Benefits of technology

The hydrophobic-hydrophilic or hydrophobic-super-hydrophobic interface minimizes opacification, enhancing the stability and visual performance of dual optic and piggyback intraocular lens systems by reducing interlenticular opacification.

Problems solved by technology

When trauma, age, disease or other malady cause an individual's natural crystalline lens to become less transparent, vision deteriorates because of the diminished light which can be transmitted to the retina.
While such two lens systems can improve visual performance, recent articles have suggested that various types of these lens systems may be susceptible to the development of interlenticular opacification (ILO).

Embodiment Construction

[0017]The present invention is predicated upon the provision of at least one intraocular lens (IOL) and preferably two IOLs that have a coating for aiding in the prevention of opacification, particularly interlenticular lens opacification (ILO). The IOL[s] typically form an intraocular lens system such as a dual optic or piggyback lens system. The coating is typically formed of a hydrophilic or super-hydrophobic material for aiding in the resistance or prevention of ILO.

[0018]Unless otherwise specifically stated, percentages of materials as used herein are weight percentages (w / w).

[0019]FIG. 1 illustrates an exemplary intraocular lens system 10 in accordance with an aspect of the present invention. The system 10 includes a first intraocular lens 12 and a second intraocular lens 14. As used herein, the terms “first” and “second” as they are used to indicate a lens of the system are merely used to indicate one of the lenses as opposed to the other. These terms are not intended to sugg...

Abstract

The present invention is directed to an intraocular lens, an intraocular lens system and a method of producing and / or implanting the lens or system in an eye wherein at least one intraocular lens includes a coating that aids in resisting interlenticular opacification (ILO). The material of the coating is preferably hydrophilic or super-hydrophobic.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application is a divisional of U.S. patent application Ser. No. 12 / 874,863 filed Sep. 2, 2010 (now allowed) claims priority under 35 U.S.C. §119 to U.S. Provisional Patent Application Ser. No. 61 / 239,974, filed Sep. 4, 2009, the entire contents of which are incorporated herein by reference.TECHNICAL FIELD OF THE INVENTION[0002]The present invention relates to an intraocular lens, an intraocular lens system and a method of producing and / or implanting the lens or system in an eye wherein at least one intraocular lens includes a coating that aids in resisting interlenticular opacification (ILO).BACKGROUND OF THE INVENTION[0003]The human eye functions to provide vision by transmitting and refracting light through a clear outer portion called the cornea, and further focusing the image by way of a lens onto the retina at the back of the eye. The quality of the focused image depends on many factors including the size, shape and length of the...
