Our Doctors Can Diagnosis and Treat Keratoconus

Your cornea is the transparent, outer lens of your eye, and it typically has a smooth dome shape. Keratoconus describes a condition in which the corneal structure isn’t strong enough to maintain a healthy ball shape.

As a result, the cornea bulges outward into more of a cone. Our professional optometric team at our eye care clinic is knowledgeable about how to diagnose and treat keratoconus.

Keratoconus is rare, with an estimated one person out of every 2,000 having the condition. It generally appears in the teenage years and can progress slowly or rapidly.

Keratoconus also runs in families, so if you or your children are at risk, it’s advised to contact us for a thorough eye exam.

Meet with our Keratoconus Specialists in Spring, Texas to define your eye’s condition and ways for treatment.

Causes of Keratoconus

Your cornea is held in place by very small collagen fibers. When they are weakened and too fragile, they aren’t able to preserve the round shape of your cornea.

A reduction in the protective antioxidants of your cornea, which act to destroy damaging by-products made naturally by corneal cells, is what causes keratoconus.

In addition to genetics, some types of eye injuries may increase your chance of being diagnosed with keratoconus.

Specific ocular diseases, such as retinitis pigmentosa, vernal keratoconjunctivitis and retinopathy of prematurity, as well as some systemic conditions (Down syndrome, Ehlers-Danlos syndrome, Leber's congenital amaurosis and osteogenesis imperfecta) are also associated with this corneal abnormality.

Our Keratoconus Specialists in Spring, Texas have years of experience identifying the various levels of keratoconus and other corneal conditions.

Symptoms of Keratoconus

When the shape of your cornea begins to bulge, it alters your eyesight in two different ways. As the cone shape forms, your normally smooth corneal surface becomes wavy, causing irregular astigmatism. Additionally, as your cornea expands, vision becomes increasingly irregularly shaped. Focusing becomes impossible without eyeglasses or contact lenses. Usually, the problems begin in one eye and develop later in the other eye too.

Typically, a patient’s eyeglass prescription will change often, and it might become impossible to see the 20/20 line, even with the best glasses on. When the cornea is irregular, it becomes difficult to correct the vision with traditional glasses or soft contact lenses.

As the cornea becomes more irregular, it also becomes thinner. In some patients, this can lead to complications, which can include significant scarring.

Altogether, these changes can create the following symptoms:

  • Blurred vision
  • Streaking of lights
  • Halos around bright lights at night; glare
  • Sudden change of vision in only one eye
  • Objects appear distorted, both near and distant
  • Double vision from just one eye
  • Triple ghost images

How We Diagnose Keratoconus

Our eye doctors will inspect carefully for signs of keratoconus during your comprehensive eye exam. It’s critical to inform us of any symptoms that you’ve been experiencing. To diagnose the condition, we will use Computerized Corneal Topography to measure the shape of your cornea. This instrument is critical in making the diagnosis of Keratoconus. Corneal Pachymetry, which measures corneal thickness, is also very important for diagnosing Keratoconus and monitoring for progression.

Treatment for Keratoconus

The first line of treatment is usually new prescription eyeglasses. If this solution doesn’t help you achieve good vision, then one or more of the following treatment options may be discussed.

Gas Permeable and Scleral Contact Lenses

When the cornea is not smooth and regular, it can be difficult to achieve clear vision with glasses. For those patients, rigid gas permeable (RGP) contact lenses provide much clearer vision. RGP contact lenses are small in diameter and use the tear layer behind the lens to create a smooth surface to help patients see more clearly.

Scleral or semi-scleral lenses have a larger diameter which covers the entire cornea and reaches over into the white part of the eye, which is known as the sclera. Because these lenses are highly customizable, it sometimes takes a few prescription changes to find lenses that are comfortable, provide the best fit to maintain good corneal health, and provide the best vision. Scleral and RGP lenses should be changed annually.


Intacs are small, surgically implanted plastic inserts which are placed in the cornea to flatten it. Sometimes they are able to restore clear vision with continued use of glasses.

PTK for severe keratoconus

Severe keratoconus may lead to extreme scarring, due to overstretched collagen fibers. If the back of your corneas tears as a result, swelling may occur. It can take months for the swelling to go down, and a large scar is generally created. PTK, a specialized procedure, can smooth out this scar, thereby enhancing contact lens comfort.

Cornea collagen crosslinking

Cornea collagen crosslinking is a therapy that has shown to be effective in slowing the progression of Keratoconus. Riboflavin eye drops are used, and when the cornea is saturated with these drops, a focused beam of ultraviolet light is used for a set amount of time. This treatment causes the collagen fibers in the cornea to link up, causing the cornea to become stronger, thus slowing or halting the progression of Keratoconus.

Cornea Transplant

As a last resort, a cornea transplant may be performed. During this procedure, the center of your cornea will be removed and replaced with a donor cornea. The new cornea is stitched into place, and you’ll need to wear contact lenses for adequate vision after the surgery.

Dangers of LASIK and Keratoconus

LASIK can potentially weaken the cornea of anyone who suffers from keratoconus, making it a dangerous procedure. If this happens, your vision will become substantially worse. Even if your keratoconus is mild, LASIK is not an option.
