AB The objective of this work was to evaluate the potential use of less stiff materials based on acrylic copolymersof methyl methacrylate/2-ethylhexyl acrylate (MMA/EHA) as devices to correct, stabilize andimprove the effect of poly(methyl methacrylate) (PMMA) intracorneal ring segments. MMA/EHA andPMMA intracorneal ring segments were surgically implanted in the corneas of Lohmann Classic hens.The effects of the intracorneal ring segments were assessed by optical measurements and corneal tolerancewas evaluated through biomicroscopic examination over a 90-day observation period and by conventionalhistology. The experimental results demonstrated that the intracorneal ring segments madeof MMA/EHA copolymers provided a significant change in the corneal curvature and an improvedin vivo response compared to those obtained for PMMA rings, which was attributed to the higher flexibilityof the copolymeric materials, indicating that these systems might be considered suitable as analternative to those currently used, for application in clinical practice.
