A method for testing a laser device configured to emit pulsed, focused laser radiation includes providing an artificial eye body with a pattern that simulates a pupil and/or an iris structure. An irradiation test object is arranged above the pattern. The irradiation test object is separate from the eye body and is made of a material that is modifiable by the laser radiation. The laser radiation is applied to the irradiation test object according to a predefined application profile, so that a material modification that corresponds to the application profile is generated in the irradiation test object.

A system and method for insetting an intraocular lens in a patient's eye includes a light source for generating a light beam, a scanner for deflecting the light beam to form an enclosed treatment pattern that includes a registration feature, and a delivery system for delivering the enclosed treatment pattern to target tissue in the patient's eye to form an enclosed incision therein having the registration feature. An intraocular lens is placed within the enclosed incision, wherein the intraocular lens has a registration feature that engages with the registration feature of the enclosed incision. Alternately, the scanner can make a separate registration incision for a post that is connected to the intraocular lens via a strut member.

A method of treating a cataractous lens of a patient's eye includes generating a light beam, deflecting the light beam using a scanner to form a treatment pattern, delivering the treatment pattern to the lens of the patient's eye to create a plurality of cuts in the form two or more different incisions patterns within the lens to segment the lens tissue into a plurality of patterned pieces, and mechanically breaking the lens into a plurality of pieces along the cuts. A first incision pattern includes two or more crossing cut incision planes. A second incision pattern includes a plurality of laser incision each extending along a first length between a posterior and an anterior surface of the lens capsule.

The invention relates to apparatuses and methods for providing control data for an ophthalmological laser (12) of a treatment apparatus (10). The method includes ascertaining (S10) correction data for a planned refraction correction of a visual disorder of a cornea (16) from predetermined examination data, wherein the correction data includes a correction for a sphere value, a cylinder value and an axis value; determining (S12) adapted correction data based on a nomogram and the ascertained correction data, wherein the correction of the sphere value and/or the cylinder value and/or the axis value is adapted to the used treatment apparatus (10) by the nomogram, such that a refraction correction with the adapted correction data corresponds to the planned refraction correction, wherein the nomogram is ascertained by preceding treatment results with identical treatment apparatuses; and providing (S14) the control data, which is based on the adapted correction data.

Methods and apparatus can fit coverings to treat eyes. The treated eye may comprise a natural eye, for example an eye treated for refractive error with a contact lens, or an eye having an epithelial defect of the eye, such as an eye ablated with PRK refractive surgery. In many embodiments, the covering can be identified so as to provide improved flow of tear liquid under the covering. The covering can be identified based on an inner corneal curvature and an outer corneal curvature and one or more of a limbus sag height or a conjunctival sag height. The covering may form a chamber when placed on the eye to pump tear liquid under at least a portion of the covering. The covering may comprise an outer portion with rigidity to resist movement on the cornea and an inner portion to contact the cornea and provide an environment for epithelial regeneration. The covering may comprise a material having high oxygen permeability, for example silicone, with a wettable coating disposed on at least an upper surface of the coating.
