What is presbyopia?
Our ability to see nearby objects deteriorates with age. This condition is common and known as presbyopia. Although it can not be reversed, it is easy to correct. The simplest way is to wear reading glasses. Laser treatment and other kinds of eye surgery have few advantages, but are associated with many risks.
Presbyopia usually becomes noticeable in your mid-forties, and usually begins as only a problem when reading. Wearing reading glasses is a simple and effective solution for people who don’t already have other problems with their eyesight. Those who already had to wear glasses or contact lenses beforehand can use varifocal or multifocal glasses to avoid having to switch between different pairs. Multifocal contact lenses are an alternative to multifocal glasses. They also allow you to see both nearby and distant objects clearly.
Laser treatment and other kinds of eye surgery are called refractive surgery. The aim of these procedures is to change the refractive power (focusing power) of the eye in order to correct your vision. They can’t yet effectively reverse presbyopia. What’s more, most of the procedures are still being tested. The advantages of not having to wear glasses or contact lenses have to be weighed against the possible risks associated with the procedure. For instance, your spatial vision may be worse afterwards, or you may struggle to seeing things that are further away.
So if you wear reading glasses, varifocals, or bifocals (or are trying to put them off), we can almost certainly help.

Laser Blended Vision (LBV)
Laser Blended Vision (LBV) is an advanced form of LASIK surgery designed to address presbyopia, the age-related loss of near focusing ability. In traditional monovision, one eye is corrected for distance and the other eye is corrected for near vision. However, many patients report that intermediate ranges are unclear, especially if the difference between both eyes is significant. :BV enhances both eyes’ depth of focus through precise corneal reshaping and creating a gradient of power across the cornea. This approach creates a “blend zone,” allowing the brain to seamlessly integrate images from both eyes for clear vision at all distances.

Zeiss (Germany) MEL90
PRESBYOND is a form of LBV powered by the MEL90 that creates a “blend zone” in the intermediate range between both eyes, providing a clear range of vision across all ranges. MEL90 uses a non-linear aspheric ablation profile that creates a refractive power gradient across the cornea.
