Are You Awake During LASIK?
The short answer is: yes, you are awake during LASIK surgery, but you'll be comfortably numb and won't feel any pain. This is a key difference between LASIK and other forms of refractive surgery. While you're awake, you'll be able to communicate with your surgeon throughout the procedure. Let's explore this in more detail.
What Happens During a LASIK Procedure?
LASIK (Laser-Assisted In Situ Keratomileusis) is a refractive surgery designed to correct vision problems like nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. The procedure involves creating a thin flap on the cornea (the clear front part of your eye) using a laser or a microkeratome (a blade). This flap is then lifted, and an excimer laser precisely reshapes the underlying corneal tissue to correct your refractive error. Finally, the flap is repositioned and allowed to heal naturally.
The entire process is remarkably quick, usually taking only about 15-20 minutes per eye. However, the pre-operative preparation and post-operative care extend beyond that timeframe.
Why Are You Awake During LASIK?
Keeping patients awake during LASIK offers several advantages:
-
Patient Cooperation: The surgeon needs the patient to remain still and focused on a target light during the procedure. This is far easier to achieve when the patient is awake and can understand instructions. Anesthesia isn't necessary to prevent pain, but topical anesthetic drops ensure comfort.
-
Real-time Monitoring: Keeping you awake allows the surgeon to monitor your response and comfort level throughout the procedure. Any discomfort or unexpected reaction can be addressed immediately.
-
Improved Accuracy: The patient's cooperation in maintaining eye position is crucial for the precision needed to achieve optimal results.
What Anesthesia is Used During LASIK?
While you're awake, you'll receive numbing eye drops to ensure complete comfort and eliminate any sensation of pain. These drops work quickly and effectively. In some cases, a mild sedative may be offered to help relax anxious patients, but general anesthesia is not typically used for LASIK.
What Will I Feel During LASIK?
You'll likely feel some pressure on your eye during the procedure, but no pain. Many patients describe a slight sensation of pulling or tugging. You might also experience some bright light, but your vision will be blurry. It’s vital to follow your surgeon's instructions and remain as still as possible throughout the procedure.
What Happens After LASIK?
After the procedure, you'll need someone to drive you home. Your vision might be blurry initially, but it should improve gradually within a few hours. Your surgeon will provide detailed post-operative care instructions, including eye drops and follow-up appointments. Complete healing can take several weeks.
Are there alternatives to LASIK?
Yes, there are other refractive surgical procedures available, such as PRK (Photorefractive Keratectomy), which doesn't involve creating a corneal flap. The choice of procedure depends on individual factors and should be discussed with your ophthalmologist.
This information is for general knowledge only and should not be considered medical advice. Always consult with a qualified ophthalmologist to discuss the suitability of LASIK or any other refractive surgery for your specific needs.
