Do you have Keratoconus or other corneal dystrophies? Back when Dr. Barry Leonard was first diagnosed with Keratoconus in the 1980’s, not a lot was known about diagnosing Keratoconus, and even less was known about how to treat it effectively. That left Dr. Leonard with dry eyes, red eyes, eternal discomfort from his contact lenses, and the inability to see clearly most of the time. Today, the cKlear Method™ for Keratoconus and other Corneal Dystrophies, which was developed at the California Keratoconus Center, is the leading state-of-the-art method for the diagnosis and non-surgical treatment of Keratoconus. So if you have Keratoconus, you finally have the opportunity to see clearly with the cKlear Method.
Keratoconus is a somewhat rare condition where the cornea forms in a cone shape. Normal corneas are symmetrical, smooth and round. In people with Keratoconus, the cornea protrudes out in one or more bulges or “cones.” These bulges distort vision and makes the eye more sensitive to glare. So what is Keratoconus? Simply put: It’s a cone-shaped eye.
It is difficult to treat Keratoconus with glasses, because light entering the eye from different angles is refracted differently by the cornea. That makes correcting the moving eye with a stationary lens in a pair of glasses nearly impossible.
And conventional contact lenses don’t work well for Keratoconus either, because contact lenses are designed to be mostly symmetrical and to rest directly on the cornea. That doesn’t work well on a bumpy cornea, which results in poor vision and an incredibly uncomfortable lens.
Conventional lenses also don’t work at all for patients who have High Order Aberrations (HOA) — glare, streaks, ghosting, and halos — that can make your life even more of a challenge than your Keratoconus.
Today, most Optometrists and Ophthalmologists diagnose Keratoconus much like it was done in the 1980’s. An instrument called a Keratometer is used to look at the cornea, which superimposes rings called “Mires” on the cornea. These mires illustrate the elevation of the cornea, much like latitude rings on a globe when viewed from the North Pole. A normal eye will have perfectly round mires, and an eye with Keratoconus will have oblong, irregular and misshapen mires.
The problem with a conventional Keratometer is that it generally looks at the center 3 millimeters of a cornea, which is only about 10% of the cornea and none of the Sclera — the white part of the eye. The eye doctor will use his own vision to estimate Keratoconus on the rest of the eye.
Other eye doctors may have another instrument called a Topographer, which shows the “topography” (bumpiness) of up to 50% of the cornea and 0% of the Sclera. That’s better than a Keratometer, but still falls short for an accurate Keratoconus diagnosis. That means the eye doctor still needs to estimate and guess at the complete prescription for a Keratoconus contact lens.
The rest of the Keratoconus is diagnosed visually using a microscope, which typically does not have an integrated camera system. That means that the eye doctor has to work from notes and from memory, and then rely on his or her own experience to design a Keratoconus contact lens.
Keratoconus contact lenses designed this way usually require 4, 5 or more different lenses be designed, fit, tested, and worn until the fit is “good enough.” That generally means a 1-2 week interval between each fitting, and each requires another visit to the eye doctor for the fitting.
In other words, the process is “Trial and Error…and Error…and Error.”
While this may be the best that many Keratoconus patients have ever seen, it’s not nearly as good as is possible with the cKlear Method.
Our focus at the California Keratoconus Center is to help Keratoconus patients see clearly and comfortably without surgery. So the cKlear Method uses the latest technology and the most accurate instruments, as well as a rigorous 6-Step Process — or a 7-Step Process if you have High Order Aberrations — to deliver the clearest, most comfortable vision possible.
Eye doctors are taught in Optometry school that “People are entitled to more than one problem,” so if you have Keratoconus, it unfortunately may not be the only problem you have. That’s why the first step in the cKlear Method is a comprehensive eye exam.
This exam can reveal a variety of other issues which not only require treatment, but may affect your Keratoconus Treatment. These issues could include…
…and more. If you’ve recently had a comprehensive eye exam and were referred to the California Keratoconus Center by your doctor after a preliminary Keratoconus diagnosis, we can rely on the prior exam.
