Alcon® AcrySof® ReSTOR® IOL Intraocular Lenses
Biomaterial/Biomechanics Platform
The AcrySof® ReSTOR® IOL is based on long-proven technology. It uses the same AcrySof® hydrophobic lens material that has been implanted in over 23 million human eyes since 1991. It also features the same biomechanical advantages as the AcrySof® Single-Piece lens.
These qualities are important in optimizing refractive outcomes, particularly when providing a full range of uncorrected vision that may result in spectacle freedom.
Biomaterial
Studies on the original monofocal AcrySof® lenses have demonstrated a high level of material biocompatibility within the eye.¹,²,³ In addition, these studies have shown significantly less lens epithelial cell proliferation, which reduces the occurrence of anterior and posterior capsular opacification, and thus the need for YAG capsulotomies.
AcrySof® lenses also have low Nd:YAG rates4 in comparison with PMMA and silicone lenses.
Biomechanics
The AcrySof® ReSTOR® IOL also retains the biomechanical advantages of the AcrySof® Single-Piece design. The haptic design of AcrySof® lenses adapts and conforms to different capsular bag sizes and shapes.5 As a result, it remains well centered within the capsular bag. This quality is known as centration, and ensures that the lens stays where it was placed during surgery.
Another key advantage of AcrySof® lenses is the use of STABLEFORCEÔ haptics. This results in greater stability in the capsular bag. As a result, the lens provides both stability and centration.
