Clasgen eye drops are a prescription-only medication used primarily to treat chronic dry eye disease, a condition also known as keratoconjunctivitis sicca. Its active ingredient, cyclosporine, acts as an immunosuppressant to address the underlying inflammation that often causes reduced tear production. Instead of merely providing temporary lubrication like over-the-counter artificial tears, Clasgen works to restore the eye's natural ability to produce tears over time.
The Primary Purpose of Clasgen Eye Drops
The main indication for Clasgen is the treatment of dry eye disease caused by chronic inflammation of the cornea and conjunctiva. Patients with this condition experience a persistent feeling of dryness and discomfort. Symptoms often include a gritty sensation, blurred vision, sensitivity to light, and redness. By targeting the root cause of the inflammation, Clasgen helps to calm the ocular surface and create a healthier environment for tear glands to function properly. This leads to a more stable tear film, which protects the corneal surface and improves overall eye comfort.
How Clasgen Works: The Role of Cyclosporine
Clasgen's effectiveness is due to its active ingredient, cyclosporine. Cyclosporine is classified as an immunomodulator, meaning it works by modulating the body's immune response. In the case of chronic dry eye, the immune system mistakenly targets the tear-producing glands, causing inflammation and reducing tear output. Cyclosporine specifically suppresses the activity of certain immune cells on the ocular surface, reducing inflammation and allowing the tear glands to recover and increase natural tear production.
Key Uses for Clasgen Eye Drops
Beyond treating general chronic dry eye syndrome, Clasgen is also used in other specific scenarios related to ocular surface health. Some of these applications include:
- Relieving Dry Eye Symptoms: It is used to alleviate common dry eye symptoms such as burning, itching, a foreign body sensation, and blurred vision.
- Supportive Treatment for Corneal Ulcers: It can be used as a supportive therapy for chronic corneal ulcers associated with severe dry eye disease.
- Treating Vernal Keratoconjunctivitis: Some ophthalmic cyclosporine drops are prescribed for this allergic eye condition.
- Managing Ocular Rosacea: Inflammation of the ocular surface linked to rosacea may also be treated with cyclosporine.
- Addressing Lacrimal Gland Dysfunction: Following surgery or radiotherapy, it can help manage dysfunction of the tear-producing lacrimal glands.
How to Use Clasgen Eye Drops Correctly
To ensure proper application and efficacy, follow these steps:
- Wash your hands thoroughly with soap and water before handling the drops.
- Use single-dose units: Clasgen is supplied in sterile, preservative-free, single-use droppers.
- Prepare the drop: Gently twist to open the single-dose unit.
- Administer the drop: Tilt your head back slightly and pull your lower eyelid down with your index finger to create a small pocket. Squeeze one drop into the pocket. Do not let the tip touch your eye or any other surface.
- Close the eye: Gently close your eye for a few seconds to allow the medication to spread. Applying gentle pressure to the inner corner of the eye can help prevent drainage.
- Discard: Throw away the single-dose unit immediately after use, even if there is remaining solution.
- Contact lenses: Remove contact lenses before use. You can reinsert them 15 minutes after instillation.
- Other eye drops: If using other eye drops, wait at least 15 minutes between applications.
Clasgen vs. Other Cyclosporine Eye Drops
Clasgen is one of several prescription eye drops containing cyclosporine. Others, like Restasis and Cequa, are also available for treating dry eye. The key difference often lies in the concentration of the active ingredient and formulation. It is important to consult your eye doctor to determine the most suitable option for your condition.

Potential Side Effects and Precautions
While generally well-tolerated, Clasgen may cause side effects, with a temporary burning sensation being the most common. Other potential side effects include:

Rarely, more serious side effects like a severe allergic reaction can occur. It is important to contact your doctor immediately if you experience hives, difficulty breathing, or swelling of the face, tongue, or throat.
Several precautions are necessary when using Clasgen. These include:
- Do not use this medication while wearing contact lenses.
- Inform your doctor if you are pregnant, planning to become pregnant, or breastfeeding.
- Always follow the prescribed dosage and instructions carefully.
- Do not allow the dropper tip to touch any surface to prevent contamination.
- Discard single-dose vials after each use.
Conclusion: Is Clasgen Right for You?
Clasgen eye drops are a targeted and effective treatment for chronic dry eye syndrome, particularly when inflammation is a key cause. By addressing the underlying immune-related inflammation, it helps to restore the eye's natural ability to produce tears and provides long-term relief from persistent symptoms. Unlike temporary solutions, Clasgen offers a proactive approach to managing the condition. However, because it is a prescription medication, a proper diagnosis from an eye care professional is necessary to ensure it is the right treatment for your specific situation. Discussing your symptoms and medical history with your doctor is the best way to determine if Clasgen is a suitable part of your dry eye management plan.
