1. Use of a coated fiber (should not use the stripper)

(Left) A unstripped laser fiber with blue fiber sheath

(Middle) A laser fiber without blue fiber sheath

(Right) Balltip laser fiber

2. Use of a balltip laser fiber

Insertion of a balltip laser fiber into a flexible URS is possible when the deflection angle is < about 200 degrees. Therefore, we should insert the laser fiber first and then perform the maximal deflection into 270 degrees.

3. Use of a laser fiber protector
