For LASIK laser eye surgery safety, there are 3 things you must look for when you plan to go ahead. This LASIK safety trio means a more accurate result and the safest procedure we know of today:

1. Choose a blade-free all laser LASIK technique – using the latest femtosecond lasers means no blade is used in the surgery. Check with any clinic you talk to that they can offer blade-free LASIK – if they can’t then they are out of date and should be avoided.
2. Wavefront-based LASIK is a must today, so make sure you go for that option. For example, at FOCUS Laser Vision we only do wavefront treatments so that is taken care of. At other centres such as Optical Express, do not choose their non-wavefront option.
3. Get the safety and reassurance of NHS consultant corneal specialist surgeons to do your treatment – the three laser eye chains do not offer this for the great majority of their treatments. Premier centres like Moorfields Eye Hospital, Centre for Sight and FOCUS Laser Vision do.

If you read yesterdays post you are up to speed on wavefront technology. OK, so far so good. It seems wavefront correction improves quality of vision after laser eye surgery. And indeed clinical trials confirm that vision results are much better after laser makers added the ‘wavefront‘ upgrades to their machines.

For example, the American made VISX lasers, used at all Optical Express laser clinics, have much better results when using their wavefront upgrade from 2002. I would not recommend having laser eye treatment today in 2008 without choosing the wavefront package on that system.

Wavefront laser eye surgery - is it the whole truth?

So now you want ‘wavefront‘ in your laser eye treatment! Of course, as the results are better. But when laser manufacturers introduced ‘wavefront’ they actually bundled in other improvements which may account for much of the jump in results! They just didn’t tell you. Why? Because it is complicated to describe all these improvements to someone who isn’t familiar with the technology – such as you, the patient!!

And honestly, I bet the sales people at most clinics talking on the phones who want to sell you a consultation don’t really understand it either! However, they have been trained to explain the wavefront part only, as something like this… “we take a scan, a unique fingerprint, of your vision and the use that fingerprint to perfectly correct your vision“. Go on, call them and check it out!

But for you, as a patient or customer, don’t really care about which part of that technology is helping you the most, you just want great vision, right?

So don’t let clinics blind you with science about wavefront scanners, wavefront maps, measuring hundreds of points of light or how much better their scanner is than other clinics scanners. It is usually marketing spin! Take it all with a pinch of salt.

However, you should choose the ‘wavefront option’ because within that package are the big improvements in laser eye treatment over the past several years. The success of surgery may actually be less to do with the true wavefront technology that has helped astronomy, but rather other improvements that may be confusing to patients but get wrapped up in the marketing of wavefront LASIK.

We come back to ethics again here. Is it ethical for some clinics to still sell ‘non-wavefront’ laser eye surgery technology that was replaced back in 2002?

For my own clinic, we do not offer non-wavefront treatments at all. None at all. I want every one of my patients to have the benefit of the newer laser eye surgery results. So we made it very affordable. In fact, we charge less for wavefront LASIK than other clinics do for their ‘entry level’ lower price non-wavefront LASIK. Really.

That’s my plug for FOCUS done! So, do choose wavefront but don’t pay more than you have to!

To recap from earlier this week, there are two ways you can upgrade your laser eye treatment: (1) upgrading on the quality of the final vision (you will see better afterwards) and (2) improving the safety and accuracy of the laser eye surgery. These are upgrades on what used to be the best treatment only a few years ago, which is known as non-wavefront LASIK and using a blade device to cut a thin flap in the surface of the cornea (the clear window at the front of the eye).

Upgrading on (1) involves paying for what is called ‘wavefront‘ laser eye surgery over ‘non-wavefront’.

Upgrading on (2) means getting rid of a metal razor-type blade in favour of a laser for the first part of the LASIK treatment (lots of names here… blade-free, dual laser, femtosecond, Intralase, Ziemer, Z-LASIK).

Kay’s questions have been about: is it really worth it to pay more? The short answer is that, yes, you should always look for ‘wavefront’ laser eye treatment. But why?

Well, the reason for this is not as obvious as laser eye clinics may tell you!

Wavefront refers to a technology adapted from astronomy which allows better resolution and clarity when looking at images of space. The principle is to remove tiny imperfections of focus, rays of light that are not getting focused properly and which cause blurriness, glare or hide details. Let’s look at an example from astronomy. In this image you can see how a blurry image of a star was improved though wavefront technology to reveal in fact two stars, known as a ‘binary star’.

