What’s so special about wavefront LASIK

Every type of Laser Eye Surgery is referred to as the best, most effective, most advanced type—it all depends who you’re talking to.

For the majority of people new to the market of Laser Eye Surgery providers, they experience a feeling of slowly becoming entangled in a net of medical terminology and marketing promotions and personal opinions that gradually twists and tangles around them, making it more and more difficult to get out from and form a clear and conclusive decision.

High street providers help drive the confusion due to their need to attract huge volumes of customers and turn a profit from their low treatment prices. Each person through the door is a potential and well needed sale, and as we’ve seen in the Which? investigation of Laser Eye Surgery in the UK, this can lead to nontransparent pricing, over promotion of treatments, and poorly informed customers.

Wavefront guided LASIK is one such treatment that has received a lot of publicity in particular—although you may not know it. Custom LASIK, UltraLASIK, UltraLASIKplus, Wavefront guided LASIK, Accu-wave LASIK, Zyoptix; you may have come across these seemingly different treatments offered by clinics, when in reality they are generally referring to the same thing—wavefront technology.

Underneath the different names, different prices, and often different claims (some clinics even promote wavefront as the cure to all vision imperfections), wavefront is actually pretty simple—it’s not a treatment in itself, but rather an additional way to measure the eye.

In this short video Professor Dan Reinstein explains a little bit more on how wavefront measurement works:

Do I need wavefront treatment?

Wavefront error makes up around 5% of our vision, accounting for the finer quality aspects beyond common refractive errors such as long-sightedness, short-sightedness, and astigmatism which are commonly corrected by glasses.

These unique imperfections on the surface of the eye are only measurable with a wavefront aberrometer. Aberrometers can vary in their ability to analyse irregularities according to the strength of their resolution. If we build on Prof Reinstein’s analogy, we can look at the spectrum of detail being like that found among different camera lenses. While a digital camera is able to analyse an environment and map a picture precisely due to its higher resolution, a Polaroid camera fails to pick up on smaller details, creating a somewhat vague representation of the scene.

This is important as aberrometers can range in resolution from as little as 60 numbers of spots up to 800. At the top end—where you’ll find the Zeiss WASCA we use here at London Vision Clinic—aberrometers map wavefront errors in extremely precise detail—much like that of a high resolution photograph. Looking down toward the lower end, the detail actually drops past that of a polaroid, and seems more like that of a watercolour painting.

Wavefront technology is a step forward in our ability to effectively map optical errors and should be available to all LASIK patients, rather than being considered as a magical and pricey optional extra. All our LASIK treatments are guided by a wavefront aberrometer if necessary—without any added costs or unfounded claims. You also don’t need to worry about convoluted terms or long lists of treatment types, our approach is simple, along with our options—just simply ask for LASIK and our expert surgeons will guide you through what would be the best option for you and your eyes.
