Accommodating lenses for cataracts ava milfs60050 dating18 info bu 1
When an accommodating IOL is implanted in the eye, the haptics of the IOL are positioned within the capsule of the eye's natural lens after the lens has been removed.
When the ciliary muscle contracts, this action loosens the zonules connecting the muscle to the lens capsule.
Instead of changing shape, an accommodative IOL moves slightly forward within the eye in response to focusing effort.
This forward movement is made possible by the "legs" (or haptics) of the accommodating IOLs, which are flexible.
When the focusing muscle relaxes (as the person looks across the room, for example), the accommodating IOL returns to its original position and provides for clear distance vision.
Some accommodating IOLs also have an optic (the central part of the IOL that focuses light) that can partially flex.
To see clearly up close, the ciliary muscle contracts and the lens becomes more curved.
It's also important for accommodating IOL candidates to have realistic expectations about the outcome of their surgery.In these cases, an accommodating IOL may not be able to improve near vision, but it will still function well as a monofocal (single power) IOL for good distance vision.Accommodating IOLs are premium intraocular lenses and cost significantly more than conventional IOLs.© 2008-2016 Ceatus Media Group LLC Images and text on this site belong to Ceatus Media Group.Copying or reproducing any text or graphics from this website is strictly prohibited by copyright law.
