portion 44 has a curvature SRfr and the lens body portion 42 has an outer curvature
SRfr2 (SRo) and an inner curvature SRi.
A third embodiment of a positive intraocular refractive correction lens is shown in
Figures 15-17. The intraocular refractive correction lens 50 is defined by an
oval-shaped lens body portion 52 and a circular shaped lens portion 54. The detailed
curvature of the intraocular refractive correction lens is shown in Figure 17. An example
of this particular lens is given in the table in Figure 18 with the designations R1-R8
corresponding to Figure 17.
A third embodiment of a negative intraocular refractive correction lens is shown
in Figures 20-21. The intraocular refractive correction lens 70 is defined by an
oval-shaped lens body portion 72 and a circular shaped lens portion 74. The important
feature of this embodiment is the circular groove G provided in the lens body portion 72
surrounding the lens portion 74. The circular groove G allows for circulation of fluid
inside the eye. Further, the groove G can be used for lens manipulation during surgery,
and facilitates the equalization of intraocular pressure.
An embodiment of an intraocular refractive correction lens 80 having a lens body
portion 82 and lens portion 84, is shown in Figures 22-24. In this embodiment, an air
