A method for operating a data processing system to provide an estimate of a vault value for a PIOL to be inserted in a patient, a system for predicting the vault that will be realized for an implant, and computer readable medium that includes instructions that cause a data processing system to implement the method when the instructions are executed by a data processing system are disclosed. The method includes causing the data processing system to receive ultrasound-based anatomical measurements of the patient's eye, causing the data processing system to receive parameters specifying a power and size for the PIOL; and utilizing a calibrated model of a human eye to predict the vault based on the anatomical measurements and the parameters specifying the power and the size for the PIOL.

System of determining the correct implantable collamer lens size from ultrasound images of the eye

A treatment apparatus for surgical correction of presbyopia or defective eyesight in an eye of a patient. The treatment apparatus includes a laser device configured to treat lens tissue of the eye by irradiation of pulsed laser radiation with the laser radiation being focused on target points arranged in a pattern within the lens. An interface supplies measurement data on parameters of the eye and/or defective-eyesight data on the eyesight defect to be corrected in the eye, and defines a volume located within the lens using the supplied measurement data and defective-eyesight data, the volume being defined so as to achieve the desired correction of presbyopia or defective eyesight when removed.

A planning system generates control data for a treatment device for eye surgery that creates at least two incision surfaces in the cornea using a laser apparatus. The planning system includes a computation device configured to specify the cornea incision surfaces based on data of a refractive correction. The cornea incision surfaces include an access incision and a cap incision, with the access incision having a smaller diameter than the cap incision. The computation device being configured to generate a control data record for the cornea incision surfaces for purposes of controlling the laser apparatus.

Planning system and procedure for eye surgery

A method for performing a corneal ablation procedure on an eye of a patient including determining a refractive correction for the eye and determining a first parameter corresponding to the refractive correction or a condition of the patient. An ablation profile is selected that includes a refractive correction component and a pre-compensating component that is selected based on the first parameter. The ablation profile is configured to promote a controlled induction of a higher order aberration, where the pre-compensating component limits the induction of the higher order aberration to be within a predefined range. The cornea is ablated using the selected ablation profile.

Method for increasing ocular depth of field

A method and a device for forming cut surfaces in a transparent material, particularly in the cornea, by producing optical breakthroughs in the material by application of laser radiation focused into the material. The focal point is adjusted in three dimensions to form the cut surface by the sequential arrangement of optical perforations. The focal point is guided in such a manner that cutting is divided into at least two steps, and in at least one of the steps, the formation of the cut is carried out with a path radius that decreases in size, and in one of the steps, the cut formation is carried out with a path radius that increases in size.

A method of performing refractive laser eye surgery on a human eye is provided wherein the ablation pattern is centered along the visual axis, rather than along the line of sight. First, a wavefront, either ocular, corneal or a combination thereof, is generated by a wavefront sensor centered along the line of sight. This measured wavefront is centered on and encompasses a patient's pupil. Then, an analysis pupil is determined which encompasses the measured pupil. The analysis pupil is centered along the visual axis at the point of intersection with the cornea. Consequently, the measured wavefront is reconstructed over the analysis pupil only using data taken over the area covered by the measured pupil. This reconstruction is done through a least squares fit of a series of slopes from the measured wavefront and/or through the transformation of aberration coefficients. Finally, an ablation pattern, or a lenticule generation pattern, to be performed by a refractive laser centered on the corneal intersect of the visual axis is produced in accordance with the reconstructed wavefront.

A method for controlling a device for the treatment or refractive correction of the human eye using an electronic data processing system provides a simple overview of the influence of all of the parameters. To this end, once the operating parameters have been determined, a graphical simulation of the operating procedure is carried out in the form of a graphical visualization.

An apparatus for ultrasound scanning of the eye is provided comprising a virtual center translocation mechanism that facilitates precise arcuate motion of an ultrasonic transducer to maintain focal distance from the eye and to maintain normality of the ultrasound beam with surfaces of the eye. The invention also provides a radius adjust mechanism for changing the radius of ultrasound scanning to facilitate positioning of the transducer focal point on selected surfaces of the eye. Centration optics are also provided, for aligning the ultrasound transducer with the Purkinje (or other optical or geometric) axis of a patient's eye.
