Contact Lenses

The majority (91 percent) of astigmatic patients are willing to trial a daily disposable contact lens for astigmatism with a doctor’s recommendation, research shows.

Zeiss recently introduced Zeiss Officelens, a customized, task-specific lens that allows patients to choose the amount of working distance they need, from 3 to 14 feet, to help battle computer vision syndrome.

According to the survey, a majority of consumers admit to a number of behaviors that could lead to dirty lenses, and ultimately, discomfort or infection. For example, storing CLs in tap water rather than in disinfecting solution (35%) or failing to rinse lenses with disinfecting solution before placing them in their lens storage case (55%).

A coefficient of friction value on human corneal donor tissue has been measured for the first time, according to new research conducted by Johnson & Johnson Vision Care, Inc. and presented in a poster at the recent American Academy of Optometry meeting. The research also shows that while coefficient of friction is dependent on the type of buffer solution, it may not be dependent on donor age or on the time of death when measuring fresh corneal tissue.

The TFOS International Workshop on Contact Lens Discomfort report is available to help practitioners better understand the challenge with contact lens wear.

I used to take noncompliance personally. I was failing my patients as their eye doctor. After all, it’s my job to explain the risks of contact lens wear and care non-compliance, and if my patients weren’t complying then I must be doing a poor job of communicating those risks. One of the many points I learned: It’s not my fault!

Preventing CL dropouts can be a challenge with patients suffering from CLIDE. A number of factors, including the patient’s overall general health, the type of contact lens worn and solution interaction, among others, can influence the condition. Predicting which CL patients are more likely to develop dry eye helps you tailor management to the individual patient needs and set realistic patient goals for successful lens wear.

CooperVision adds additional myopic and hyperopic powers to its silicone hydrogel Biofinity line and adds -2.25 D to its Avaira cylinder availability.

While there are many factors involved, a number of individuals opt out of wearing their contact lenses every year. Randy Kojima, FAAO, a research scientist and clinical instructor at Pacific University College of Optometry, discusses how there could be a mechanical component involved.

In a study comparing extended wear and daily wear contact lenses, extended contact lens wear was associated with more inflammatory and infectious complications, says Loretta Szczotka-Flynn, OD, PhD, from Case Western Reserve University, Cleveland, OH, They appeared to have a greater frequency of lens bioburden and decreased frequency of lid bioburden, as compared to daily wear.

The future is here when it comes to innovations in ocular drug delivery, according to an expert panel, including such technologies as nanotechnology, contact lenses, and MIGS devices.

Daily disposable contact lenses provide a clean, deposit-free, sterile lens in a saline-based solution on a daily basis, so that each new lens is comfortable, safe, and convenient.

Dailies Total 1 water-gradient, daily disposable contact lenses are made using a new silicone hydrogel material (delefilcon A). The lens surface has a water content of more than 80%, and mimics the natural hydrophilic ocular surface. Studies have found that Dailies Total 1 lenses remained subjectively moist and comfortable throughout the day.

Alcon launches its new daily disposable contact lens to North American practitioners.

CooperVision’s app helps your patients stay in contact lens wear during allergy season.

Walmart and Sam's Club plan new initiatives in 2013, including a private-label contact lens brand, an online and phone contact lens program, and lower prices on contact lenses.

Alden Optical launches Alden On-Demand series, with the first a NovaKone training and certification

Nearly one-half of patients requiring vision correction are significantly astigmatic in at least one eye and could benefit from advances in toric contact lens technology, according to a study published in Eye & Contact Lens: Science and Clinical Practice.
