What is an Excimer Laser Procedure? |
The front of the eye, or cornea is reshaped with a very short wavelength of light energy. The laser flattens
or steepens the cornea by ablating tissue. To reshape the cornea, only a
minimal amount of tissue is removed, normally less than 10% of the cornea.
The surrounding tissue is not disturbed during the procedure.

 |
How Long has the Procedure Been Done?
| The procedure has been actively done since 1988 in many countries. Over 500,000
procedures have been performed in the United Kingdom, France, Germany, Sweden, Belgium, Korea, Japan, Australia, China,
and many other countries. The USA core studies include 2,500 patients over the past 6 years prior to submitting data to FDA
resulting in approval. This occurred on October 20, 1995, as safe and effective. Utica, New York was 1st in Central New York to
begin treatment in November 1995.

 |
How Much Does the Procedure Cost?
| The fee for the procedure
starts at $1995 for both eyes and increases with complexity of your
prescription.. The procedure is considered functional, and is not covered by most medical plans. It is
deductible as a medical expense for tax purposes. Loans can be arranged with local Banks.
No interest is available with some of our surgical programs. Ask our
office staff for particulars.

Will I Become Nearsighted Again?
| The procedure is a permanent correction, once the cornea is reshaped tissue
will not regenerate. Studies have shown there is little if any regression once healing is completed, three to six months after the
procedure. A prerequisite to be considered a good candidate is a stable prescription. i.e., less than one diopter change over
the course of a year (FDA). If you undergo the procedure when your prescription is unstable you may regress from your desired
result. Must be 21 years old or older. Our eldest, happy patient was 73 years old (12/19/95) and of course a sassy Lady!

 |
What are the Long Term Risks?
| As with any procedure there are risks and potential complications. There is data on
surface ablation patients out to sixteen (16) years, (i.e., 1989) this data
supports stable results with little if any regression. No one can say what
will occur in twenty years, however experts feel confident nothing will
change over the long term. This confidence is based on a decade of study
with the Excimer laser, and a century of continue research on corneal wound
healing.

Will the Procedure Help Me?
| The vast majority of people who are myopic (nearsighted) and/or astigmatic are
eligible for the procedure. Someone who is myopic can see well close up, but has difficulty seeing clearly in the distance. A
myopic eye is either too long for it's focusing power or the cornea is too steep. The astigmatic eye is an irregular curvature of the
eye resulting in more than one focal point, preventing a sharp point of focus on the retina. As an example, a normal eye is shaped
like a tennis ball (spherical), while an astigmatic eye is shaped like a football (toric).

 |
Will it Hurt?
| The procedure itself is virtually painless. The majority of patients will experience
irritation in the 12-24 hours immediately following the procedure. Some will experience no irritation or discomfort, others will experience
varying degrees of moderate to severe discomfort.
|
 |
 |
Why Will it Hurt?
| The outer layer of skin protecting the cornea, the epithelium, must be removed during
the procedure. Contact lens wearers often tear or scratch the epithelium while inserting and removing their lenses. The resulting
sensation for contact lens wearers and Excimer laser patients is a scratchy, burning sensation.
|
 |
 |
What about Infection?
| The risk of infection is present from the time of the procedure until the epithelium
regenerates. In a normal healing process this will take between 24 and 72 hours. During that time the patient is fitted with a bandage
contact lens, placed on anti-inflammatory drops, and monitored at 24 hour intervals.
|
 |
 |
How is the Discomfort Controlled?
| The patient will use a combination of drops as well as a bandage contact lens to control
the discomfort. Tylenol 3 or it's equivalent is also prescribed, although much less than half the patients treated will require it. Also,
non-steroid anti-inflammatory drops are an adjunct topical medication.
|
 |
 |
Do I Need to Take Time off Work?
| Most patients return to work three days after the procedure. Normal activities including
sports may resumed at this time. However, swimming and gardening should be avoided until at least a week following the procedure.
You may begin driving the next day.

 |
What About Presbyopia (The Need For Reading Glasses)?
| Presbyopia is a normal aging process that causes a hardening of the lens. The Excimer
laser treats the corneal surface only, but can compensate for Presbyopia. Please ask the ophthalmologist and your eye care affiliate
who performs the screening for a full explanation.
|
 |
 |
What Are Other Risks Associated With Procedure?
| Other risks associated with
surface ablation are Haze, Overcorrection, and Undercorrection. A full
explanation of these potential risks will be explained during the screening process. They are all treatable by an enhancement procedure.
A superficial corneal haze, considered as part of the healing process, may be evident through slit lamp examination initially, but normally
dissipates in the 6-8 weeks following the procedure. Persistent haze, rare in its occurrence, can be successfully resolved with a
retreatment. Undercorrection, which may be a planned course of treatment,
or may be caused by an unusual healing process can also be successfully
retreated in order to eliminate the residual refractive error.
Overcorrection is a risk, however slight.

 |
What are the Benefits?
| Every individual who undergoes the procedure is motivated by what they perceive as their
own benefits. Participation in sports and leisure activities without the hassles of corrective lenses or glasses is motivation for some.
Others would like to see the alarm clock in the morning without putting on their glasses. Whatever the reason, the vast majority of patients
who have undergone the procedure at Dove Laser are satisfied with their result. Many of our patients are interested in long term
investment in their future such as law Enforcement Career. Many of the Oneida Indian Nation Employees (Dealers, Security) are
laser vision correction
patients.
