    An Alger brush is the most widespread kind of corneal drill. It is utilised to eliminate a rust ring after a metallic foreign body is taken from the corneal epithelium. The cornea is the broad, clear outside shielding covering of the anterior piece of the eye. It is very widespread for metallic particles to become embedded in the cornea even when security crystal is worn. The Alger brush is the best corneal drill because it values centrifugal force. This assists to minimize risk of corneal penetration because the drill self-stops when it comes to the basement membrane of the cornea.
   
   • Anesthetize the cornea utilising Proparacaine, Lidocaine or Tetracaine. One fall of anesthetic is sufficient. The cornea will be anesthetized nearly immediately.
   
   • Instruct the persevering to find a goal to gaze at and to hold his eyes open wide. Make certain the main heading in which he is looking permits you the best get access to the foreign body.
   
   • Remove the metallic foreign body. This is best finished with a corneal spud (a little surgical equipment that examines like a spatula) or a fine measure hypodermic needle. Approach the cornea tangentially with the equipment rather than of perpendicularly. Position the equipment under the demonstration of the metallic element and softly raise, flicking it off the cornea. Removing the foreign body is the so straightforward part.

   • Try to eliminate the rust ring with the spud or needle. You have more command than you will with the Alger brush and you will impairment less of the epithelium. Although the Alger brush is very calm, it does make a supple whirring sound. This can be very disconcerting to a currently apprehensive patient.
   
   • Remove the residual rust with the Alger brush. Turn the equipment on by rotating the peak of the instrument. There is a projectile that displays you which way to rotate it to turn it on. Hold the equipment in order that you have the most command over it. Brace your hand contrary to the slit light or brace your elbow contrary to the slit light table to double-check that your hand is steady.
   
   • Reposition the persevering, producing certain she is still and holding her eyes open wide. If the persevering will not contain her eyes open, you will require having an aide sustain the patient's top eye top with a swab.
   
   • Apply the alger brush tangentially to the cornea. Move the tilt of the brush over the rust tinted, oxidized piece of the cornea. This eliminates the impaired epithelium. Keep the locality you are debriding as little as possible. But don't be aghast to press solidly into the cornea, recall the equipment will halt itself if you are pushing too deep. Keep going the tilt over the rust ring until all of the discolored epithelium is gone.
   
   • Instill one fall of sodium flourescein to ascertain the span of the wound. Treat the wound topically like a corneal abrasion counting on the extent. Typically, prescribe one fall of a very broad spectrum antibiotic four times a day for four days.
