How does blended Laser Eye Surgery work?
If you’re anything like me, you won’t dive into a new therapy, course of medication, or treatment until you know everything there is to know about it.
It’s an admirable trait — albeit one that can become annoying when encountering conflicting information and reviews online, to later realise you’ve spent six hours non-stop staring at a screen.
Fortunately, your research session today won’t end with you as a whirring, hazy lump, lying eyes wide on the couch or in bed. Here we’re going to lay out in jargon-free terms just how blended Laser Eye Surgery — otherwise known as Laser Blended Vision — works. Simple as that. No complicated medical terminology, no sneaky sales tactics — just clear and valuable information you can use to further inform your understanding of this revolutionary treatment for presbyopia.

So let’s now take a look at the process, starting from the initial screening that every patient goes through prior to having Laser Eye Surgery, and ending with the post-surgery days of clear and frustration-free vision.
Turning back the clock with Laser Blended Vision
Laser Blended Vision is a type of refractive surgery that is specially designed for treating presbyopia and therefore alleviating the difficulties of viewing objects up close (things like newsprint, pill bottles, books, and small print). However, at the same time it corrects patients distance vision as well.
In the initial screening, patients undergo a variety of tests and measurements to ascertain whether they are suitable candidates for a full Laser Blended Vision treatment. Certain factors like having a thin cornea or a health condition such as diabetes may disqualify some people, but the vast amount — as much as 97 percent — are eligible.
As a variation of LASIK surgery, the Laser Blended Vision procedure is pain-free and incredibly quick. The time between entering the clinic and walking out can be as little as 20 minutes.
After the surgeon numbs your eyes with drops, a laser creates a tiny flap in the outer layer of the cornea. The flap is then lifted back and the tissue underneath adjusted according to your individual profile.
Laser Blended Vision adjusts each eye in similar but slightly different ways. One eye is adjusted to see mostly at distance, while a little up close, and the other is adjusted to see mostly up close, while a little at a distance. Your brain quickly adapts to this, combining the two images to create one of heightened visual acuity both up close and afar.
The surgeon then replaces the flap and your eyes immediately get to work adhering the edges of the flap to the cornea and calibrating your new vision.
