OBJECTIVES: To review and summarize relevant studies on combined use of corneal crosslinking and intracorneal ring segments (ICRS) for the treatment of corneal ectasia.
METHODS: A literature search was performed using the key words "corneal collagen cross-linking" and "intra-corneal ring segments."
RESULTS: Crosslinking is a well-accepted treatment option for corneal ectasia and can be combined with corneal ICRS insertion as needed. The advent of crosslinking has dramatically reduced the number of corneal transplants performed for patients with keratoconus or postrefractive ectasia. Intracorneal ring segments, although flatten the corneal surface, do not prevent the progression of corneal ectasia. This is why the combination of crosslinking and ICRS is potentially synergistic. Previous studies reported that combining these two complementary interventions has been shown to be safe and effective.
CONCLUSIONS: The effects of ICRS are enhanced and stabilized by crosslinking, but the ideal combined technique is not known at present.
