As optometrists, we spend a great deal of our time trying to keep our contact lens wearers happy and comfortable. No matter how much effort we put into this, preventing dropout is often a struggle. While there are many reasons for dropout, two of the most common are dry eye and allergic eye disease. When both are present, it creates a significant clinical challenge.
Influenced by clinical feedback that discomfort is the number one cause of dropout, the latest contact lenses have evolved significantly to improve ocular comfort. Researchers have been trying to improve comfort by increasing water content, decreasing the modulus, lowering contact angle hysteresis and adding surface coatings and plasma treatments. They are also unsure if lubricity is the ...
Whether you’re working with a first-time contact lens patient or an existing wearer who is having difficulties, you need to play every card you hold if you want to win them over to long-term lens wear. During the contact lens fitting process, the influence of case systems on comfort is often sidelined for a proper fit and correction, and with a 24% contact lens dropout rate directly due ...
It’s a fast-paced world, for sure. Health care is advancing daily, and we—and our patients—continue to enjoy the fruits of researchers’ labors. Recently, investigators presented a full year’s worth of findings at the Association for Research in Vision and Ophthalmology’s (ARVO) meeting, held in Baltimore. Don’t you ...
We love our contact lenses. They improve our vision and looks while also helping us win on the athletic field. But we also hate our contact lenses, especially when they cause ocular irritation. Successful contact lens wear is multifactorial, and one of the leading factors is lens wettability. Research shows a dysfunctional tear film is associated with complaints of ocular discomfort and ...
Assessing corneal shape and integrity can be tricky, but the right tools can make all the difference when diagnosing corneal disease.
This simple alternative provides added benefits.
Here’s an in-depth look at the wide range of options now available.
Understanding the history of corneal anomalies and where they occur are important steps in preventing long-term complications.
New colored contact lens modalities and expanded technologies offer opportunities for both patient care and practice growth.
Differentiating the various etiologies can be difficult, but with the right training and diagnostic tools, you can find the right diagnosis and manage the patient accordingly.
These practice pearls aid in myopia management, including avoiding onset and slowing progression in patients of all ages.
Don’t let misconceptions stop you from using this treatment modality that can provide a huge benefit to patients with myopia.
From infancy to adolescence, contact lenses prove a viable and beneficial treatment option for a range of conditions.
Steady growth in the prevalence of this deceptively simple condition will expose half the world’s population to visual impairment. Here’s what to expect and what we should do.
Toric lenses can expand myopia management to include patients with astigmatism.
Let’s gain some perspective on the components, modalities and methodology of dry eye.
The simplest option is often the best solution.
Fitting toric lenses has become increasingly straightforward and now presents a viable option for myriad contact lens wearers.
Irregular cornea patients in particular can enjoy the many benefits that accompany fitting scleral lenses.
To understand and treat this common lid condition, make sure you’re clear on its many different presentations.
Keep these conditions in mind to prevent or rectify potential obstacles to a successful fit.
Despite the procedure’s popularity, some issues still remain. How should you address them?
Does a relatively new phenomenon help explain contact lens discomfort?
