Laser treatment is contraindicated when an appropriate procedure cannot
be performed safely. This could occur when tissue targets cannot be
visualized properly. Corneal opacities, cataract formation and vitreous
hemorrhage can all interfere with the physician’s view of target tissues,
possibly leading to inadvertent photocoagulation of tissues/structures
adjacent to the tissue/structure of interest. Treatment should be delayed
until the ocular media problem resolves or is treated. If it is not possible,
an alternative form of therapy should be considered.
Laser energy is most commonly delivered to the eye by means of a slit
lamp that has been specially adapted for use as a laser delivery system. In
this case, the delivery system includes a lens system that focuses the laser
energy and changes the size of the laser spot in the slit lamp observation
plane. It may include a mechanism that manipulates the position of the
laser beam without moving the slit lamp. The laser energy is delivered to
the slit lamp by means of a flexible fiber optic.
For most procedures, a contact lens is used to direct the laser energy to the
part of the eye being treated. The contact lens may have mirrors so that
laser energy can reach peripheral areas of the retina or the irido-corneal
angle (e.g., the trabecular meshwork). The contact lens is also instrumental
in order to inhibit eye movements and to prevent eyelid closure, so that
laser energy can be delivered effectively and safely.
In young children or in physically impaired, disabled or unconscious
patients, the delivery of laser energy through a slit may not be possible. In
these cases, examination is done in the supine position, using a laser
indirect ophthalmoscope (LIO).
