Section 4 PRINCIPLES OF OPERATION
4.1 General Description
The LightLas 532 Green Laser is an Ophthalmic Laser suitable for performing the
following clinical procedures:
Retinal Photocoagulation
Pan Retinal Photocoagulation
Endo photocoagulation
Macular Treatments
Laser Trabeculoplasty
The LightLas 532 Laser system has a wavelength of 532nm, which is in the visible
spectrum and is a green light. A red aiming beam is used to position the treatment
green light beam prior to delivery.
The word LASER is an acronym for “Light Amplification by Stimulated Emission of
Radiation”. The light from a laser has particular characteristics, which makes it a
valuable tool for medical applications.
The beam from a laser is collimated which means that the beam does not
diverge and can maintain a constant diameter over a long distance. This
means that the Laser beam can be focused to a very small spot with high
energy and power densities.
The beam is Monochromatic, which means that it is a single wavelength
beam and therefore the effects of the beam on tissue are very predictable
and reproducible.
The light waves are coherent which means they are in phase with each
other and do not interfere and generate losses in energy.
The LightLas 532 system consists of a laser console where the green laser is housed
along with the electronic control system and power supplies and accompanies along
with various Laser Delivery Units (LDU’s). These LDU’s include:
Slitlamp Integrated into CSO model SL980
Slitlamp Attachment for CSO model SL990 and other Haag Streit clones.
Slitlamp Attachment for Zeiss model SL30 Slitlamp
Laser Indirect Ophthalmoscope (LIO) using a Keeler II
Endo photocoagulation hand pieces (Endoprobes)
When using these LDU’s a microscope Doctor Safety Filter (DSF) is required to
protect the doctor from unexpected reflections causing eye injury during the
treatments. The DSF is mounted in the beam path of the microscope.
