Refractive error maps: A predictive tool for refractive error progression. [PDF]
Ophthalmic Physiol OptAbstractPurposeTo investigate the influence of axial length on different ocular parameters and create a predictive tool for refractive error progression.MethodsTwo eye models were used to simulate refractive errors, namely the Liou–Brennan and the Goncharov–Dainty. Both models were simulated using Zemax OpticStudio.
