Your brain figures out how to use your monovision to provide correct focus at whatever distance you are looking at. By fitting one eye with a contact lens for close up vision and one for distance vision, people with presbyopia may be able to function without the need for additional reading glasses.

Lindstrom, MD, managing partner at Minnesota Eye Consultants and an attending surgeon at the Phillips Eye Institute and Minnesota Eye Laser and Surgery Center in Minneapolis, reports that he recently conducted a pilot study with Marlane Brown OD, involving 10 patients who were disappointed with their near vision after Crystalens and ReZoom multifocal IOL implantation. The brain adjusts and they feel they see clearly for both distance and near, without the help of glasses. This technique allows individuals to use a combination of their two eyes to see far away objects and close up objects. We have modules designed to facilitate different goals, such as enhanced contrast sensitivity or enhanced near visual acuity. While Monovision is not a perfect solution to presbyopia, for carefully selected patients, it is well tolerated and very satisfactory over 85% of the time.

No. Monovision counters the deterioration of the ability to see up close but also causes dramatic visual distortions. One would face major discomfort while driving, especially at night, and the glare from headlights would only add to the problem. In multifocal IOL pseudophakes, neural plasticity probably explains several things: the commonly observed improvement in contrast sensitivity at six months postop; better contrast sensitivity in bilateral multifocal IOL pseudophakes compared to unilateral multifocal pseudophakes; and perceptual learning after surgery, when experience produces reasonably permanent changes in perception. The vision will continue to improve as the lenses are worn. Everyone has one eye that is stronger than the other (or a dominant eye). This is worth bringing up (it matters more for presbyopic patients over the age of 53) because most people like to read books/phones/etc at about 15 inches from their face, but they also use their computer and its often around 30 inches from their face.

The new excimer from Alcon/WaveLight has features to enhance connectivity and decrease procedure times. A. Blended vision utilizes carefully selected conventional monofocal IOLs at the time of cataract surgery; one eye is corrected for distance and the other eye for near, providing excellent unaided vision following cataract surgery.
