What is Neuroadaptation after cataract surgery?
A process of neuroadaptation, the capability of the brain to adapt to changes, can be activated after Mu-IOL implantation to adjust the neurophysiology of the changes that are induced in the quality of the retinal image by light dispersion.
Which multifocal cataract lens is best?
Although there have been previous version of the AcrySof® IQ ReSTOR® IOL the +3.0 D add power is the best choice for true performance at all distances. It provides improved intermediate vision over the original AcrySof® IQ ReSTOR® IOL +4.0 D, with similar near and distance visual acuity.
Are multifocal lens implants worth it?
Existing systematic reviews have generally concluded that multifocal IOLs result in better uncorrected near vision and greater spectacle independence, but more unwanted visual phenomena such as glare and halos, compared to monofocal IOLs.
How long does it take for the brain to adjust to cataract surgery?
In order to fully appreciate the benefit of cataract surgery, it is often necessary to wait for your eyes and brain to adjust to your new lenses which may require one or two weeks.
Who should not get multifocal IOL?
If someone has an ocular comorbidity in either eye (eg, severe dry eye disease, irregular astigmatism, epiretinal membranes, macular degeneration), he or she is not eligible for a multifocal IOL. In my practice, this means that 50% of patients are ineligible.
What is Neuroadaptation model?
Neuroadaptation refers largely to the processes by which initial drug effects are either enhanced (i.e., sensitization) or attenuated (i.e., counteradaptation) by repeated AOD exposure. Drug-related responses (i.e., reinforcement) are modulated by the neuroadaptive changes that occur with AOD exposure.
How can I enhance adaptation following implantation of Multifocal IOLs?
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.
Can multifocal neuroadaptation help the brain?
Multifocal Neuroadaptation: Can Training Help the Brain? Studies in multiple disciplines now suggest that patients may adapt to altered input more quickly and completely with outside help. In the ongoing struggle to compensate for the visual deficits caused by presbyopia, multifocal intraocular lenses have become a popular option.
Does visual neuroadaptation play a role in intraocular lens implantation?
Visual neuroadaptation is believed to play an important role in determining the final visual outcomes following intraocular lens (IOL) implantation.
How do multifocal IOLs affect the brain?
By altering the characteristics of the images striking the retina and simultaneously exposing the brain to an unfamiliar visual experience, multifocal IOLs have created new challenges for both patients and ophthalmologists.
