Tetraflex accommodating intraocular lens

One hundred percent achieved a BCDVA, 89.3% achieved a DCNVA, and 74.1% achieved a UCNVA of 20/40 or better at 6 months after surgery. For nearly two decades, “presbyopia-correcting” intraocular lenses (IOLs) have been available to post-cataract surgery patients, but for a variety of reasons they have garnered only modest interest.

At 6 months and later, 98.7% had a BCDVA of 20/40 or better.

In the bilaterally implanted series, at 1 month after surgery, all patients had at least 1 D of accommodative ability; 96% had at least 2 D at 6 months.

As a result, currently approved accommodating lenses typically can’t provide a full range of vision.

IOL developers continue to investigate new accommodating designs in hopes of gaining enough accommodation to provide sharp vision at all distances.

At 6 months after surgery, 63% of all cases achieved a DCNVA of 20/40 or better.

Virtually all of the patients had at least 1 diopter (D) of accommodative amplitude (98% at 1 month; 100% at 3 and 6 months); 75.7% had at least 2 D at 6 months after surgery.In May 2013, the FDA approved a toric version of the lens, called Trulign.(Toric designs correct astigmatism.) THE FAILED Synchrony (developed by Visiogen) was a mechanical accommodating IOL with two lenses that moved closer or farther apart to change focus.This design strategy trades off some of the benefits of seeing through a single zone in order to have a greater range of focus. While many multifocal patients can read without glasses, their distance vision may not be as sharp as it might be with a monofocal IOL.Multifocal patients often complain of seeing glare and halos, especially at night, in the first few months after surgery.THE STALLED Sapphire Autofocal (Elenza, Inc.) is billed as the first “electro-active” accommodating IOL.