The cKlear Diagnostic Exam is our first look at the topography of your eyes. We use a very precise instrument called the Nidek OPD III to examine and document the surface of your cornea. With the OPD III, we can…
We then use a special Slit Lamp Microscope with a FireFly HD Camera System. With this instrument, we can…
If we were to stop here and design lenses for you, your vision and comfort would likely improve over what you have now. But the cKlear Method is just getting started.
At this point we can determine if you have Keratoconus, the type of Keratoconus, the severity of your Keratoconus, and have a good understanding of your best Treatment Options. On only extremely rare occasions might we recommend a visit to an Ophthalmologist for corneal surgery — but this is only when the cornea is in very, very poor shape, as with severe corneal scars or hydrops or if your Keratoconus is progressing rapidly.
In the overwhelming majority of cases, we can continue with the cKlear Method and recommend treatments for you. These options are based on the best contact lens for your diagnosis and your budget, and include four different types of contact lenses.
All of these lenses have their strengths and appropriate uses. We will recommend the best lenses based on our diagnosis and consultation with you. Among the Scleral lenses we most often prescribe are:
We will recommend the best lens and alternatives for you based on your diagnosis, your budget and your insurance coverage.
Once we’ve chosen a treatment plan, it’s time we get to the details of your eyes that 90% of other eye doctors don’t have the training, experience or equipment to see.
The Zeiss OCT is an “Optical Coherence Tomographer” that allows us to view your eye to 2 microns. We can look at your Corneal and Scleral Profiles around all 360 degrees of your eye, and measure the thickness of your cornea, both of which can affect prescription and lens design
Based on your symptoms or our prior evaluation on the Nidek OPD III, we may discuss your High Order Aberrations. We can measure your HOA profile on the Nidek or the Ovitz Ares Aberrometer.
We see many Keratoconus Patients who were previously fit with Intacs Corneal Inserts or implants. These are small plastic rings intended to resolve or improve your Keratoconus. However, what often happens with Post-Intacs patients is that the back sides of their corneas will bend, resulting in High Order Aberrations.
The Nidek OPD III and the Ovitz Ares Aberrometer both allow us to see the Optical Light path into the eye, which allows us to view your High Order Aberrations.
The result is that we can “see what you see”, including streaks, glare, ghosting, double and triple vision and more. When we show our Keratoconus patients the screen on the OPD III’s or Ovitz Ares Aberrometer and ask “Is this what you see?” we often see tears, because this is the first time in their lives they’ve ever been able to share with someone else the vision problems they have.
It’s an emotional time…but it doesn’t compare to what’s coming soon.
The Eaglet Eye Surface Profiler is a full-featured topographical tool that allows your Optometrist to take highly accurate measurements of your cornea, Sclera and limbus (the area between the sclera and the cornea). The Eaglet can see and measure over 350,000 separate points across a 20mm area to precisely and accurately map every tiny detail in your eye’s surface, including 100% of your cornea and as much of the Sclera as we need.
The Eaglet gives us a 3D image or map of your complete eye that we can rotate and tilt to show you the exact surface of your eye. For the first time, you will be able to see your Keratoconus. We use this same information, in meticulous detail, to design your lens.
If we have chosen either the BostonSight FreeForm lens or the ScanFit Pro lens, data from the Eaglet is sent directly to the contact lens labs, where your custom lens is manufactured. While on rare occasions, we may need or want to make small tweaks and adjustments, these lenses get us 98% of the way to a perfect fit.
In other words, the days of “Trial and Error…and Error…and Error” are over.
These first four steps typically happen within your first visit to the California Keratoconus Center, and typically lasts about an hour to an hour and a half.. It’s at this point that we will design and order your new Keratoconus Contact Lenses. We will schedule your next visit, called the Dispensing Visit, in about 5 to 10 days, when your lenses are created. In some cases, we can even rush lenses to be ready in as few as 2 days.
