Blended Vision is an advanced laser treatment for treating patients with symptoms related to presbyopia.
What is Laser Blended Vision?
Using a sophisticated ablation profile, Laser Blended Vision (LBV) can be used to treat patients who are experiencing progressive loss of ability to focus on nearby objects,- a condition known as presbyopia.
The technique is an advancement of monovision in which one eye is set for distance vision and the other is set for near vision. The laser creates a profile within the cornea to allow for an increased depth of focus resulting in a more continuous range of focus.
It offers the opportunity to achieve freedom from glasses by combining the simplicity and accuracy of corneal refractive surgery with the benefits of increased depth of field in retaining visual quality.
How does Laser Blended Vision work?
Blended Vision is a LASIK procedure where the excimer laser makes one eye (non-dominant eye) a little nearsighted. Your dominant eye then sees clearly in the distance and the non-dominant eye sees near.
Laser Blended Vision is not just making the non-dominant eye near sighted as monovision. The laser also creates a positive spherical aberration in the center of the eye. This correction makes the image disparity from the two eyes smaller and the brain blends the images together even better that you will not notice which eye you are looking through for distance or near.
Both eyes are usually treated to ensure the best possible balance of vision. The laser reshapes the surface of the cornea just as it is done in conventional laser eye surgery. During conventional laser eye surgery the laser reshapes the cornea so that the power is the same throughout the whole cornea. This is not the case for blended vision as the laser creates different power zones so that parts of the cornea are corrected for distance vision and the other parts for reading vision.

Blended Vision is an advanced method for treating patients with presbyopia. It offers the opportunity to achieve freedom from glasses by combining the simplicity and accuracy of corneal refractive surgery with the benefits of increased depth of field in retaining visual quality. As a surgical solution based on the naturally occurring spherical aberrations of the eye, blended vision extends the scope of customised ablation beyond the limits of conventional monovision laser methods in several ways.
Similar to conventional monovision, the dominant eye is corrected for distance vision, whereas the non-dominant eye is corrected to be slightly myopic for near vision. This micro-monovision strategy is further enhanced by a decisive difference: an increase in the depth of field of each eye using a wavefront-optimized ablation profile to create a continuous refractive power gradient for the whole optical zone of the cornea. Blended vision is an individualized treatment plan based on preoperative spherical aberrations and the functional age of the eye. As a result, a customized fusion of the two images for near and distance vision is created for each patient – the so-called “Blend Zone”.
LaserVision was initially founded in Guildford, Surrey. Now with clinics in over 6 locations, we are able to treat the eye conditions of patients nationwide. This treatment is available at:
