The present invention relates to methods and apparatus to improve human ophthalmic surgery patient wellness and surgical procedural outcome of both indicated cataract surgery and elective surgeries with the implantation of permanent standard intraocular lens (IOL) and new technology intraocular lens (NTIOL). The present invention further relates to measurement of refraction intra-operatively to validate or obviate the pre-operative calculations and thus selection of the IOL or NTIOL and allow for a correction to be made intra-operatively before the permanent IOL or NTIOL is implanted. Specifically, several embodiments of the invention pertain to a disposable, temporary Proxy Lens apparatus that are used for in situ refractive measurements, an Insertion Tool apparatus to manipulate the Proxy Lens within the optical path for the refractive measurement and a Refractometer apparatus to perform the refractive measurements. |
