Page 4 of 21An increasingly important goal of modern cataract and implant surgery is to obtain the mostdesirable outcome for the patients, thus contributing to spectacle-free vision and highest qualityof life.The ideal state of the human phakic eye without any refractive error is known as emmetropia;Rays of light perfectly focused from an infinitely distant object onto the fovea withoutaccommodation 1 .Refractive power of the eye is determined by three main parameters: power(s) of the cornea,power of the crystalline lens and axial length of the eye. Incompatibility between theseparameters leads to various types of refractive errors known as myopia and hyperopia.The natural crystalline lens has the ability to accommodate in order to maintain a clear image(focus) of an object whatever the distance from the eye. At about the age of 40, the lens becomesless flexible and accommodation is lost gradually 2 , making close-range activities increasinglydifficult. This is called presbyopia. Once presbyopia has been diagnosed reading glasses orcorrective contact lenses are necessary to maintain near vision.With age, a normal crystalline lens opacifies (cataract) disabling the eye in generating a clear,well contrasted image. The only therapeutic solution to this problem is surgical replacement ofthe crystalline lens with an intraocular lens (cataract surgery).New technologies in IOLs optic designs provide for better options for cataract patients to correcttheir visual deficits and to live their lives without visual aids.The clinical demand for a solution to presbyopia is very high, as presbyopia afflicts the majorityof the world’s adult population.Implantation of a bifocal IOL, like SeeLens MF, with a bifocal aspheric refractive/diffractivestructure, pupil size dependence and asymmetrical light distribution provides for a satisfactory1 Diepes H. 2004, Refraktionsbestimmung2 Lang G.K., Spraul C.W.
