Accommodating intraocular lenses cost
Neuroadaptation is necessary for the brain and eye to ’filter out‘ the blurred, unwanted image and ’see‘ the sharper, focused image.Initially some patients may experience misty vision – bringing objects into focus may take longer and vision can be dimmer because only part of the light entering the eye is in focus. Some patients may have issues with stereopsis, reduced visual field on the myopic eye as well as night vision symptoms such as halos.In spite of these, spectacle independence can be achieved approximately 80% of the time and patient satisfaction ranges from 70-90% in various studies.
In the eye, the IOL unfolds itself and it is placed in the capsular bag.
So the fovea (retina) receives two images simultaneously.
(This is different from progressive spectacles where the patient looks through a predetermined part of the spectacle lens with powers allocated for that desired working distance).
In pseudo-accommodation, these IOLs do not change shape in order to change the total optical power of the eye i.e. They have 2-3 different optical powers built into the optics.
The multifocal optic splits the inbound light into two, usually 65%-35% or a 50%-50% for distance and near vision respectively.
