You may have heard of Tangible® Hydra-PEG® and may be wondering if it’s right for you, or appropriate for patients with certain conditions.
Tangible Hydra-PEG has demonstrated that it can:
- Increase wettability
- Increase comfort through end of day
- Reduce deposits on lenses
- Reduce fogging of lenses
While Tangible Hydra-PEG can be applied to any custom contact lens, these benefits may be particularly appropriate for certain patients who struggle with the comfort and clarity of their lenses, including those with dry eyes (not only Dry Eye disease), heavy depositors, scleral lens wearers, corneal lens wearers, and other patients with chronic comfort problems.
Dry Eye Sufferers Who Wear Custom Lenses
Millions of Americans suffer from dry eyes, a condition where there is a chronic lack of sufficient lubrication and moisture on the surface of the eye. Patients may be clinically diagnosed with Dry Eye Disease, or may experience dry eyes when wearing contact lenses. Some doctors prescribe scleral lenses to treat dry eye, as the design of these lenses traps tears under the lens and keeps them on the eye.
Symptoms when wearing contact lenses can include:
- Eye strain
Contact lens material can actually disrupt the eye’s tear film, reducing wetting and increasing feelings of dryness in the eye. There are also many different causes of dry eyes, that range from eye diseases such as Sjogren’s Syndrome, to use of certain medications that dry out the eyes, to the type of contact lens used, to excessive computer or mobile device time.
A patient is referred to as a “heavy depositor” when the chemistry of their tears results in high amounts of proteins building up on the contact lens surface on a daily basis. This can make the surface of the lenses rough and makes it difficult for the eyelid to move smoothly over the lens, causing scratchiness, itchiness and discomfort. Over time, as deposits accumulate on the lens, they can make the lens surface look “dirty” and can reduce the clarity of vision through the lens.
Patients with Scleral Fogging
Scleral lenses are growing in popularity today. They are prescribed for patients with certain complex ocular surface diseases, such as keratoconus and irregular corneas, as well as those with dry eyes.
While effective in correcting vision, scleral lenses are prone to midday fogging, which blurs vision and can create significant inconvenience for the patient. Addressing fogging involves the patient removing their lenses for cleanings throughout the day, which requires patients to carry eye care products with them wherever they go.
Patients Adapting to Corneal Lenses
A corneal lens sits directly on the cornea, which can be sensitive, and patients new to corneal lenses may feel discomfort and experience difficulty in the adaptation phase.
Patients with Comfort Issues
Custom lenses are excellent at correcting vision, but they are made of rigid – or hard – material. The properties of these rigid materials can cause the tear film to break up prematurely, which can lead to discomfort.
Custom lens patients may need to clean their lenses midday and frequently use rewetting drops to increase comfort throughout the day. This can be not only uncomfortable, but also inconvenient.
Tangible Hydra-PEG Can Help!
For all of these patients, Tangible Hydra-PEG can help improve their custom lens wearing experience.
