What Human Epidermal Growth Factor (hEGF) is used for

Human Epidermal Growth Factor (hEGF) is a specialized eye medicine primarily used to help the surface of your eye heal. It is prescribed for:

Persistent epithelial defects: These are areas on the front surface of your eye (the cornea) that have not healed properly despite other treatments. The cornea has a protective outer layer called the epithelium, and when this layer is damaged and doesn’t mend, it can cause discomfort and affect vision. hEGF helps to encourage the regeneration of these cells.
Corneal healing: In various situations where the cornea needs assistance to repair itself, hEGF can be used to support the natural healing processes. This could be following injuries, infections, or other conditions that affect the corneal surface.

Essentially, if your eye’s front surface has a wound or defect that is struggling to heal, hEGF can be a crucial part of your treatment plan to encourage faster and more effective recovery.

How it works

The front surface of your eye, called the cornea, has a very important protective layer known as the epithelium. When this layer gets damaged, your eye needs to produce new cells to repair it. Human Epidermal Growth Factor (hEGF) is a natural substance that plays a key role in this process.

When hEGF eye drops are applied, they act like a signal to the cells on the surface of your eye. They stimulate these epithelial cells to grow, multiply, and spread, effectively helping to close the wound or defect. This process is called ‘epithelial regeneration’. By encouraging these cells to regenerate more effectively, hEGF helps in the faster and more complete healing of persistent epithelial defects and promotes overall corneal healing.

Think of it like a natural ‘booster’ for your eye’s own healing machinery, specifically targeting the repair of the surface layer of the cornea.

How it’s used

Human Epidermal Growth Factor (hEGF) eye drops are a specialized medicine and will be administered or prescribed to you by a qualified ophthalmologist at Pristine Eye Hospitals. The exact way you use these drops will depend entirely on your specific eye condition and the doctor’s instructions.

Dosing: The dosing of hEGF eye drops is ‘per protocol’. This means your doctor will create a specific schedule for you, detailing how many drops to use and how often. It is extremely important to follow these instructions precisely. Do not change the dose or stop using the drops without consulting your ophthalmologist.

Administration: Your doctor or a nurse will show you how to correctly instil the eye drops. Generally, for eye drops:

Wash your hands thoroughly with soap and water before touching your eyes or the medicine bottle.
Gently pull down your lower eyelid to create a small pocket.
Hold the dropper tip close to your eye, but be careful not to touch your eye or any other surface with the tip to prevent contamination.
Look upwards and gently squeeze the bottle to release the prescribed number of drops into the pocket you created.
Close your eye gently for a minute or two. Avoid blinking excessively or squeezing your eyes shut, as this can push the medicine out.
If you need to use more than one drop in the same eye, or if you are using other eye drops, wait at least 5-10 minutes between different drops to allow each medicine to be absorbed properly.
Replace the cap tightly on the bottle immediately after use.

Remember, hEGF is a hospital-prepared prescription medicine. It is crucial to use it exactly as directed by your ophthalmologist to ensure its effectiveness and your safety.

Always follow your ophthalmologist’s exact instructions.

Understanding Corneal Health and Healing

The cornea is the clear, dome-shaped front surface of your eye. It’s like the eye’s primary window, playing a crucial role in focusing light onto the retina and allowing us to see clearly. It also acts as a protective barrier against dust, germs, and other external elements. The outermost layer of the cornea is called the epithelium, which is very important for maintaining a smooth surface and protecting the inner parts of the eye. When this epithelial layer gets damaged, for example, due to an injury, infection, or certain medical conditions, it needs to heal quickly and completely. Sometimes, these defects or wounds don’t heal on their own as expected, leading to what doctors call ‘persistent epithelial defects’. These can cause ongoing pain, redness, blurred vision, and increase the risk of further complications. This is where specialized treatments like Human Epidermal Growth Factor (hEGF) come into play, helping to encourage the natural healing process of the corneal surface.

Maintaining good corneal health is vital for clear vision and overall eye comfort. Regular eye check-ups, especially if you experience any persistent eye discomfort, changes in vision, or redness, are essential. If you have been diagnosed with a corneal condition, following your ophthalmologist’s advice diligently is the best way to protect your eyesight and promote healing.

Correctly Using Eye Drops: A Step-by-Step Guide

Using eye drops correctly is crucial for them to work effectively and to prevent contamination. Many people find it a bit tricky at first, but with practice, it becomes easier. Here’s a general guide for instilling eye drops:

Wash Your Hands: Always start by washing your hands thoroughly with soap and water. This is the most important step to prevent introducing germs into your eye.
Prepare the Bottle: If the bottle has a cap, twist it off and place it on a clean surface, making sure the inside of the cap doesn’t touch anything. Do not touch the tip of the dropper.
Position Yourself: You can either sit or lie down, whatever is most comfortable for you. Tilt your head back slightly.
Create a Pocket: Gently pull down your lower eyelid with one finger to create a small pocket between your eyelid and your eye.
Instil the Drop: Hold the dropper bottle above your eye, about 1-2 cm away. Look upwards. Gently squeeze the bottle to release one drop into the pocket you created. Be careful not to let the tip of the dropper touch your eye, eyelid, or eyelashes, as this can contaminate the medicine.
Close Your Eye: Gently close your eye for about 1-2 minutes. Avoid blinking rapidly or squeezing your eyes shut, as this can push the medicine out. You can also gently press your finger against the inner corner of your eye (near your nose) for a minute or two; this helps prevent the medicine from draining into your tear duct and potentially causing systemic side effects.
Clean Up: If any excess liquid runs down your cheek, gently wipe it away with a clean tissue.
Replace the Cap: Put the cap back on the bottle immediately and tightly.
Multiple Drops/Medicines: If you need to use more than one drop in the same eye, or if you are using different types of eye drops, wait at least 5-10 minutes between each application. This ensures that each medicine has enough time to be absorbed and prevents one drop from washing out another.

Always follow the specific instructions given by your ophthalmologist regarding the number of drops and frequency of use. If you are unsure, do not hesitate to ask your doctor or the hospital staff for a demonstration.

General Eye Hygiene, Storage, and When to Seek Help

Good eye hygiene is fundamental for preventing infections and maintaining healthy eyes, especially when you are undergoing treatment for an eye condition. Always wash your hands before touching your eyes or applying any eye medication. Avoid sharing eye drops or other eye care products with anyone else, as this can spread infections. If you wear contact lenses, your doctor will advise you on when and if you can wear them during your treatment with hEGF eye drops. Often, it’s recommended to avoid contact lenses while treating active corneal issues.

Proper storage of your eye medicine is also very important. Always store your hEGF eye drops exactly as instructed by your ophthalmologist or pharmacist. Compounded medicines like hEGF may have specific storage requirements, such as refrigeration. Keep all medicines out of reach of children and pets. Do not use eye drops past their expiry date, or if the solution changes colour, becomes cloudy, or if you notice any particles in it. Discard the bottle after the recommended period, even if there is still medicine left.

It is crucial to know when to seek professional medical help. While using hEGF eye drops, contact Pristine Eye Hospitals or your ophthalmologist immediately if you experience any of the following:

Sudden worsening of eye pain, redness, or discomfort.
Any new or worsening changes in your vision.
Increased sensitivity to light.
Discharge from your eye.
Swelling around your eye.
Any allergic reaction symptoms, such as rash, itching, or difficulty breathing (though rare with eye drops, always be aware).
If you accidentally contaminate the dropper tip or suspect the medicine has been compromised.
