Appeal No. 2005-1945 Page 2
Application No. 09/777,510
BACKGROUND
The appellants' invention relates to implantable phakic intraocular lenses (IOLs)
suitable as correction lenses together with the intact natural crystalline lens. The
appellants' lenses are provided with a posterior surface, which admits a more
anatomical fit in the posterior chamber of the eye, thereby minimizing the risks of
disturbing the natural lens (specification, p. 1). A copy of claims 2 to 19, 25 to 34 and
48 to 50 is set forth in the appendix to the appellants' brief. Claim 1 reads as follows:
An intraocular correction lens adapted for implantation in the posterior
chamber of an eye between the iris and the intact natural lens, comprising
a centrally located optical part capable of providing an optical correction
and
a peripherally located supporting element capable of maintaining said
optical part in said central location,
wherein said optical part and said support element together have a
concave posterior surface which is part of a non-spherical surface that is rotation
symmetric around the optical axis of said optical part, wherein the intersection
between said non-spherical surface and any plane containing the optical axis
represents a flawless curve free from discontinuities and points of inflection.
