What Happens During LASIK Surgery? Step-by-Step
Preparing for Your LASIK Procedure on Surgery Day
When you arrive on the day of your LASIK surgery, our team will greet you and review your information to confirm everything is ready. We will ask you to confirm your identity and the procedure details to ensure your safety. You will receive final instructions and have a chance to ask any last questions before we begin.
Our staff will guide you to a comfortable waiting area where you can relax before your procedure. We may ask you to wash your face and remove any makeup, contact lenses, or accessories that could interfere with the surgery.
Before the procedure starts, we will place numbing eye drops in both of your eyes to prevent any pain during surgery. These drops work quickly and typically take full effect within a few minutes. You will not feel discomfort during the laser treatment, though you may sense some pressure.
- The numbing drops may cause a slight tingling sensation at first
- Your eyes may start to feel heavy or less sensitive to touch
- We will verify that your eyes are properly numbed before proceeding
- Additional drops may be given to keep your eyes moist during the procedure
Our team will help you lie down on a cushioned procedure bed that reclines back comfortably. We will position your head under the laser machine and make sure you are relaxed and stable. A small device will gently hold your eyelids open so you do not need to worry about blinking during the treatment.
We will ask you to look at a blinking light above you, which helps us keep your eye in the correct position. The room lights will be dimmed, and you will see the fixation light clearly throughout the procedure.
The LASIK Procedure: Step-by-Step Breakdown
The first step in LASIK surgery involves creating a thin flap on the surface of your cornea. Our eye doctor uses a precise femtosecond laser to create this flap, which is safer and more accurate than older blade methods. You will feel gentle pressure on your eye during this part, but no pain.
The femtosecond laser creates thousands of tiny bubbles to separate the corneal layers, forming a flap in just seconds. This advanced technology allows us to customize the flap thickness and shape for your specific eye anatomy.
Once the corneal flap is created, our eye doctor gently lifts it back like turning a page in a book. This exposes the deeper corneal tissue underneath, called the stroma, where we will reshape your cornea. The flap remains attached at one edge, which helps it settle back into place later.
- The flap is extremely thin, usually about the thickness of a contact lens
- You may notice your vision blur slightly when the flap is lifted
- This step takes only a few seconds to complete
The excimer laser is the tool that actually corrects your vision by removing microscopic amounts of corneal tissue. This laser is programmed with your exact prescription and eye measurements taken during your pre-surgery evaluation. Each pulse of the laser removes a tiny layer of tissue, reshaping your cornea to correct nearsightedness, farsightedness, or astigmatism.
You will hear a clicking sound and may notice a distinct smell during this step. The smell comes from the laser interacting with corneal tissue and is completely normal. The laser tracks your eye movements automatically to ensure precise treatment even if you move slightly.
After the laser has finished reshaping your cornea, our eye doctor carefully repositions the corneal flap back to its original location. The flap naturally adheres to the underlying tissue without the need for stitches. We use a special instrument to smooth the flap and ensure it is perfectly aligned.
The flap begins to bond to the eye almost immediately, though complete healing takes a few days. We will rinse the area with a sterile solution to remove any debris and check that the flap is properly positioned before moving to the next eye.
Before completing the procedure, we perform several final safety checks to ensure everything went smoothly. Our eye doctor examines the corneal flap position under a microscope and verifies that no debris or wrinkles are present. We also check that your eye looks healthy and ready for healing.
- We may place antibiotic and anti-inflammatory drops in your eye
- The entire process is then repeated on your second eye
- Each eye typically takes about ten minutes or less to treat
- Both eyes are usually done in the same appointment
What to Expect During the Procedure
During LASIK surgery, you will not feel pain because of the numbing drops we use. However, you may experience a sensation of pressure when the device holds your eyelids open or when the laser creates the corneal flap. This pressure is mild and temporary, lasting only a few seconds at a time.
- You may hear clicking or buzzing sounds from the laser machines
- A faint odor similar to burning hair may occur when the excimer laser works
- You might feel coolness from the sterile solution we use to rinse your eye
- Some patients notice their vision dimming briefly during flap creation
Modern LASIK technology includes advanced eye-tracking systems that monitor your eye position thousands of times per second. If your eye moves beyond a safe range, the laser automatically pauses and waits for your eye to return to the correct position. This ensures the treatment is delivered exactly where intended.
The small device that holds your eyelids open prevents blinking, so you do not need to worry about keeping your eye open yourself. We also ask you to focus on the fixation light, which helps minimize natural eye movements during the brief treatment time.
The actual laser treatment for each eye typically takes less than a minute, though the entire procedure from positioning to completion lasts about ten minutes per eye. If you are having both eyes treated in one session, the total time in the procedure room is usually around 20 to 30 minutes. Most of this time involves preparation and safety checks rather than active laser treatment.
The speed of the procedure surprises many patients who expect it to take much longer. Despite the quick treatment time, we never rush and take all necessary time to ensure your safety and optimal results.
Immediately After Your LASIK Surgery
Right after LASIK surgery, your vision will likely be blurry and hazy, similar to looking through foggy glass. This is completely normal and expected as your eyes begin the healing process. Some patients can see well enough to walk around safely, but details will appear fuzzy and lights may have halos around them.
Your vision will fluctuate over the first few hours and days as your cornea heals and stabilizes. Many patients notice significant improvement within the first 24 hours, though it may take several days to weeks for your vision to fully settle.
