To Our Valued Patients,

With the evolving situation of the Coronavirus (COVID-19) pandemic and under the guidelines of the Health Officer of the Alameda and Contra-Costa Counties, our offices are open to provide eye and vision care.

Please keep in mind that in order to maintain social distancing protocols and to limit further transmission of the virus, we will be working with a reduced staff and seeing a fewer number of patients as compared to our “normal” schedule. Priority will be given to the most urgent medical cases. We will be implementing a number of measures (including altered check-in/check-out procedures, limiting the number of patients in the office and waiting room, face covering for all persons, temperature screening, etc) that will change your experience in the office. In addition, we will be ramping up our already strict disinfection policies and we will continue to monitor and abide by all local, state and, federal guidelines. Please bear with us through this new reality as these changes are designed to protect you and our staff.

We hope to see you soon and appreciate your trust in us to continue to meet your eye care needs. Stay safe and stay healthy!

What Is Keratoconus?

Keratoconus (keh-rah-toe-cone-us) is a condition in which the structure of the cornea isn’t strong enough to maintain a healthy ball shape, causing the cornea to bulge outward into a shape resembling a cone. This leads to a host of symptoms, including blurred and double vision, as well as halos around objects and streaks of light.

Below you’ll learn more about this condition and discover how Dr. Chirag R. Patel at Scleral Contact Lens Center at Turner Eye Institute can treat your keratoconus to safeguard your eye health.

What is Keratoconus?

Keratoconus is a progressive eye disease in which the dome-shaped cornea thins, causing the cornea to develop a cone-like shape. The misshapen cornea deflects light, causing distorted vision, and may result in blurred vision, double vision, myopia, irregular astigmatism, and sensitivity to light.

This rare eye condition affects 1 out of every 2,000 people. It typically begins in the teenage years and early 20s, with vision deteriorating over a period of about 10 to 20 years. It’s common for people with this disease to see prescription changes with each eye exam.

Keratoconus often runs in families, so if you or your children are at risk or are experiencing any of the symptoms mentioned below, contact Scleral Contact Lens Center at Turner Eye Institute for an eye exam. Keratoconus can only be diagnosed through a thorough eye exam, where Dr. Chirag R. Patel will examine your cornea and measure its curvature.

Your cornea is held in place by very small collagen fibers. When they are weakened, they cannot preserve the round shape of your cornea. The exact cause of keratoconus, however, is still unknown.

Weakening of the cornea tends to happen in those with a genetic predisposition, which is why keratoconus may affect several people in a single family.

Keratoconus has also been linked to:

  • Excessive exposure to UV rays
  • Excessive eye rubbing
  • Difficulty wearing contact lenses
  • Certain eye injuries
  • Retinitis pigmentosa
  • Marfan syndrome
  • Ehlers-Danlos syndrome

Symptoms of Keratoconus

As the shape of your cornea begins to bulge, it alters your eyesight. Your normally smooth corneal surface becomes wavy and expands, becoming cone-shaped. This causes irregular astigmatism or nearsightedness. The condition tends to begin in one eye and later develops in the other eye as well.

Typically, one’s prescription will change frequently as vision worsens, and it will become difficult to wear contact lenses due to the expanding cornea. If the lenses are not properly fitted on someone with Keratoconus, the lenses can rub against the diseased part of the cornea. The excessive rubbing causes symptoms to worsen by aggravating the already thin cornea. When the symptoms of keratoconus intensify, the cornea can begin to swell and form scar tissue. This scar tissue can result in even more visual distortion and blurred vision.

  • Mild blurred vision
  • Slightly distorted vision (straight lines appear bent or wavy)
  • Some sensitivity to light and glare
  • Red-eye and/or swelling
  • Chronically irritated eyes

In its later stages, one tends to experience:

  • Increased blurred and distorted vision
  • Nearsightedness or irregular astigmatism
  • Inability to wear regular contact lenses

Keratoconus Treatments

There are several ways to treat this condition. When the symptoms are still mild, you can correct your vision using eyeglasses. As the condition progresses, there are several treatment options.

  • Scleral lenses. For improved visual acuity, gas permeable scleral lenses are usually the preferred treatment. Scleral lenses vault over the cornea, replacing its irregular shape with a smooth, uniform refracting surface that provides clarity and comfort. (more information below)
  • Custom soft contact lenses. These customized soft lenses are specially designed to correct mild-to-moderate keratoconus.
  • Piggyback contact lenses. For those with keratoconus, fitting a gas permeable (hard) contact lens over a cone-shaped cornea may at times prove uncomfortable. “Piggybacking” involves placing a soft contact lens over the eye and then placing a GP lens over the soft lens. This increases wearer comfort because the soft lens acts like a cushioning pad under the rigid GP lens.
  • Hybrid contact lenses. These lenses combine a highly oxygen-permeable rigid center with a soft peripheral “skirt”. Some hybrid lenses are specifically designed for keratoconus, with the central GP area of the lens vaulting over the cone-shaped cornea.
  • Intacs. This small curved device is surgically placed in your cornea to help flatten the corneal curvature and improve vision.
  • Corneal collagen cross-linking. Used together, special UV light and eye drops can strengthen the cornea, thus flattening your cornea and preventing further expansion.
  • Corneal transplant. As a last resort, you may be advised to undergo a corneal transplant, where all or part of your diseased cornea is replaced with healthy donor cornea tissue. Even after a transplant, however, you may still need to wear glasses or contact lenses for clear vision.
