If you’re doing research about LASIK, you’ll read a lot about the benefits of the surgery itself: little to no pain, immediate vision correction, and quick recovery times.

The true benefits of LASIK are the changes it makes in your life. No more reaching for glasses in the morning to read the clock, or buying bottles of contact lens solution. No more frames sliding off your nose on a hot day, or losing a contact in the middle of your workout. No more choosing between glasses or contacts on your vision benefits when you really need both. LASIK means hassle-free vision, all the time. It’s just you and your own eyes.

Here, we’ll share some information about our experts and the tools they use, how to make LASIK an affordable option for your vision correction, and answer some of the most common questions people have about LASIK. When you’re ready do take the next step, so are we.

Faster. Safer. More precise. 

Ohio State has the most advanced LASIK technology available in central Ohio.

When it comes to your vision, there is no room for compromise – you want the confidence that your surgeon is using equipment and procedures that are state-of the-art. That’s why people trust their vision to Ohio State.

During your evaluation, our doctors will familiarize you with all the benefits of our LASIK process, but the most exciting feature of Ohio State LASIK is called topography-guided laser vision correction. Just like a topographic map captures changes in land elevation, Ohio State’s LASIK system maps the surface of your eye, giving our doctors the ability to develop a unique vision correction plan for you. Rather than simply treating your vision based on your eyeglass prescription, we can pinpoint and correct the smallest imperfections of your cornea and its curvature. The result is a personalized focusing surface for each patient, and each eye. Many patients experience better quality vision following a LASIK procedure than they ever had with contacts and glasses.

There’s also no moving around from laser to laser for patients once the procedure begins. Our patient table shifts from the laser that prepares your eye for correction to the one that corrects your vision. This connectivity makes the entire procedure faster and more precise, making you more comfortable.

Our new LASIK system represents a significant advancement in laser vision correction. LASIK has never been faster, safer or more accurate. If you’ve been waiting for the right time to have LASIK, now is the time.

The laser is the tool. The doctor is the difference. The place is Ohio State. 

LASIK laser technology continues to make important advancements, but there’s no substitute for experience. Ohio State’s David Castellano, MD, has been performing LASIK surgeries for 20 years. Together with colleagues Amit Tandon, MD, and Rebecca Kuennen, MD, Ohio State brings nearly 40 years of combined LASIK experience to each procedure.

“We provide very personalized care," Dr. Castellano says. "You’ll always see me directly when you make an appointment at my office. Most of my patients have my cell phone number and can reach me any time. If a patient has a problem, I’ll always make time to see them. Working at Ohio State offers many opportunities to stay on the leading edge of eye care. I just keep learning.”

At Ohio State’s Havener Eye Institute, our doctors are here to help you make a well-informed decision about your vision, to answer your questions and address your concerns. No gimmicks, no high-pressure sales. Just the information you need to do what’s best for you.

Why Choose Ohio State?

Why Choose Ohio State?

We use advanced, all-laser technologies, which offer considerable advantages over traditional procedures. Ohio State’s surgeons use the most advanced technologies to diagnose corneal issues and perform surgical procedures. Our surgeons measure the optical distortions of the cornea and produce a map showing how light is distorted in your eye. This highlights individual imperfections and tailors laser settings for the best results, including improved nighttime vision.

In addition, our experts are backed by the resources, research, education, technology, teamwork and reputation of The Ohio State University Wexner Medical Center. We have a tireless dedication to patient safety, and our surgeons strive to give every patient first-class service and the highest-quality result.

Ohio State eye care specialists provide thorough consultation and support every step of the way. We are happy to answer any questions and look forward to meeting with you soon.

Advantages of Bladeless LASIK

Advantages of Bladeless LASIK

At Ohio State’s Havener Eye Institute, we perform state-of-the-art, blade-free, all-laser LASIK for the best vision outcomes. We currently use the latest technologies, such as the Wavelight Refractive Suite, which includes the FS200 Femtosecond laser for flap creation and the Excimer 500 laser for personalized vision correction. This allows our surgeons to serve a wide variety of patient needs.

The FS200 Femtosecond laser creates a much thinner corneal flap as compared to a flap created with a microkeratome (hand-held blade). Patients who were previously told their corneas were too thin for LASIK may now be eligible for the treatment.

The WaveLight laser customizes every treatment to the patient’s individual prescription and cornea. This personalized treatment enhances the quality of vision and also addresses any distortions that may affect night vision. Recent studies indicate that with wavefront-optimized technology, patients are more likely to achieve 20/20 vision.

What can LASIK correct?

What can LASIK correct?

Vision can become blurry when the cornea, the clear front part of the eye, is shaped abnormally and light doesn't bend, or refract, properly as it reaches the retina in back of the eye. Such problems are called refractive errors. They can include:

  • Nearsightedness (myopia) where distant images seem blurry
  • Farsightedness (hyperopia) where near and distance images seem blurry
  • Astigmatism (also close-up or distant images seem blurry)

LASIK can correct these vision problems. In some cases, laser surgery for refractive errors may reduce or eliminate the need for eyeglasses or contact lenses.

As the natural lens inside the eye ages, it can lead to decreased near vision (presbyopia). This results in the need for reading glasses. LASIK does not correct presbyopia, however, monovision is a possible treatment option. Discuss monovision with your physician.



With nearsightedness, distant images appear blurred, because the shape of the eye causes the focal point to be in front of the retina. 



With farsightedness, nearby images appear blurred, because the shape of the eye causes the focal point to be behind the retina.



Astigmatism is caused by abnormal curving of the surface of the eye, which leads to out-of-focus, blurred vision.
