Cornea
The cornea, positioned just in front of the iris and pupil, constitutes the eye's anterior surface, enabling the admission of light into the eye.
The cornea is the clear, dome-shaped front surface of the eye that acts as a protective layer and helps to focus light onto the retina.
It plays a vital role in vision. Various conditions can affect the cornea, leading to vision problems.
Symptoms : If you have keratoconus, you may observe:

In advanced keratoconus, one may need corneal transplantation (complete / partial layered) depending on the stage of disease. With the availability of the most advanced techniques,better results and faster recovery is ensured.
This minimally invasive process enhances corneal strength by inducing crosslinking of collagen fibres. C3R helps in stabilizing keratoconus in early stage and prevents further progression of disease and need of corneal transplantation.
Yes, the cornea can be affected by various diseases and conditions, including infections, injuries, degenerative disorders, corneal dystrophies, and autoimmune disorders. These conditions can cause corneal inflammation, scarring, thinning, or irregularities, leading to vision problems.
Corneal problems may cause symptoms such as blurred or distorted vision, eye pain or discomfort, redness, sensitivity to light, excessive tearing, foreign body sensation, and reduced visual acuity.
Yes, many corneal disorders can be treated. The specific treatment depends on the underlying condition. Some common treatment options include medications, eye drops, contact lenses, corneal transplantation (keratoplasty), and in some cases, refractive surgery.
The healing time after corneal transplantation can vary from several weeks to several months. It depends on various factors, including the type of transplantation, the individual's overall health, and the specific condition being treated.
Improper use, poor hygiene, or extended wear of contact lenses can potentially cause corneal problems. These may include corneal abrasions, infections (such as microbial keratitis), and corneal ulcers. It is important to follow proper lens care instructions and have regular check-ups with an eye care professional when using contact lenses.
No, corneas for transplantation are obtained from deceased donors. The cornea is a unique tissue in that it does not require blood supply, allowing it tobe successfully transplanted from a deceased individual to a recipient.
Laser-assisted in-situ keratomileusis (LASIK) is a popular refractive surgery to correct nearsightedness, farsightedness, and astigmatism. It involves reshapingthe cornea using a laser. While LASIK is generally safe and effective, it does involve altering the corneal tissue, and potential risks and complications canoccur. It is important to consult with an experienced eye surgeon to determine if LASIK is suitable for you.
The cornea is the clear, dome-shaped outermost layer at the front of theeye. It plays a crucial role in focusing light onto the retina, which is essential forclear vision.
A: The cornea acts as a protective barrier for the eye and helps to refract orbend incoming light, directing it to the lens and then the retina. It contributessignificantly to the eye's ability to focus on objects at various distances.
Corneal transplantation, also known as keratoplasty, is a surgical procedurewhere a damaged or diseased cornea is replaced with a healthy cornea from adonor. It is often performed to improve vision or alleviate pain in cases whereother treatments have not been successful.
