Our Eye 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.

Meet with our Keratoconus Specialist in Lancaster & York , Pennsylvania to define your eye's condition and ways for treatment.

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 contacting us for a thorough eye exam.

Causes of Keratoconus

Small collagen fibers hold your cornea in place. 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 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 Specialist in Lancaster County, Pennsylvania has years of experience identifying the various levels of keratoconus and other corneal conditions.

Symptoms of Keratoconus

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

Typically, the patient’s eyeglass prescription will change often as the vision becomes worse, and contact lenses will be difficult to wear because of discomfort and improper fit.

When keratoconus becomes more severe (which usually takes a long time; however, it can occasionally happen rather quickly), the cornea can swell and form scar tissue. This scar tissue can cause even further visual distortion and blurred vision.

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 examine for the 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’ll measure the shape of your cornea. Computerized Corneal Topography is used for this procedure, which takes a picture of your cornea and analyzes it instantly.

Our Treatment Options for Keratoconus

The first line of treatment is usually new prescription eyeglasses. If this solution doesn’t help you achieve good vision, then contact lenses will be tried. Rigid, gas permeable lenses are typically prescribed.

As the disease progresses, however, glasses and soft contact lenses may no longer correct vision and soft lenses may become uncomfortable. This is when other forms of vision correction will be recommended.

Gas Permeable and Scleral Contact Lenses

For increased comfort and visual acuity at the more advanced stage of keratoconus, doctors may opt for rigid gas permeable (RGP) contact lenses, scleral or semi-scleral lenses. Since they are more rigid, RGP and scleral lenses are able to create a smooth, round shape around the cornea, creating a smoother surface for better vision.

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.

Many patients find these more comfortable than regular RGPs and find that they move around less when the eyes move. The main disadvantage of these rigid lenses is that for some, they are somewhat less comfortable than soft lenses and must be continually refitted as the shape of the eye changes.

Whether it is glasses or contact lenses being used to correct vision, patients will likely have to undergo many tests and prescription changes as their vision needs to change.

Intacs

Intacs are small, surgically implanted plastic inserts which are placed on the cornea to flatten it back to shape. Usually, they are able to restore clear vision with the continued use of glasses. Intacs are often recommended when contact lenses and eyeglasses are no longer able to correct vision adequately. Intacs take about 10 minutes to insert and can delay the need for corneal transplant.

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 created. PTK, a specialized procedure, can smooth out this scar, enhancing contact lens comfort.

Cornea collagen crosslinking

Cornea collagen crosslinking is another therapy that has shown to be effective in slowing the progression of keratoconus. An alternate remedy is called intacs, which are semicircular implants inserted under the surface of the cornea to flatten the bulging cone shape and give better vision.

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.

Our Keratoconus Specialist in Pennsylvania is happy to meet with you for a 1-on-1 consultation to get you back on the path to reaching clear vision.
