ANTI-PULFRICH MONOVISION OPHTHALMIC CORRECTION

Methods, systems, and ophthalmic devices are described for correcting a misperception of depth of a moving object. An example ophthalmic device may comprise a first lens having a first optical characteristic that increases a distance of a focal point of a first eye. The ophthalmic device may comprise a second lens having a second optical characteristic that decreases a distance of a focal point of a second eye. The second lens may have a third optical characteristic that reduces a misperception of a distance of an moving object.

Methods and systems for changing a refractive property of an implantable intraocular lens

A method of altering a refractive property of a crosslinked acrylic polymer material by irradiating the material with a high energy pulsed laser beam to change its refractive index. The method is used to alter the refractive property, and hence the optical power, of an implantable intraocular lens after implantation in the patient's eye. In some examples, the wavelength of the laser beam is in the far red and near IR range and the light is absorbed by the crosslinked acrylic polymer via two-photon absorption at high laser pulse energy. The method also includes designing laser beam scan patterns that compensate for effects of multiphone absorption such as a shift in the depth of the laser pulse absorption location, and compensate for effects caused by high laser pulse energy such as thermal lensing. The method can be used to form a Fresnel lens in the optical zone.
