This amazing feat of neuroplasticity actually allows the patient to achieve relatively normal eye function, without bifocal contacts or glasses. Monovision counters the deterioration of the ability to see up close but also causes dramatic visual distortions. 3. While most adapt almost immediately, others take a longer period, from several weeks, to make the adjustment. As you are probably aware, monovision correction is the process by which the dominant eye is adjusted for distance vision, and the non-dominant eye is adjusted for close-up activities including reading or working on the computer. This goes back to monovison contacts be a normal lens. If this doesn't work, your mother could always wear glasses to try to balance the correction. Does it work with everybody?

It can take time and patience to adapt to this type of vision correction. The main advanage of contact lens is its an option for anyone willng to try. Problems with this technique arises because it basically hampers or compromises binocular vision. "An engineer is trained to use precise acuity; if you alter their visual apparatus in any way, they'll be miserableand they'll let you know! ", Richard L. 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. Do I know exactly how much it will improve the outcome? Thousands of clinical trial participants and customers have reported significant improvement in their vision performancean average of two lines of visual acuity, and a 100-percent increase in contrast sensitivity." The other reason is some people only need to wear one contact (more on this later). Monovision contact lenses are used to correct for distance and near vision. 2.

These patients may have trouble viewing objects up-close but monovision correction is the perfect solution! "Also, many surgeons are wary of operating on people in visually de-manding professions such as engineering," Dr. Kershner notes. Some may find that monovision comes naturally to them and barely experience any change in lifestyle. As you are probably aware, monovision correction is the process by which the dominant eye is adjusted for distance vision, and the non-dominant eye is adjusted for close-up activities including reading or working on the computer. 5 What kind of eye surgery does Blended Vision use? 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 average improvement in near vision was 1.8 lines; the range was 0.8 to three lines. 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. "We suspect that being able to quantify how dominant one eye is relative to the otheri.e., neural competitivenessmay help us to predict better how patients will do with both monovision and multifocality," he says. "I believe premium IOLs are an important indication for this technology, as are post-corneal refractive surgery patients with a small residual refractive error and patients with low levels of naturally occurring ametropia and early presbyopia. Reproduction in whole or in part without permission is prohibited. "Patients who at first notice a color shift after surgery usually report that it's disappeared when asked about it again a few weeks or months later. Not every question will receive a direct response from an ophthalmologist.

One available system designed to enhance adaptation following implantation of multifocal IOLs is an Internet-based program offered by RevitalVision (using technology pioneered by its predecessor, NeuroVision), based in Lawrence, Kan.

Sometimes, ones distance vision would also experience lack of sharpness, because only the dominant eye is fitted with distance vision lens. Key to Success: Communication Mr. Sheil says this type of neuroadaptive training has also been shown to improve near vision in presbyopic patients.
