Checking the Condition of the Fiber
The fiber ends should be inspected to insure that they are round, smooth, clean and slightly
recessed. If any chips, dust, corrosion, or obvious concentricity errors are apparent, replace the
fiber. Generally, the laser does not cause fiber wear, but at times the ends of the delivery fiber
can be chipped due to rough handling.
WARNING: Never look directly into the distal end of the fiber while the laser is on, even
when wearing protective eyewear; serious eye injury can occur.
1. Turn off laser if laser is on.
2. Disconnect the fiber by unscrewing the fiber from the handpiece and unscrewing the
SMA connector from the laser.
3. Using a 7-10X eye loupe, examine both fiber ends. The ends should be slightly recessed
(~0.5 mm), clear of debris and round and smooth. See examples below.
Protruding Fiber Good Fiber
4. If either fiber end is missing, protruding, dirty, blackened, chipped or rough in
appearance, do not use. Replace with a new fiber.
5. Hold one fiber end to a bright source, a ceiling light, sunny window, etc., and look at the
other end. The fiber end should be illuminated brightly as compared to when it is not
pointed at a light source.
