Artificial Tears — which drop is right for you?

Artificial tears may be used to treat dry eyes, since they contribute to the preservation of moisture on the surface of the eye. These eyedrops may be used to treat dry eyes caused by age, certain drugs, eye surgery, or environmental factors such as smoke or wind. Dry eyes are a common symptom of ocular surface disease, leading to vision loss.

Ingredients that are helpful

Hyaluronate acid

Hyaluronate is a sticky, slippery fluid that your body naturally creates. Scientists have discovered hyaluronic acid throughout the body, including in the eyes, joints, and skin. Certain species of bacteria are fermented to create hyaluronic acid.

Hyaluronic acid is entirely safe to use. Hyaluronic acid reactions or side effects are uncommon, and it is safe to use if you are pregnant or breastfeeding. Side effects are possible with products that mix hyaluronic acid with other drugs or substances. You must inform your healthcare practitioner about any drugs you take, including supplements and vitamins. They can assist you in better understanding any possible issues.


Trehalose is an innovative medication used to treat dry eye in other parts of the world; it is now being launched in the United States. It is a naturally occurring alpha-linked disaccharide produced when two units of alpha-glucose are bonded together by an alpha, alpha-1, 1-glucoside bond.

Trehalose is a bioprotectant and an osmoprotectant, and it is found in high concentrations in the natural world. By bolstering cell membranes and inhibiting the denaturation of proteins in the absence of water, it shields corneal cells from drying out.


Therapy for the eyes that does not include any preservatives is a tried-and-true method that has been shown to enhance patient outcomes and alleviate the symptoms of eye illness. Benzalkonium chloride is a common eyedrop preservative that can cause further irritation to the eyes. Patients who converted to BAK-free preparations reported a considerable drop in the usage of lubricants, according to research (P 0.001)1, and this finding was statistically significant.

In another investigation, corneal indications were shown to occur substantially more often in the group that received the preservative (P 0.0001) than in the group that did not. These indications include pain or discomfort after instillation (48% vs. 19%), the sense of a foreign body (42% against 15%), stinging or burning (48% versus 20%), and the sensation of dry eye (35% versus 16%).


Around a third of all medicinal products given as eye drops in the European Union (EU) contain phosphate, typically as part of a buffer system (a means of preventing the eye drop solution from being too acidic or too alkaline, which can irritate). Phosphates are substances that are commonly used in eye medicines.

Phosphates are rarely a component of the active ingredient, or present in the solution for reasons other than those previously stated. There were reports of people using eye drops that included phosphate when they acquired corneal calcification, and there was worry that the phosphate in the eye drops might be the cause of the issue in these patients.

Phosphate binds to dissolved calcium, so it was hypothesized that the calcium deposits in the eye might result from the phosphate in the eye drop adhering to the calcium in the ocular fluids, resulting in the formation of calcium phosphate deposits.

Contact Lens Compatible

Some people who wear glasses or have tried contact lenses in the past but stopped using them believe that they cannot use contact lenses because the information they have access to is no longer accurate.

The materials used for contact lenses have undergone significant advancements over the past few years. Computer-aided software has made it possible to manufacture prescriptions and designs that were previously unachievable.

These advancements have made it possible to manufacture lenses for high levels of astigmatism, multifocal designs for those requiring reading glasses, and complex structures made to order. Unlike us, not all opticians have access to every lens design, since some opticians only have a restricted selection of contact lens providers. Interested in trying or re-trying contact lenses?

Thealoz Duo

Because it does not include preservatives, Thealoz Duo can maintain excellent tolerance levels in the eye. It is safe for contact lens users who wear any type of contact lens, and it delivers instant comfort that continues throughout the day.

The primary components are sodium hyaluronate, a polysaccharide that is naturally present in the eye, and trehalose, a disaccharide found in many different plants and animals.

Trehalose is an antioxidant that also moisturizes and protects the body (specifically by maintaining the integrity of cell membranes by inhibiting the oxidation of proteins and the hydrolysis of lipids). Want to get the full benefits of the product? Visit our clinic to grab your bottle!
