This follow-up study found anterior capsule opacification development and anterior capsule retraction to be more frequent 3 years after cataract surgery when an IOL with interrupted sharp optic edge at the optic–haptic junction is implanted, compared with an IOL with a continuous edge.
Multifocal IOLs with a trifocal diffractive optic design are available outside of the United States. They provide good visual acuity for distance, intermediate, and near and appear to provide slightly better intermediate vision than bifocal diffractive multifocal IOLs.
Fluid-based accommodating IOL technology achieved “true accommodation” in a pilot study. A multicenter study of the lens is ongoing.
A warm viscoelastic technique aids in the intraoperative delivery and unfolding of a hydrophobic acrylic IOL during cataract surgery.
Modifications to a reusable injector system have reduced resistance between the plunger tip and the IOL, creating a smoother delivery of the lens into the eye.
An optometrist in British Columbia has developed an IOL that his company’s website says “is capable of restoring quality vision at all distances, without glasses, contact lenses or corneal refractive procedures, and without the vision problems that have plagued current accommodative and multifocal [IOL] designs.”
