What Is Keratoconus?

Keratoconus is a progressive disease that causes gradual thinning of the cornea (the clear window covering the eye). This degenerative condition leads to structural changes and weakening of the corneal tissue over time. Eventually, the normally round cornea deforms into a cone shape, which fails to properly refract light onto the retina. This causes impaired visual acuity and may continue to worsen over time as vision begins to appear distorted or blurry. In patients with keratoconus, the cornea has the potential to eventually undergo irreversible deterioration.

Board-certified ophthalmologist Dr. Ralph Chu is highly experienced in diagnosing and treating keratoconus. He offers some of the most advanced procedures available in the ophthalmic industry to prevent future vision loss and help patients gain clearer eyesight. Contact Chu Vision Institute in Bloomington, MN to schedule a comprehensive eye exam, and learn about cutting-edge treatments for keratoconus.


Keratoconus tends to develop in the teenage years or early 20s. Symptoms may progress slowly over time, which can make this corneal condition difficult to diagnose at first. In some cases, the onset can occur later in life. Keratoconus tends to go undiagnosed until obvious symptoms start to appear. The most common signs are:

  • Astigmatism
  • Sensitivity to light
  • Distorted or blurry vision
  • Progressively worsening far-away vision
  • Frequent eye prescription changes

Since the symptoms of keratoconus can present similarly to those of other ocular conditions, it's essential to have your eyes examined by an ophthalmology specialist.


Keratoconus is typically an inherited condition. However, it can also develop as a result of environmental factors, including excessive UV light exposure, an enzyme imbalance within the cornea, chronic eye rubbing, improperly fitted contact lenses, or corneal thinning following eye surgery. Dr. Chu recommends that everyone have regular comprehensive eye exams at least every other year to check for many eye diseases and complications, including keratoconus.

KERATOCONUS Treatment Options

Dr. Chu can provide a number of innovative treatment options for keratoconus, which are customizable based on the phase and severity of your disease. If you are in the early stages of keratoconus, we may give you a prescription for eyeglasses or contact lenses to manage your condition. In the later phases, a more advanced treatment may be needed. We offer corneal cross-linking, phototherapeutic keratectomy (PTK), and both partial- and full-thickness corneal transplants. When you visit our office for your initial consult, we will conduct a comprehensive eye exam and review your health history to determine the best treatment to improve your vision.

Keratoconus is Treatable

Although keratoconus can result in partial or total vision loss, it is possible to prevent or slow these symptoms by having the condition diagnosed and treated. Because it is a degenerative condition, it is important to have an eye exam as soon as you notice signs. Dr. Chu and the skilled team at Chu Vision Institute have years of experience helping keratoconus patients protect their sight and eye health. Contact us today to schedule an exam at our facility in Bloomington, MN.
