| ICR is the abbreviation
for "Intrastromal Corneal Ring". A synthetic ring consisting
of two segments is implanted in the stromal bed of the cornea.
Today, this method is used for nearsightedness of approximately -1
to -4 dpt. The astigmatism may not exceed -1 dpt.
The ICR (also named "KeraVision Ring" after its manufacturer)
is considered to be a corneal implant and represents one of the newest
developments in the area of refractive surgery. This procedure has been
used by experienced ophthalmologic surgeons in Germany since 1996.
The ICR did not prove to be effective and successful for the correction
of myopia. It is used for patients with rare corneal diseases only.
