Researchers say scleral contacts are well accepted by keratoconic patients

Researchers reported that patients with keratoconus experience less dryness with scleral lenses, but slightly more than half experienced midday fogging, according to a recent study.
Twenty-four patients with keratoconus completed a survey and a dry eye questionnaire, contact lens history, and comfort and preference survey. The survey also covered patient feedback on vision, dryness and midday foggy vision.
The cohort was mainly dry eye suspects but contained individuals with either normal or significantly dry eye scores, according to the dry eye questionnaire.
Previous contact lens experience included soft, piggy-back, and hybrid lenses but was most often corneal gas permeable, according to researchers.
When compared to other contact lens modalities, patients overwhelmingly preferred the comfort and vision with scleral contact lenses. In addition, keratoconus patients also experienced less dryness with the scleral lenses, according to the study.
The researchers subjectively confirmed previous research on superior vision through a scleral contact lens, according to the study.
“It seems the good vision and comfort achieved with the scleral contact lenses permitted the wearing time to be expanded...it may be argued that the scleral contact lenses should be tried at an earlier stage and possibly be the first rigid lens prescribed for keratoconus cases,” the researchers said.
They concluded that patients with dry eye may benefit from the protective coverage of the ocular surface provided by a 17.0 mm to 18.2 mm scleral contact lens. – by Abigail Sutton
