Patients with thin corneas as the result of keratoconus, ectasia following LASIK, or pellucid marginal degeneration can safely undergo epithelial-on collagen crosslinking with pulsed UV light and achieve visual benefits from the procedure.
The promise of simple, objective, single instrument-based screening for highly asymmetric keratoconus in patients considering LASIK is still more of an idea than reality. Multiple metrics can identify early keratoconus in a minority of affected eyes, but none of the metrics consistently identify early corneal abnormalities and none of the metrics identify the same eyes as being at elevated risk for ectatic disease.
Five-year results from a study of the Boston keratoprosthesis type 1 implant suggest that frozen and fresh corneal donors offer similar clinical outcomes—with no significant differences in device retention, visual rehabilitation or complication rates.
In order to avoid a public health crisis and keep up with increasing vision loss among the aging baby-boomer generation, correctable vision impairments must be eliminated by 2030, according to a report issued by the National Academies of Sciences, Engineering, and Medicine (NASEM).
Ben Gaddie, OD, FAAO, Optometry Times Editorial Advisory Board member, noted several specific areas that were advancing to give ODs better data and better control over patient health outcomes, including:
• Corneal mechanics
• 24-hour IOP monitoring
• New glaucoma drugs and drug delivery systems
• Advancements in OCT imaging
