Claim Text:
1. An ophthalmic surgical method for determining a desired intraocular lens for insertion into a prosthetic implant device implanted in a natural capsular bag of an eye after removal of a cataract, the ophthalmic surgical method comprising: introducing the prosthetic implant device into the eye, wherein introducing the prosthetic implant device into the eye comprises allowing the prosthetic implant device to elastically resume a pre-folded shape, the prosthetic implant device comprising: using the exterior contour to stabilize and center at least a portion of the prosthetic implant device in a capsulorhexis; using the prosthetic implant device to maintain a volume of the natural capsular bag; performing a pseudophakic refraction to determine an effective lens position (ELP) of the refractive surface of the posterior end at least partially based on the refractive power of the refractive surface of the posterior end; determining a refractive power of the desired intraocular lens for implantation into the prosthetic implant device, the determination at least partially based on the determined effective lens position (ELP) of the refractive surface of the posterior end of the prosthetic implant device; selecting a first intraocular lens based on the determined refractive power of the desired intraocular lens; and inserting the first intraocular lens into the channel through the anterior opening, the first intraocular lens comprising haptics engaging the sidewalls.
