CLEAR - Contact lens technologies of the future.

Contact lenses in the future will likely have functions other than correction of refractive error. Lenses designed to control the development of myopia are already commercially available. Contact lenses as drug delivery devices and powered through advancements in nanotechnology will open up further opportunities for unique uses of contact lenses.

American Academy of Optometry Microbial Keratitis Think Tank.

Significance: Think Tank 2019 affirmed that the rate of infection associated with contact lenses has not changed in several decades. Also, there is a trend toward more serious infections associated with Acanthamoeba and fungi. The growing use of contact lenses in children demands our attention with surveillance and case-control studies.

The impact of silicone hydrogel materials on overnight corneal swelling.

Purpose: To identify the corneal swelling response associated with silicone hydrogel contact lens wear.

Methods: Twenty-five subjects were recruited to participate in this single-center, controlled, single-masked, clinical trial. The corneal swelling response was evaluated by central corneal pachymetry after overnight wear of balafilcon A, etafilcon A, lotrafilcon A, senofilcon A, and no lens wear.

An evaluation of 1-day disposable contact lens wear in a population of allergy sufferers.

Purpose: This was a multi-site, 128-subject, bilateral crossover study to evaluate subjective comfort and slit-lamp findings with 1-day disposable contact lenses in a population of allergy sufferers during periods when allergen levels were elevated.

Methods: The study involved 1-month of single-use daily wear with a 1-day disposable test lens (1. DAY ACUVUE Brand Contact Lenses, Johnson & Johnson Vision Care) and 1-month of daily wear with subjects' habitual lenses replaced to their usual replacement schedule.

Short-term physiologic response in neophyte subjects fitted with hydrogel and silicone hydrogel contact lenses.

Purpose: To investigate the short-term physiologic response to three soft lens materials with different oxygen permeability characteristics.

Methods: Forty-three neophytes were randomly prescribed Acuvue 2, Acuvue Advance (Johnson & Johnson Vision Care), or Focus Night & Day (CIBA Vision) for 4 weeks on a daily-wear basis. A further 19 subjects did not wear lenses (control).

Influence of replacement schedule and care regimen on patient comfort and satisfaction with daily wear frequent-replacement contact lenses.

Purpose: This study examines what effects replacement schedule and care regimen have on overall patient satisfaction with daily wear frequent-replacement contact lenses.

Methods: Over 3000 patients were recruited from 313 ophthalmologic practices in France to participate in a 1-month prospective observational clinical study. Subjects included 2108 experienced and 957 novice users of the predominantly prescribed soft contact lenses and care systems in France.
