A system, technique and material composition for use in correction of eye condition are disclosed. The system comprising a processing utility and an etching utility. The processing utility comprises: correction pattern module configured for providing a selected two-dimensional pattern in according with input data indicative of vision impermanent of a user, and for generating operational instructions for forming said selected two-dimensional pattern on the surface of the cornea by said etching utility. The etching utility is configured to etching the selected patter on surface of the cornea of a user. The material composition comprises aqueous solution comprising a plurality of nanoparticles, said nanoparticles comprising maghemite nanoparticles wrapped by biocompatible protein chains. The material composition may be used as eye drops thereby allowing the nanoparticles to occupy etched region on the cornea, thereby maintaining correction of eye condition.

Intraocular pressure in an eye is reduced by delivering a high resolution optical coherence tomography (OCT) beam and a high resolution laser beam through the cornea, and the anterior chamber into the irido-corneal angle along an angled beam path. The OCT beam provides OCT imaging for surgery planning and monitoring, while the laser beam is configured to modify tissue or affect ocular fluid by photo-disruptive interaction. In one implementation, a volume of ocular tissue within an outflow pathway in the irido-corneal angle is modified to create a channel opening in one or more layers of the trabecular meshwork. In another implementation, a volume of fluid in the Schlemm's canal is affected by the laser to bring about a pneumatic expansion of the canal. In either implementation, resistance to aqueous flow through the eye is reduced.

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.

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.

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 photo detector is selectively coupled to a first integrator or a second integrator with switching circuitry when the laser pulses. An integration time of the signal from the photo detector can be substantially greater than an amount of time between successive laser beam pulses in order to provide an accurate measurement of each laser beam pulse of a high repetition rate pulsed laser. The laser may comprise a clock coupled to an optical switch of the laser system, and control circuitry can control switching and coupling of the detector to the first integrator or the second integrator in response to the clock signal. The first integrator and the second integrator can be selectively coupled to an output such that the first integrator or the second integrator is coupled to the output of the energy detection circuitry when the other integrator is coupled to the detector.

An imaging-based laser system can include a laser-beam system, configured to generate and scan a beam of laser pulses with an adjustable laser-power parameter to points of a scan-pattern in an eye, and an imaging-based laser-controller, configured to image a layer in the eye, to control the scanning of the beam of laser pulses to the points of the scan-pattern, and to control a laser-power parameter of the laser pulses according to the distance of the points of the scan-pattern from the imaged layer.

An imaging system includes an eye interface device, a scanning assembly, a beam source, a free-floating mechanism, and a detection assembly. The eye interface device interfaces with an eye. The scanning assembly supports the eye interface device and scans a focal point of an electromagnetic radiation beam within the eye. The beam source generates the electromagnetic radiation beam. The free-floating mechanism supports the scanning assembly and accommodates movement of the eye and provides a variable optical path for the electronic radiation beam and a portion of the electronic radiation beam reflected from the focal point location. The variable optical path is disposed between the beam source and the scanner and has an optical path length that varies to accommodate movement of the eye. The detection assembly generates a signal indicative of intensity of a portion of the electromagnetic radiation beam reflected from the focal point location.

A laser system that includes a laser source emitting a laser beam along an axis and a keratometer. The keratometer includes a first set of individual light sources that are equally spaced from one another along a first ring and that direct a first light toward an eye and a second set of individual light sources that are equally spaced from another along a second ring and direct a second light toward the eye, wherein the first ring and said second ring are co-planar and concentric with one another about the axis. The laser system includes a telecentric lens that receives the first light and second light reflected off of the eye and a detector that receives light from the telecentric lens and forms an image. The laser system also includes a processor that receives signals from said detector representative of the image and determines an astigmatism axis of the eye based on the signals.

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.
