Methods of correcting vision for presbyopia, including remodeling a stroma with a laser to create an intracorneal shape, where the corneal shape includes a central region with a thickness that is about 50 microns or less measured from an extension of a shape of a peripheral region of the corneal shape, wherein remodeling a portion of the stroma increases a curvature of a central portion of the anterior surface of the cornea with a central elevation change for near vision.

The present invention generally relates to an apparatus and processes for preventing, delaying or ameliorating presbyopia. More particularly, the present invention relates to processes and apparatus for ablating cells in the transitional zone of the crystalline lens of the eye so that onset or progression of presbyopia or one or more symptoms is delayed or prevented.

A method for generating cut surfaces in the cornea of an eye in order to correct ametropia using an apparatus. The method includes providing the apparatus including a laser unit, which focuses pulsed laser radiation into the cornea and moves the focused radiation in the cornea to generate cut surfaces, and a control unit, which controls the laser unit for generating cut surfaces.

The method includes forming at least two mutually spaced apart cut surfaces as opening cuts by application of the pulsed laser radiation from the laser unit, each opening cut extending from an anterior corneal surface into the cornea and forming a further cut surface as a relieving cut by application of the pulsed laser radiation from the laser unit, which relieving cut extends from the anterior corneal surface into the cornea. The position and shape of the relieving cut is selected such that the relieving cut contributes to the correction of the ametropia of the eye.

The present invention generally relates to apparatus and processes for preventing or delaying cataract. More particularly, the present invention relates to processes and apparatus for ablating epithelial cells in the germinative zone or the pregerminative zone of the crystalline lens of the eye so that onset or progression of cataract or one or more symptoms is delayed or prevented.

A system and method for increasing the amplitude of accommodation and/or changing the refractive power of lens material of a natural crystalline lens is provided. Generally, there is provided methods and systems for delivering a laser beam to a lens of an eye in a plurality of patterns results in the increased accommodative amplitude and/or refractive power of the lens. There is further provided a system and method of treating presbyopia by increasing both the flexibility of the human lens and the depth of field of the eye.

Apparatus and methods of treating a hard lens region of an eye with a laser where one method includes identifying a boundary of the hard lens region, selecting a laser-parameter to enable a photodisruptive procedure in the hard lens region and to control a spreading of bubbles in the hard lens region, modifying a mechanical property of a posterior portion of the hard lens region in a proximity of the identified boundary by the photodisruptive procedure, and modifying a mechanical property of a portion anterior to the modified posterior portion of the hard lens region by the photodisruptive procedure. The laser bubbles can be applied to form incisions which are non transverse to an axis of the eye and intersect the lens fibers.

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.
