Abstract Details

Purpose:

To analyze the long-term visual, refractive and topographic stability of intracorneal ring segments (ICRS) implantation in patients with keratoconus.

Setting:

Vissum Corporaci├│n Oftalmol├│gica. Alicante, Spain

Methods:

Retrospective, comparative, clinical study including 69 keratoconic eyes divided in two grups: group a): stable cases, patients with no significant changes in visual, refractive and topographic variables during the 12 months previous to the surgery; and group b): progressive cases, patients with an increase in at least: 1 line in the corrected vision (CDVA), 2 diopters (D) in the spherical equivalent (SE) or 1 D in the mean keratometry (KM), during the 12 months previous to ICRS (Keraring and Intacs) implantation. The visual, refractive and topographic changes were evaluated during a period of 5 years.

Results:

A significantly improvement of CDVA, SE and KM were found after 6 months in both groups (p<0.05). In group a, five years after the surgical procedure these parameters remained unchanged (p= 0.31). A slight regression of 0.97 D was observed in KM between 6 months and 5 years. In group b, a worsening of the visual and refractive variables was observed during the follow-up. A regression of 3,36 D was found in the KM when comparing the results of six months and the last visit at five years.

Conclusions:

ICRS implantation provided long term improvement on the visual, refractive and topographic status in patients with stable keratoconus. Nevertheless, this procedure does not have a significant influence in those cases with progressive form of the disease.

Financial Interest:

NONE
