A device for protecting tissue when treating an eye using a laser beam generated by a laser system and deflected by a scanner system comprises an eye model, a control data module and a processor. The eye model comprises eye data which define dimensions and locations of eye structures. The control data module is configured to register control data which define beam parameters of the laser beam and a scanning pattern for the laser beam. The processor is configured to simulate by computation a light spot moving on or in an eye structure on the basis of the eye data and the control data, to add up, for a plurality of measurement points of the eye structure and continuously, a beam dose emitted at the relevant measurement point by the moving light spot and to generate an emergency signal if a dose limit D.sub.max is exceeded at one of the measurement points.

A removable tip for a light energy handpiece comprises a hollow conduit configured to surround a light guide in the handpiece; a support extension having a length longer than a length of the hollow conduit; and a shielding extension coupled to the support extension at an angle less than 180 degrees and located in front of the hollow conduit. The shielding extension is configured to be inserted behind an eyelid and extend to the fornix, the shielding extension comprised of a thermally insulative material.

A shield for protecting the eye of a patient who is undergoing treatment of a facial area, such as the nose-bridge, forehead, temple, or an area immediately surrounding the eye. The shield has an outer shell of a formed semi-flexible or rigid metal foil that extends all the way to the edge of the shield, including an adhesive area of the shield that holds the shield around the eye of the patient. The foil layer is combined with one or more layers of polyester to avoid reflection of the light energy on the user or one or more layers of foam to provide for heat insulation, adhesion and patient comfort. The shield is formed at the contact portion to fit over the orbital area of the patient's eye.

Phototherapy systems comprising a therapeutic lamp platform for radiant lamps such as LEDs disposed in a holdable spot applicator assembly, the holdable spot applicator assembly including a reflective surface facing towards a patient and a plurality of LEDs for communicating lamp radiation from the lamps to a user. The lamps and associated circuitry are housed within a holdable elongated structure.

An eye safety system, based on retro-reflection from the eye, to shut off a laser source in a short time to avoid approaching the hazard level of the eye. In the event of an accidental direction of laser light toward a nearby eye, the system rapidly collects and detects laser light that retroflects from the retina of the eye. Upon detecting the retroflected light, a comparator/processor assembly signals to switch off the laser source to terminate the hazard to the eye.

An ocular protection device and treatment methods are disclosed. The device has a corneal shield with an attached handle. The handle may be used to move the corneal shield to better protect the eye from various treatment modalities. The handle may also be used to place tension on the eyelid to counteract the forces imposed by a treatment handpiece. A procedure for treating the eye is disclosed where multiple passes with a treatment handpiece cause a gradual increase in the temperature of an eyelid up to a treatment temperature. Once the treatment temperature has been met, occlusions in the Meibomian glands of the eyelid may be expressed. The procedure may be repeated recursively until a desired level of expression has been achieved.

An ophthalmic laser system for generating a first beam at a first wavelength on a first beam path and a second beam at a second wavelength on a second beam path, and directing optics to selectively direct the first wavelength or the second wavelength to a treatment beam path. The ophthalmic laser system incorporates a reflex coaxial illuminator comprising a reflex mirror movable on an axis from a position out of the treatment beam path to a position in the treatment beam path to direct illumination into an illumination path coaxial with the treatment beam path and a safety interlock only allowing operation of the ophthalmic laser system on the first beam path if the reflex coaxial illuminator is in a first position and allowing operation of the ophthalmic laser system on either the first beam path or the second beam path if the reflex coaxial illuminator is not in the first position.

A pivotable corner element for a radiation protection wall comprises at least one hinge defining a pivot axis and two side elements connected via the at least one hinge, wherein the side elements can be pivoted relative to one another around the pivot axis. Upon pivoting of the side elements, an intermediate space between the side elements results depending on a respective pivot position. The corner element has at least one blind arranged in the intermediate space, wherein the at least one blind is displaceable relative to the side elements in a way that the at least one blind at least partially covers the intermediate space independently from the respective pivot position.

Phototherapy systems comprising a therapeutic lamp platform for radiant lamps such as LEDs disposed in a holdable spot applicator assembly, the holdable spot applicator assembly including a reflective surface facing towards a patient and a plurality of LEDs for communicating lamp radiation from the lamps to a user. The lamps and associated circuitry are housed within a holdable elongated structure.

Described herein are loupes shields. The shields can be easily attached to the loupes. The loupes shield is composed of a single filter that blocks harmful light. Additionally, the loupes shield includes a connector that permits the loupes shield to be attached to the loupes lens or housing that holds the loupes lens. The loupes shields described are useful in applications where it is desirable to protect the user from being exposed to damaging light. The loupes shields are useful in dental applications such as, for example, dental restorations, where light cure is required to cure the resin applied to a tooth during a dental restoration.
