  • Title: Part II. Clinical evaluation of toric hydrophilic contact lenses.
    Author: Remba MJ.
    Journal: J Am Optom Assoc; 1981 Mar; 52(3):211-21. PubMed ID: 7229238.
    Abstract:
    Five toric hydrogel contact lenses have been approved for marketing by the FDA and several more await final approval in the near future. Clinical use of these special design lenses for correction of astigmatism has increased during the past year, improvements in lens design and fabrication are taking place, but problems remain. Analysis of the reasons for fitting failures show that lens quality and axis mislocation are the primary causes of lens performance failures.
