LASIK and Vision Correction
Understanding Your Options
Are You a LASIK Candidate?
If you lead an active lifestyle and are bothered by the inconvenience or appearance of glasses and the risks of contact lenses, you may be a candidate for laser vision correction. Also, if allergies, dry eye, or other eye disorders make contact lenses too irritating to wear, laser vision correction may be a safe, convenient alternative.
Generally, you must be 18 years old and have healthy eyes without any significant change in your prescription over the past year.
For many of our patients, vision correction surgery is a life-changing experience. A dramatic improvement in vision takes place painlessly in just a few minutes. Many people wake up the morning after surgery and see the alarm clock clearly for the first time ever.

What is LASIK?
In this procedure, the surface layer of corneal tissue is folded back from its usual position. The laser then gently reshapes the surface, and the surface layer is placed back in its original position, where it bonds naturally. The procedure takes about five minutes.
Most patients say they have no pain with LASIK, and most can return to work the next day.
LASIK can treat nearsightedness, farsightedness, and astigmatism. With monovision or blended vision correction, LASIK can also correct Presbyopia.

CustomVue® Wavefront LASIK
The most exciting recent development in vision correction surgery is CustomVue (also known as "wavefront-guided) LASIK.
| Using WaveScan® based digital technology, originally developed for use in high-powered telescopes to reduce distortions when viewing distant objects in space, we can now identify, measure and correct imperfections in your eyes 25 times more precisely than with standard methods used for glasses and contact lenses. This information is transferred to the laser, allowing the surgeon to map and correct your eye's optical imperfections with microscopic detail.

Wavefront-guided surgery might be superior to traditional laser surgeries for many candidates. Custom LASIK is personalized for you, resulting in shaper, clearer vision and reduced risk of side effects such as glare, night vision difficulties, and halos which can sometimes occur following standard LASIK procedures.
An FDA clinical study showed the following results from patients 12 months after undergoing Custom LASIK:
• 100% could pass a driving test without glasses or contact lenses
• 98% could see 20/20 or better without glasses or contact lenses
• 70% could see better than 20/20 without glasses or contact lenses
Millions of people worldwide have successfully undergone laser refractive surgery, and the number continues to grow. The surgeons at Harvard Eye Associates find that for most patients, LASIK and Custom LASIK are the procedures of choice. However, you will be carefully evaluated during your consultation. If you have questions about Crystalens or other types of Laser Eye Surgery, we are sure to answer them. The LASIK surgeons at Harvard Eye Associates take pride in providing world class care to our Orange County California LASIK patients.

Other Options —
LASEK and PRK
These laser procedures are similar to LASIK, but the laser treatment is performed directly on the surface of the eye. Healing time is slightly longer than LASIK. Most people have normal vision after four or five days. These procedures are usually chosen for people whose corneal shape is not ideal for LASIK.

| Corneal Refractive Therapy (CRT)
CRT is an ideal option for people who are not a candidate for surgical vision correction because they are less than 18 years old or their vision is continuing to change. This technology corrects your vision while you sleep with safe therapeutic contact lenses.

Understanding Vision —
| |
Normal vision:
The cornea is able to bend light rays to focus directly onto your retina.
Both
near and far vision is satisfactory.
|
Light focuses at a single point on the retina.
(Move mouse over image.)
|
| |
Nearsightedness (myopia): The eye is too long (note the shape of the
cornea) and the focal point is in front of the retina.
Distant objects become
blurred, while near vision is usually satisfactory.
|
Light focuses at a point in front of the retina.
(Move mouse over image.)
|
| |
Farsightedness (hyperopia): The eye is short (note the shape of
the cornea) and the focal point is behind of the retina.
Distance vision
is typically satisfactory, with difficulty occurring at reading distance.
|
Light focuses at a point behind the retina.
(Move mouse over image.)
|
| |
Astigmatism: The astigmatic cornea is shaped
irregularly, like a football, having an oval rather than round curvature.
Light rays do not come to a single focus point, but rather objects are focused
at more than one point, distorting both distance and near vision.
|
Light focuses on more than one point.
(Move mouse over image.)
|
| |
Presbyopia: A natural part of the aging process, presbyopia occurs
when a person is unable to focus on near objects because of insufficient accommodation
ability.
Accommodation is the
ability of your natural (crystalline) lens to change from distance vision to
near vision as desired.
Presbyopia begins during the early to mid-forties, and manifests as an inability
to read without glasses.
|
Accommodation is the ability of the lens to
move between close
and distance vision.
