A survey of wearers of low water content hydrogel contact lenses

Efron, Nathan & Brennan, Noel A. (1988) A survey of wearers of low water content hydrogel contact lenses. Clinical and Experimental Optometry, 71(3), pp. 86-90.


Poly-2-hydroxyethylmethacrylate (HEMA) remains the most widely used of all contact lens materials. To explore the application of HEMA in current contact lens practice, we conducted a survey of 104 wearers of HEMA contact lenses presenting consecutively to a large contact lens clinic. Significant differences were found between the in vivo water content of different lens types, indicating that certain differences exist between materials generally classified as 'HEMA'. Reporting of the symptom of 'dryness' was correlated with the measurement of a lower lens water content. The phenomenon of lens aging could not be explained by changes in lens water content.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
