Bacterial keratitis is a serious eye infection that affects the cornea—the clear, front part of the eye. It often develops rapidly and can threaten vision if not treated promptly. Knowing the symptoms and seeking immediate care from a qualified eye specialist in Karachi is essential for preventing permanent damage.

What Causes Bacterial Keratitis?

This condition usually occurs when bacteria enter the cornea through a break or injury. Common risk factors include contact lens wear, eye trauma, or pre-existing eye diseases. In Karachi’s humid environment, bacterial infections can spread quickly, especially when contact lens hygiene is poor or contaminated water is used for cleaning lenses.

Symptoms You Should Never Ignore

Bacterial keratitis often begins suddenly. You may notice:

  • Severe eye pain or redness
  • Blurred or decreased vision
  • Sensitivity to light
  • Watery or thick discharge
  • A white or gray spot on the cornea

If you experience any of these symptoms, seek urgent evaluation. Delaying treatment can lead to corneal scarring, infection spread, and even vision loss.

Treatment Options in Karachi

Treatment depends on the severity and the bacteria causing the infection. Most patients require antibiotic eye drops, sometimes administered every hour during the first phase of treatment. Severe cases may need cultures, fortified antibiotics, or hospitalization for close monitoring.

At The Eye Center – Dr. Mahnaz Naveed Shah & Associates, specialists diagnose bacterial keratitis using advanced slit-lamp imaging and laboratory testing to ensure targeted, effective therapy.

Preventing Future Infections

Proper lens hygiene, avoiding overnight lens wear, and protecting your eyes from injury are key preventive steps. Regular eye check-ups can also help detect early signs of corneal irritation before infection develops.
