There are three different types of IOLs currently on the market: implanted collamer lenses, iris-fixated lenses, and angle-supported lenses. These are all situated slightly different within the eye. Angle-supported lenses rest in the irido-corneal angle, iris-fixated lenses hold on to the iris, and implanted collamer lenses have small structures (haptics) that fit under the iris to hold them in place.<
