Are you a good candidate?

Why you should have refractive surgery?

All the refractive disorders that have been discussed – myopia, hyperopia, astigmatism, and presbyopia – can be corrected by prescription lenses. But many people dislike wearing glasses or contact lenses every day, and every year over one million people in the United States choose to have some type of refractive surgery.

Most of these people are tired of being dependent on glasses or contact lenses; aren’t you?

Some of them are contact lens intolerant, which means they can no longer wear contact lenses without irritating their eyes. There are many reasons to opt for refractive surgery, including the inconvenience of dealing with glasses or contact lenses. Your lifestyle will probably have the most influence on whether or not you decide to have this procedure. And more importantly those very active athletes and professionals are choosing Epi LASEK and LASEK because it gives them a competitive edge, on top of being 10x safer than LASIK.

All of the aforementioned Refractive disorders are treated by Dr. Chynn and his team at Park Avenue Laser Vision, through the use of their advanced surgical procedures and reliable equipment. Our newly-upgraded VISX laser with auto tracking technology is the best type of laser on the market and costs around $500,000! Dr. Chynn is the first ophthalmologist in New City who had LASIK himself. As a result of his experience, he can provide you with optimal care and the best treatment your money can buy.

What kind of tests will you need?

You should be prepared for thorough pre-operative testing. Dr. Chynn and his team will take you through a complimentary, comprehensive 9-point eye exam to make sure you are a good candidate for refractive surgery and to make sure you get the surgical procedure that is best suited for your eyes.

Here is a description of what you can expect:

Analysis of Old Prescription: We will “read” your old eyeglass prescription to make sure it is static and consistent.

Auto-Refractor (AR): This machine measures the degree of hyperopia, myopia, and/or astigmatism in your eyes using infrared technology.

Corneal Topographer: In this procedure, a computer creates an elevation map of your corneal surface. The main purpose of this test is to determine the frontal curvature of your eye and to ensure it is not warped. If you opt for the Wavefront procedure, an aberrometer is used to create a custom ablation profile prescription.

Slit-Lamp Examination (SLE): Also known as a biomicroscopy, this examination analyzes at the anterior (frontal) structures of your eye, including the eyelid, sclera, conjunctiva, iris, and cornea.

Tonometer: In this procedure, we use an instrument that measures the intraocular pressure of the eye to make sure you do not have glaucoma. The normal intraocular pressure ranges from 11-21 mmHg, or about 1/50th of the atmospheric pressure around you.

Introduction to Reading vizion: Simply put, mono vision is correcting one eye for seeing things close up, while correcting the other eye for seeing things that are far away. Your brain will figure out when to use which eye and this procedure may be useful for patients who want freedom from reading glasses at an older age.

Glare Testing: This simple test measures the extent of pre-operative glare that you normally see around bright objects. It will only be performed if you tell us that you have significant pre- operative glare symptoms. You can take this test again post-operatively to quantitatively measure if your glare has worsened or remained the same. Some patients are more sensitive to nighttime glare after surgery simply because they are more concerned about any aberrations in their vision; however, most do not experience a significant measurable change.

Dry Eye Syndrome: In order to test and diagnose for this, we will measure your tear production, evaporation rate, and quality of tear film. Oftentimes, artificial tears can correct this relatively minor problem.

Pupil size reading: This reading is performed in a darkened room with a simple instrument called a pupillometer that measures the diameter of your pupils. People with large pupils tend to have a greater degree of higher-order aberrations, and they may be good candidates for the Wavefront procedure (see Chapter 5). Our new WaveScan machine for the VISX Star S4 laser with an IR4 upgrade has a built-in pupil-measurement system, so we automatically perform this test on each and every patient, and adjust the diameter of the WaveFront treatment to match your pupil size if necessary.
