Femtosecond Laser Technology Now Provides “Blade-less Cataract Surgery”
We are very proud to introduce the new Bausch and Lomb Femtosecond Laser for cataract surgery to our practice. Femtosecond technology is the newest and most advanced technique for cataract surgery in the world today. This remarkable advance in engineering represents the culmination of over ten years of research and development and is designed to improve the precision of the cataract procedure.
The laser does not perform the entire procedure, but it performs certain key aspects of the procedure that benefit from the extraordinary level of precision, accuracy, and reproducibility that only the laser can provide. The Femtosecond laser allows the surgeon to perform the surgery without using a blade to cut the tissues, it helps to address the refractive state of the eye by gently improving the contour of the cornea, thereby helping to reduce astigmatism, and it creates a precise circular opening in the cataract that helps the surgeon remove all the cloudy cataract material.
A practical way of thinking of medical lasers is that they are devices for delivering minute pulses of light energy that interact with our bodies in a very precise way. Lasers are often described by how long each pulse of light actually lasts… in this case that’s a femtosecond. A femtosecond is a quadrillionth of a second. A quadrillionth of a second is one millionth of a billionth of a second. That’s a pretty short burst of energy, but to get a grasp of how tiny these pulses of energy actual are, it’s useful to make a comparison. One femtosecond is to one second as one second is to 31.7 million years!
The Femtosecond surgical laser delivers these tiny bursts of energy and couples this energy with a space-age imaging system that measures structures in the eye to a thousandth of a millimeter. This precise measurement and energy delivery allows Drs. Colvard and Kandavel to customize each procedure to the anatomy of each individual’s eye.
