Abstract Details

Purpose:

To analyze visual, refractive and topographic results after Ferrara-type intracorneal ring segments implantation (ICRS) for keratoconus treatment in patients under 18 years old.

Setting:

Department of Ophthalmology, Hospital de Braga, Portugal

Methods:

This multicenter retrospective study included under 18 years old keratoconus patients who had ICRS implantation at Hospital de Braga and at the Ophthalmology Department of Hospital CUF with a minimum follow-up of 36 months. Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), refraction, corneal topography, and corneal aberrometry, pachymetry map and slit-lamp microscopy were assessed before and after surgery at 1 day, 6,12, 24 and 36 months.

Results:

The study included 32 eyes of 24 patients. Mean UCVA improved from 0,18 ± 0,20 to 0,37 ± 0,32 (decimal scale) and BCVA improved from 0,45 ± 0,26 to 0,66 ± 0,33 at 36 months follow-up. Mean sphere and cylinder improved from - 2,81± 3,79 D to -0,39 ± 1,01 D and from 3,42 ± 2.13D to 1,88 ± 0.85 D at 36 months. At 6 months, mean K1, K2 and Kmax values decreased. Visual, refractive and topographic parameters were stable between 6, 12, 24 and 36 months, with no statistically significant differences during the follow-up.

Conclusions:

Implantations of ICRS is an effective, safe and stable treatment in patients under 18 years old, showing its potential to halt the disease progression even in the pediatric population.
