A device for the drying of tooth or bone surfaces includes a radiation source for irradiating the tooth or bone surface to be dried, a temperature sensor and/or a humidity sensor.

A method of corneal implantation with cross-linking is disclosed herein. In one or more embodiments, the method includes the steps of: (i) prior to implantation, treating an implant formed from donor corneal tissue or a tissue culture grown corneal stroma with a solution of sodium dodecyl sulfate (SDS), Triton X-100, benzalkonium chloride (BAK), Igepal, genipin, 100% glycerol, or alcohol for making the implant acellular, and for killing any bacteria, viruses, or parasites prior to implantation; (ii) implanting the implant into a recipient cornea; (iii) applying laser energy to the implant so as to modify the refractive power of the implant while being monitored using a Shack-Hartmann wavefront system so as to achieve a desired refractive power for the implant; and (iv) applying a cross-linking solution and irradiating the implant to cross-link the implant to prevent an immune response to the implant and/or rejection of the implant by a patient.

Disclosed are methods and medical device systems for automated delivery of therapies for pain and determination of need for and safety of treatment. In one embodiment, such a medical device system may comprise a sensor configured to sense at least one body signal from a patient; and a medical device configured to receive a first sensed body signal from the sensor; determine a patient pain index based at least in part on said first sensed body signal; determine whether said patient pain index is above at least a first pain index threshold; determine a safety index based at least in part on a second sensed body signal; select a pain treatment regimen based on at least one of said safety index and or a determination that said pain index is above said first pain index threshold; and deliver said pain treatment regimen.

In one aspect, embodiments relate to a system for preventative dental laser treatment that ensures even irradiation of a laser beam. The system includes, a laser arrangement configured to generate the laser beam. The laser beam has one or more of a super-Gaussian energy profile and a transverse ring mode. The system also includes a focus optic. The focus optic is configured to converge the laser beam with a numerical aperture of 0.1 or less to a focal region. The system also includes a hand piece configured to direct the laser beam at a surface of a dental hard tissue. The system additionally includes a controller. The controller is configured to control one or more parameters of the laser source, such that a portion of the surface of the dental hard tissue is heated to a temperature in a range between 400° Celsius and 1300° Celsius.

A feedback energy-release system and operation method thereof are provided, adapted to provide an energy parameter to an energy-release apparatus for performing a plurality of energy-release operations on a target skin. A feature capturing device captures tissue feature data of the target skin, wherein the tissue feature data captured before and after each energy-release operation are a first and a second tissue feature data, respectively. A control device compares the second tissue feature data with a plurality of reference tissue feature data to obtain at least one suggested energy parameter, determines grades of the tissue feature data of the current energy-release operation and records a grade distribution of the tissue feature data. The control device generates the energy parameter of the next energy-release operation according to a difference between the first and second tissue feature data, the at least one suggested energy parameter and the grade distribution.

Near-infrared/Mid-infrared lasers are used to de-claudicate glaucomatous tissue, translocate extra-ocular muscles, thermally pulsate palpebrae, and penileate/vasodilate superficial/epi-scleral membranes for dmg delivery. Diffractive optic element-mediated laser patterns may irradiate eye tissues under pulsed or continuous wave regimes with programmable durations and sequences for efficient treatments while minimizing adverse effects.

The presently disclosed subject matter provides techniques for inducing collagen cross-linking in human tissue, such as cartilage, by inducing ionization of the water contained in the tissue to produce free radicals that induce chemical cross-linking in the human tissue. In an embodiment, a femtosecond laser operates at sufficiently low laser pulse energy to avoid optical breakdown of the tissue being treated. In an embodiment, the femtosecond laser operates in the infrared frequency range.
