During the study period, 14.6% of eyes lost best-corrected scleral lens visual acuity, and all were due to keratoconus progression. “The results are consistent with other studies which show scleral lenses are overwhelmingly safe and effective at improving vision with a low frequency of adverse events,” Dr. Fuller says.
