TOOLS AND METHODS FOR THE SURGICAL PLACEMENT OF INTRAOCULAR IMPLANTS

摘要

Provided herein is a measurement tool for implantable non-spherical asymmetric optics comprising a viewable, rotatable angular caliper superimposable over an image of an eye. Also provided are methods for optimally placing non-spherical asymmetric optics in an eye of a patient and for correcting post-operative astigmatism in a patient having cataract surgery. The measurement tool is useful to plan the optimal correct surgical placement of a non-spherical asymmetric optic, e.g., a toric intraocular implant or a toric intraocular contact lens, in the eye. By superimposing the measurement tool over a corneal topographic image, an optimal positioning of the non-spherical asymmetric optic can be effected in an optical zone of interest. Correct placement or re-placement at least minimizes astigmatism in post-operative vision. Also provided are computer program products and computer readable media comprising modules and methods for data entry, lens selection and surgical planning utilized to practice the methods provided herein.
