Brief Summary

This is a study comparing a new treatment for bacterial keratitis (also known as corneal ulcers) with the current standard of care. It is a randomized trial, and the investigators plan to test whether besifloxacin (a new antibiotic) in comparison to the current standard of treatment, fortified antibiotic drops (cefazolin and tobramycin).

Outcome Measures

Primary Outcomes (1)

  • Time to microbial sterilization of the infected cornea

    We will take repeat cultures and determine when no more bacteria can be cultured

Secondary Outcomes (5)

  • Time until closure of epithelial defect

    2-14 days

  • Final pinhole corrected visual acuity

    4 months

  • Final corneal scar size

    4 months

  • Severe adverse events: corneal perforation, endophthalmitis

    4 months

  • Time until clinical resolution as determined by physician

    4 months

Study Arms (2)

Group A: Besifloxacin

EXPERIMENTAL

Patients presenting with bacterial keratitis. These patients will be treated with besifloxacin ophthalmic suspesnion 0.6%, initially 6x a day and tapered down as the patient's condition improves based on the clinical judgement of the treating physician.

Drug: Besifloxacin

Group B: Fortified Antibiotics

ACTIVE COMPARATOR

Patients presenting with bacterial keratitis. These patients will be treated initially with fortified cefazolin and vancomycin drops every 1 hour around the clock (24hours) for a minimum of 48 hours, and will subsequently have their dosages tapered gradually by the treating physician as is the standard of care for bacterial keratitis.

Drug: Tobramycin and Cefazolin

Interventions

Group A: Besifloxacin

Fortified Tobramycin and Cefazolin eye drops

Group B: Fortified Antibiotics
