In-office measurement of soft contact lenses. 1977

J Chaston

The dimensions of soft contact lenses cannot be measured by methods used for hard lenses, so new techniques have had to be devised. This paper introduces standards and tolerances for the measurement of soft contact lenses. Previous methods of measuring these lenses are reviewed, and 2 new methods are described for measuring thickness and diameter. Instrument errors and the reliability of these methods are assessed.
