Purpose: To evaluate outcome of visual acuity (VA), refractive predictability and refractive stability 1, 3 and 12 months after implantation of intra corneal ring segments (ICRS) for correction of low myopia. Methods: In a retrospective study, 25 eyes of 16 patients with low myopia (-1- -4D) implanted with ICRS were examined after 1 day, 1, 3 and 12 months. Visual acuity, refractive predictability and stability were evaluated. Results: The best corrected visual acuity (BCVA) of all patients were <= 1,0. At first post-operative day 80%, after 1 month 78% and 3 months 75% of patients had an uncorrected VA <= 0,5. After 1 year 100% of patients (N=6) the uncorrected VA were <=0,5. Between month 1 and 3, 18% of subjects had +1D change in refractive error. At 3 respective 12 months 100% of patients were within + 1D. Conclusions: Implantation of ICRS for correction of low myopia seems be offer a predictable and stable outcome.
