LASIK Introduction

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

Meeting the Doctor & the Patient

Lets get to know a few things about Dr. Epstein and his LASIK experience!

LASIK Procedure

Watch Steve a Fire Fighter Paramedic have LASIK procedure done. 

Common Types of Refractive Procedures









LASIK (Laser-Assisted In-Situ Keratomelusis) is a refractive surgical procedure designed to reshape the cornea to reduce or eliminate the need for glasses or contact lenses. In LASIK, the operative eye is numbed with eye drops. Next, we use a highly accurate femtosecond laser (bladeless technique) to create a thin, hinged flap in the cornea. Then using a different device, called an excimer laser, thousands of tiny pulses sculpt the cornea without touching the corneal surface because the shaping takes place beneath the flap. After the excimer laser shaping has been completed, the corneal flap is fixed into normal position. The corneal flap initially remains in place due to the microscopic forces of the cells within the cornea. The initial stages of permanent healing start within hours.  


 PRK (Photorefractive Keratectomy) is designed for the same purpose as LASIK.  In PRK, the thin outer layer of the cornea (epithelium) is removed and discarded prior to reshaping the underlying corneal tissue with an excimer laser. The epithelium repairs itself (grows back over the corneal surface) within a few days after surgery. 

Freedom from Bifocals/ PresbyLASIK


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.
