A device for producing control data for a laser device for the surgical correction of defective vision. The device produces the control data such that the laser emits the laser radiation such that a volume in the cornea is isolated. The device calculates a radius of curvature R.sub.CV* to determine the control data, the cornea reduced by the volume having the radius of curvature R.sub.CV* and the radius of curvature being site-specific and satisfying the following equation: R.sub.CV*(r,?)=1/((1/R.sub.CV(r,?))+B.sub.COR(r,?)/(n.sub.c?1))+F, wherein R.sub.CV(r,?) is the local radius of curvature of the cornea before the volume is removed, n.sub.c is the refractive index of the material of the cornea, F is a coefficient, and B.sub.COR(r,?) is the local change in refractive force required for the desired correction of defective vision in a plane lying in the vertex of the cornea, and at least two radii r1 and r2 satisfy the equation B.sub.COR(r=r1,?)?B.sub.COR(r=r2,?).

In certain embodiments, an ophthalmic surgical system for adjusting a dimension of an eye includes a camera and a computer. The camera generates a surgical image of the eye in contact with a patient interface, which distorts the cornea. The surgical image includes the pupil with a real pupil diameter. The computer accesses a diagnostic image of the eye with the cornea having a natural curvature. The natural curvature affects the real pupil diameter to yield a diagnostic pupil diameter of the diagnostic image that is different from the real pupil diameter of the surgical image. The computer adjusts the real pupil diameter of the surgical image using an eye model to yield a refracted pupil diameter that takes into account the curvature of the cornea and uses the refracted pupil diameter to compensate for the difference between the diagnostic and real pupil diameters.

A system for ophthalmic surgery on an eye includes: a pulsed laser which produces a treatment beam; an OCT imaging assembly capable of creating a continuous depth profile of the eye; an optical scanning system configured to position a focal zone of the treatment beam to a targeted location in three dimensions in one or more floaters in the posterior pole. The system also includes one or more controllers programmed to automatically scan tissues of the patient's eye with the imaging assembly; identify one or more boundaries of the one or more floaters based at least in part on the image data; iii. identify one or more treatment regions based upon the boundaries; and operate the optical scanning system with the pulsed laser to produce a treatment beam directed in a pattern based on the one or more treatment regions.

A system/method allowing personalized ex vivo customization of a generic ophthalmic lens blank (OLB) or ophthalmic lens with known diopter (OKD) based on localized field-measured patient characteristics is disclosed. The OLB is composed of an acrylic material that has been infused with an ultraviolet (UV) absorbing compound rendering it amenable to customized spatial modification (CSM) of its refractive index via the use of pulsed laser radiation (PLR). The CSM of refractive index eliminates the need for remote laboratory fabrication of a customized intraocular lens (IOL) for the patient. The OLB is retained within a secured lens container (SLC) providing for precise physical orientation of the OLB haptics and OLB lens structure with respect to the application of PLR to the OLB. The SLC contains a lens filler material (LFM) covering the OLB and is hermetically sealed after the OLB has been positioned within the SLC interior and prior to sterilization of the SLC+OLB combination.

An ophthalmological laser system for photodisruptive irradiation of ocular tissue, including a crystalline lens or a cornea. The system includes an ultra-short pulse laser, the radiation of which is focusable as illumination light via an illumination beam path including a scanner unit and focusing optics. A control unit is programmed to execute determining irradiation control data for photodisruptions at irradiation points in an interior of the ocular tissue distributed three-dimensionally and non-equidistantly to create at least one predetermined target incision. The laser system then irradiates the ocular tissue according to the determined irradiation control data.

A system and apparatus for increasing the amplitude of accommodation and/or changing the refractive power and/or enabling the removal of the clear or cataractous lens material of a natural crystalline lens is provided. Generally, the system comprises a laser, optics for delivering the laser beam and a control system for delivering the laser beam to the lens in a particular pattern. There is further provided a range determining system for determining the shape and position of the lens with respect to the laser. There is yet further provided a method and system for delivering a laser beam in the lens of the eye in a predetermined shot pattern.

A method for adjusting the refractive power of a fluid-filled intraocular lens implanted into a patient's eye. The method comprises selecting a pattern to cause a flattening of the intraocular lens or an increase in curvature of the intraocular lens, and ablating the pattern, onto either an optical element of the intraocular lens or a flexible element of the intraocular lens, to alter either one or both of a refractive power and an amplitude of accommodation of the intraocular lens. The ablating occurs while the intraocular lens remains implanted in the patient's eye. The ablating maintains the integrity of a fluid-filled interior cavity defined between the optical element and the flexible element, but causes the flattening of the intraocular lens or the increase in curvature of the intraocular lens.
