The authors report visual and topographic outcomes of intracorneal ring segment (ICRS) implantation alone or in combination with corneal cross linking (CXL) and long-term results in halting keratoconus in paediatric patients. This study was a retrospective design including 19 patients (26 eyes) aged <18 years and with two-year follow-up. Average age was 16.5 ±1.8 years (12-18); 16 male patients. Fifteen had allergic conjunctivitis, seven had bilateral ICRS implantation and 12 had unilateral ICRS. Preop uncorrected visual acuity (UCVA) median was 0.90 logMAR and best corrected (BCVA) median was 0.43 logMAR. Postop, UCVA was 0.54 logMAR and BCVA was 0.30 logMAR. Preop median refraction was -4.00DS and -5.75DC reducing to postop median of -2.00DS and -3.00DC. Preop maximal keratometry median was 54.40D reducing to postop median 49.80D. The authors found the ICRS implantation procedure, either alone or in combination with CXL resulted in visual improvements which were maintained over follow-up, with the ability to delay or prevent corneal transplantation.
