Multicentre comparative clinical evaluation of daily care solutions for rigid gas-permeable contact lenses.

Results of a multicentre, controlled, comparative study of two daily care regimens for rigid gas-permeable contact lenses are described. Whereas both regimens were generally effective and safe for the 69 patients wearing the Boston Lens, the Barnes-Hind regimen showed clinically and statistically significant advantages over the Boston Lens regimen: the proportions of patients in the Barnes-Hind group with corneal staining or palpebral conjunctival injection were reduced during the study and were lower on several occasions than the proportions of the Boston group.
