title: High degrees of astigmatism: are hydrogels the answer?
abstract: A bilateral compound hyperopic astigmat, with-the-rule, with incipient presbyopia and refractive amblyopia fitted with toric (custom) soft lenses in a monofit mode is described. Shortly after wearing the hydrogel toric lenses the patient developed a severe allergic reaction from a thimerosal based saline, which eventually resolved.
