At Columbus Ophthalmology Associates, our fellowship-trained refractive surgeons can review your unique ocular condition and provide you with the most specialized surgical option.

Are you a candidate?

Learn how LASIK may improve your vision.

If you suffer from nearsightedness, farsightedness or astigmatism and want the freedom to live your life without glasses or contacts, you may be a good candidate for refractive surgery. The first step is to schedule an appointment with Dr. Thomas Litzinger, a fellowship-trained cornea and refractive surgeon. During your consultation, he will discuss your current lifestyle, health history, medications, and post-surgery expectations. After a thorough eye exam and testing, Dr. Litzinger will confirm whether you are a candidate for refractive surgery and explain the procedure that best fits your needs. He will answer any questions you may have to ensure you are able to make an informed decision.


A patient’s satisfaction following refractive treatment is greatly dependent on their expectations. Most patients’ results make everyday tasks possible without the need for eyeglasses or contacts. However, eyeglasses may still be needed for reading fine print or distance activities, such as night driving. It is best to consider refractive surgery as a means to reduce dependency on eyeglasses and contact lenses.

While refractive surgery is completed with very precise lasers, visual outcomes will vary from patient to patient. This occurs for many reasons, such as the degree of refractive error corrected and individual healing tendencies.

Custom LASIK

At Columbus Ophthalmology Associates, we utilize advanced technology to perform custom LASIK for patients.

With Custom (or wavefront optimized) LASIK surgery, it is now possible to create a 3-D map of the patient’s eye to display even the slightest imperfection, similar to a person’s fingerprint. The map is transferred directly to the laser resulting in higher levels of precision and treatment accuracy. Due to the precision and accuracy of the procedure, patients have a greater chance of having 20/20 vision. There are fewer incidences of glare and halos, with the potential of better overall vision, even at night. In addition, the potential exists for patients to have better vision than is possible with glasses or contacts.


During Custom LASIK, a laser is used for a bladeless procedure. First, instead of the microkeratome blade that was used in traditional LASIK, the FDA-approved femtosecond laser is used to create a flap with laser energy, allowing customization of the flap. The femtosecond laser is capable of creating extremely precise flaps of uniform thickness by producing tiny bubbles inside the cornea that are 1/10,000 of an inch in diameter. The laser beam cannot penetrate into the eye beyond the cornea, and therefore is extremely safe. After the flap is created, an excimer laser is used to reshape the cornea in order to reduce farsightedness, nearsightedness, or astigmatism. The flap is returned to its original position, and seals itself without sutures.

Custom LASIK is performed as an outpatient procedure that takes approximately 10-15 minutes. With the precision that the femtosecond laser provides, some patients who were once considered unsuitable for LASIK due to thin corneas may now be suitable candidates. Furthermore, research has shown that more patients achieve vision that is 20/20 or better with femtosecond custom LASIK as compared to other methods. Therefore, Columbus Ophthalmology only offers their patients the best: bladeless, custom/optimized LASIK with a femtosecond and excimer laser.


Learn how Photorefractive Keratectomy surgery is performed.

PRK (Photorefractive Keratectomy) is a laser correction surgery very similar to LASIK that is commonly used for patients with a thin cornea. While LASIK procedures cut a flap in the cornea, PRK removes the outer layer of the cornea (epithelium), and then the same excimer laser used in LASIK sculpts the cornea to correct refractive error. PRK is considered a safer procedure for patients with thin corneas since more of the cornea is left untouched during the procedure. In addition, patients experience less dryness following PRK. However, the patient is left with a corneal abrasion that will take 3-5 days to heal. During that time the patient will wear a soft contact lens that acts as a bandage to minimize pain, promote healing, and protect the cornea. PRK patients usually experience mild to moderate discomfort during the healing process. Blurry vision is common and it may be several weeks before vision is clear and stable.


Learn about treating presbyopia and whether monovision is right for you.

Monovision is a refractive surgery technique used for patients with presbyopia. Presbyopia is the loss of ability to focus on objects close up due to the normal aging process. It will affect everyone as they enter their 40s. The technique uses refractive surgery to enable one eye to focus for close vision, and the other eye is left untreated, or, if needed, treated to focus for distance vision. While monovision will reduce a patient’s need for glasses or contacts, glasses may still be necessary for fine print.

It is important to discuss your lifestyle with your surgeon prior to making a decision. It can be difficult for some patients to adjust to monovision. The brain will eventually adjust after six to eight weeks, but that may not be acceptable for some patients. In addition, active individuals who play golf or tennis or drive a great deal at night may not be good candidates for monovision.

Visian ICL

Learn how Implantable Collamer Lenses can improve your vision.

Visian ICL (Implantable Collamer Lens) is a procedure very similar to cataract surgery. However, unlike cataract surgery, the patient’s crystalline lens is not removed. While it is a type of refractive surgery, no corneal tissue is reshaped or permanently removed. The lens is constructed of collagen-based Collamer and compatible with your body’s natural chemistry. Visual improvement is immediate and permanent as long as the lens remains in the eye. However, if in the unlikely event a patient experiences issues with the lens, it can be removed or replaced. Additional benefits of the Collamer include UV protection and anti-reflectivity.

The procedure is performed as an outpatient surgery and is completed in 15-20 minutes. One to two weeks before the procedure, the patient will have a YAG laser iridotomy performed to make one or two small openings near the edge of the iris (the colored portion of the eye). The openings are important to allow fluid in the eye to circulate around the new lens when it is inserted.

To insert the ICL, a very small opening is created in the cornea. The lens is folded into a special cartridge that allows the lens to be injected through the opening. The lens will then open and settle into place. During both the YAG laser and ICL implantation, patients are given topical anesthetic eye drops and medicine to relax so they do not experience any discomfort.

Kamra Inlay

Learn how this procedure may benefit your vision long-term.

Kamra Inlay is an innovative procedure that provides patients with restored near vision, and reduces the need for reading glasses, which those with presbyopia and blurry near vision rely on. Even with age and as presbyopia progresses, Kamra Inlay allows patients the ability to enjoy clear vision over time. This procedure is ideal for patients that are looking to reduce their dependency on reading glasses and contacts for near vision.


The Kamra Inlay procedure places an inlay in the first few layers of the eye known as the cornea. This inlay is smaller and thinner than a contact lens and is a mini-ring with an opening – or pinhole – in the center. The pinhole allows only focused light to enter your eye. Because the inlay is placed in only one of your eyes, it allows you to see up close but also maintain your distance vision in both eyes. Your non-Kamra eye is left untouched, and working together, the eyes allow you to see both near and far. Watch the video to the right to help further explain how Kamra Inlay works.


COA’s Dr. Litzinger has performed Kamra Inlay on many patients and their results have changed their dependency on reading glasses. Patients like David Kirkbride, who was one of the first to have Kamra Inlay in Ohio, are thrilled with the results: “I used to go to restaurants and have a hard time reading the menu. Now I have crystal clear focus…I had lost my near vision but now I’m happy to have it back. I appreciate my sight all over again.”
