Cornea & Corneal Disorders
The cornea is the clear, dome-shaped front surface of the eye. It plays a crucial role in focusing light onto the retina — much like the lens of a camera. Because it provides nearly two-thirds of the eye’s focusing power, even small changes in the cornea can significantly affect vision.
When the cornea becomes infected, injured, swollen, or irregular in shape, vision may become blurred, distorted, or painful. Early diagnosis and timely treatment are essential to prevent long-term damage and preserve sight.
Blurred or distorted vision
Redness or persistent irritation
Sensitivity to light (photophobia)
Excessive watering or discharge
Difficulty wearing contact lenses
Eye pain or foreign body sensation
Visible white or grey spot on the eye
Sudden or gradual changes in vision
Keratoconus A progressive condition where the cornea becomes thin and bulges into a cone shape, leading to distorted and blurry vision.
Corneal Ulcer An open sore on the cornea, usually caused by infection. This is a medical emergency and requires immediate treatment to prevent permanent vision loss.
Dry Eye Disease A tear film imbalance can cause burning, irritation, fluctuating vision, and surface damage to the cornea.
Corneal Dystrophies A group of inherited conditions that cause abnormal deposits or clouding within the cornea, affecting clarity over time.
Corneal Scarring / Opacities Scars from injury, infection, or previous surgery can reduce transparency and affect vision.
Bacterial, viral, or fungal infections
Eye injuries, scratches, or chemical exposure
Genetic (inherited) disorders
Chronic dry eye or autoimmune inflammation
Improper contact lens hygiene or overuse
Age-related changes affecting inner corneal cells (such as endothelial disorders)
Excessive ultraviolet (UV) exposure
Medical conditions such as diabetes
Complications after eye surgery
Treatment Options for Corneal Disorders
Medicated Eye Drops & Oral Medication
Used to treat infections, inflammation, swelling, and dry eye conditions.
Corneal Cross-Linking (CXL)
A minimally invasive procedure that strengthens a weak cornea in keratoconus and helps stop disease progression.
Specialty Contact Lenses
Rigid Gas Permeable (RGP) or scleral lenses improve vision in patients with irregular corneas.
PTK (Phototherapeutic Keratectomy)
A laser procedure used to remove superficial scars and smooth corneal surface irregularities.
Corneal Transplant (Full or Partial)
In advanced cases, damaged corneal tissue is replaced with healthy donor tissue to restore clarity and vision.

Clear Answers for Better Vision
What is the cornea?
The cornea is the clear, dome-shaped outermost layer at the front of the eye. Often referred to as the “window of the eye,” it plays a vital role in focusing light and protecting the inner structures of the eye from dust and germs.
What are the most common corneal problems?
Our specialists at ASG frequently treat a variety of corneal conditions, including:
Keratitis: Inflammation or infection often caused by bacteria or viruses.
Corneal Abrasions: Scratches on the surface of the eye.
Corneal Ulcers: Serious open sores usually resulting from infection.
Keratoconus: A condition where the cornea thins and bulges into a cone shape.
Corneal Dystrophies (e.g., Fuchs’ Dystrophy): Genetic conditions causing cloudiness.
Pterygium: A non-cancerous growth that can spread onto the cornea.
What symptoms might indicate a corneal problem?
You should visit a specialist if you experience:
Blurred or distorted vision.
Persistent eye pain or redness.
Extreme light sensitivity (photophobia).
Excessive tearing or unusual discharge.
The sensation of having a foreign object in your eye.
How is a corneal condition diagnosed at ASG Eye Hospital?
We use advanced diagnostic technology, including Slit-Lamp Microscopy and Corneal Topography, to map the surface of your eye. These tools allow our surgeons to observe individual corneal layers and detect microscopic changes early.
Can a scratched cornea heal on its own?
While minor abrasions may heal within 24–48 hours, they should always be evaluated by a professional. An untreated scratch can lead to a Corneal Ulcer or serious infection, which can permanently impair your vision.
What treatment options are available for corneal diseases?
At ASG, treatment is customized based on the diagnosis:
Medical Management: Specialized antibiotic or anti-inflammatory eye drops.
Specialty Contact Lenses: Scleral or Rose-K lenses for Keratoconus.
C3R (Corneal Collagen Cross-linking): To strengthen the cornea and stop the progression of Keratoconus.
Corneal Transplant: Replacing damaged tissue with healthy donor tissue.
What is a corneal transplant (Keratoplasty)?
A corneal transplant is a surgical procedure where a damaged or diseased cornea is replaced with healthy donor tissue. ASG Eye Hospital is equipped with advanced surgical suites to perform both full-thickness and partial-thickness (DALK/DSEK) transplants.
How safe is a corneal transplant?
Corneal transplants are highly successful. While all surgeries carry some risk, such as graft rejection or infection, our surgeons use precision techniques to minimize these. Regular post-operative follow-ups at ASG ensure the best long-term results.
How can I prevent corneal injuries and diseases?
Always wear protective eyewear during sports or industrial work.
Maintain strict hygiene if you wear contact lenses (never sleep in them).
Treat chronic “Dry Eye” promptly to prevent surface damage.
Schedule regular eye exams to catch genetic conditions early.
When should I see an ASG Cornea Specialist?
Seek immediate care if you experience sudden vision loss, persistent pain after an injury, or if you have a “white spot” appearing on the clear part of your eye. Early intervention is the key to preventing permanent scarring.
