8 LASER CATARACT AND PI SURGERY

Precision and safety has increased with the advent of femtosecond
lasers for cataract, Prelex and Pi surgeries.
In a painless procedure lasting under two minutes the laser can
make openings in the eye. It can also make relaxing incisions to
correct astigmatism. The laser can now make a desired size opening
of the lens bag. It is exciting to know that the laser can even break
the lens into multiple pieces of desired shape and size. This make it
easier to remove the lens pieces with least amount of energy.
