How is CK performed?
Conductive Keratoplasty (CK) uses radio waves instead of a laser to reshape the
cornea and bring your near vision back into focus. It is performed using a small probe
thinner than a human hair that is applied in a circular pattern on the outer cornea to
shrink small areas of collagen. This shrinkage pattern creates a constrictive band, like
the tightening of a belt, which increases the overall curvature of the cornea. The
procedure takes less than three minutes and is done in our office with topical
anesthesia (eye drops).

Does CK require a laser?
Rather than removing tissue with a laser, CK reshapes the cornea using an entirely
different method—the application of radiofrequency energy—to increase the overall
curvature of the cornea and improve your near vision.

Will you be cutting the cornea?
CK is performed without the cutting or removal of tissue. Using a probe as thin as a strand of human hair,
radiofrequency energy is applied to the cornea in a circular pattern to steepen the overall curvature of the cornea,
resulting in improved near vision.

What is Blended Vision?
Your doctor may recommend Blended Vision to treat your presbyopia (loss of near vision). Unlike monovision,
Blended Vision improves your ability to focus on near objects without sacrificing distance vision in the treated eye,
making it easier for you to adjust to the two separate images. If you have not tolerated monovision treatments in
the past, Blended Vision may be a better choice for you.

Can CK correct nearsightedness?
CK was designed for baby boomers who struggle to read menus, price tags, or to see their computer – symptoms
of fading near vision which require a steepening of the cornea. CK is not designed to flatten the cornea, the effect
required for the treatment of myopia (nearsightedness).

Will I ever need glasses or contacts again?
Depending on your age and your type of refractive disorder, you may need additional vision correction at some
point. This is because your eyes will continue to change as you age.

                            Will my vision improve immediately after the procedure?
                            Patients usually notice an immediate improvement in their vision after CK. However,
                            it usually takes several weeks for the eyes to reach the final level of correction.

Will my vision fluctuate after the procedure?
Most patients will experience mild fluctuation in their vision after the procedure, which will usually subside
within a few weeks. Patients who undergo vision procedures for farsightedness usually require a longer
stabilization period than those treated for nearsightedness.

What results can I expect?
Near Vision Improvement:
Two-thirds of our patients have good distance vision and want to improve their near vision, thus they require CK
in only one eye. It is a technique used widely in contact lenses and LASIK for patients over 40. It is similar to the
sound you hear from stereo speakers: a different sound comes from each one, but they work together to provide
the entire range of sound. With CK, you can see a more complete range of distance and near again.
Distance Vision Improvement:
One-third of our patients require CK in both eyes because they have become more farsighted with age. They
benefit from having treatment in one eye to sharpen their distance vision, and treatment in the other eye to sharpen
their near vision. These patients experience improvement in near vision and improve on average from 20/40 to
20/20 at distance .

Are both eyes treated on the same day?
CK is typically performed on just one eye. However, for patients who require treatment in
both eyes, CK is typically performed on both eyes on the same day because the procedure is
minimally invasive and requires only a few minutes to perform.

How soon will I be able to return to work?
The majority of patients are able to return to work and other normal activities one to three
days after CK. Although recovery is fairly quick, it is advisable to be careful with your eyes and
avoid any strain. Those whose jobs demand intense clarity of vision (such as dentistry,
surgery, or computer work) may find their work more difficult to perform for several days after
the procedure.

What will I feel during the procedure?
CK is virtually painless. You will be aware of a lid support used to help hold your eyes open. The most common
sensation that patients experience is a feeling of pressure on the eye. After the procedure, there may be some mild
discomfort, and many patients experience a foreign-object sensation or “scratchiness” in the eye, which usually
subsides within 24 hours of the procedure.

Will I have to wear eye patches following CK?
You will not have to wear patches or bandages. However, your eyes may feel scratchy and light sensitive for the
first 24 to 36 hours. Wearing sunglasses and keeping your eyes closed as much as possible will help ease these

                                      Frequently Asked Questions (continued)

What are the restrictions after having CK?
As with any other type of vision procedure, certain precautions should be taken after CK. Avoid getting
contaminated water in your eyes for at least one week, including water from swimming pools, spas, lakes, and the
ocean. When bathing, keep your eyes closed to avoid getting soap or water in them. When exercising, sweat
should be kept away from the eyes for at least one week after surgery. Eye makeup should not be worn for one
week. You should also avoid rubbing your eyes for two weeks following the procedure.

Is CK permanent? Is it reversible?
With CK, we are able to turn back the hands of time, but we cannot stop the clock from ticking. We can return
you to the time when you just started relying on glasses for close work. As you age, so do your eyes. Although the
effect of CK is permanent, your vision will continue to naturally weaken with time. As with most vision
correction procedures, CK is not reversible. Once the procedure has been performed, it is not possible to remove
its effects. Make sure to discuss your vision needs with your optometrist to make sure CK is right for you.

What are the risks and side effects?
Because CK is minimally invasive and very controlled, the procedure has very few surgical complications. During
the first 24 to 48 hours after surgery, you may experience tearing and some discomfort, including the sensation of
a foreign object in the eye. You may also experience a slight overcorrection of your vision, allowing you to see
better at near, although your distance vision may be blurry. Your vision will stabilize during the following weeks.
