Femtosecond is a measurement. In fact, one femtosecond (FS) is equal to one billionth of one millionth of a second. When a high repetition laser rate is used, eye surgeons can create smoother corneal flaps during LASIK surgery, making femtosecond lasers the preferred choice of ophthalmologists in your area. These higher pulse lasers are one of the most exciting technologies made available to ophthalmologists in many years. Eye surgeons have only scratched the surface with the possible uses of femtosecond lasers.
Using the Femtosecond Laser
With this particular laser, ophthalmologists can precisely cut tissue with virtually no heat development. By emitting ultra-short laser pulses with a diameter of 0.001mm at one-billionth of a second (10-15 sec), the femtosecond laser produces laser pulses that create a small gas bubble that separates the tissue. Ophthalmologists use the femtosecond laser in three types of eye surgeries:
- Incisions in the interior of the cornea
- Flap preparation in LASIK surgeries
- Preparation of corneal tunnels for intra-corneal ring segment (ICRS) implantation
Advantages of the Femtosecond Laser
The femtosecond laser has many advantages over mechanical techniques, but most notably the laser does the following:
- Improves patient comfort
- Produces better visual outcomes
- Reduces certain LASIK risks of infection and healing problems
Choosing an Eye Surgeon that Uses the Femtosecond Laser
Using a metal blade for cutting the corneal flap during LASIK surgery versus using bladeless techniques gives ophthalmologists a way to offer a much safer and more predictable outcome for patients. However, not all eye surgeons use the femtosecond laser, due to cost. So if you want to have the best in eye care as you consider LASIK, please choose a LASIK surgeon in your area that offers the femtosecond laser technology.
