LASIK, or Laser-Assisted In Situ Keratomileusis, is a widely performed surgical procedure designed to correct common vision problems such as nearsightedness, farsightedness, and astigmatism. Many individuals considering LASIK often wonder if they will be asleep during the surgery.
Anesthesia During LASIK
Patients undergoing LASIK surgery remain awake and responsive during the procedure. Anesthesia primarily involves topical anesthetic eye drops applied directly to the eye. These drops effectively numb the eye, blocking nerve signals for a pain-free experience. The numbing effect typically lasts 30 to 40 minutes, sufficient for the surgery’s duration.
To enhance patient comfort and reduce anxiety, a mild oral sedative may be offered before the procedure. This medication induces a state of calm and drowsiness, but it does not cause full unconsciousness. Patients can still hear and follow instructions from the surgeon, which is important for the success of the procedure.
Reasons Against General Anesthesia
General anesthesia, which renders a patient completely unconscious, is not used for LASIK surgery. A primary reason is the necessity of patient cooperation during the procedure. Surgeons require patients to fixate on a target light and follow verbal instructions for precise laser application to the cornea. This level of interaction is not possible under general anesthesia.
General anesthesia also carries increased risks compared to topical anesthesia. These risks include respiratory complications, nausea, vomiting, confusion, agitation, and a longer recovery period. Since LASIK is a quick procedure, often lasting only a few minutes per eye, the risks of general anesthesia are disproportionately high and unnecessary. Local anesthesia with mild sedation is a safer approach for this minimally invasive surgery.
Patient Comfort During the Procedure
Several measures ensure patient comfort and manage anxiety throughout the awake LASIK procedure. Before laser treatment begins, an eyelid speculum is placed to hold the eyelids open and prevent blinking. This device, along with numbing eye drops, helps patients avoid involuntary movements and maintain a steady gaze.
The mild oral sedative helps patients feel relaxed. Throughout the surgery, the surgical team maintains clear communication, explaining each step and offering reassurance. The entire procedure is quick, taking only one to two minutes per eye for the laser application. This brief duration minimizes the time a patient might experience sensations, generally described as mild pressure rather than pain.
