Laser Eye Surgery
Laser eye
surgery can correct common vision problems. With
refined techniques and specialty equipment. These
procedures generally involves the reshaping of the
cornea to alter the way and place light enters the
eye. Results are usually favorable with these
procedures, however patients may not achieve the
perfect vision they want. In these cases, patients may
want to wear contact lenses or glasses. Even if
patients have worn contact lenses before the surgery,
they will require a new prescription and new fitting
due to changes in the eye. The new prescription may be
for soft or disposable contact lenses in a specialty
variety because of altered eye and cornea shape.

Photorefractive
Keratectomy
|
Photorefractive
Keratectomy or PRK is a recent eye surgery
development, where the shape of the cornea is
modified. Where the older procedures used the surgeons
scalpel to make cuts into the cornea of the eye, PKR
uses an excimer laser to sculpt the cornea.
The area covered by
the laser is approximately 5 - 9 millimeters in
diameter, and removes from 5 - 30% of the cornea
depth. By reducing the invasiveness of the procedure,
the practitioner can make very detailed changes to the
cornea, and there is little trauma to the cornea and
surrounding eye tissue.
Because of the
advancements in this laser sculpting technology, there
are other applications that can treat Myopia,
Hyperopia, and some types of Astigmatism.
Only your eye care
practitioner can help you decide is this surgery is
right for you. Your eye care professional can discuss
the benefits, and the safety and health risks,
involved in this and any other procedure.

LASIK
|
LASIK stands for
Laser-Assisted In Situ Keratomileusis. It is a
procedure that changes the shape of the patient cornea
using an excimer laser. This procedure can provide
permanent changes to the eye and therefore permanent
changes to vision.
In LASIK surgery, a
knife called a microkeratome is used to cut the
cornea. This cut produces a thin flap of cornea that
is 'hinged' on one side. The laser then removes a thin
layer of material under the flap, and the flap is
replaced and allowed to heal.
As with any surgery,
there are risks involved. Discuss this procedure with
your eye care professional if you have any questions.

Laser
Thermokeratoplasty
|
Laser Thermokeratoplasty
or LTK is a laser eye surgery for people with
Hyperopia or farsightedness. In this procedure, the
laser is used to heat small dot like areas on the
cornea. This causes the cornea to expand and reshape.
For these and other
eye surgery options, contact your eye care
practitioner.
