In honor of National Doctors Day 2017, the National Keratoconus Foundation asked their newsletter subscribers to tell them why their eye doctor was special. Dr. Blaze is among the forty practices of ophthalmologists and Optometrists who provide outstanding care to their KC patients.

Dr. Blaze is on the cutting edge of all the new techniques, products, and lens designs, determined to find the right fit for his Keratoconic patients.

Keratoconus

Keratoconus is a corneal disorder in which the cornea is thinning and becomes distorted.

The progression is generally slow and can stop at any stage from mild to severe. As Keratoconus progresses, the cornea tends to bulge, which causes the corneal tissue to thin. As the thinning progresses, the corneal shape becomes irregular and scarring may occur.

Causes of Keratoconus

The cause of the disorder is not yet known, but there’s a strong suggestion that genetics play a role.

There is still much research in progress attempting to find an answer to this ongoing question. One theory is that the corneal thinning is associated with enzyme balance. The imbalance makes the cornea more susceptible to oxidative damage from compounds, which weaken it and bulge forward and/or scar.

Symptoms of Keratoconus

People who have Keratoconus typically present with a mild astigmatism correction, usually at the onset of puberty.

Generally, one can be diagnosed by their late teens to early 20’s. When children are diagnosed at an earlier age, it indicates a greater risk of severity of the disorder.

The patient’s vision tends to fluctuate, which drives them to change their contact lens prescriptions quite frequently. For some, the disorder and prescription are stable for years or indefinitely. For others, it may progress quite rapidly. Most often, Keratoconus progresses for a period of about ten to twenty years before it generally stabilizes. A new procedure called collagen crosslinking help stabilize the corneal thinning.

With mild forms of Keratoconus, spectacles or soft contact lenses may help, but as the disorder progresses and the cornea becomes more irregular and thinner, the harder it is to correct the vision with glasses or soft contact lenses. The vision becomes inadequate. The rigid lens material enables the contact to cover the cornea and smooth its irregular shape. This will significantly improve the vision.

Treatments of Keratoconus

The following are how keratoconus is treated – specialty contact lenses, Corneal Crosslinking, Corneal Transplants, and INTACS. Not every keratoconus patient is a candidate for any or all of these procedures, Dr. Blaze will be the person to assess the best treatment options for your eyes.

We are seeing a lot of patients getting directed to aggressive surgeons for corneal crosslinking for keratoconus or corneal transplants, many patients don’t need these procedures and should have contact lens fittings as the primary treatment.

  • Collagen Corneal Crosslinking:

CXL is a nonsurgical procedure takes about an hour. The treatment strengthens the weak corneal structure by allowing collagen fibers in the stroma to form new bonds to each other.

The result is that the progression of Keratoconus stops or is slowed. CXL does not reverse Keratoconus changes that have already occurred. That is why this procedure is recommended for those who are recently diagnosed or whose Keratoconus is still progressing. The large majority of CXL is done on patients in their 20s or 30s, and only rarely done in the 40s when Kconus stabilizes.

  • Corneal Transplant:

It has been more than 80 years since the first corneal transplant was performed on a patient with keratoconus. It remains the standard of care for the most severe cases (central scars), where comfort and useful vision cannot be achieved with contact lenses. After corneal transplant surgery, whether full- or partial-thickness, the corneal surface irregularities may be reduced, but you will likely still need vision correction. With a new cornea, contact lenses are often better tolerated.

Many patients fear they will need to undergo a corneal transplant when they learn they have keratoconus. In most cases, there will not be a need for a transplant: more than 75% of individuals with KC do not require a corneal transplant. However, if needed, corneal transplantation using current eye-banking and surgical techniques is a very successful procedure. Dr Blaze is associated with the best surgeons in Orange County.

  • Intacs:

Intacs® Corneal Implants are an ophthalmic medical device have been used with keratoconus to smooth the irregular surface. Intrastromal corneal ring segments (ICRS) are clear, arc-shaped implants made of synthetic material that are surgically placed into precise tunnels created in the outer edge of the cornea. However, given the improvement with scleral contacts and corneal transplantation, Dr Blaze believes this treatment is marginally beneficial and not recommended.