Before you leave the surgery center, we will provide detailed instructions for caring for your eyes during recovery. We may recommend that you go home and rest with your eyes closed for several hours to promote healing. It is important to avoid rubbing your eyes, which could displace the corneal flap.
- Use all prescribed eye drops exactly as directed
- Wear the protective eye shields we provide, especially when sleeping
- Avoid getting water, soap, or makeup in your eyes for the first week
- Keep all scheduled follow-up appointments so we can monitor your healing
We will give you clear protective eye shields to wear over your eyes, especially while you sleep. These shields prevent you from accidentally rubbing or pressing on your eyes during the night when the corneal flap is most vulnerable. You should wear these shields for at least the first few nights or as long as we recommend.
You will receive antibiotic eye drops to prevent infection and anti-inflammatory drops to reduce swelling and discomfort. We may also provide lubricating drops to keep your eyes moist, as dryness is common after LASIK. Start using these drops according to our instructions as soon as you get home.
Recovery and Aftercare in the First Days and Weeks
During the first few hours after LASIK, your eyes may feel scratchy, irritated, or sensitive to light. These sensations typically improve as the day goes on. We recommend resting with your eyes closed for several hours after returning home to give your corneas time to begin healing.
- Hours 0 to 4: Rest with eyes closed, use drops as directed, expect blurry vision and discomfort
- Hours 4 to 8: Discomfort usually decreases, vision may start to clear slightly
- Hours 8 to 12: Continue resting and using drops, avoid screens and bright lights
- Hours 12 to 24: Vision often improves noticeably, though still fluctuating
Your first follow-up appointment is usually scheduled for the day after your LASIK surgery. During this visit, our eye doctor will examine your eyes to check that the corneal flap is healing properly and that no complications have developed. We will also measure your vision to see how much improvement has occurred.
Additional follow-up appointments are typically scheduled at one week, one month, three months, and six months after surgery. These visits allow us to monitor your healing progress and address any concerns. Some patients may need more frequent visits if they experience slower healing or other issues.
Protecting your eyes during the healing period is crucial for achieving the best results and avoiding complications. Always wear your protective eye shields when sleeping for at least the first week. Avoid swimming pools, hot tubs, and natural bodies of water for at least two weeks to prevent infection.
Keep soap, shampoo, and other potential irritants away from your eyes when washing your face or hair. Wear sunglasses when outdoors to protect your eyes from bright sunlight and reduce glare. Avoid dusty or dirty environments that could introduce particles into your healing eyes.
For the first few days after LASIK, avoid activities that could strain your eyes or risk injury. Do not rub your eyes under any circumstances, as this could dislodge the corneal flap. Limit screen time during the first 24 to 48 hours to reduce eye strain and allow proper healing.
- Exercise: Avoid strenuous workouts for one week; light walking is usually fine after a few days
- Sports: Wait at least two weeks before contact sports; protect eyes during activities
- Makeup: Avoid eye makeup for one week; face makeup may resume after a few days
- Driving: Do not drive until cleared by our eye doctor, usually after your first follow-up visit
- Work: Most patients return to desk work within one to two days
Signs of Complications and When to Seek Urgent Care
Normal healing after LASIK includes mild discomfort, light sensitivity, blurry vision, and dryness that gradually improve over the first few days. You may also experience halos around lights, glare, or fluctuating vision as your eyes heal. These symptoms are expected and should lessen with time.
Warning signs that are not normal include severe eye pain that does not improve with rest, sudden vision loss or significant worsening of vision, increasing redness or discharge, or the feeling that something is very wrong with your eye. Trust your instincts if something feels different from what we described during your pre-surgery education.
Contact our office immediately if you experience severe or worsening eye pain, especially if it is not relieved by over-the-counter pain medication. Call if you notice a sudden decrease in vision that does not improve with blinking or using lubricating drops. Increasing redness, thick discharge, or signs of infection such as pus require prompt attention.
- Any injury to your eye, such as being poked or hit, needs immediate evaluation
- Flashes of light or new floaters could indicate a serious problem
- Persistent severe headache along with vision changes warrants a call
- If you are unsure whether something is normal, it is always better to call and ask
Frequently Asked Questions
You should not feel pain during the procedure because we use numbing eye drops that completely anesthetize your eyes. While you may feel pressure or awareness of things happening, the numbing drops prevent actual pain sensations. Most patients describe the experience as uncomfortable at times but not painful.
A small, gentle device holds your eyelids open during LASIK, so you cannot blink even if you try. This may sound uncomfortable, but the numbing drops reduce any sensation from the eyelid holder. The device ensures your eye stays open and properly positioned without requiring any effort from you.
Our advanced laser systems include eye-tracking technology that follows your eye movements in real time. If your eye moves too much, the laser automatically stops and waits for your eye to return to the correct position before continuing. This safety feature ensures accurate treatment even if you cannot keep your eye perfectly still.
The excimer laser that reshapes your cornea typically runs for only 20 to 60 seconds per eye, depending on your prescription. Higher prescriptions may require slightly more laser time. This is the shortest part of the procedure, even though it is the most important step for correcting your vision.
No, you cannot drive yourself home after LASIK surgery because your vision will be too blurry and your eyes too sensitive. You must arrange for someone to drive you to and from the surgery center. Most patients are cleared to drive again after their first follow-up appointment the next day, once we confirm their vision has improved sufficiently.