'Wavefront' laser eye surgery can improve quality of vision

These imperfections of focus (known usually as aberrations) are not corrected by glasses. They are still there even after putting on your glasses or contact lenses. So after correcting your prescription fully and getting clear vision, you can still have imperfections in your vision which are usually more obvious at night.

Check back tomorrow for the next installment and the full answer on whether it is worth it to pay more  in order to get the best vision results (at most clinics – not mine, I add, FOCUS Laser Vision! – we don’t charge extra for you to get wavefront correction! In fact we charge less for wavefront surgery than other clinics do for their non-wavefront treatments).

See you tomorrow!

Following on from yesterdays post on some key LASIK and laser eye surgery questions, lets look at these:

• Do clinics try to sell you on the most expensive treatments?
• Are these expensive treatments no better than the cheaper ones?
• Is there really any difference between blade LASIK and the newer (more expensive) blade free dual laser option?

The main point here is about more expensive laser eye treatments over cheaper ones. What is the difference?

When you buy anything you normally have a choice of quality and price, for example an HD television or more basic one. Or a Mercedes over a Fiat Punto. We all understand that more money usually gets a higher value brand and clinics typically price the surgery this way too.

There are two ways you can upgrade your treatment: (1) upgrading on the quality of the final vision (you will see better afterwards) and (2) improving the safety and accuracy of the eye surgery. These are upgrades on what used to be the best treatment only a few years ago, which is known as non-wavefront LASIK and using a blade device to cut a thin flap in the surface of the cornea (the clear window at the front of the eye).

Let’s look first at spending more to get better quality of vision than the older ’standard’ treatments (which are STILL available at most clinics, not at my centre – FOCUS, by the way, although there is a good case to abandon this older technology). The high street chains (Ultralase, Optimax and Optical Express) all offer two levels of surgery for quality of vision.

The basic cheaper treatment is called by various names but all are what are termed ‘Non-Wavefront’ surgeries. For example Ultralase call it just ‘laser eye surgery’, Optimax and Optical Express refer just to ‘LASIK’.

The higher quality, better vision treatments all come under what is called ‘Wavefront’ laser eye surgery.

‘Wavefront’ simply refers to a technology that is claimed to offer higher-definition vision, especially at night time, which was introduced several years ago.

Just to confuse you there are different names, again depending on which clinic you visit! For example, Ultralase call this ‘ULTRALASIKplus‘, Optimax opt for the simpler ‘Wavefront LASIK‘, while Optical Express go for the mouthful of ‘Advanced CustomVue Wavefront LASIK‘. Other independent clinics use various names.

At my own clinic FOCUS Laser Vision, we only offer the higher quality vision ‘wavefront’ laser eye treatments. You cannot get non-wavefront eye surgery with us.

Please note that paying more at one clinic doesn’t mean you get better surgery than at another clinic. You need to look at what you are paying for. For example FOCUS Laser Vision charge less for advanced wavefront correction than most other clinics do for older technology non-wavefront treatments. Blowing my own trumpet here, I know! But paying more does not always equal getting more. More on this later.

Kay also asked in her mail about the ethics of treatment offerings and we will cover that topic in the next blog postings. Basically, is it ethical to offer lower quality treatments when newer higher quality ones are available? No-one cares about this for other products and services (is it ethical to sell Fiat Puntos when Mercedes are available?) but it can be a hot topic in healthcare. I will write on this subject during the coming week. And I will welcome your comments!

OK, but are these ‘wavefront’ treatments really better than ‘non-wavefront’? Come back tomorrow to get the truth!

You can still read Rick’s story about his treatment with me, online at the Daily Mail’s website. Rick talks about the whole process in a very interesting article from Rachel Kaufman.

Follow the link below to read the full article.

There are three main treatment choices for anyone thinking of having laser eye surgery. But which one will be right for you?

The final choice will be determined between you and your laser eye surgeon. BUT, of course, you have the eyes and your surgeon has the expertise so you will be heavily influenced by what the doctor or another clinic staff member says. It will be better to be prepared. With just a little knowledge you can be actively involved in making the right choice.

