摘要： The disclosure provides a system that may receive an identification of a first patient; may retrieve, based at least on the identification of the first patient, first eye identification information that includes a first plurality of iris structures associated with a first eye of the first patient; may determine a second plurality of iris structures of an eye of a current patient; may determine if the second plurality of iris structures match the first plurality of iris structures; if the second plurality of iris structures match the first plurality of iris structures, may provide an indication that the first eye has been correctly identified; and if the second plurality of iris structures do match the first plurality of iris structures, may provide an indication that the first eye has not been correctly identified.

摘要： An ophthalmic surgical system for treating an eye comprises a laser device and computer. The laser device directs laser pulses at a treatment frequency towards the eye according to a shot list, which comprises a sequence of laser shots and corresponding locations. The sequence of laser shots comprises substrings, where each substring indicates a local shot frequency at a location. The number of laser shots in a substring depends on the treatment frequency. The computer performs the following for the substrings: if there is a change in the treatment frequency, adjust the number of laser shots in a substring; check whether the substring indicates that a local shot frequency satisfies a maximum local frequency at the treatment frequency; and if the local shot frequency fails to satisfy the maximum local frequency, adjust the shot list such that the local shot frequency satisfies the maximum local frequency.

摘要： The present disclosure provides a system for automated fine adjustment of an ophthalmic surgery support in which an eye tracking system detects a detectable position of an eye. The direction and distance the support must be adjusted for the eye to be centered may be determined based on the detectable position. A control signal is generated and transmitted to a control device that adjusts the position of the support to center the eye. The disclosure further provides a method for automated fine adjustment of a support, which includes detecting a detectable position of an eye, determining whether the eye is centered in relation to the center of the detection field of an eye tracking system based on the detectable position, determining a direction and a distance the detectable position must be adjusted to be centered, and generating and transmitting a control signal to adjust the position of the support.

摘要： A patient interface for an ophthalmic laser system includes an interface portion and an attachment portion. The interface portion includes a transmissive portion and an interface wall. The transmissive portion allows a laser beam through to the cornea of an eye to perform an ophthalmic procedure. The interface wall is disposed outwardly from the transmissive portion. The attachment portion couples the interface portion to a region of the cornea to allow the laser beam through to the cornea to perform the ophthalmic procedure. The attachment portion also decreases the temperature of the region during the ophthalmic procedure.

摘要： In certain embodiments, an ophthalmic laser ablation system comprises a laser device, liquid remover, and computer. The laser device directs laser radiation towards an eye as a plurality of shots to ablate tissue of the eye according to a treatment pattern. The liquid remover removes liquid from a surface of the tissue of the eye. The computer: determines a moisture maintenance procedure; instructs the liquid remover to remove the liquid from the surface of the tissue at a location of the eye according to the moisture maintenance procedure; and instructs the laser device to ablate the tissue at the location of the eye according to the treatment pattern.

摘要： In certain embodiments, an ophthalmic surgical system for performing a surgical procedure on an eye comprises a laser device, a camera, and a computer. The laser device comprises a laser source and a scanner. The laser source generates a laser beam comprising pulses, and the scanner directs the pulses towards tissue of the eye according to a laser focal spot pattern. The camera captures surgical images of the eye. The computer instructs the laser device to direct the pulses towards the eye according to the laser focal spot pattern, accesses and monitor the surgical images of the eye, identifies an interfering object from the surgical images of the eye, and modifies the control of the pulses to compensate for the interfering object.

摘要： Laser pulse modulation for laser corneal treatments is used to control the thermal energy imparted to the cornea. The optical energy of the laser pulses may be modulated to reduce or increase the thermal energy, depending upon an expected thermal load or a measured temperature at each position location of the cornea subject to laser treatment. The laser pulse modulation may involve pulse frequency modulation, pulse amplitude modulation, and pulse duration modulation.
