Dr Nicholas Caro Answers Frequently Asked
Refractive Surgery Questions


What is LASIK?
LASIK is designed to correct myopia (nearsightedness), astigmatism and in some cases, hyperopia (farsightedness). During the procedure, a special instrument creates a flap in the cornea. A laser is used to reshape the interior of the cornea and then the flap is moved back in place.

I have astigmatism and myopia. Can both be corrected?
Yes, in most cases astigmatism and myopia can be eliminated using two procedures. One procedure will flatten the cornea, while the other will bring it to a more rounded shape.

I’m farsighted, can corrective eye surgery help me?
Currently, methods are available using the laser to correct hyperopia (farsighted vision). However, our doctor must evaluate whether you are a candidate for this new procedure.

What is the success rate?
Depending on your prescription, our doctor can determine the likelihood of reaching 20/40 or better vision. About 95% of our patients reach 20/40 or better vision. This means you can drive without a restriction.

Which laser do you use?
After researching the different lasers available, Dr. Caro only uses the computer-guided Nidek EC5000 Scanning Laser to reshape the cornea and correct vision. He was the first physician in the Chicago area to acquire the iTrace tracking system for measuring refraction. This system allows him to create a customized LASIK procedure for each patient and when used with the Nidek laser provides patients with reliable, consistent results.

Why can't corrective eye surgery eliminate the need for reading glasses?
Aging causes presbyopia or the need for reading glasses. As you age, the eye lens loses its elasticity resulting in a need for reading glasses usually between the ages of 40-45. Presently the only alternative to reading glasses is monovision.

What is monovision?
In a monovision correction, your dominant eye is corrected for distance, and your non-dominant eye is corrected for reading or intermediate vision. Monovision does not work for everyone so it is always best to first try monovision using contact lenses. If it does work, you generally can function without glasses for most distance. However, some individuals want "night driving" glasses or "sewing" glasses. Many will eventually need reading glasses as they continue to age.

Is this procedure covered by insurance?
Most insurance companies do not cover corrective eye surgery because it is considered a cosmetic procedure. However, there are a few that do and our staff will be happy to check with your carrier.

Does corrective surgery hurt?
No, numbing drops are used to eliminate any chance of pain. The whole procedure takes only a few minutes.

How long will the correction last?
The correction is designed to last the rest of your life. However, you may need reading glasses sometime after the age of 40.

I've heard it takes six months to improve my vision.
Fluctuation can occur, but visual improvement is almost immediate following surgery. The degree of your corrective determines how long your vision may fluctuate but most patients see anywhere from 75 to 95% better the next day.

How do I know if I am a good candidate?

After a complimentary evaluation, one of our doctors will be able to determine whether your vision is correctable. The evaluation includes a regular eye examination and a medical history.

Do you offer financing?
Yes, we have several excellent financing options that include no interest down for those who qualify. Our office staff will be happy to help you decide which one is better for you. Also, don’t forget to check with your employer because some companies pay part of the cost of corrective eye surgery. You also may use your company flex plan.

What laser does the center use and why?
Dr. Nicholas Caro Explains St George's Laser - (video)
Although there are different lasers available to perform corrective eye surgery, Dr. Caro only uses the Nidek EC 5000 scanning laser. After thoroughly researching the options, he selected the Nidek because it provides the best results. It is the most widely used laser.

What is custom Lasik?
Custom Lasik is an individualized Lasik procedure. We use the iTrace system, a precise and objective method for measuring refraction, to create a map of the eye. When iTrace is used with the Nidek laser, the result is clearer crisper vision.

Dr. Caro, why did you decide become an ophthalmologist?
While I was an intern at Cook County Hospital in Chicago, I observed an eye operation that successfully restored sight to the patient. I decided right then that I wanted to help people see better.
