What is the cornea?

The cornea, a transparent layer at the front of your eye alongside the sclera (the white part), is a protective barrier against contaminants such as dirt and germs. Additionally, it plays a pivotal role in your vision. When light enters your eye, it is refracted or bent by the cornea. Any damage to the cornea, whether from disease, infection, or injury, can lead to scarring that impacts your vision by obstructing or distorting the incoming light.

Preventing Corneal Problems

To minimise the risk of corneal issues, it's essential to adhere to strict hygiene practices, especially if you wear contact lenses. Misuse of contact lenses is a primary factor in developing corneal diseases. Following these guidelines can reduce your chances of corneal infections:

  • Do not sleep with your contact lenses in.
  • Avoid rubbing your eyes, as it can alter the shape of the cornea.
  • In emergencies, such as injuries involving sharp or blunt objects, accidental exposure to chemicals, or the inadvertent entry of household disinfectants or toilet cleaners into your eyes, seek immediate assistance from a cornea specialist to initiate prompt treatment and prevent long-term complications.
  • Do not use over-the-counter eye drops for redness or watering of the eyes.
  • Never use steroid eye drops without a proper prescription from a registered eye specialist.
  • Feeling Like Something Is Stuck in Your Eye?

    If you have a sensation of something being stuck in your eye, consider these steps:

  • Blink several times.
  • Rinse your eyes with clean water.
  • Gently pull your upper eyelid down over your lower eyelid.
  • Refrain from rubbing your eye, as this could scratch the cornea.
  • If an object is lodged in your eye, do not attempt to remove it alone; instead, promptly consult your eye doctor or visit the emergency room.
  • When to Seek Immediate Assistance

    Seek immediate medical attention if you experience any of the following:

  • Intense eye pain
  • Change in vision
  • Blurry vision
  • Very red, watery eyes
  • An object stuck in your eye
  • A serious eye injury or trauma — like getting hit hard in the eye

    Risk Factors for Corneal Issues

    Keratitis (Inflammation)

    Dry eye

    Keratoconus or corneal ectasia

    Corneal dystrophies


    1- Can frequent rubbing of eyes cause corneal disorders?

    Yes, habitual rubbing of eyes is known to cause permanent changes in the shape of the cornea and corneal thinning and is associated with a condition called keratoconus or simply conical shaped cornea.

    2- What are the dos and don’ts of contact lens use?

    Contact lenses are thin transparent lenses that can be used as a substitute to spectacles. They are placed directly on top of the cornea. Regular cleansing of lenses before and after use, using contact lens solution within 6 months of opening the bottle, regular cleansing of the contact lens case and replacing them timely, restricting usage to 8 hours/day, avoiding overnight use, regular replacement and avoiding dust/water from directly touching the lens; are some practices for good hygiene. Immediately remove and discontinue using your contact lenses if you develop redness or pain while wearing them and consult your ophthalmologist urgently.

    3- What is keratoconus?

    Keratoconus is a condition characterized by progressive protrusion and thinning of the cornea, which can lead to decreased vision, frequent change in glasses especially the cylinder, and white spot on the cornea in advanced cases. It is usually seen in patients with history of allergic eye disease accompanied with frequent eye rubbing. The various treatment options available are spectacles, specialised contact lenses, collagen crosslinking (corneal strengthening), intracorneal rings, laser vision correction with crosslinking and implantable phakic lenses. Early detection and management is the key to a successful outcome.

    4- What is corneal transplantation surgery?

    Diseases of the front transparent part of the eye (like a watchglass) known as cornea, can lead to white spots/scar causing blindness. These patients may not be treated with medications alone, and require a surgical replacement of the white cornea by a clear cornea which is called as corneal transplantation. In this procedure, either the entire or a few layers of clear cornea from a deceased donor is transplanted into the patient’s eye.

    5- Why my eyes get tired after day’s computer work ? What is computer vision syndrome?

    Computer vision syndrome or digital eyestrain is a condition that occurs due to looking at computer/mobile or other screens for long periods of time. This occurs due to inability of eye muscles to recover from the strain caused by constant focusing on a near target, and may result in dry eyes. Taking regular breaks (at least for 20 seconds every 20 minutes), placing the monitor at least 25 inches away from eye, reducing monitor brightness, using anti-glare spectacles, blinking frequently and using lubricating eye drops help in reducing symptoms.

    6- What is Dry eye? How common is dry eye problem?

    Currently, 32% of the Indian urban population suffer from Dry eye disease in the age group of 21-40 years and it is expected that by 2030, it will increase to 45%. Dry eye disease occurs if there is an insufficient supply of tears or if the tears evaporate too quickly. It is a progressive disease and if left untreated, can lead to serious vision problems.

    7- Who is at risk of getting dry eye?

    You are prone to develop dry eye at any age, but more likely to develop the condition as you grow older. People who wear contact lenses, use computers or other screens for long periods of time, and/or live in dry, windy climates are also at increased risk of developing dry eye. Dry eye is more common in women, and is particularly common in post-menopausal women.
