sorts of laser eye surgical procedure are used at London Imaginative and prescient Clinic?

Given its identify, the significance of expertise within the discipline of Laser Eye Surgical procedure ought to come as no shock. Developments in expertise haven’t solely improved the security and efficacy of the process through the years, however they’ve additionally helped to make Laser Eye Surgical procedure an choice for increasingly individuals. The truth is, extra individuals than ever earlier than can now profit from the remedy – with the best expertise.

At London Imaginative and prescient Clinic, we’re lucky to have entry to one of the best Laser Eye Surgical procedure expertise on the planet. As Mr. Glenn Carp explains within the video under, now we have a robust relationship with Carl Zeiss Meditec – a German firm that persistently develops essentially the most revolutionary Laser Eye Surgical procedure gear (generally with the assistance of our founder, Professor Dan Reinstein!). This permits us to have entry to essentially the most up-to-date expertise, permitting us to supply the very best outcomes to each one among our sufferers.

However ‘what sort of applied sciences does Laser Eye Surgical procedure require?’, You would possibly marvel. Let’s have a look.

Laser Eye Surgical procedure Know-how Defined…

Laser Eye Surgical procedure requires a lot of specialist gadgets that are used at each step of the method, together with:

• Screening sufferers to see if surgical procedure is suitable (suitability)
• Making a pre-operative evaluation
• Offering remedy
• Offering post-operative care

For one of the best outcomes, this usually includes 5 Laser Eye Surgical procedure applied sciences:

• Topography
• Pachymetry
• Pupillometry
• Wavefront aberrometry
• Excimer lasers

So, let’s take a more in-depth have a look at every of those applied sciences.

Topography

Topography is likely one of the most essential security components in figuring out your suitability for Laser Eye Surgical procedure. It’s a state-of-the-art expertise that enables us to measure the depth of the cornea and offers us an in depth map of the remedy space; this seems much like a map of a mountain vary with completely different elevations proven in contrasting colors. That is essential when figuring out whether or not the corneas are too skinny for Laser Eye Surgical procedure.

There are completely different ranges of topography in Laser Eye Surgical procedure; essentially the most fundamental sort of topography measures the form of the floor on the entrance of your eye. Essentially the most detailed topography measures the form of each the back and front surfaces of your cornea.

As Mr. Glenn Carp explains within the video under, topography additionally permits us to display for sure circumstances like keratoconus the place there’s some irregularity to the general form of the cornea.

Widespread topography machines are the Orbscan™, the Pentacam™ and the Galilei™. At London Imaginative and prescient Clinic, we use Orbscan II to carry out corneal topography. That is thought of the ‘gold normal’ world wide because of the sheer variety of factors it is ready to measure on the floor of the attention. We carry out topography each earlier than and after Laser Eye Surgical procedure remedy.

Pachymetry

Pachymetry is one other check used to measure corneal thickness. We use a handheld machine – known as a pachymeter – to measure the depth of the thinnest level of your cornea. That is carried out alongside topography to make sure the best security requirements when figuring out your suitability for Laser Eye Surgical procedure.

Utilizing each pachymetry and topography, we’re capable of accumulate essentially the most correct knowledge, making certain that the thickness of the corneas is inside acceptable security limits for remedy. As Mr. Glenn Carp explains within the video above, at London Imaginative and prescient Clinic, we use the Artemis Perception 100 – a really high-frequency ultrasound-guided pachymetry machine.

Pupillometry

Because the identify suggests, pupillometry measures the scale of the pupils – the black home windows that permit gentle into your eye. The scale of the pupils varies relying on the sunshine circumstances so, to ensure we precisely measure your pupil measurement, pupillometry takes place in a darkened room to make sure your pupils are open totally.

Mr. Glenn Carp explains extra within the video under:

Correct pupillometry is essential as we are able to solely deal with an outlined space of the attention. Usually, it is a round space with a diameter between 6mm and 8mm, relying on the laser used. If the pupil is bigger than this remedy space, you’ll be left with an untreated ring on the edges of your imaginative and prescient. Basically, this may be like wanting by way of a transparent patch in the course of a smeared window.

The outcomes of the pupillometry will assist to find out the kind of Laser Eye remedy required – or whether or not you’re appropriate for remedy in any respect. Some clinics, like London Imaginative and prescient Clinic, are capable of deal with bigger pupils due to their entry to particular lasers and programming.

Wavefront Aberrometry

Wavefront aberrometry permits us to determine imperfections of the attention that can’t be corrected with glasses alone. These optical imperfections are generally known as higher-order aberrations. They might have an effect on your cornea and optical system and trigger impairment to your imaginative and prescient along with your refractive error (i.e., myopia, hyperopia, presbyopia or astigmatism).

There are completely different requirements of aberrometer, every of which information a unique variety of measurement factors throughout the remedy space. The variety of factors usually varies from 60 to as excessive as 1200, with extra factors offering a extra detailed image of your optical system. The newest aberrometry machine makes use of a unique measurement system, producing photographs with a decision of 40,000 factors.

Throughout your preliminary session, we are going to carry out wavefront aberrometry whereas your pupils are each dilated or undilated. This permits us to collect correct knowledge concerning any higher-order aberrations in your eyes. As Mr. Glenn Carp explains within the video above, if we determine any higher-order aberrations, we are going to supply a wavefront-guided part in your private remedy plan. This permits us to attain the perfect outcomes on your imaginative and prescient post-surgery.

Excimer Lasers

To date, now we have centered on the expertise we use earlier than we even get to the remedy of your refractive error. However after all – you may’t carry out Laser Eye Surgical procedure with out lasers. As we talked about firstly of this text, we’re honoured to work carefully with Carl Zeiss Meditec, one of many world’s main producers of Excimer Lasers.

This working relationship permits us to supply our sufferers remedy with essentially the most revolutionary excimer lasers, together with the Carl Zeiss MEditect VisuMax Laser (the one femtosecond laser appropriate for the “keyhole model of LASIK: ReLEx SMILE) and the Carl Zeiss MEL 90 Excimer Laser. Every of those gadgets options cutting-edge eye-tracking expertise.
