Understanding Keratoconus: Causes and Symptoms

Keratoconus is a rare condition affecting your cornea which is normally round and dome-like. However, individuals with keratoconus tend to have “cone-shaped” cornea resulting to distorted vision. Here at the Roholt Vision Institute, patients who suffer from keratoconus may make daily activities of living somewhat difficult such as reading, driving, typing on a computer, cooking, and watching television.

Although the main cause of keratoconus is unknown, it has been shown that the following factors may play a role:

  • genetics
  • history of eye injury or prolonged used of hard contact lenses
  • certain eye conditions such as retinopathy of prematurity, vernal keratoconjunctivitis, and retinitis pigmentosa
  • systemic diseases like Down syndrome

Symptoms of Keratoconus
The symptoms of keratoconus could be divided into two — early and late. Early symptoms include

  • blurring of vision
  • distortion of vision
  • mild irritation of the eye
  • increased sensitivity to light

On the other hand, progression of the condition could lead to the following:

  • increased blurring and distortion of vision
  • increased nearsightedness
  • frequent changes with eyeglass prescription
  • inability to wear contact lenses

At Roholt Vision we are back seeing patients at all of our locations.   You will notice less chairs in our waiting rooms and ask that all non-essential companions wait in their car.   We recommend that all patients wear a mask to their appointment.  We want you to know that upon arrival we will be asking you a series of COVID-19 screening questions and your temperature will be taken. 


As far as our staff, each staff member will have their temperature taken upon arrival to work. They will also be wearing masks, instructed on proper handwashing, and are asked not to report to work if they are not feeling well. All staff members have been informed and trained on our increased sanitizing protocol. 


We look forward to seeing you!
