ICL™ for Keratoconus

Have you been turned away from LASIK or PRK because the doctor diagnosed you with keratoconus? Well that does not mean that you can never be free of contacts or glasses. You may still be suitable for Visian Implantable Contact Lens (Visian ICL™), a reversible vision correction option that keeps your cornea pristine.

What is Keratoconus?

Keratoconus is a progressive disorder that is characterized by cone-shaped outward bulging and thinning of the cornea, leading to distorted vision in relation to asymmetrical irregular astigmatism where the smooth surface of the cornea becomes slightly wavy and myopia that develops when the front of the cornea expands.

What are the symptoms?

  • Sudden change of vision or double vision in just one eye
  • Haloes around bright lights
  • Ghosting of images

How is Keratoconus Treated?

The treatment for keratoconus may vary depending on the stage of the disease, but rigid gas-permeable (RGP) contact lenses are often selected as a first choice to help mask the underlying irregular cornea. However, contact lens intolerance occurs in some eyes because of the compromised cornea or complications due to allergic conjunctivitis.

In such cases, patients may consider surgical treatments such as corneal transplant, intrastromal corneal ring segments and the corneal collagen cross-linking for treatment of the corneal irregularities. As for the short-sightedness caused by keratoconus, you may consider phakic intraocular lens implantation, which is the Visian Implantable Contact Lens (Visian ICL™).

Visian ICL™, a posterior chamber phakic intraocular lens that has been reported to be the premium vision correction surgery for moderate to high refractive error, may therefore be an option for patients with stable keratoconus. One such successful case was the Visian ICL™ implanted in Steven Holcomb, a bob sled pilot from team USA. Due to keratoconus, Holcomb’s vision was once as bad as 20/1000. His vision improved to almost 20/20 after surgery, allowing him to see things on tracks that he never knew were there before.

Why is LASIK not for you?
Procedures such as LASIK or PRK can be very dangerous for even a small degree of keratoconus because both surgeries remove tissue from the cornea in order to reshape it to the desired curvature. This will further weaken the structural integrity of the cornea and worsen the progression of keratoconus.
