How does Near Vision CK or Near Vision LASIK work for presbyopic patient?

CK (Conductive Keratoplasty) uses radio waves to help reshaping the cornea but LASIK uses laser and need to cut then remove some tissue to changes the curvature of the cornea. 
These heralded new procedures, Near Vision LASIK or CK, are treatment, which, unlike the typical surgery, treats only one eye. 
You will notice that there is a little difference between your two eyes for the first couple of weeks after surgery. 
The brain theoretically adapts to one eye seeing near and the other (dominant) seeing far. 
Your brain will learn how to work with your new vision, which will be functional, but may be a little frustrated at times. 
You will experience some halos, or glare at night and there exists a question regarding depth perception. 
So they are not a perfect solution for the athlete or night driver.
They are not designed for very fine print, like stock pages, box scores, and the instructions on medicine bottles or reading for a long time, consequently extensive reading requires glasses.
It is your eyes that continue to change with each and every birthday.  Most people have increased the power of their reading glasses a couple of times since they first started needing them, because the eyes are getting older and weaker. 
Some patients understand it is because of the stiffening of the lens and weakening of the focusing muscle inside the eye. 
The lens no longer bends and flexes like it used to.  So, it is not that these procedures do not work; it that your eyes are continuing, on their own, to get weaker. 
The procedure showed good stability from the clinical trials but re-treatment would be required.

We truly believe that the risk/benefit ratio favors SuperSight Surgery in many presbyopic ametropes. 
As we continue to see improvements in technology and we believe SuperSight Surgery to be the wave of the future.
