NearVision Conductive Keratoplasty

Approved by the United States Food and Drug Administration (FDA) in 2002, NearVision ℠ conductive keratoplasty (CK) can help reduce your dependence on reading glasses. This non-laser treatment for farsightedness and presbyopia uses radiofrequency energy to correct the shape of the cornea. Unlike laser-assisted techniques, NearVision CK does not require the removal of corneal tissue. Instead, the radiofrequency energy causes the tissue of the cornea to contract, creating a steeper shape. NearVision CK is intended for appropriate candidates over the age of 40 with good distance vision. 

As the first ophthalmologist in the Washington, D.C. area to perform the CK procedure, Dr. Andrew Holzman has been at the forefront of this vision correction technology. He served as a regional training instructor for the CK procedure and is the go-to surgeon for this type of correction. He has performed thousands of vision correction procedures, and he provides the highest levels of care to each of his patients. 

Treating Presbyopia with CK

The crystalline lens lies behind the cornea and plays a vital role in focusing incoming light onto the retina. The lens loses flexibility as we age. By our mid-40s, this can result in difficulty focusing on close objects. This age-related form of farsightedness is known as presbyopia and differs from hyperopia (farsightedness). If you have been diagnosed with presbyopia and wish to reduce or eliminate your need for corrective eyewear, CK may be a suitable option for restoring your near vision.

CK can change the shape of the cornea to accommodate for a lens with compromised flexibility.

Why Choose CK over Other Treatment Options?

The most common treatment for hyperopia or presbyopia is reading glasses. If you already wear glasses or contacts, bifocal lenses are also an option. These lenses are divided in two, usually with the top half of the lens adjusted for distance vision and the bottom half of the lens adjusted for close vision.

Traditional bifocals have a visible line across the lens. Progressive addition lenses (PALs) are unlined, which can eliminate the self-consciousness many patients feel about wearing bifocals.

Multifocal and bifocal contact lenses are another option. There are both traditional and implantable contact lenses available in both varieties. Implantable contact lenses require a much more invasive surgical procedure than CK. The other options are all temporary treatments. Glasses, especially bifocals, can make patients feel self-conscious about their appearance. Glasses are also easy to lose and break.

Unlike laser-assisted techniques, NearVision CK does not require the removal of corneal tissue. Instead, the radiofrequency energy causes the tissue of the cornea to contract, creating a steeper shape.

For some, contacts can be a viable alternative, but if you prefer to avoid touching your eye, contacts may not be a good solution. For the right candidates, CK provides many benefits. It offers a permanent solution without the need for invasive surgical procedures or the implantation of a foreign object.

With CK, you can see closely without reading glasses (or worse, having to hold the object at an arm’s length to see), and you can feel confident about your appearance. Avoiding the need for bifocals or reading glasses can also help you maintain a youthful appearance.


Dr. Holzman conducts stringent testing to ensure that patients can safely undergo the treatments he recommends. While there are many candidacy requirements for undergoing CK, the best candidates are:

  • Over 18 years of age
  • Not pregnant or breastfeeding
  • Free of autoimmune disorders
  • Willing to experience a slight decline in distance focus

During your consultation, your ophthalmologist will conduct a detailed review of your health history, your ocular health, and your goals to determine if CK or another procedure is the best way to address your farsightedness or presbyopia. 

Risks and Benefits of CK

corneal curvatureNearVision CK is a safe and minimally invasive procedure. As such, patients typically experience few side effects and enjoy a short recovery time. Some patients can return to work and most normal activities as early as the day following the procedure. Their vision continues to improve over the following weeks. Ninety-eight percent of NearVision CK patients achieve a level of visual acuity that allows them to read newspaper-size print without reading glasses.

Conductive Keratoplasty stepsThere are a few risks associated with NearVision CK. Less than one percent of patients who undergo the procedure experience complications such as corneal scratches or eye infections. Other side effects such as glare, blurred vision, and watery eyes are considered temporary and usually subside within a few months.

The Day of the CK Procedure

We will cleanse the area around your eyes and then apply anesthetic eye drops to numb one or both eyes. Once the numbing drops have taken effect, Dr. Holzman will use a pen-shaped instrument with a cool, thin tip to apply radiofrequency energy in a circular pattern. 

After the Procedure

Dr. Holzman will provide you with some medications to minimize these side effects. You will need to avoid using eye makeup and getting water in your eyes for at least four days after surgery. For up to two weeks, try to avoid rubbing your eyes. Dr. Holzman will provide you with explicit aftercare instructions and schedule follow-up appointments to ensure that you are healing properly.

Find out if CK is Right for You

If you are farsighted or presbyopic and want to reduce or eliminate your need for reading glasses, contact our office to schedule a consultation with Dr. Holzman at one of our five convenient locations in the Washington D.C. area. After a thorough eye examination to test your vision and ocular health, he can determine whether you would benefit from NearVision CK. There are very few restrictions on candidacy for the procedure, and many patients in their 40s and 50s qualify. We look forward to helping you find a vision solution that fits your lifestyle.
