LASIK Introduction

The goal of any refractive surgical procedure is to reduce or eliminate the need for glasses or contact lenses

Did you know?


Dr. Epstein was the First Midwest Surgeon performing surgery for eye glass freedom. 


Three years later Dr. Epstein went on to be one of the five americans who brought keratomileusis to the U.S. and successfully practiced the procedure.

Common types of Refractive surgery


LASIK (Laser-Assisted In-Situ Keratomelusis) is a refractive procedure designed to reshape the cornea in order to eliminate or reduce a patient's need for corrective lenses such as glasses or contact lenses. In LASIK a thin hinged flap is created in the cornea using an instrument call a microkeratome. 


PRK (Photorefractive Keratectomy) is designed for the same purpose as LASIK. In PRK the epithelium of the cornea is removed over the area being treated. 


By middle age the ability to change focus from far to near diminishes greatly. Dr. Epstein has been performing procedures for freedom from bifocals and readers since 1997. There are several procedures done at the center to reverse symptoms of presbyopia. 

Freedom from Bifocals


With middle age comes eye trouble.  Often for the first time a person who has never before had to wear glasses finds the need to wear glasses to read and perhaps for full time wear. This condition is called presbyopia (from the Greek “presby” =old and “opia” =eyes). Now, the baby boomer generation can take some comfort in that surgical technology has provided a way out of reading glasses and bifocals.

What type of technology is used for Lasik

Wavefront Technology

The Center for Corrective Surgery is committed to providing the best and most up to date LASIK technology and because of this we have implemented the wavefront technology or the ability to actually perform customized LASIK, or simply custom LASIK. 

Wavefront Technology definition

 The VISX® WavePrint™ system is both a diagnostic and treatment approach that allows the doctor to take very precise measurement of the patient's eyes. 


My vision is extremely poor. Will LASIK work for me?

 The laser we use is the VISX Star S4. It is FDA approved to treat higher degrees of refractive error (very strong glass prescription.) It is possible that you may be able to have a good result with LASIK. The surgeon will take measurements of the thickness of your cornea as well as perform many other tests that will determine if laser surgery is right for you. Because the VISX laser is the most tissue sparing on the market we are able to treat higher degrees of nearsightedness than in the past. 

I wear bifocals. Can LaserVision eliminate my need for glasses?

 Using a technique called monovision, LASIK may greatly improve your reading vision. In monovision one eye is corrected for reading while the other eye is corrected (if needed) for distance. This would be attempted with contact lenses first to determine whether you would like this option. The second option would be correcting both eyes to see well for distance and using glasses when reading.

I am 18 years old. Can I have LASIK?

 The FDA guideline does allow for laser vision correction on patient over the age of 18. However, many people are still in a stage of growth at this age and there is a higher likelihood that your vision will change as well. Therefore, LaserVision will perform LASIK only on patients 21 and older.

How well will I see after the procedure?

 Most patients, 95% - 98%, see 20/40 (legal driving vision) or better after the procedure. Many patients, about 85%, see 20/20 or better.

How quickly will I be able to see?

 Most LASIK patients will be able to see more clearly the same day as the procedure, however the drops given after surgery will make vision cloudy for the first day.  Most LASIK patients see very well the next day after the procedure. You may notice continued improvements over the next several weeks.
