LASIK (Laser-Assisted In Situ Keratomileusis) is a common vision correction procedure that reshapes the cornea to improve eyesight. Many individuals considering LASIK wonder if they will be “knocked out” or asleep during the surgery. Patients undergoing LASIK are not put under general anesthesia. The procedure is typically performed while the patient remains awake, ensuring their cooperation.
Anesthesia During LASIK
For LASIK surgery, the primary method of pain management involves topical anesthetic eye drops. These numbing drops are applied directly to the eye, blocking nerve signals to prevent pain. This localized approach makes the procedure virtually painless, allowing the patient to remain conscious and responsive. No injections or needles are used to numb the eye during LASIK.
Reasons for Staying Awake
Patients remain awake during LASIK for several important reasons, primarily to ensure the precision and success of the procedure. LASIK is a quick surgery, often taking 10 to 15 minutes for both eyes, with the laser working for one to two minutes per eye. Patient cooperation is essential, as the surgeon needs the individual to focus on a target light or follow specific instructions.
Avoiding general anesthesia also significantly reduces associated risks, as local anesthesia is generally safer. General anesthesia carries inherent dangers, including suppression of breathing rate, heart rate, and the nervous system. The minimal discomfort associated with LASIK due to numbing drops makes the greater risks of general anesthesia unnecessary. Remaining awake also allows for a quicker recovery, as patients can typically go home shortly after the procedure.
Your Experience During LASIK
During the LASIK procedure, patients can expect specific sensations, though pain is generally not among them due to the numbing drops. Patients might experience pressure when a suction ring is applied to stabilize the eye for flap creation. This sensation is often described as uncomfortable rather than painful. A mild oral sedative, such as Valium, may be offered to help nervous patients relax.
The eyes are held open with an eyelid speculum, preventing blinking. While the eye is numb, the eyelids are not, which might feel strange. Patients may see bright lights, such as a green or red fixation light, and their vision might become blurry or dim. Sounds of the laser and other equipment may also be audible. Advanced eye-tracking technology continuously monitors minor eye movements, allowing the laser to adjust or pause if necessary, ensuring accuracy.
