What Happens in Laser Eye Surgery?

The journey for a LASIK patient is similar across all laser vision correction centers. Where the LASIK process differs most is the depth of the pre- and post-operative phases, which we’ll include in our description here:
During the pre-operative stage of your patient journey, we’ll:
Our aim during the first appointment is to measure and photograph your eyes to see if we can help you. We’ll perform a lot of tests and scans of your eyes so that we can get the most accurate and comprehensive picture of their condition.
You’ll also meet me, your surgeon. I will examine your eyes personally and confirm whether you are or are not suitable for a procedure.
If we can offer you a treatment, we’ll discuss the options and alternatives with you. If you agree with our recommendations, we’ll ask you to read a surgical information package and sign a consent form. You’ll be able to take these home to review at your convenience so you don’t feel rushed.
When you book your first appointment, we’ll give you some instructions on what to bring and how to prepare for your journey home. You can see a handy checklist that will help you prepare for this treatment as well.
On the day of the operation, you’ll come to the clinic half an hour before your scheduled appointment begins.
At the start, the nurse will go over the post-operative drops and sunglasses that you’ll need for a little while after the procedure. Then, I’ll examine your eyes, and we’ll then lead you to the operating room.
When you enter the operating room, we’ll ask you to lie down comfortably on the operating bed. I will likely be programming and calibrating the laser as you get settled. The nurse will give you a few simple instructions that I will repeat during the procedure.
I will clean your eyes and put a patch on the other so that you are not distracted, then we’ll get you situated under the microscope. I’ll place a lid holder to support your eyelids so that we can begin the operation.
The first step of the operation involves anesthetizing your eyes and creating a corneal flap. You’ll remember that the cornea is the front window of the eye that performs most of the focusing work.
Once your eye is numb, I’ll lay a suction ring on the surface of your eye. Then I’ll use a foot pedal to activate a precisely controlled suction system to adhere the ring to the eye. Next, the applanation cone lowers down to dock with the suction ring. A second automated suction system engages which secures the application cone within the suction ring while applanation occurs.
The femtosecond laser eye creates the microscopically thin flap within 6 seconds. We don’t use a blade; we use a laser to create the flap. All you’ll feel is some pressure that’s created by the mild suction.
You might, at this point, worry about blinking. Don’t, because the lid holder will prevent you from doing so. Your eyes won’t feel dry because the anesthetic will numb that feeling and we’ll be lubricating your eye throughout the procedure.
Once made, I’ll very gently lift the flap and turn it over on a hinge – a bit like opening a door. Don’t worry; you won’t feel a thing.
I’ll tell you to fixate your vision on a red light, and once we’re ready, I’ll start the laser. As the laser treats your eye, the nurse and I will be talking to you, telling you what to expect so that we don’t surprise you. It will be over before you know it.
You may worry that you won’t be able to keep your eyes fixated. Don’t worry; the laser has an eye tracker that will instantly shut it off if your eye position moves.
When the laser stops treating (usually between 10 to 30 seconds later), I’ll lightly clean and rinse the treated area and then replace the flap, ensuring I reposition it perfectly. I then remove the lid holder.
It’s all over in (often much) less than a minute. Then, we’ll repeat the process in your second eye, if that’s what we planned.
After the procedure, I’ll ask you to sit up. I’ll examine your eyes immediately afterward, and then escort you to the darkened recovery room where I’ll ask you to close your eyes and relax in a comfortable chair.
Fifteen to twenty minutes later, you’ll be free to go.
For the first day, I’ll encourage you to rest and sleep. You can typically drive and return to most jobs the next day.
I’ll want to see you the day after your procedure, three to four weeks after that, and then in three months.
At these visits, we’ll measure your visual acuity (how well you see) and ensure your eyes are recovering well from surgery.
You’ll have ample opportunity during these visits to ask me about what you’re experiencing.
Usually, patients see very well the very next day after surgery. Some patients may require a little longer, depending on the treatment they had. The key things to remember during this stage are:
And that’s it. You’ve had LASIK!
