Contact lenses fitted in 29 cases of unilateral keratoconus resulted in better distance and near visual acuity, a study found.

Keratoconic corneas showed significantly more posterior corneal aberrations than normal corneas.

A universal standard protocol for assessing corneal staining in soft contact lens wearers should be established, study authors said after retrospectively examining the records of 338 hydrogel contact lens wearers.

ATLANTA — Fitting penetrating keratoplasty patients for contact lenses early in the postoperative period helps them regain vision and may have a long-term benefit for corneal shaping, a surgeon said here.

LARGO, Fla. — Unilens Vision has launched the C-VUE Advanced Custom Toric lens, according to a company press release.

No clinically meaningful differences in axial length, corneal curvature or myopia were found between children wearing soft contact lenses and children wearing spectacles.

The time course for uptake and release was too fast for effective drug delivery when ciprofloxacin was tested for topical extended release from soft contact lens materials.

While contact lens wearers with dryness symptoms can experience significant increases in lid wiper epitheliopathy and lid parallel conjunctival folds, they do not appear to exhibit more corneal staining, bulbar hyperemia or decreased pre-lens tear break-up times, a study found.

A prospective, case-controlled study of contact lens users admitted to an eye hospital in London for microbial keratitis showed a greater risk of developing the infection among users of daily disposable contact lenses compared with planned replacement soft lenses.

Tisilfocon A polymer contact lens material can maintain acceptable corneal health and visual acuity for rehabilitation of patients with highly irregular or diseased corneas, a retrospective study found. The majority of failures were due to design and discomfort unrelated to the lens material.
