Who learns preventive health care information from where: cross-channel and repertoire comparisons.

We studied from which information channels individuals reported learning the most information about preventive health care, how those channels correlated with one another, and how well they were predicted by demographics and health orientations. A probability sample of 1,963 adults from 8 midwestern communities were interviewed from late 1994 to early 1995. Respondents reported learning different amounts of preventive health information from different channels, and a mix in levels of learning was found across channels. Television news and information rated unexpectedly high across the population studied. An exploratory factor analysis indicated a clear grouping or repertoire consisting of television channels, and for magazines and newspapers, but also a distinct personal media repertoire involving a mix of health professionals, family and friends, books, educational materials, and computers. Demographics did better at predicting learning from traditional print media, but personal health orientations were more effective predictors of personal media; television was less well predicted by either.

Hard contact lens corrections in aphakia.

Hard contact lens correction of aphakia is best performed with a single cut lens by a trial lens fitting. Lenticular design may be necessary. Continuous wear over age 70 may be necessary to achieve success and acceptance in more than 30% of aphakic wearers. Soft lenses are usually not practical in the author's experience. The increased use of intraocular lenses is decreasing the need for aphakic contact lenses. Merits of the hard contact lens in aphakia are discussed as a practical approach to the correction of vision by the ophthalmologist, and indications for single cut lenses and lenticular design are outlined.
