Will Femtosecond Laser Technique Postpone the Need for Cataract Surgery?

August 12, 2010

In reviewing an article about proposed new uses for the femtosecond laser, I came across a term that I had not heard of before ā€“ laser photolysis. It turns out that laser photolysis with a femtosecond laser is being evaluated to photobleach human lenses and thus postpone the need for cataract surgery.

Dr. Line Kessel and her colleagues in Denmark have tested a technique of scanning the output of a femtosecond laser across human lenses and brought back transparency through photobleaching without damage to the lenses, thereby postponing the need for cataract surgery by from 3 to 7 years. This work was done on donated human lenses from the Cornea Bank NORI in Amsterdam but, if this process becomes feasible for living lenses, the consequences are enormous.

But, Iā€™m getting ahead of myself. First take a look at Dr.Joseph Colinā€™s writeup on new applications for femtosecond lasers that appeared in OSN Europe, and then read my treatise on Laser Photolysis.
