Toric and toric multifocal IOLs in meridional amblyopia

摘要

正Dear Sir,M eridional amblyopia is sometimes put forward as a reason for not implanting Toric intraocular lenses(IOLs).It has been noted that patients with high levels of childhood astigmatism(3 DC)can develop persistent orientation-dependent visual deficits despite optical correction.Studies by Mitchell et al[1]demonstrated that meridional visual deprivation during the critical period of visual development results in permanently reduced response to stimuli in those orientations.This phenomenon was termed
