Conductive keratoplasty is a type of refractive surgery that uses radio waves to adjust the contour of the cornea by shrinking the corneal collagen around it.
Overview of Conductive Keratoplasty
If the patient has a clear distance vision, and the only problem is unfortunate near vision due to presbyopia, conductive keratoplasty is performed on only one eye. This creates a mild form of monovision, meaning that one eye is corrected for near vision while the other eye is stronger for distance vision. While CK can improve near vision, the procedure doesn’t cause as much blurring of distance vision as monovision with contact lenses or laser vision correction procedures such as LASIK.
Conductive Keratoplasty Recommended For:
- Patients who are over 40 years old
- patients who have had reasonable distance vision the entire life but now need reading glasses
Before Conductive Keratoplasty
Patient will meet with an eye doctor to go through medical history taking and eyes will be fully examined. During the consultation, an instrument called a corneal topographer will be used to create a detailed map of the curvature of cornea. The topographer doesn’t touch the eye, and the measurement is similar to having a close-up photograph taken of eye’s surface.
During Conductive Keratoplasty
The surgery will be 10 minutes for each eye. Numbing drops are applied to eyes prior to surgery to make the procedure comfortable and decrease natural urge to blink. Also, a small device will hold the eyelids open during the procedure so that patients can’t accidentally blink.
After Conductive Keratoplasty
There may be pain or a foreign body sensation, particularly during the first 24 hours after surgery, which is normal. Patients should be careful and not rub their eye. The surgeon may place a transparent protective shield over eye to help protect the cornea as it heals. Patients may be slightly nearsighted for a few weeks or even months, which is normal. for at least one week after surgery, patients should avoid swimming, using a hot tub or participating in any other activities where water may splash into eyes. When showering during this period, eyes should be closed as much as possible.
