The role of RGPs in modern practice
Efron, Nathan (2010) The role of RGPs in modern practice. Contact Lens & Anterior Eye, 33(6), p. 260.
Has the 1998 prediction of a well-known contact lens researcher – that rigid contact lenses will be obsolete by the year 2010 – come to fruition? This Eulogy to RGPs will demonstrate why it has. A recent survey of international contact lens prescribing trends shows that rigid lenses constituted less than 5% of all contact lenses prescribed in 16 out of 27 nations surveyed. This compares with rigid lenses representing 100% of all lenses prescribed 1965 and about 40% in 1990). With the wide range of sophisticated soft lens materials available today, including super-permeable silicone hydrogels, and designs capable of correcting astigmatism and presbyopia, there is now no need to fit cosmetic patients with rigid lenses, with the associated intractable problems of rigid lens-induced ptosis, 3 and 9 o’clock, staining, lens binding, corneal warpage and adaptation discomfort. Orthokeratology is largely a fringe application of marginal efficacy, and the notion that rigid lenses arrest myopia progression is flawed. That last bastion of rigid lens practice – fitting patients with severely distorted corneas as in keratoconus – is about to crumble in view of a number of demonstrations by independent research groups of the efficacy of custom-designed wavefront-corrected soft contact lenses for the correction of keratoconus. It is concluded that rigid contact lenses now have no place in modern contact lens practice.
Impact and interest:
Citation counts are sourced monthly from and 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.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
