Supplementary Intraocular Lens
A method is disclosed to place supplemental IOLs in the anterior chamber, posterior chamber or both, in combination with the eye's natural lens or a separate, implanted artificial lens.
1 . A method for providing vision adjustments and protection to a principal lens present in the posterior chamber of a mammalian eye, said principal lens being a natural lens or an artificial intraocular lens (IOL), said method comprising the steps of:
determining the type of adjustment or protection needed for said principal lens;
providing at least one supplementary lens selected to provide the desired adjustment or correction; and
inserting said at least one supplemental lens into the posterior chamber proximate to said principal eye.
2 . The method of claim 1 wherein said at least one supplementary lens is tinted to provide protection from ultraviolet radiation.
3 . The method of claim 2 wherein said tint is yellow.
4 . The method of claim 1 further comprising the step of inserting a second supplemental lens in the anterior chamber of said eye.
5 . The method of claim 4 wherein said second supplemental lens is a multifocal lens.
6 . The apparatus as recited in claim 4 wherein said second supplemental lens is a toric lens.
7 . The method of claim 4 wherein said second supplemental lens is an aspherical lens.
8 . A method for providing vision adjustments and protection to a principal lens present in the posterior chamber of a mammalian eye, said principal lens being a natural lens or an artificial intraocular lens (IOL), said method comprising the steps of:
determining the type of adjustment or protection needed for said principal lens;
providing at least one supplementary lens selected to provide the desired adjustment or correction; and
inserting said at least one supplemental lens into the anterior chamber proximate to said principal eye.
9 . The method of claim 8 wherein said at least one supplementary lens is tinted to provide protection from ultraviolet radiation.
10 . The method of claim 9 wherein said tint is yellow.
11 . The method of claim 8 further comprising the step of inserting a second supplemental lens in the anterior chamber of said eye.
12 . The method of claim 8 wherein said second supplemental lens is a multifocal lens.
13 . The apparatus as recited in claim 8 wherein said second supplemental lens is a toric lens.
14 . The method of claim 8 wherein said second supplemental lens is an aspherical lens.
