The Benefits of Laser Blended Vision (LBV)


No more glasses or contact lenses.

Improvement of the acceptance rate to 97% compared to standard monovision (50-60%), the standard technique used to correct presbyopia.

If you are amongst the 3% that does not adapt to the procedure, it is reversible.


Laser Blended Vision (LBV)

The standard technique used to correct presbyopia with laser is called monovision. It consists of correcting the dominant eye for distance vision and the non-dominant eye for near vision.

Previously, this correction has been used by means of contact lenses and for several years now by using LASIK. The acceptance rate of monovision goes from 50% to 60%.

Normally, when one looks at something, the image from the right eye is superposed over that of the left in order to create a clear image in the brain. In the case of monovision, since one image is clear and the other is blurry, the brain must eliminate the blurry one in order to keep only the clear one. For some, this practice is easy, but for others, it is impossible, which is why the acceptance rate of monovision is quite low.

Laser Blended Vision uses the principle of monovision with the addition of a depth of field correction, which improves intermediate vision. Therefore:


Distance vision with the dominant eye: good distance vision and better intermediate vision.
Near vision with the non-dominant eye: good near vision and better intermediate vision.
Improving the depth of field of both eyes allows for the images from both the near eye and the far eye to align with each other. The greater their resemblance, the easier it is to fuse them into one image. In this way, distance, intermediate, and near vision all become clearer. Furthermore, unlike monovision, there is no loss of stereoscopy (relief) with LBV.
