Experts debate corneal collagen cross-linking methods

SAN FRANCISCO — The best practices to follow during corneal collagen cross-linking have yet to be determined, but the procedure has numerous benefits, a panel of experts said here. “While there are controversies, all studies and early users agree that CXL halts the progression of ectatic disorders and usually causes some degree of regression of the disease,” John A. Hovanesian, MD, FACS, said during the Update on Corneal Collagen Cross-linking panel sponsored by the American Society of Cataract and Refractive Surgery’s cornea and refractive surgery committees during the ASCRS meeting.

Femtosecond laser-assisted cataract surgery not feasible in infants at present time, specialist says

BASSANO DEL GRAPPA, Italy — The use of femtosecond laser in congenital cataract surgery deserves consideration but is not feasible at the current stage of development of the technique, according to a pediatric ophthalmology specialist. “There is no reported experience in infants, but theoretically, the disadvantages would by far outweigh the potential advantages,” Paolo Nucci, MD, said at an ophthalmology meeting organized at the San Bassiano Hospital here.

IOL calculations in post-LASIK eyes pose numerous challenges

SAN FRANCISCO — Thorough assessment and patient counseling are critical to making accurate IOL power calculations in eyes that previously underwent myopic LASIK, a speaker said here.During Cornea Day, which preceded the American Society of Cataract and Refractive Surgery meeting, Sumit Garg, MD, explained the various factors that can complicate IOL calculations in post-LASIK eyes.
