Presbyopia Treatment (Advanced PRESBYOND 500Hz Laser Blended Vision)

The Laser Blended Vision treatment is customized for individuals with presbyopia. It creates a unique overlapping zone (Blend Zone) in the intermediate range. This makes it easy for the two eyes to merge the images for normal binocular vision and enables clear focus at all distances.

Binocular Vision

The unique Blend Zone maintains contrast sensitivity and preserves stereo-acuity very well. This makes it easier for the brain to maintain its binocular vision by merging the images of both eyes for your normal 3D vision. Most patients experience an immediate Laser Blended Vision improvement. They are able to adapt faster to their new eyesight. In addition, the procedure is tolerated by the vast majority of patients – up to 97 %2.

The Advanced PRESBYOND 500Hz, in conjunction with the ZEISS MEL90 laser vision correction platform, features a significant enhancement with a laser reshaping speed of 500Hz. This represents a twofold increase compared to the previous generation's 250Hz, greatly reducing the time required for laser reshaping.
