A laser eye surgery system produces a treatment beam that includes a plurality of laser pulses. An optical coherence tomography (OCT) subsystem produces a source beam used to locate one or more structures of an eye. The OCT subsystem is used to sense the distance between a camera objective on the underside of the laser eye surgery system and the patient's eye. Control electronics compare the sensed distance with a pre-determined target distance, and reposition a movable patient support toward or away the camera objective until the sensed distance is at the pre-determined target distance. A subsequent measurement dependent upon the spacing between the camera objective and the patient's eye is performed, such as determining the astigmatic axis by observing the reflection of a plurality of point source LEDs arranged in concentric rings off the eye.

Disclosed are a method and a device for controlling an eye surgery system, wherein a light pattern is generated on an eye by an illumination device and is captured by a camera unit while the patient is in the position in which he or she will undergo the surgery. At least one property of the eye characterizing the current orientation of the eye during the surgery is determined from the light pattern by a computing unit.

Systems, methods, and computer-readable media for integrating and optimizing a surgical suite. An ophthalmic suite can include a surgical console, a heads-up display communicatively coupled with a surgical camera for capturing a three-dimensional image of an eye, and a surgical suite optimization engine. The surgical suite optimization engine can performs a wide variety of actions in response to action codes received from the other components in the surgical suite. The surgical suite optimization engine can be integrated within another component of the surgical suite, can be a stand-alone module, and can be a cloud-based tool.

An example system for tracking motion of an eye during an eye treatment includes an image capture device configured to capture a plurality of images of an eye. The system includes controller(s) including processor(s) that receive the plurality of images from the image capture device. The processor(s) implement a plurality of trackers. Each tracker is configured to detect a respective feature in the plurality of images and provide, based on the respective feature, a respective set of data relating to motion of the eye. The respective features detected by the plurality of trackers are orthogonal relative to each other and the respective sets of data provided by the plurality of trackers are independent of each other. The processor(s) coalesce the sets of data from the plurality of trackers and determine an indicator of the motion of the eye based on the coalesced sets of data.

A method is disclosed for determining a position of a laser focus of a laser beam of an eye surgical laser of a treatment apparatus by means of a control device of the treatment apparatus, in which the laser beam of the treatment apparatus is emitted into or onto a human or animal eye and in which at least two Purkinje images of the laser beam on the eye are captured by means of an optical capturing device of the treatment apparatus, and in which the position of the laser focus in or on the eye is determined by means of the control device considering the captured Purkinje images and considering an opening angle of the laser beam. Further disclosed are a treatment apparatus, a computer program and a computer-readable medium for carrying out the afore-mentioned method.

Methods and systems wherein laser induced refractive index changes by focused femtosecond laser pulses in optical polymeric materials or ocular tissues is performed to address various types of vision correction.

Rather than rely solely upon pupillary occlusion or tracking of eye movement to protect the fundus from accidental exposure to electromagnetic radiation, the present invention also utilizes an electromagnetic radiation pathway with a profile such that the energy density at the iris is greater than the energy density at the posterior portion of the eye. This disparity in energy density allows for efficacy at the anterior iris treatment site, without injury to the fundus.

A system for processing a portion in a processing volume of a transparent material by application of focused radiation including a device for generating and an optical system for focusing radiation, with a device for changing the position of the focus of the radiation and a control device. The system includes a controller that controls the ophthalmologic therapy system. The controller is encoded with a scan pattern. The scan pattern includes adjacent strokes with each adjacent stroke having an angle of inclination (α) to the beam axis; and the angle of inclination (α) of the strokes to the beam axis is always larger than or equal to the focal angle (φ) of the focused radiation.

In certain embodiments, a system for tracking movement of an eye comprises a camera system, a computer system, and an output device. The camera system generates images of the eye. The computer system stores the images and at least one of the images as a reference image. The computer system also tracks movement of the eye within a tracking range by comparing a current image with the reference image, and by determining a movement of the eye from the comparison of the current image and the reference image. The tracking range has one or more alert points. The computer system also determines an orientation of the eye relative to at least one alert point of the tracking range. The output device outputs a range indicator that indicates the orientation of the eye relative to the at least one alert point of the tracking range.

A first image of the eye is generated when the cornea of the eye is exposed to a gas. The cornea is covered with an optic of a patient interface. A second image of the eye with the patient interface over the cornea is generated. In this second image, the patient interface distorts the second image of the eye. One or more of a position or an orientation of the eye is determined in response to the first image and the second image when the patient interface has been placed over the cornea.