Welcome back! You’ve been anticipating this moment for a long time. You’re about to “See Clearly with the cKlear Method” for the very first time. And it’s an exciting time.
Whatever kind of lenses we’ve ordered for you, we’re going to teach you how to use them. Our highly trained, patient and compassionate Contact Lens Technicians will teach you how to apply, remove, clean, store and take care of your lenses. You will learn how and when to use your contact lens solutions, and we will practice inserting and removing them.
Let’s not skip over the fun part.
You are sitting in front of a mirror at our Contact Lens Training Station. You’ve received your lesson on how to put in your lenses and you’re putting them in for the first time. Sure, it may take a time or two to get used to doing it, but they’re now in and you’re opening your eyes and…
And…WOW! Who is that good looking person on the other side of that mirror! It’s YOU! It’s YOU like you’ve never seen before! For many of our patients, it’s the first time they’ve seen themselves clearly in a lifetime. And almost all of them quickly turn around to gaze across the room. “Hey,” they say. “I can read the sign on that wall over there!” and “Wow…I’ve never seen actual strands of hair on people before…just hairy blobs on heads.”
Some of our patients quickly walk into our front office and stare at the colorful displays around the room. Still others rush outside to see the trees. They can’t believe what they see. LEAVES! Yes, many of our patients have never actually seen leaves on trees before.
And if they were driven to their appointment by someone they love — and that’s often the case because many Keratoconus Patients are too afraid to drive, especially at night — they turn to that person and give the biggest smile of their lives because they’ve never seen someone so beautiful.
It’s a VERY emotional time for our patients. And hopefully will be for you, too.
Before you rush out of the office to explore the world, we want to check one other thing: the fit. Because it’s not just enough for you to see clearly, we want you to see comfortably, too. We’ll check the fit, the comfort and even the physiology. We’ll put you back on the Zeiss OCT and examine how well your lens fits your eye. If your lenses aren’t perfectly comfortable, we’ll make another set at our expense.
But with the cKlear Method, more often than not, our patients experience First Fit Success with their Keratoconus Contact Lenses.
It’s at this point that you may want to make a short testimonial video, so you can tell the world about what it’s like to see clearly and comfortably. We’d love to add your story to our library of cKlear Method patients.
Even though you are seeing more clearly and more comfortably than you ever have in your life, you’re not done with us. We’ll schedule the next step in your treatment, the cKlear Progress Checkup, a couple of weeks after your Dispensing Visit, and then at 3 to 6 month intervals. We want to make sure your Keratoconus isn’t progressing, that no new eye issues arise, and that your lenses continue to fit well and allow you to see well.
At this point, your lenses are feeling great and you are enjoying better vision than you’ve ever had. Apart from your Progress Checkups, the cKlear Method is complete for most patients.
However, if you also have High Order Aberrations, then there is one more step in the cKlear Method.
High Order Aberrations occur at specific locations on your eye. That means that resolving your HOAs can only happen after we’ve got a perfect fit for your Scleral lenses, which are designed to remain stationary on the Sclera of your eye.
So after your Progress checkup, we will order a special “alignment lens”, which is shaped exactly like your new contact lens. You will come in for a special cKlear High Order Aberrations Design visit, during which we will put this alignment lens on your eyes and use our Aberrometer to precisely measure your HOAs as they pass through your eyes and lenses.
When your new HOA lenses arrive, you’ll return to try them on. Over time, as you go about your daily life — including driving at night, being outside with city lights all around you, movie theaters or among other bright lights — you will experience life with little if any HOAs. And if any remain, we can schedule another follow up visit to remove even more of your HOAs.
We hope you understand the cKlear Method a bit better now, and why it is so much more advanced than any other non-surgical Keratoconus Treatment available. If you have Keratoconus and are ready to see clearly and comfortably for the first time in your life, make your cKlear Method appointment today by using our online appointment form or calling the California Keratoconus Center at 818-891-6711.
