Keratoconus, pronounced KEHR-uh-toh-KOH-nus, is an uncommon condition in which a normally round, dome-like cornea becomes thin and develops a cone-like bulge. Keratoconus can make some activities difficult such as driving, typing on a computer, watching television or reading.

Keratoconus usually affects both eyes. Symptoms usually start to occur in people who are in their late teens and early twenties and may include:
  • Mild blurring of vision
  • Slight distortion of vision
  • Increased sensitivity to light
  • Glare
  • Mild eye irritation
The rate of progression varies. Keratoconus will often progress slowly for 10 to 20 years and then stop.
As the condition progresses, most common symptoms include:
  • Increased blurring and distortion of vision
  • Increased near-sighted or astigmatism
  • Frequent eye prescription changes
  • Inability to wear contact lens

The cause of keratoconus is still not known. Some researchers believe that genetics play a role. An estimated 10% of people with keratoconus also have family members with the condition

Corneal Cross-Linking
Dr. Koreishi and Dr. Ple-plakon are proud to offer Corneal Cross-Linking at Cornea Consultants of Texas! The only FDA-approved cross-linking device, Avedro’s KXL system, will help us effectively treat progressive keratoconus and corneal ectasia here in Tarrant County! This exciting treatment option will allow patients with keratoconus or corneal ectasia to stop the progression of their disease and work toward improvement in corneal shape and vision. We hope to facilitate early detection of patients with keratoconus and increase awareness of the importance of early monitoring and treatment.

  • You should refrain from rubbing your eyes. This can aggravate the cornea tissue and make symptoms worse.
  • During the early stages, vision can be corrected with eyeglasses. As the condition progresses, Rigid Gas Permeable contact may be worn to correct distorted vision.
  • Corneal Cross-Linking (CXL) is a newer, recently FDA-approved procedure that will allow patients with keratoconus or corneal ectasia to stop the progression of their disease.  It is an office-based procedure that involves exposure of the cornea to riboflavin eye drops and a specific ultraviolet light. The CXL procedure creates more bonds within the collagen fibers, making the cornea stronger and more stable.
When good vision is no longer possible with contact lenses or glasses, a surgical procedure may be recommended.
  • INTACS corneal ring segments can help reshape the cornea to allow better contact lens fitting and improved functional vision.  This surgical procedure can help patients avoid a cornea transplant. 
  • Corneal transplant is only necessary in about 10-20% of patients with keratoconus. During a corneal transplant, the diseased cornea from the eye is replaced with a healthy donor cornea. Of all conditions requiring corneal transplants, keratonconus has the best prognosis for success and clear vision.

As cornea specialists in DFW, Dallas-Fort Worth, Dr. Koreishi and Dr. Ple-plakon strive to provide the best cornea care, availability, and patient education. Now open Plano Cornea.
