical aberrations.
Wondering what life would be after Aspheric
Wave Front Lasik? You will no longer require
glasses or cumbersome contact lenses for
ever. And what's more - you get a vision
clarity that is more than 20/20! Contact
us today because it really can change
the way you look at life and the world
around you!

| Plano
Lasik (Conventional) |
| The term LASIK is derived
from Laser-assisted Intrastromal Keratoplasty.
Today, Conventional Lasik surgery is the
most common procedure for vision correction
in cases of astigmatism, near- and far-sightedness.
Lasik surgery involves cutting a corneal
eyeflap and involves using a specially
tuned laser to burn the surface of the
eye until it matches the predefined shape
set out by the eye surgeon. After the
reshaping is done, the original flap is
replaced. The beauty of this procedure
is that the laser does not touch any of
the nerves where the burning takes place
and hence it is completely painless.
MediTours-affiliated Eye Care Centers
use the Excimer laser which unlike other
lasers do not cause thermal (heat effects)
but acts by breaking the intermolecular
bonds at the tissue level of your eyes.
This vaporizes only those specific tissues
where it is being focused. This unique
ability of this laser makes it ideal to
reshape the corneal tissue. Vision correction
is achieved by these lasers is due to
generalized correction of the shape of
the cornea.
The whole procedure is quick and usually
lasts for 15 to 20 minutes. Since it is
completely painless with minimal discomfort,
you can leave after a short while and
rest for the day.

| Cataract
Surgery |
| The eye works like a camera
where in the lens of the camera focuses
the light on to the film, similarly the
natural lens of the eye focuses light on
the retina of the eye. Cataract is caused
by clouding of this natural lens of the
eye.
This clouding of the lens results in
blurring of vision, making routine active
like reading, driving, etc., difficult.
Typically, cataracts are a part of the
natural ageing process. However, it can
also occur due to eye injuries, kidney
disease, diabetes, etc.
There is no medicine, eye drop or exercise
to cure cataract. The only treatment available
for cataract is surgery. Modern surgery
involves removing the cataractous (cloudy)
lens and implanting a synthetic lens (IOL)
within the eye. This lens is permanent
and provides natural vision. Cataract
Surgery is amongst the most commonly performed
surgeries all over the world and millions
of patients have undergone the procedure.
Traditionally this surgery required a
cut in the eye 10 to 12mm wide which required
stitches. This resulted in a number of
restrictions after the surgery. However,
that is not the case any more!

| PHACO
Emulsification: Quick and Painless |
| MediTours-affiliated Eye
care Centers are pioneers in the field of
Topical PHACO Emulsification (cataract surgery
with drop anesthesia) in the country. This
procedure is also known as injection-less,
stitch-less and bandage-less cataract surgery.
The PHACO Emulsification technique involves
performing the surgery through a small
valve 1.6 to 2.8 mm in size.
A computer-controlled ultra fine instrument
is inserted to break the cataract into
small pieces and then removed by suction.
After the cataract is completely removed,
a clear synthetic lens (IOL) is inserted
in the eye through the valve using an
injector system. This valve does not require
any stitches and seals on its own immediately
after the surgery.

| Benefits
|
|
The whole procedure lasts for about 15
to 20 minutes and visual recovery often
starts within a few minutes. The vision
recovery process is complete within a
day or two as compared to traditional
surgery where total visual recovery is
achieved in 6 to 8 weeks
This surgery also minimizes the need
for spectacles after surgery due to lesser
induced cylindrical power
The patient can resume most of the daily
routine activities like watching TV, bathing
driving, cooking etc. the same day without
any restrictions whatsoever.

