Laserfit wavefront scleral contact lenses.

Laserfit Wavefront Scleral Contacts Lenses dramatically improved my vision, lens comfort and wear time.

 

I have recently returned from Dallas where I was fit with Laserfit wavefront contacts. They are, without a doubt, the best contact lenses I have ever had! The vision is amazing, its High Definition compared to anything else I have ever tried and the comfort is amazing. I have tried a lot of contact lens and visited numerous optometrists in different countries, nothing comes close to the Laserfit lenses. My optometrist has never seen anything like the results I got from Laserfit lenses. I have tried scleral/semi scleral lenses in the past but these are nothing like them.

 

The whole fitting process is somewhat future like, I imagine in 10-15 years it will be the standard. It's all computerized. There are no time consuming and excruciating trial lens fittings to endure instead the eyes are scanned with an OCT machine, that process takes about twenty minutes. The data from the machine is then turned into a 3D digital mold of the cornea and from there the contact lenses are designed specifically to fit the cornea. Once that lenses have been made then it's onto the optics part of the process which involves the standard eyechart plus another machine called a wavefront aberrometer. The wavefront aberrometer can see what you see, it can even generate a picture of what you see on the eyechart! The data from the wavefront machine is then incorporated into the into the contact lens(this is why the vision is so much better than with a normal contact lenses). Being interested in the whole process I got a chance to see the CAD software that is used behind the scenes to make the lenses, it's amazingly sophisticated. The whole process is so different to a normal contact lens fitting.

 

Something that has really stuck with me. While I was there I met another KC patient who had exhausted all the conventional avenues there was nothing more that could be done for him and his ophthalmologist had said he needed to have a cornea transplant. It was his second day at the clinic and he was able to see 20/15 with the Laserfit lens!  

 

I have sent an email to Dr Gemoules(Dr G as he known by his staff and patients), the developer of the Laserfit lenses, to ask if he will come and post on this forum.

 

 

Dr G is incredibly committed to ensuring success for the patient. His staff told me he works late into the night tweaking the designs of the lenses. With me he also found binocular vision difficulties, which had been over looked by other optometrists I had visited and had made life pretty difficult. This is a topic for a whole different post!

What vision do you get with the lens?

20/15 in the better eye and in the other better than 20/20(its actually 20/16 when tested back home due to the eye chart charts here using the metric 6/6 type numbering its 6/5 which equates to 20/16 on the US imperial 20/20 numbering)

Those numbers don't really tell the whole story its the lack of ghosting, halos, glare etc that is the big win for me.

Hello BionicEyes, and thanks for the nice write-up of your experiences with Laserfit lenses. Unfortunately, it probably all seems too good to be true to the average person with keratoconus who has tried different types of contact lenses, but others have experienced your results with Laserfit. There are two key issues related to our lenses, and they are interrelated. The first issue is the wavefront-guided optics. Wavefront is not something new. It has been used in LASIK surgery for a number of years to improve the results. It has not been successfully adapted to contact lenses because of the other issue: poor rotational stability and lack of good centration of existing contact lenses. Within the past couple of years, a few papers have been published on the use of wavefront-guided optics in scleral lenses for keratoconus by a couple of research institutions, with good results.

Our first patented technology enabled us to produce lenses that positioned precisely on the eye and did not rotate. Once we saw that then we pursued the wavefront technology, for which we hold another patent. We actually use a number of different technologies to achieve optimum results, with patents pending. And so we have the first and probably still the only commercially available scleral lens using wavefront-guided optics for several years, now.

It is all a bit complicated, and requires equipment that is not routinely present in the optician's or optometrist's office. This makes it less likely that it will become widespread anytime very soon - maybe in another decade or so as BionicEyes mentioned. Perhaps it could be pushed or accelerated if demand was there.  I originally pursued the technology to help the patients already in my practice to see better, not as a business venture, and that is still the case.  It should also be said that I started working on this in late 2007.  It is now the beginning of 2015 and still surprisingly little awareness or understanding of this exists outside of the narrow halls of academe.

Cheers,

Dr. G.

Thank you Dr G for your post. From reading about this development, I believe this is a very robust solution, when this needs to be relied upon, and which in most cases - a roust solution is what is needed, and its make or break time (can it get any better for Sclerals?), as the visual goal can be optimized through more finer customization of the optics to "fit" the very individual KC.

There will be resistance from the old school (we have seen this time and again for other developments), but please press ahead like you have been to advance technology and development.

Thank you, Deb for your encouraging words.  The discovery of this technology predates my work by at least 7 years.

Dr G,

If you want to share, you can, by adding any attachments/presentations on to this or any thread you want to start or contribute to.

Is there a course you can develop for the continuations education of Optometrists ?

Wayne

Wayne, surely I can make further contributions once I know people are interested in the technology.  Naturally my book is always full, but this is but a drop in the proverbial bucket compared to the need.

The proper implementation of this technology does require some investment on the part of the optometrist - not only in equipment, but also in specialized training.  It would probably not benefit the occasional fitter.  Perhaps a network of dedicated specialist clinics would be required.  This is the sort of thing where the fields of optometry, optics, and engineering meet.

But at least we can continue with the discussion for informational purposes.  My website does contain quite a bit of information that probably cannot be duplicated here, including case reports.  So if anybody has the chance, a visit would be worthwhile.
