Laser energy is delivered to opaque structures within the eye through a slit lamp that has
been specially adapted for use as a laser delivery system.
The delivery system includes a lens system to focus the laser energy and vary the size of
the laser spot in the plane of observation of the slit lamp. It includes a
mechanism to
manipulate the position of the laser beam without moving the slit lamp. Laser energy is
delivered to the slit lamp through a flexible fiber optic.
For most procedures, a laser contact lens is used to direct laser energy to the part of the
eye being treated. The contact lens may have mirrors so that laser energy can be
delivered to areas of the retina behind the iris or into the angle so that the trabecular
meshwork can be treated. The contact lens also helps to hold the eye open and still so
that laser energy can be delivered effectively.
Systems may be used for procedures performed in a
hospital or in a physician’s office, for
in-patient or out-patient procedures. The use of the laser system is not a contributing
factor in deciding whether a procedure is done on an in- or out-patient basis.
