Overview
The cornea is the transparent front surface that provides most of the eye's focusing power. Infections, injuries, dystrophies and surface inflammation can blur vision and cause significant discomfort. Corneal care ranges from medical treatment of infections and allergies to specialised procedures for thinning or scarred corneas.
Symptoms & Warning Signs
- Redness, pain or light sensitivity
- Foreign-body sensation
- Watering or discharge
- Blurred or hazy vision
- White spot on the cornea
Possible Causes
Corneal problems arise from infections (bacterial, viral, fungal), contact-lens misuse, trauma, allergies, inherited dystrophies and degenerations.
When to Consult an Eye Specialist
A painful red eye, especially in a contact-lens wearer, or any white spot on the cornea needs same-day evaluation — delays can permanently affect vision.
Diagnostic Process
- Slit-lamp examination with fluorescein staining
- Corneal topography and tomography
- Microbiological scraping for suspected infection
- Anterior segment OCT where indicated
Management & Treatment Approaches
- Prescription eye drops for infection or inflammation
- Bandage contact lenses and surface procedures
- Corneal cross-linking for progressive thinning
- Corneal transplantation for advanced scarring, where indicated
What to Expect
Most corneal consultations involve a microscope examination and, if needed, painless imaging. Infections may need close follow-up until healed.
Risks & Limitations
Untreated corneal infections and ulcers can scar the cornea and permanently reduce vision. Treatment risks vary by condition and will be explained before any procedure.
Recovery & Follow-up
Surface infections may heal in days to weeks; surgical recovery takes longer with structured follow-up. Complete the full course of prescribed medication.
