Multifocal or accommodating intraocular lens

This is why they are classified as "accommodating IOLs." Both lenses are manufactured and distributed by Bausch Lomb.

Accommodation is made possible by the lens inside the eye and the circular muscle that surrounds the lens, called the ciliary muscle.

He noticed that it was well tolerated and realized that plastic lens implants of the same material could be formed for eye lens replacement after cataract surgery.

The original IOLs where made of rigid PMMA (plastic).

Crystalens and Trulign Toric are premium intraocular lenses (IOLs) that correct presbyopia as well as common refractive errors, enabling an expanded range of clear vision and a decreased need for eyeglasses after cataract surgery, compared with surgery performed with conventional monofocal IOLs.

Currently, Crystalens and Trulign Toric IOLs are the only FDA-approved presbyopia-correcting IOLs for cataract surgery that improve near vision by a focusing process called accommodation.

Intraocular lenses, or IOLs, are implantable lenses that are used to replace the natural lenses of the eyes when they have become damaged.

Scientists originally designed IOLs to treat cataracts.

Without a lens within it the eye is widely out of focus and remains legally blind.An intra ocular lens once inserted can be forgotten about by the patient and restores the eye to the most nearly natural state.Traditional IOLs are monofocal, meaning they offer vision at one distance only (far, intermediate or near).The cataract lens implants give a much higher level of optical quality and lifestyle convenience than the thick glasses so we always implant an intraocular lens at the time of cataract surgery if it is safe to do so.During WWII, Sir Harold Ridley, was caring for a pilot with a small piece of a plane’s PMMA plastic windshield forced inside his eye.
