Patent ID: 7719668

Claim:
A method of measuring an optical power of an intraocular lens, comprising: generating illumination light; coupling said illumination light into a fiber-optic light delivery system; transmitting illumination light from a transmit/receive end of said fiber-optic light delivery system; collimating light transmitted from said transmit/receive end of said fiber-optic light delivery system; disposing an intraocular lens to be measured in a path of illumination light that has been collimated; reflecting illumination light that passed through said intraocular lens-to-be-measured from a reflecting surface back through said intraocular lens-to-be-measured to be coupled into said transmit/receive end of said fiber-optic delivery system; detecting at least some of said light coupled into said transmit/receive end of said fiber-optic delivery system as said reflecting surface is varied in position relative to said intraocular lens to be measured; determining a position of said reflecting surface relative to said intraocular lens to be measured based upon a substantially maximum of a detected light signal; and determining an optical power of said intraocular lens to be measured based on said determined said relative position of said reflecting surface.
