Diagnosis and Treatment of Keratoconus

Keratoconus is caused by a thinning of the cornea, which transforms the surface of the eye from a round sphere to a cone shape. This affects the way that light enters the eye and can cause blurry or distorted vision. Although keratoconus usually progresses slowly, early detection is vital to ensuring the most effective, minimally invasive treatment options. Several of the doctors at Silicon Valley Eye Physicians have undergone extensive training and managed hundreds of keratoconus cases throughout their careers. Additionally, both offices in Sunnyvale and Santa Clara, CA, are equipped with advanced diagnostic technology and custom contact lens design and manufacturing equipment to help you receive treatment that addresses your unique needs. 

What Is Keratoconus? 

Keratoconus affects your cornea and is caused by a weakening of the collagen bonds that provide structure and stiffness to the corneal tissue. When these bonds weaken, the cornea can bulge outwards in a cone-like shape and cause vision issues including nearsightedness, blurred vision, and sensitivity to light. Although each patient experiences keratoconus for different reasons, certain factors may increase your risk including: 

  • Intense sun exposure 
  • Excessive rubbing and irritation 
  • Contact lenses that do not fit correctly
  • Enzyme imbalance 
  • Genetic disposition 

As the severity of keratoconus progresses, your vision usually becomes more blurry and distorted. Eventually, the shape of the cornea can make wearing contacts uncomfortable or impossible. 

We have managed hundreds of cases of patients who suffer from keratoconus and are equipped with the training and technology to create custom contact lenses.

Diagnosing Your Disorder 

Our doctors perform testing for keratoconus during your routine comprehensive eye exam. If it is determined that you have keratoconus, we will perform additional testing including cornea scanning. During scanning, we will check for scarring or irregular curvature of the cornea. If we detect keratoconus in one or both eyes, we will typically begin with conservative, non-surgical options before recommending other treatments. 

Treating Keratoconus 

Although keratoconus is a chronic condition, we can provide several conservative treatment options to restore function and comfort to your vision. 

Scleral Contact Lenses 

Currently considered the gold standard in the treatment of keratoconus, these lenses can provide extensive benefits for patients with keratoconus. In our experience, these lenses provide the best outcomes for patients with keratoconus. Scleral lenses cover a larger portion of the eye and can help you achieve long-lasting, sharper vision with a reduced risk of complications from contact lenses. 

Hybrid Lenses 

Hybrid lenses, also known as SynergEyes®, combine the comfort of a soft lens with the function of a hard lens. For patients who are not good candidates for scleral contact lenses, we may recommend hybrid lenses.
