What Happens Throughout Laser Eye Treatment?

What Happens Throughout Laser Eye Treatment?

Laser eye treatment is a quick and pain free process which is very effective for correcting vision

. One of the main concerns when it comes to refractive surgery is knowing what exactly happens throughout laser vision correction. Even anti-spectacle patients will be turned off with the idea of lasers burning the eyeballs!

For anyone who is curious, the biggest reservation is this - what precisely happens when laser eye treatment ultimately takes place?

Initially, local anaesthetic eye drops is placed on both eyes for a pain free operation. A mild stinging sensation that lasts give or take 10 seconds is usual as well as a slight uneasiness that is present throughout the treatment. It takes up to 30 minutes for the anaesthetic to take effect but lasts for the whole process, wearing off hours after the operation has taken place.

To mildly hold the lids aside to prevent blinking from impeding the actual lasering or ablation of the cornea, a clamp is used. As you cannot blink yourself, from this point onwards lubricants will be applied to your eye at regular intervals.

With lasik, the most general form of laser eye treatment, a flap is made on the top layer of the cornea, generally with an intralase laser. This flap is left attached to the front of the eye and flipped back to reveal the underlying cornea.

An excimer laser will then vaporize the stromal layer of the cornea to the curvature of choice. This part of the surgery takes less than 10 seconds throughout which you will be instructed to look at a blinking light. With advanced excimer lasers, eye tracking is incorporated into the system so the laser will not fire unless you are looking directly into the target, ensuring accuracy in this most integral part of laser eye treatment.

Afterwards, the ophthalmologist will carefully place the flap back over the eye, giving particular attention to centering and avoiding any dust which may be trapped underneath the flap. This operation requires no stitches at all.

The flap creation and the ablation with the excimer laser is performed one eye at a time.

20 minutes after the laser eye treatment, a quick follow-up analysis is done.

Placed over the eye is a plastic transparent shield, instantly performed after the procedure. This is necessary to dissuade rubbing of the eyes and foreign objects entering the eyes shortly after surgery. The shield is left on for the day and can be removed yourself the following day.

Lasik eye operation is a procedure where no pain is expected after the surgery. There are few cases, however, where some patients get a minor irritation which can be treated with pain tablets on an as-needed basis.

The entire process of laser eye surgery only takes up give or take 90 minutes of one's time. A small time frame for years of clear, spectacle free sight.
