This problem is often misunderstood. There is a common misconception concerning laser eye surgery that many eye doctors spread: “Laser eye surgery is only beneficial for young people. It just serves to remove people from their reading glasses and has no effect on distance vision. This is not true.
The Solution: Blending Vision Eye Surgery with Laser
In the last 5-10 years, there have been many advancements made to address this issue. Different laser platforms have adopted various strategies.
The Zeiss MEL90 platform is, in my opinion, the laser platform that has really won out with an efficient, secure procedure using LASIK to correct reading vision. This treatment profile makes use of Presbyond blended division.
It expands on a phenomenon that arises spontaneously. In our twenties and thirties, we have the miraculous capacity to switch attention from far to close in less than a second, which is known as visual adaptation. Spherical aberration, an optical flaw, is increased to some extent in order to achieve that. One of the things that happens when we accommodate is that our attention shifts from distance to closeness. To increase the depth of focus on each eye, a controlled degree of spherical aberration is produced using the Presbyond laser blended vision program. And finally, we can ask each eye to perform a slightly different task for the vast majority of patients.
How Does Practical Mixed Laser Vision Operate?
For instance, in my case, my dominant eye is the right. My right eye would then be equipped with intermediate vision at distance. Additionally, my left eye would be used for intermediate to close vision with the Presbyond laser platform. It is essential that they cross across to create a mix zone, an area where both eyes are contributing. By doing that, I am able to focus across the entire focus range, from far away to intermediate, to close up.
Can Presbyond Give You Excellent Vision?
A compromise, indeed. It is an incredibly strong and successful treatment that gives 90% of the patient’s entire vision, independent of glasses. It isn’t like being twenty-one with perfect distant vision that you can shift fluidly to close-up and back out again.
The other patients only use readers if they wish to read for an extended amount of time or if the lighting is poor, such as late at night when they are fatigued and the lights are dim.
Therefore, the widespread misconception that laser eye surgery cannot address the requirement for reading is untrue. With laser eye surgery and Presbyond blended vision, Kraff Eye Institute can provide our patients with distance through to close-up focus, freeing them from the need for eyeglasses.
