  • Optical angular measurement system for ophthalmic applications and method for positioning of a toric intraocular lens with increased accuracy
    Patent number: 9307904
    Abstract: An ophthalmic system for use in performing angular measurements in relation to a patient's eye. The ophthalmic system can include an optical angular measurement device that can provide angular indicia by, for example, projecting an image of an angular measurement reticle onto a patient's eye or by superimposing an image of an angular measurement reticle onto an image of the patient's eye. The ophthalmic system can include an optical refractive power measurement device for providing desired angular orientations for ocular implants or for incisions. The ophthalmic system can be used, for example, to align a toric intraocular lens to a desired angular orientation.
