LASIK surgery, or Laser-Assisted In Situ Keratomileusis, is a popular procedure designed to treat refractive vision problems such as myopia, hyperopia, and astigmatism. Understanding what to expect during and after the surgery can help alleviate concerns and prepare you for a smoother recovery. Below is a breakdown of the LASIK experience from the surgery itself to the post-operative care.

What to Expect During LASIK Surgery

LASIK surgery typically lasts about 15 to 30 minutes per eye. Here’s a step-by-step overview of the procedure:

1. Preparation: Before the surgery, your eye doctor will perform a thorough examination of your eyes, including measuring the thickness of your cornea and mapping its surface. This information is crucial for customizing the laser treatment.
2. Anesthesia: To ensure your comfort, numbing eye drops will be applied to your eyes. You may also be given a sedative to help you relax.
3. Creating the Flap: Once your eyes are numb, the surgeon will create a thin flap in the cornea using a microkeratome or a femtosecond laser. This flap is lifted to expose the underlying corneal tissue.
4. Laser Treatment: The excimer laser will reshape the cornea based on the predetermined measurements. This step typically takes just a few minutes and is painless.
5. Flap Replacement: After the laser treatment, the corneal flap is carefully laid back into place without the need for stitches.

Many patients report a sensation of pressure during the procedure but no significant pain. You may be asked to focus on a light during the laser application to help you stay still.

What to Expect Immediately After LASIK Surgery

After the surgery, you will be taken to a recovery area where you will rest for approximately 30 minutes. Here’s what to expect:

• You may experience mild discomfort, such as a gritty sensation in your eyes or slight tearing.
• Vision may be blurry immediately after the procedure, but many patients notice an improvement within a few hours.
• Your doctor will provide you with protective eyewear to prevent you from accidentally rubbing your eyes.
• Some patients report seeing halos or glare around lights, especially at night.

Post-Operative Care

Adhering to post-operative care instructions is crucial for optimal healing and results. Here’s what to follow after your LASIK surgery:

• Rest and Recovery: Schedule a friend or family member to drive you home post-surgery. Rest is essential, especially for the first 24 hours.
• Follow-Up Appointments: Attend all scheduled follow-up visits with your eye doctor to monitor your recovery process.
• Avoid Rubbing Your Eyes: This is vital in the first few weeks to ensure proper healing of the corneal flap.
• Use Prescribed Eye Drops: Your doctor will usually prescribe lubricating and antibiotic eye drops to prevent dryness and infection. Use them as directed.
• Limit Eye Strain: Avoid activities like reading, watching TV, or using digital devices for the first few days until your vision stabilizes.
• Protect Your Eyes: Wear sunglasses when outdoors to protect your eyes from UV rays, and avoid swimming or hot tubs for at least a month.

Long-Term Expectations

Most patients achieve vision between 20/20 and 20/40 after LASIK, but some might require additional enhancements in the future or may experience vision fluctuations as they age. Regular eye exams are essential for maintaining and monitoring eye health.

In conclusion, knowing what to expect during and after LASIK surgery can help you prepare mentally and physically, leading to a more successful experience. If you have additional questions or concerns, consulting with your eye care professional is always a good idea.
