LASIK (Laser-Assisted In Situ Keratomileusis) is a widely performed surgical procedure designed to correct vision problems such as nearsightedness, farsightedness, and astigmatism. Many individuals considering LASIK often wonder about the experience during the surgery, particularly concerning comfort and awareness. This article aims to clarify the role of anesthesia in LASIK and describe what patients can expect throughout the process.
Anesthesia During LASIK
Patients undergoing LASIK are not “put to sleep” with general anesthesia, which induces a state of unconsciousness. Instead, the procedure relies on topical anesthetic eye drops, such as proparacaine, to numb the eyes. These drops effectively block pain signals from the corneal nerve endings, making the surgery virtually painless.
This localized approach is preferred because patient cooperation is helpful. Being awake allows individuals to follow instructions from the surgeon, such as focusing on a target light, which is important for precise laser application. Topical anesthesia also leads to a quicker recovery and avoids the risks associated with general anesthesia, such as suppressed breathing and heart rate.
A mild oral sedative, such as diazepam (Valium), may be offered to help patients relax before the procedure. This helps alleviate anxiety without causing unconsciousness. Patients remain awake and responsive, able to communicate with the surgical team.
No injections or needles are used to administer the anesthetic during LASIK. The numbing eye drops are the sole method of anesthesia for the eye, contributing to patient comfort. The effects of these drops typically last for several hours, providing pain relief even after the surgery is complete.
What You Will Experience
Patients remain awake during LASIK and will experience various sensations, though typically no pain. Before the laser treatment begins, an instrument called a lid speculum is used to gently hold the eyelids open, which may feel slightly uncomfortable as the numbing drops do not affect the eyelids.
During the initial stage of creating a corneal flap, a soft suction ring is applied to the eye. This creates a feeling of pressure, which some describe as the most unusual or uncomfortable part of the procedure, and it can cause vision to dim briefly. This suction lasts only for a short duration, usually around 30 seconds.
When the laser reshapes the cornea, patients are asked to focus on a target light. This part of the procedure is painless, with many patients reporting no sensation during the actual laser application. The laser makes distinct sounds, audible during the several seconds it takes to reshape each eye.
The laser application for each eye is brief, typically lasting between 5 and 20 seconds. Some patients report a sensation like water running over their eyes, which is due to saline solution used by the surgeon to keep the eyes hydrated. After the procedure, it is common to experience mild irritation, a gritty feeling, or dryness, but significant pain is rare.
Addressing Pre-Surgery Nerves
Feeling anxious before eye surgery is a common reaction. Many people experience jitters before LASIK, a safe procedure with a high satisfaction rate, often above 96%.
One effective strategy to alleviate pre-surgery anxiety is to talk openly with your surgeon and the clinical staff. Asking questions about the procedure, understanding each step, and clarifying any concerns can help you feel more informed and in control.
A mild oral sedative may be offered to help calm nerves before the procedure. This helps foster a relaxed state while ensuring you remain awake and able to follow instructions. Additionally, practicing relaxation techniques such as deep breathing exercises, where you focus on rhythmic inhalation and exhalation, can help soothe the nervous system.
The short duration of the LASIK procedure itself, with the laser actively working for only seconds per eye, often surprises patients and helps to ease concerns. Focusing on the high success rates and the life-changing benefits of clear vision can also provide a positive outlook, helping to manage any remaining pre-surgery anxiety.
