This implant, also known as an intraocular lens, (IOL) is an artificial lens implanted in the eye in place of the eye’s clouded crystalline lens during cataract surgery.
Before the advent of cataract implants, the only way to replace focusing power was to prescribe thick “coke bottle” glasses. In 1949, cataract surgery advanced tremendously when English ophthalmologist Harold Ridley developed the first intraocular lens implant.
Several types of IOLs exist, but they all share the same basic construction, which usually consists of a round lens called the optic and two arms, called haptics. These keep the lens in place and centered in the eye. Since 1949, different materials have been used to make IOLs.
The most widely used IOL materials today include silicone and a soft, foldable acrylic called AcrySof® IOL material. AcrySof® lenses can be folded like a taco and implanted into the eye through a very small incision, where it gently unfolds into its permanent position. These smaller incisions often do not require sutures, allowing for faster recovery with better results.
There are various vision correction implants currently being used during cataract surgery.
Some of these implants include::
