AS-IOL

Ocular lens opacification usually developed with advancing age. In order to improve eye vision, natural lens affected with cataract is removed and an intraocular lens is implanted inside the capsular bag. For eye lens removal, nowadays the most used technique consists in breaking it in multiple particles and removing those particles by “phacoemulsification” method. In this surgery procedure the lens is break up into tiny pieces because of the high mechanical strength triggering high turbulence conditions. Since there is physical manipulation with several surgical instruments inside the anterior chamber of the eye, it is essential to be very careful to avoid irreparable damage of ocular tissues. To achieve this, a viscoelastic fluid as protector agent is used, being injected at the beginning of the process, and is attached protecting corneal endothelium during surgery. After “phacoemulsification”, a new intraocular lens is implanted into the eye.


The objective of AS-IOL Aspheric Lens is to optimize the optical quality, therefore a global optimization has been performed considering a combination of the foveal vision optical quality (on axis) and extrafoveal (outside axis), evaluating ocular aberrations through a ray tracing procedure, and maximizing optical quality with optimization techniques. The result has triggered the production of lenses with aspheric surfaces optimized for the whole of the patients, considering biometric data measured previously in pseudophakic patients as well as pre- and post- surgery databases. Regarding to the retinal image quality that these lenses provide, recent scientific studies have proved that are suitable to provide, systemically, a higher image quality and a higher stability of such image quality.
AS-IOL lens is manufactured with a hydrophilic material that contains a natural chromophore covalently bound that blocks ultraviolet light and filters blue light just as the eye lens works on a young person. This chromophore is identical to the one found in the 3-hydroxy kynurenineglucoside, which is the molecule responsible of UV block and blue light filtering in the eye lens of a young person.
