Research accommodating lens

In a new study, researchers looked to the fish's retinal structure to inform the design of a contact lens that can adjust its focus.The presence of myopia, or nearsightedness, significantly affects the muscles used in focusing the lens of the eye--a finding with important implications for the development of "accommodating" implanted intraocular lenses (IOLs) that can adjust to different visual distances, reports a study in the January issue of Optometry and Vision Science, official journal of the American Academy of Optometry.(2) If pseudophakic eyes can accommodate, how long does this accommodation last? This is a systematic review of randomized and nonrandomized controlled trials that have compared different IOLs in accommodation using subjective and objective methods of testing accommodation.All peer reviewed randomized and nonrandomized controlled trials that compared different IOLs in accommodation were included.Because there is only one point at which the light enters the lens, there are not as many issues with glare or halos as there can be with some multifocal lenses (see below).Because this lens can correct only one focal distance, it won’t suit those who want to avoid using glasses (for instance, people who play sport and find glasses an encumbrance or do a wide variety of activities requiring near and far distance focus).There was evidence of pseudophakic accommodation up to 12 months postoperatively for AIOLs (mostly 1CU): subjective accommodation [95% confidence interval (CI), 0.36–0.98], objective optic shift (95% CI, 0.12–0.76).However, accommodation decreased at 12 months postoperatively (95% CI, 0.55–1.00).

that holds promise of revolutionizing the treatment of cataracts and presbyopia, based on early phase discoveries by polymer physicist Murugappan Muthukumar and former graduate student Ben Mohr regarding the fundamental science of proteins in the lens of the human eye.

Insertion of an intraocular lens for the treatment of cataracts is the most commonly performed eye surgical procedure.

The procedure can be done under local anesthesia with the patient awake throughout the operation.

Here, with the help of Dr Stevens and Brendan Moriarty, a leading ophthalmic surgeon (and special adviser to NICE), we look at the various lenses on the market to help you make the right choice for you...

    One player has the dark pieces; the other has the light pieces. If the adjacent square contains an opponent's piece, and the square immediately beyond it is vacant, the piece may be captured (and removed from the game) by jumping over it.
