The embodiments disclosed herein include improved toric lenses and other ophthalmic apparatuses (including, for example, contact lens, intraocular lenses (IOLs), and the like) and associated method for their design and use. In an embodiment, an ophthalmic apparatus (e.g., a toric lens) includes one or more angularly-varying phase members comprising a diffractive or refractive structure, each varying the depths of focus of the apparatus so as to provide an extended tolerance to misalignment of the apparatus when implanted in an eye. That is, the ophthalmic apparatus establishes an extended band of operational meridian over the intended correction meridian.

A method of modifying a refractive profile of an eye having an intraocular device implanted therein, wherein the method includes determining a corrected refractive profile for the eye based on an initial refractive profile, identifying one or more locations within the intraocular device based on the corrected refractive profile, and directing a pulsed laser beam at the locations to produce the corrected refractive profile. A system of modifying an intraocular device located within an eye, wherein the system includes a laser assembly and a controller coupled thereto. The laser assembly outputs a pulsed laser beam having a pulse width between 300 picoseconds and 10 femtoseconds. The controller directs the laser assembly to output the pulsed laser beam into the intraocular device. One or more slip zones are formed within the intraocular device in response thereto, and the slip zones are configured to modify a refractive profile of the intraocular device.

Techniques and mechanisms for determining a direction of gaze by a user of an ophthalmic device. In an embodiment, at least a portion of a magnetic field is generated by one of the ophthalmic device and an auxiliary reference device while the ophthalmic device is disposed in or on an eye of the user, and while the auxiliary reference device is adhered on the user's skin or under a surface of the skin.

In another embodiment, the ophthalmic device stores predetermined reference information which corresponds various magnetic field signal characteristics each with a different respective direction of gaze. Based on the sensor information and the reference information, a controller of the ophthalmic device determines a direction in which the eye of the user is gazing.
