Answer: Although some people cannot adjust to monovision, most who have adapted to this distance vision in one eye and near vision in the other eye will do well over time. New Penn research reports that monovision, a common prescription lens correction to mitigate this issue, can cause dramatic misperceptions of depth and 3D direction for objects in motion. With monovision correction, the non-dominant eye is adjusted depending on whether or not you were far or near-sighted. You mention the spherical refraction, -0.5D and -1.75D, but astigmatism might aso be having an impact. Obviously, there will be an adjustment period. 00:0112:45.

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. "Our training system is designed to enhance neuroadaptation by making the visual system analyze information presented using Gabor patches," explains Brendan Sheil, CCO of RevitalVision.

As a result I almost categorically avoid implanting multifocal lenses in these patients. Many ophthalmologists haven't had to devote too much time to worrying about the neurological half of the visual systemuntil now. "Slow adaptation probably results from neural plasticity, which is long-term alteration in anatomic connections or synaptic properties due to neuronal activity or injury. It can be difficult for some patients to adjust to monovision. Some may find that monovision comes naturally to them and barely experience any change in lifestyle. However, we will follow up with suggested ways to find appropriate information related to your question. I've worn monovision contact lenses (wearing one lens for distance vision and one for near) for 20-plus years and just had monovision cataract surgery.
