Accommodating power

This may be related to the finding that those who received accommodative IOLs also appeared to have a higher rate of posterior capsular opacification (thickening and clouding of the tissue behind the IOL). Further research on accommodative IOLs is required before we can draw conclusions on their effectiveness and safety compared to monofocal IOLs Quality of the evidence Overall the quality of the evidence was low or very low with the exception for the findings on near vision at six months.

Based on these measurements, an accommodating IOL prototype was built and implanted in monkeys' eyes.

Pharmacologic agents were used to achieve ciliary relaxation and spasm.

An implantable measuring device was constructed to simulate the lens action.

The device was implanted in monkey eyes to measure the various parameters involved with such IOLs.

Joshua Ben-nun is the inventor of this intraocular lens and has a proprietary interest in the intraocular lens used in this study.

Nu Lens holds the proprietary rights for the development of this concept of accommodative intraocular lens.

This is a problem for most people in their 40s or 50s.

For best optical performance, the lens must be transparent. It is more common with increasing age, and is a common cause of visual impairment.

Accommodation is achieved through the contraction of ciliary muscles, which results in an increase in curvature and a forward shift of the natural lens in the eye.

Accommodation declines with increasing age due to a decrease in lens elasticity and a reduction in ciliary muscle contraction, resulting in difficulty in near vision (presbyopia).

To overcome the loss of accommodation after cataract surgery, various strategies have been tried with variable success.
