What Cyanoacrylate Tissue Adhesive is used for

Cyanoacrylate Tissue Adhesive is a special medical glue used in ophthalmology (eye care) to treat specific conditions affecting the cornea. The cornea is the transparent, outermost layer of your eye that helps focus light. When the cornea gets damaged, it can sometimes develop a hole or become dangerously thin. This medicine acts as a temporary patch to protect your eye.

Corneal perforation (a small hole in the cornea)
Descemetocele (severe thinning of the cornea that is about to perforate)

In simpler terms, if there’s a small leak or a very weak spot in the front window of your eye, this adhesive acts like a quick, strong plug to prevent further damage and protect the eye while preparing for a more permanent solution.

How it works

Cyanoacrylate Tissue Adhesive works by forming a strong, immediate bond when applied to the surface of the eye. Think of it like a very strong, medical-grade superglue. When there is a small hole or a very thin area in your cornea (the clear front part of your eye), the specialist carefully applies a tiny amount of this adhesive to the affected spot. It quickly hardens and creates a physical barrier, effectively plugging the small corneal perforation or reinforcing the weakened area. This prevents fluids from leaking out of the eye and protects the delicate inner structures from infection or further damage. It acts as a tectonic glue, meaning it helps to structurally support and seal the tissue. This immediate sealing action is crucial in preventing complications and stabilising the eye, buying valuable time until a more definitive surgical repair can be performed.

How it’s used

Cyanoacrylate Tissue Adhesive is not a medicine you would ever apply yourself at home. It is a specialised medical procedure performed only by a qualified ophthalmologist (eye specialist) in a hospital or clinic setting. The application of this adhesive requires precision and sterile conditions.

Here’s a general idea of how it is typically used:

In a Clinic or Theatre: The ophthalmologist will apply the adhesive directly to the affected area of your cornea. This is usually done under a microscope to ensure accuracy.
With a Bandage Lens: After the adhesive is applied, it is very common for the doctor to place a special soft contact lens, called a bandage lens, over your eye. This lens acts like a protective cover, helping to keep the adhesive in place, promoting comfort, and aiding in the healing process.
Not for Self-Use: It is critical to understand that this is a hospital-use only product. You will not be given this adhesive to take home or apply yourself. The doctor will manage its application and subsequent care.
Follow-up Care: After the application, your doctor will provide specific instructions for follow-up appointments. It is very important to attend these appointments so the doctor can monitor your eye’s healing and plan for any further treatment.

Always follow your ophthalmologist’s exact instructions.

Good to know

Prescription eye medicine — use only as directed by a qualified ophthalmologist.

Precautions & side effects

While Cyanoacrylate Tissue Adhesive is a valuable tool for treating serious eye conditions, it is important to understand its role and any precautions associated with its use:

Temporising Measure: It is crucial to remember that this adhesive is generally a ‘temporising measure’. This means it provides a temporary solution to stabilise the eye and prevent further damage. It is usually applied to buy time before a more definitive surgical repair can be performed. It is not typically a permanent cure on its own.
Hospital Use Only: This is a prescription eye medicine that is strictly for hospital use. It must only be applied by a qualified ophthalmologist in a clinical or surgical setting. Never attempt to self-medicate or reuse an old prescription for this product.
Professional Guidance: Always use this medicine only as directed by your ophthalmologist. This page provides general information and is not a substitute for professional medical advice, diagnosis, or a prescription. Your doctor will assess your specific condition and determine the appropriate course of treatment.
Not for Self-Application: This adhesive is never for self-use. Its application requires specialised skills and equipment.

Understanding Corneal Perforation and Descemetocele

Your eye is an amazing and complex organ, and the cornea plays a vital role in your vision. The cornea is the clear, dome-shaped front surface of your eye, much like a transparent window. It helps to focus light onto the retina at the back of your eye, allowing you to see clearly. Because it’s on the front, it’s also exposed to the environment and can sometimes get injured or develop problems.

A ‘corneal perforation’ means there’s a small hole in this clear front window of your eye. This can happen due to various reasons, such as severe infections, injuries, or certain eye conditions that cause the cornea to thin out. A hole in the cornea is a serious condition because it can allow fluid to leak out of the eye and germs to get in, potentially leading to severe infection and vision loss. It’s like having a puncture in a tyre – it needs to be sealed quickly.

A ‘descemetocele’ is an even more critical stage of corneal thinning. It means the cornea has become so thin that only its innermost layer (Descemet’s membrane) is left, and it’s bulging outwards. This is a very dangerous situation because the eye is on the verge of perforating (developing a hole). Both corneal perforation and descemetocele require urgent medical attention from an eye specialist.

Cyanoacrylate Tissue Adhesive is used in these critical situations to provide an immediate, temporary seal or reinforcement, protecting the eye from further damage while the doctors plan for a more permanent solution, which often involves surgery.

General Eye Care and Hygiene

Maintaining good eye hygiene is essential for everyone, especially if you have an eye condition or are recovering from treatment. Here are some general tips:

Hand Hygiene: Always wash your hands thoroughly with soap and water before touching your eyes or applying any eye drops or ointments (though remember, Cyanoacrylate Tissue Adhesive is applied by a doctor, not by you). Clean hands help prevent the transfer of germs to your eyes.
Avoid Rubbing Your Eyes: Try to avoid rubbing your eyes, especially if you have an existing eye condition or have just had treatment. Rubbing can irritate your eyes, dislodge a bandage lens, or even introduce infection.
Cleanliness of Eye Products: If you are using other eye drops or ointments prescribed by your doctor, ensure the tip of the bottle or tube does not touch your eye or any other surface. This prevents contamination of the medicine. Always replace the cap tightly after use.
Follow Doctor’s Instructions: Adhere strictly to all instructions given by your ophthalmologist regarding any other medications, follow-up appointments, and activities to avoid.
Protect Your Eyes: If advised by your doctor, wear protective eyewear, especially in dusty environments or during activities that might pose a risk to your eyes.

When to Seek Medical Help

After receiving treatment with Cyanoacrylate Tissue Adhesive, or for any eye concern, it’s vital to know when to contact your eye specialist immediately. Your doctor will give you specific instructions, but generally, you should seek urgent medical attention if you experience any of the following:

Sudden Decrease in Vision: Any sudden or significant change in your ability to see.
Increased Pain: If your eye pain worsens significantly or becomes severe.
Redness or Swelling: If the redness in your eye increases, or if there is new or worsening swelling around your eye.
Discharge: Any new or increased discharge (pus or watery fluid) from your eye.
Light Sensitivity: Increased sensitivity to light (photophobia).
New Floaters or Flashes: Seeing new spots or cobweb-like shapes floating in your vision, or experiencing flashes of light.
Loss of Bandage Lens: If you were given a bandage contact lens and it falls out or feels uncomfortable, contact your doctor immediately. Do not try to reinsert it yourself.
Any Unusual Symptoms: If you notice any other symptoms that worry you or seem unusual after your treatment.

Remember, your ophthalmologist is your best resource for any concerns about your eye health. Do not hesitate to contact Pristine Eye Hospitals or your treating doctor if you have any questions or experience any worrying symptoms.
