What is Intrastromal Corneal Ring Segments (ICRS)?

Corneal thinning disorders often lead to protrusion, irregular astigmatism, and even perforation. Keratoconus, PMD (Pellucid Marginal Degeneration), and Keratoglobus do not have a known cause. However, corneal ectasia can also be acquired after the LASIK (Laser Assisted In Situ Keratomileusis) procedure. Corneal ectatic disease may impair vision which can be restored by optical means such as glasses, soft, or rigid gas permeable contact lenses. However, severe cases may require correction or restoration of tectonic integrity of the cornea by surgical means. Previously, PKP (Penetrating Keratoplasty) was the treatment of choice. Although PKP can be very successful in this subset of patients, limitations of PKP can include high post-op cylinder, side effects from chronic topical steroids, corneal rejection, and recurrence of keratoconus in the donor cornea. Intracorneal ring segments are a new modality in the treatment of corneal ectactic disorders.