| Glaucoma
Surgery |
Glaucoma is an eye disease
in which the normal fluid pressure inside
the eyes rises gradually, leading to vision
loss - or even blindness.
There are two basic types of Glaucoma -
open-angle and narrow-angle (or angle-closure)
glaucoma. Open-angle is the most common
form, accounting for 90% of all cases and
is associated with aging. When a person
ages, the eyes' drainage apparatus may not
work as effectively as it should. In narrow-angle
glaucoma, the eye pressure is normal until
the drainage angle becomes suddenly blocked.
Eye pressure rises abruptly to dangerous
levels. Immediate treatment is necessary.
Increased eye pressure means you are at
risk for glaucoma, but does not mean you
have the disease. Glaucoma can develop even
without increased eye pressure
So how do you know if you have Glaucoma?
At first, open-angle glaucoma has no symptoms.
It causes no pain. Vision stays normal.
As glaucoma remains untreated, people may
miss objects to the side and out of the
corner of their eye. |
| |
| Detection |
| There are many tests that
can be conducted by your doctor or eye care
professional to detect glaucoma. Usually
intraocular pressure tests and visual field
tests are performed in combination to determine
the eye's pressure and the pressure's affect
on the optic nerve. Photographs of the optic
nerve may also be taken to determine its
health. These simple tests can ensure that
the disease is diagnosed early, so it can
be treated before permanent damage is caused. |

| |
| Treatment |
| There is no cure for glaucoma.
Damage done to the optic nerve is permanent.
There are, however, many treatment options
that can minimize the effect and prevent
further damage. Treatments include eye drops,
laser trabeculoplasty, or conventional surgery.
These treatments are often done simultaneously.
Majority of patients are managed by simple
eye drops alone. There are plenty of combinations
of these available and your eye doctor
decides what is best for you. Medication
can be used to reduce eye pressure thereby
preventing further damage to the optic
nerve. Eye drops are the most common type
of medication for this condition. Tablets
may also be prescribed.
Laser trabeculoplasty is a treatment performed
by a doctor or eye care professional.
A laser machine is used to improve the
drainage in the eye. This is a longer-term
solution than medication, but the effect
will reduce over time.

|
|
| • |
Selective Laser Trabeculoplasty
(SLT) |

|
Laser treatment for Glaucoma
In conventional surgery, a small piece of
tissue is removed from the eye, which creates
a new opening for the fluid to leave the
eye. |

| Squint
Removal |
| Squint eyes - medically termed
as strabismus - occurs predominantly in
infants. Strabismus is basically a condition
when the muscles that control our eye movements
are not synchronized or balanced. Our eyes
have six muscles attached to them in order
to control eye movement. Two muscles coordinate
the sideways movement of the eye - say from
left to right or vice-versa. The four remaining
muscles facilitate the vertical and tilting
movements of the eye - typically up or down.
In order for the eyes to absorb any image
and transmit the same to the brain, the
muscles of both the eyes much work in
perfect balance and synchronization. A
misalignment of the muscles of any kind
results in strabismus which affects normal
binocular vision and loss of depth-perception.
There are two types of strabismus - Esotropia
(where the eyes turn inwards) and Exotropia
(where the eyes are turned outwards).
Both these conditions can be corrected
to a large extent through strabismus surgery,
although achieving a perfect balance and
alignment may not always be possible.
Parents of children must also be prepared
to accept the fact that correction of
strabismus may require more than one or
two surgical procedures.
However, if detected and treated at the
right time, almost normal vision can be
restored, along with the ``cosmetic''
appearance of the eyes. Any shortfall
can be further corrected with the use
of spectacles and special lenses called
``prisms''. More importantly, the child
is spared the psychological trauma of
having to live with crossed eyes.
|
| |
| Procedure |
| The principle behind strabismus
surgery is to adjust the tension in the
muscles that control the eyes. Based on
which of the two cases of strabismus is
applicable, a small incision is made in
the tissues of an eye (or both eyes, depending
upon the severity of the condition) in order
to reach the eye muscles controlling it.
In the case of esotropia, these muscles
are pulled further inwards thereby allowing
the eyes to straighten. In some cases the
length of the outer muscles are shortened
which helps in pulling the eyes further
outward.
Strabismus surgery is safe, quick and
the preferred procedure for the condition.
Recovery time is rapid and patients can
return to their normal life and activities
within a few days time.