I will outline the 3 main options to help you have an informed discussion when the time comes to select which approach is best for your individual eyes. After all, you only have one pair so you want to get it right.

You will be overwhelmed at first by all the terminology, treatments and brand names. Don’t worry. There is no need to be blinded by science or some of the frankly misleading marketing information that is out there.

Firstly, whichever of the 3 treatment types (more on these coming in a couple of days in part 2) you go for, you must go for the wavefront option. The wavefront (or custom) technology has made a huge improvement in vision success rates with many more people getting 20/20 sight or even better.

Different clinics use different names for this technology: custom, wavefront, wavefront guided, wavefront optimised, CustomVue.

Many clinics will charge you more for wavefront based treatments over older non-wavefront options. Is it worth it? Definitely.

Back in 2000 when we were doing LASIK without wavefront, the benchmarks for success were getting 65% of patients to 20/20. In 2008 we expect more than 95% of patients to see 20/20 or better. This improvement has come from better technology, in large part from custom or wavefront based corrections.

Also wavefront laser eye treatment will give better vision at night or in low light situations. Patients will notice less halos and glare from light sources such as car headlights. It is like buying a more expensive camera with a much, much better lens.

This is the year 2008, so get the best current technology for your sight correction – you only will have this done once and you will live with the results for the rest of your life. Think about the computer you had back in 2000 and what is now available in 2008 – that is the level of difference in laser technology too. No brainer, really.

If you can’t afford the price, either don’t have it done yet and save up until you can afford it, or think about financing.

So if you go to Optical Express, go for the more expensive CustomVue wavefront version. Without it, the results really are not at a level that is satisfactory in 2008. If you go to Optimax or Ultralase, pay and get their wavefront guided option.

If you go to FOCUS Laser Vision, wavefront is already included in the quoted price. They don’t do any non-wavefront treatments.

Come back in a couple of days to read part 2 where we will finish this post by looking at safety and healing in laser eye surgery.

Here you have a comparison of what LASIK costs at London LASIK clinics. You can see 4 typical prescriptions and what each clinic charges – and you will see the huge variation in LASIK laser eye surgery prices!

For example, for a simple -1 dioptre correction there is an enormous variation in LASIK cost. The lowest is £295 per eye for wavefront LASIK and £595 for femtosecond laser blade free LASIK at FOCUS Laser Vision (http://www.focusclinics.com). The highest are £2145 at Moorfields eye hopspital (www.moorfields.nhs.uk) and £2250 at Centre for Sight in East Grinstead (www.centreforsight.com).

All three centres offer fellowship-trained specialist NHS London teaching hospital consultant surgeons and advanced wavefront LASIK treatments. Yet the difference in price (money you will save) is up to £3,000-£4,000 for both eyes treated for a -1D correction. For an common prescription, e.g. -2.75/-1.50 x 90, you will still save up to £2,600 from the cheapest to most expensive. And this includes teaching hospital NHS consultant surgeons at both centres, plus the best blade free all laser LASIK option. It’s a remarkable price difference.

The chart below shows prices for wavefront keratome (mechanical) LASIK laser eye surgery. Optimax and Optical Express will charge approximately £300 more per eye for all laser blade free LASIK, as do FOCUS Laser Vision. London Vision Clinic and Centre for Sight include blade free in the prices shown. Ultralase only now offer blade free LASIK but curiously still offer non-wavefront treatments, and so are not in the chart below. They charge £1895 per eye for wavefront blade free LASIK.

Check out this chart for London centres. More on this coming soon.

OK, it’s here at FOCUS Laser Vision in London. The video of our breakthrough next generation Z-LASIK laser eye surgery procedure! I can tell you the results have been amazing. Twelve treatments on our first day, and everyone can see better than 20/20, 60% of them seeing an incredible 20/12! (that’s two lines smaller than 20/20 on the vision test chart, clarity usually seen by teenagers, and approaching the finest limit of human vision) And that’s just 24 hours after treatment. Wow.

Enough talking, it’s time to watch the video. just keep rolling after the procedure to hear Bella talking the following morning about her ‘miracle’! As a surgeon, this is the best bit of the job.

Z LASIK at FOCUS in London starts from £595 per eye for short sight – FOCUS want to make this treatment affordable for everyone. You can reach the clinic on 0845 5000 500.
