Abstract Details

Purpose:

To analyze if Intracorneal Ring Segment (ICRS) implantations can stop the progression of keratoconus in young (under 30 years old) and keratoconic patients after a long follow-up of 5 years.

Setting:

VISSUM Corporacion

Methods:

To analyze if Intracorneal Ring Segment (ICRS) implantations can stop the progression of keratoconus in young (under 30 years old) and keratoconic patients after a long follow-up of 5 years.

Results:

Significantly higher values of cylinder, corneal dioptric power in the flattest meridian (K1), corneal dioptric power in the steepest meridian (K2), and mean corneal power (mean K) were found and confirmed the keratoconus progression before surgery (p ? 0.01). The differences induced after 6 months of surgery in cylinder, K1, K2 and mean K were statistically significant (p ? 0.01) compared with the evolution changes before surgery. Although there was a long-term improvement in the visual, refractive, topographic and aberrometric data, the difference was not statistically significant when a comparison was made between the induced changes preoperatively and the difference between 6 months and 5 years (p > 0.01).

Conclusions:

The ICRS provided a significantly short-term improvement in visual, refractive and topographic parameters. Even when we observed that there were no statistical significants changes between 6 months and 5 years, there was a clinical relevant regression that showed that the ICRS may not be able to halt the KC progression.
