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.

Who qualifies for laser eye surgery?

Who qualifies for laser eye surgery?

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.

Surgery FAQ's

Surgery FAQ's

Do I need to do any tests before my surgery?

If it is required by the surgeon or the policy of the Outpatient Surgery Center (OSC), you may be required to have PREOPERATIVE CLEARANCE at the Outpatient Assessment Center (OPAC) at 2050 Kenny Road, 2nd floor (this appointment will be made by the surgery coordinator). This may be done by your primary care physician, but the OSC prefers an OPAC assessment. It is your responsibility to schedule the appointment with your primary care physician within 30 days of the date of surgery. The surgery coordinator will fax orders to your primary care physician once a fax number is provided.

Preoperative testing varies by the type of surgery, but may include History & Physical, Labwork, EKG, etc.

In addition, you will receive a phone call from a nurse with the OSC 1 week to 1 day prior to your surgery to do an over the phone health assessment.

Do I need to take any additional medication?

Please take any eye drops prescribed as directed by your physician. Prescriptions may have been electronically sent, so please check with your pharmacy. These drops will also be used after the surgery as well. If you should run out of your drops, please check with your pharmacy for a refill. Any questions about your drops should be directed to the main number 
614-293-8116 option 2 and leave a message for your surgeon's technician.

Will I need a driver?

You MUST have a responsible adult that you know bring you to the surgery, preferably stay in the facility or at least check in with you and provide a contact number, drive you home and drive you back
for your 1 day postoperative appointment.

How should I prepare for surgery?

It is important to follow these simple precautions before arriving:

• Do not eat or drink anything (including water, coffee, candy, gum or mints after midnight before your surgery. This includes medicines taken by mouth, unless you are instructed to do so by your           surgeon or anesthesiologist. You may brush your teeth, but do not swallow the water. It is important to have an empty stomach before your surgery.
• Do not smoke after 6 p.m. the night before your surgery.
• You may take a bath or shower the morning of your surgery.
• Wear casual, loose-fitting clothing.
• Do not wear makeup, nail polish or hair pins.
• Please leave jewelry and other valuables at home.
• Bring a storage case for contact lenses or glasses, as they cannot be worn during surgery.
• Limit the number of people bringing you to your appointment. Adult patients should be escorted by one adult.
• If you have a living will or durable power of attorney, please bring a copy of this document with you.
• Per hospital policy, please bring a photo ID, insurance card, and copay.

What can I expect the day of surgery?

What you can expect before, during, after surgery and at home.

Before Surgery

You should arrive at least one and a half hours prior to your surgery, or as directed by your surgeon's office or that surgery center. The OSU Surgery Center (OSC) opens at 6:15 a.m.  Check in at the reception desk. The OSC staff will complete your paperwork and ensure you are identified correctly for your procedure.

You will be taken to a private area where you will change into a hospital gown, your medical information will be reviewed for accuracy and an IV will be started.

There will be several care team members who will want to speak to you in preparation for surgery, including:

• Nurse
• Surgeon
• Anesthesia provider

Your vital signs, such as your blood pressure, pulse and oxygen level, will be monitored. 

Your family member or support person will have access to TV monitors located in the surgery center waiting area to track your progress in surgery and recovery.  It is important that your family member or support person stay in the facility during your surgical visit so we can find them if we need information or if a care team member needs to speak to him or her.

During Surgery

You will be taken back to the operating room from your private preparation area. The operating room staff will greet you and prepare you for surgery. We will ask you to confirm your identity and the procedure you are about to have. This is part of our patient safety practice to ensure you receive the appropriate treatment.

After Surgery

Once your surgery is complete, your surgeon will update your family member or support person. You will awaken in the recovery room. Managing your pain level is extremely important to us. We want to make sure you are comfortable. We will be asking you to rate your pain often, and we will closely monitor your pain levels while you are coming out of anesthesia.

You may be provided light nourishment when you awaken if permitted by your surgeon. We welcome your family member or support person to be with you as we review your discharge instructions, provide you with prescriptions and answer any of your questions before you go home. It is very important that your family member or support person be there for this step to help you with details since you may still be drowsy from the anesthesia.

After anesthesia, you should rest for 24 hours and clear your day. Do not drive, drink alcoholic beverages or make important decisions/ sign legal documents during this time.

At Home

If you have any concerns during the evening, please contact your surgeon. If you have any emergency needs, please go to the closest emergency department. A nurse from the Outpatient Surgery Center will call you the next business day to check on how you are feeling.

Our first concern is your recovery and any medical issues you may have. It is important to us that we provided you exceptional care. We encourage you to ask questions or share concerns when we call you.

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 eye surgery 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 Columbus, 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 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.
