Generally this treatment is for the over 40 age group. This is the first technique that avoids laser altogether in treating lower levels of long sight. It uses RF (radiofrequency) technology to reshape the cornea. No tissue is removed and there are no cuts invlved. It avoids the line of sight, helping to preserve night vision. Because it supplies most of its energy to the deeper layers of the cornea, it is more likely to last than other systems, such as Holmium LTK, which mainly treat the superficial part of the cornea.

This procedure may also be used to correct Presbyopia (the need for reading glasses), through creating “blended vision”. Unlike “monovision” where one eye is treated for near vision and the other for distance vision—the aim of blended vision is to improve near vision without compromising binocular distance vision. Because the eyes continue to change with age, it is likely that patients will need additional vision correction either enhancements or refractive multifocal lens exchange, which is permanent. That makes this a more temporary option rather like plastic surgery . People often prefer the simpler CK for now and plan for multifocal refractive lens exchange (RLE) several years later.
