1.Visual Acuity Exam

  • A measure of the clarity or sharpness of your vision
  • Performed on a routine basis for all new patients and returning patients every 3 months
  • Performed at Visual Acuity rooms on the 2nd floor
  • Please bring any glasses you are using with you to the Visual Acuity Exam

2.Tonometry Test

  • A measure of the intraocular pressure (pressure inside of your eye)
  • Often performed on a routine basis along with the Visual Acuity exam on the 2nd floor
  • Can be performed with the Air Puff non-contact tonometer or with the Applanation tonometer with anesthetic eye drops

3.Refraction Exam

  • A test which measures a person's prescription for eye glasses 
  • A test which measures if a person is near-sighted (myopic), far-sighted (hyperopic or presbyopic), or has an astigmatism
  • Performed if a person's visual acuity has dropped significantly or the person requests a prescription for glasses
  • Performed at Refraction rooms on the 2nd floor

4.Slit Lamp Examination

  • A detailed examination of the eye performed by the doctor using a slit lamp, an instrument with a high intensity light source and magnification allowing the doctor
  • Performed in the doctor's examination room


  • Sometimes ordered by your doctor to help the doctor see more details of your retina, a thin tissue at the back of the eye
  • A process in which eye drops are given, usually three times, to relax the muscles of the iris (the colored part of your eye); this enlarges the pupil (the round black circle in the center of your eye), allowing more light to enter the eye and the doctor to see more of your retina
  • Usually lasts 4 hours during which time you may not be able to read clearly
  • You may like to wear sunglasses when going outdoors after dilation, as your eyes may be uncomfortable in bright light until the pupil has constricted back to normal size
  • Do not drive for 4 hours after the dilation drops have been put into your eye
