Keratoconus and Spectacles

Keratoconus and Spectacles

Patients with Keratoconus can often just not get spectacles or contact lenses that they can see clearly with.  

Higher-order aberrations (HOAs), which cannot be corrected by spectacles, are more subtle and complex refractive errors than near-sightedness, farsightedness and astigmatism. These optical and anatomical irregularities can cause difficulty seeing at night, glare, halos, blurring, starburst patterns, distorted images or double vision. 

Speciality contact lenses can effectively neutralize many of these induced aberrations by masking the irregularities on the front part of the cornea. There are different lens options like speciality soft, corneal gas permeable lenses, piggyback, hybrid and scleral lenses. Your Optometrist will choose a lens that will work for you based on the severity of your keratoconus. 

In the next few posts we will be discussing the surgical options for keratoconus patients and the possibility of clear spectacle & contact lens free vision.
