What Happens Before, During, and After a LASIK Eye Surgery Procedure?
Summary:
Since its FDA approval in the early 1990s, LASIK has become the most commonly performed eye surgery in the United States. This procedure, known as Laser-Assisted In-Situ Keratomileusis (LASIK), reshapes the cornea with a laser to correct vision, reducing the need for glasses or contact lenses. LASIK effectively addresses refractive errors, including myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.

What to Expect Before, During, and After LASIK Eye Surgery
Since its FDA approval in the early 1990s, LASIK has become a popular option for those seeking to correct their vision. The procedure, Laser-Assisted In-Situ Keratomileusis (LASIK), uses a laser to reshape the cornea, potentially eliminating the need for glasses or contact lenses. It addresses various refractive errors, such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.
Before the Procedure
Before undergoing LASIK, patients receive detailed instructions to ensure the success of the surgery. Those who wear contact lenses are typically advised to stop using them 2-4 weeks prior, allowing their eyes to return to their natural shape. Additionally, certain foods, vitamins, beauty products, and medications may need to be avoided. Following these instructions is crucial to avoid complications or the need to redo the surgery.
During the Procedure
Patients remain awake during the surgery, though a mild sedative and numbing eye drops are administered to keep them comfortable. A lid speculum is used to hold the eyelids open, preventing blinking.
A small ring then applies strong suction to the cornea, ensuring the eye stays still. Although this can be slightly uncomfortable, it's essential for the process. Next, a flap is created in the cornea using either a microkeratome (a fine knife) or a laser, and the flap is lifted to expose the inner layers of the cornea.
The patient is instructed to focus on a fixed light. The programmed excimer laser removes precise amounts of tissue to reshape the cornea. Patients may hear a ticking or zapping sound and notice a slight odor during this process. Once completed, the surgeon places the flap back in its original position and smoothens it to avoid wrinkles.
After the Procedure
Following LASIK, the eye is sensitive and needs protection. An eye shield is provided to wear during sleep, preventing accidental rubbing or pressure. Antibiotic ointment and eye drops are prescribed to prevent infection and alleviate dryness.
A follow-up appointment is scheduled within 24-48 hours of the surgery to monitor healing and check for complications. Regular check-ups will occur in the following weeks and months to ensure successful recovery and optimal results.
Important Considerations
It's important to understand that LASIK is not risk-free, and not everyone is a suitable candidate. If you're considering LASIK, consult with your ophthalmologist to discuss your options and determine if it’s the right choice for you.
