Corneal infections—also known as keratitis—occur when bacteria, viruses, fungi, or parasites infect the cornea, the clear front surface of the eye. In Karachi, where dust, humidity, and contact lens use are common, corneal infections are a frequent cause of urgent eye care visits. Prompt diagnosis and treatment are essential to prevent permanent vision loss.

Causes of Corneal Infections

Corneal infections can result from several factors, including:

  • Contact lens misuse: Wearing lenses for too long or improper cleaning.
  • Eye trauma: Small scratches or injuries allowing microbes to enter.
  • Contaminated water exposure: Swimming or washing the face with unclean water.
  • Pre-existing eye diseases or surgeries.

In Karachi’s environment, bacterial and fungal infections are particularly common due to the warm climate and frequent dust exposure.

Common Symptoms to Watch For

Symptoms of corneal infections can develop quickly and should never be ignored. These include:

  • Intense eye pain and redness
  • Blurred or hazy vision
  • Excessive tearing or discharge
  • Sensitivity to light
  • A white or gray spot on the cornea

If any of these occur, seek medical attention immediately. Early intervention can make the difference between full recovery and lasting visual impairment.

Treatment Options Available in Karachi

The treatment for corneal infections depends on the underlying cause. Eye specialists may prescribe:

  • Antibiotic, antifungal, or antiviral eye drops to target the infection
  • Cultures and lab testing to identify the exact organism
  • Advanced corneal imaging for precise diagnosis
    In severe cases, patients may require corneal surgery or transplant if the infection leads to scarring.
