Your Exam: What are Refraction and Dilation?
is performing a series of measurements, both with a computer and/or
using trial lenses in front of the eye, in order to determine your
best possible vision. This is important in ensuring that any decrease
in vision is not due to a medical problem which may require
treatment. It is also used to determine the prescription necessary
for glasses or contact lenses.
usually lasts 3-4 hours, sometimes longer for people with light
colored eyes. When the use of stronger drops is necessary, as in
children, the effect may last for a day or longer.

cataract surgery be done with lasers?
experimental laser technology is being developed to aid in cataract
surgery, traditional surgical techniques are still required when
using these devices. Lasers alone cannot be used to remove a
cataract. Typically, a form of ultrasonic technology, called
phacoemulsification, is used to perform today's high-tech cataract
surgery with intraocular lens implantation. We routinely do use
lasers in our office for treatment of glaucoma, retinal diseases and
laser vision correction.
which stands for Laser-Assisted In-situ Keratomileusis, is a type of
refractive surgery used to correct myopia, hyperopia and astigmatism
and is used as an alternative to contact lenses and glasses.
The procedure involves creating a thin flap on the surface of the eye
and folding it back to allow for the remodeling of the corneal tissue
by the laser. The flap is then repositioned and the eye heals
after the surgery is completed.
has significantly advanced over the past ten years. Today, safety,
accuracy and precision of the procedure has been greatly enhanced due
to the use of 3-D Eye Tracking, Wavefront CustomVue technology, IRIS
Registration and the Pentacam HR system.
is a prime candidate for LASIK?
candidates for LASIK are:
over 21 years of age.
who maintain the same eye prescription for at least a year.
who possess no pre-existing corneal abnormalities or other medical
with realistic expectations regarding the results of laser vision
who are not pregnant.
by having a complete eye evaluation can an ophthalmologist tell you
if LASIK is an appropriate, safe procedure for you.
is also performed using the excimer beam. Rather than creating
a flap on the cornea, the cornea is gently brushed to remove the very
superficial corneal cells. The laser is then applied to the
underlying tissue. Over the next week or so the superficial
cells that were removed grow back to cover the surface. Many
surgeons prefer PRK for patients with larger pupils or thin corneas,
enabling us to treat patients who would not be good candidates for
LASIK. At Hudson Valley Eye Surgeons, PC, we are able to custom
design the correct procedure for each patient, rather than a "one
size fits all" philosophy.
there pain associated with LASIK?
if any, is minimal with LASIK. Numbing eye drops are applied to
the eye prior to the procedure. Some mild pressure is felt on
the eye while creating the corneal flap, however, the actual cutting
of the flap as well as the laser treatment is pain-free. Some
patients may experience mild to moderate irritation for a few hours
after the procedure.
I be able to see clearly immediately after LASIK?
you may be able to see with sharper focus immediately after LASIK,
eye drops used during and after your surgery are necessary to heal
the cornea. While a dramatic change in vision is experienced as
soon as the following day, the eye continues to heal over the coming
weeks and the vision continues to become even more crisp during this
I have 20/20 vision after LASIK?
everyone's eyes are different and may heal differently, not all
patients will experience 20/20 vision after LASIK surgery.
long will the effect of the Laser last?
the healing process has finished, the effect usually remains for
life. In some instances, however, a retreatment may be required.
some patients need glasses after surgery?
with very strong prescriptions may not achieve their full correction
with laser alone, and glasses or contact lenses may be necessary in
certain situations. For patients close to (or over) 40 years of age,
reading glasses may be necessary.
laser do you use and should I wait until a newer generation of lasers
use the VISX Star S4. This laser is a variable spot-scanning laser,
which means that it optimizes the balance between speed and precision
that all lasers attempt to achieve. It is fitted with an eye tracker,
which corrects for any fluctuations in eye movements. The S4, with
3-D Eye Tracker and Iris Registration, is the latest in the VISX Star
laser series, which is the most widely-tested and used laser system
in the U.S. We have a laser technician and a laser engineer present
during every procedure to assure perfect functioning of the laser,
with standard re-calibrations between procedures.
current laser is a 4th-generation laser. The S4 is fully
wavefront-compatible, allowing us not only to free patients from
glasses and contact lenses, but also to correct even minor
abnormalities in the optical systems of selected patients.
insurance cover laser vision correction? Do Employers Cover It?
How much does it cost?
health insurance plans will not cover the cost of laser vision
correction, although a few are now beginning to do so. However,
employers will often help patients to cover the cost of this surgery
through pre-tax salary deductions using Flexible Spending Accounts
and Cafeteria Plans. When compared to the cost of glasses or contact
lenses over several years, laser vision correction can actually end
up saving you money. Laser Vision Correction does qualify as a
medical deduction if you can take a medical deduction. (See IRS
Publication 502 for more information.)
you have a "Vision Care Rider" on your health insurance,
the cost of a refraction is specifically excluded from payment by the
insurance company, much as cosmetic surgery is excluded.
Medicare does not cover preventative medical care, in general, it
also does not cover for "routine eye exams," or "screening
visual field" testing. If, however, you are found to have a
medical problem during your "routine eye exam" or on your
visual field test, they will cover for treatment of that problem on
future exams. Many other insurance carriers follow Medicare's
