Femto-LASIK: Background and details
Femto-LASIK ("femto" comes from physics and refers to the time unit called a femtosecond, which in turn designates the quadrillionth part of a second) is a follow-up product of LASIK. It has been approved since 2001 and is currently one of the most common and popular laser eye surgeries. Common refractive errors of the eye such as nearsightedness, farsightedness, and astigmatism can be successfully corrected with Femto-LASIK.
The top layer of the cornea (epithelium) is detached using the femtosecond laser. To put it simply, the laser makes a small incision, and the thin cover of the cornea ("flap") is folded to the side. The actual correction is then performed using the so-called excimer laser. This process only takes a few seconds. The "flap" then reattaches itself so that your vision improves significantly within a very short time after the surgery. The Femto-LASIK procedure is quick and painless. However, temporary side effects may occur after the surgery (e.g., a slightly blurred vision is quite normal; a possible feeling of dryness can be treated with eye drops you'll receive from us anyway). This is one of the reasons why it's very important to keep your follow-up appointment after laser eye surgery.
