8 Facts on Cornea and Corneal Disease

8 facts on cornea and corneal disease

The cornea, apart from being one of the main components of the eye, is sensitive and prone to complications. Maintaining a good eye health goes a long way in keeping the cornea healthy and lowering the risks of corneal diseases.

These 8 interesting facts about cornea and corneal disease can help you take better care of your eyes:

1. Where is the cornea located in the eye?

The cornea is located in the outermost dome-shaped layer of the eyes. Cornea covers the front part of the eyes and plays a crucial role in focus of the vision.

2. The cornea is a highly organised tissue:

The cornea may seem a clear covering but the tissue is much more than that as it is made up of three multiple layers, including Epithelium, Bowman’s Layer, Stroma, Descemet’s membrane, and Endothelium.

3. Tears are important to the cornea:

The cornea is different from most of the other tissues in the body; it doesn’t contain any blood vessel which can nourish it. Instead, it’s the aqueous humor and tears that nourish the cornea.

Every time we blink, the tears get distributed across the cornea to keep the eyes moist, protect against infection, and help heal wounds.

4. Importance of cornea:

One of the main purposes of the cornea is to focus light on the retina, the light-sensitive tissue at the back of the eye. The cornea refracts the incoming light onto the lens which, in turn, refocuses to the retina. Apart from redirecting light, the cornea protects the lens and the retina from the harmful ultraviolet rays present in sunlight. The cornea also provides an overall protection to the eyes by acting as a barrier against germs, dirt, and other particles.

5. The cornea can heal itself:

The cornea can heal in its own from minor scratches and injuries. However, serious injuries can cause scarring in the cornea which, in turn, can lead to vision impairment. Some of the common implications of serious injuries in the cornea include:

  • Reduced vision
  • Blurred vision
  • Pain in the eye
  • Headache
  • Sensitivity to light
  • Inflammation in the eye
  • Redness in the eye

6. Different types of corneal diseases:

There are various disorders that affect the cornea. Some of the common ones include Keratitis, Corneal Ulcer, Keratoconus, Bullous Keratopathy, Fuchs’ Endothelial Dystrophy, Recurrent Corneal Erosion, Corneal Perforation, Corneal Neovascularisation, Iridocorneal Endothelial Syndrome, and Corneal Dystrophy.

7. Common causes of corneal disorders:

There are several causes of corneal disorders. The common ones include infections, trauma, allergies, thinning (Ectasia), nutritional deficiencies, and autoimmune disorders. Damages to the cornea can also be caused by common eye conditions such as glaucoma, eyelid disorders, and dry eye (tear film abnormalities).

8. Complications of corneal disorders:

Corneal disorders, if not treated, can worsen and lead to complications such as eye pain and vision loss. If you have a corneal disorder, it is crucial to review the treatment options with an eye specialist.

Contact Lens FAQS and Answers

Contact Lens FAQS and Answers
If you are using contact lenses for the first time, then there might be a lot of questions running through your mind. From taking care of the contacts to replacing them, here we have tried to address all the concerns related to contact lenses.

1. What are the different types of contact lenses and which one’s best for my eyes?

There are daily disposable lenses, monthly and two-week disposable lenses. Also, contact lenses come in a wide range of materials. Some materials used in the contact lenses are less prone to drying while some materials may better resist deposits than others. There are lenses for correcting astigmatism along with farsightedness and near-sightedness while some provide extra reading correction. The lens that is best for you depends mostly on your visual needs, your budget, and how often you want to replace them. The lenses that need frequent replacement are a little more expensive as you will be using a lot more of them. However, they need less cleaning and maintenance.

2. Does it takes longer to get used to them?

It depends mostly on the type of lenses you are using. Most of the lens users get used to soft (silicone or hydrogel) contacts pretty easily or in a few days. However, if you are using hybrid contact lenses or rigid gas permeable lenses, it might take a few weeks or longer for your eyes to get used to them. In very rare cases, you may not ever feel comfortable while wearing contact lenses.

3. Can I lose contact lenses behind my eyes?

Not at all. At worst, you may have trouble finding the lenses as they may get under the upper eyelid when you rub your eyes. This can dislodge the lens. Talk to your eye doctor in case you need help in locating and removing the lens.

4. Is it wise to wear disposable contact lenses?

Often, doctors suggest disposable contact lenses. In terms of health, these are the good choice as there are fewer opportunities for bacteria to grow on the lenses. Also, if you are wearing these lenses, you will be discarding them at the end of the day. And as such you don’t need to buy contact lens solution and clean them regularly. These are hassle-free.

5. Is there a great difference between extended wear and daily wear contact lenses?

Yes, there’s a huge difference. Extended wear contacts are made using special materials and they allow more oxygen to enter your eyes. |
6. Who can wear contact lenses? What’s the perfect age to start wearing one?

Anyone can wear contact lenses. They can treat vision issues such as astigmatism. Multifocal contacts, on the other hand, can help treat presbyopia. Children too can wear contact lenses if they are mature enough to take care of the lenses and maintain personal hygiene.

7. How long can I wear the lenses?

Most people can wear the lenses pretty comfortably throughout the day (usually 16 hours). If you are prone to dry eyes, then you may have to limit your wearing time. Some contact lenses are good for longer wear. If you don’t feel comfortable wearing a particular lens, you can try other options and different lens.

All lenses have a particular replacement schedule. There’s a schedule for how many days you can wear them before they are discarded. Usually, the replacement schedule is like every day or every 14 days, or every 1 month.

We hope that these answers will help you get an idea about the usage of contact lenses.

Take Care of Your Eyes

If you wear lenses, then take proper care of your eyes to avoid any kind of infection. Here is how you can keep your eyes safe:

15. Wear your contacts as per your doctor recommends. Wear them as long as the doctor thinks it’s necessary.

16. In case you cannot keep track of the time when to change your lenses, ask your eye doctor to give you a chart for tracking your schedule. Or else, make a chart for yourself.

17. NEVER EVER wear someone else’s contact lenses, especially if its wearer already uses those lenses. Using other’s contact lenses can get you eye infections or other foreign bodies from their eyes to yours.

18. NEVER sleep with your contact lenses in. Avoid doing it unless you have an extended-wear lens. When you close your eyelids, your tears don’t get much oxygen to your eyes compared to when it’s open. So, take the lenses off before going to sleep.

19. When going out, wear sunglasses with complete UV protection. You can even wear a hat. Contact lenses make your eyes light-sensitive.

20. Keep your eyes moist and use a rewetting solution (if only recommended by your doctor).

21. Often people accidentally wear contact lenses inside out. Although this doesn’t hurt it doesn’t feel good even. In order to avoid this keep the lens on the tip of your finger so that it forms a cup. Now, look at the contact from the side. If the cup of the lens appears like it flares out at the top and has a lip that means the lens is inside out. And if it appears like the letter “U,” then it is the right side out.

22.
If wearing contact lenses gets your eye irritated, take out the lenses. Talk to your doctor and do not wear them until as suggested by the doctor. If you continue wearing them, your eye will get infected.

23. In case you have sudden vision loss or have a blurred vision that won’t get better; if you experience light flashes, swelling and unusual redness in your eye, go to your eye doctor right away.
