Abstract
A mirror for an ophthalmic laser treatment device that is movable on an axis from a position in a treatment laser beam path to a position out of the treatment laser beam path. The mirror reflects light from a light source into the eye of a patient. The mirror is biased towards a position in the path and is moved out of the path by an actuator just long enough for the laser treatment to be applied and without noticeable interruption to viewing by a user.

A reflex coaxial illuminator for an ophthalmic laser device comprising a reflex mirror movable on an axis from a position in a treatment laser beam path to a position out of the treatment laser beam path.
An ophthalmic laser device incorporating a reflex coaxial illuminator, the reflex coaxial illuminator comprising:
- a mirror movable on an axis from a position in a treatment laser beam path to a position out of the treatment laser beam path;
- and
- an actuator that moves the mirror.
An ophthalmic treatment device comprising:
- one or more aiming lasers producing aiming laser beams that are directed into a treatment path to a target treatment area by at least a first mirror;
- a treatment laser producing a treatment laser beam that is directed into the treatment path by a second mirror;
- a viewing microscope that views the target treatment area along a viewing path coaxial with the treatment path;
- and
- a reflex mirror directing illumination from a source of illumination into an illumination path coaxial with the treatment path;
- wherein the reflex mirror is movable on an axis from a position in the treatment path to a position out of the treatment path.
A method of performing ophthalmic laser treatment including the steps of:
- illuminating a target treatment area with illumination directed coaxially along a treatment path by a reflex mirror;
- directing aiming laser beams along the treatment path to the target treatment area;
- viewing the target treatment area and adjusting the aiming laser beams to be aimed at a selected treatment zone;
- and
- activating a treatment laser to produce a treatment laser beam that is directed into the treatment zone;
- wherein the reflex mirror is moved out of the treatment path prior to treatment laser emission and then moves back into the treatment path after treatment laser emission ceases.
