  Overview

  • Cornea is outer layer of the eye
  • Tearing away of this layer leads to corneal abrasion.
  • Most common injury to the eye
  • Multiple nerve endings present in cornea, hence painful
 

Causes

May be caused by

  • A finger nail
  • Any sharp flying object like pencil, glass

Treatment
  • Antibiotic used to prevent infection
  • Examination is done after using an anaesthetic
  • Pain returns after anaesthetic is stopped
  • Repeated usage of anaesthetic is harmful
  • Eye ointments, pain relievers are provided
  • A ‘patch’ may be put on the eyes
  • Eye ointments/ lubricants at night prevents recurrence
 
Do Not
