Idrees Floaterscope

Product Number: 18008
Idrees Floaterscope

Purchase the Idrees Floaterscope from Gulden.  This unique device can be used to quantify the location and density of a patient's floaters.  Use it before and after vitreolysis surgery to document outcomes.


This device was developed in partnership with Dr. Mohammed Idrees, FRCS(Edin)

This product is designed to help patients identify the location and number of their floaters.  Patients should use the floaterscope to indicate how many floaters appear in their vision and, specifically, in which quadrants of their vision those floaters appear.  Using this device will help the ophthalmologist know where to focus when performing vitreolysis surgery.  The patient should use the floaterscope again after surgery to confirm that all floaters have been removed. 


  1. Pick up the product.  Gently pull the smaller telescoping LED tube until it is fully extended. 
  2. Press the button on the rear of the LED tube to turn on the light.
  3. Hold the eyepiece (black end) up to either the right or left eye.
  4. Peer through the pinhole until the crosshairs (four quadrant) lines are visible.
  5. Rotate the device until the crosshairs are oriented vertically and horizontally.
  6. Observe the quantity and location of floaters in each quadrant (top left, top right, bottom left, and bottom right).
  7. Record observations (quantity and location of floaters) and repeat for the other eye.
  8. Press the button on the rear of the LED tube to turn off the light.
  9. Slide the small telescoping LED tube back into the large tube for storage.


  • To change the batteries, turn the round cap on the LED tube counterclockwise until it separates from the tube.  A cylinder which contains the three AAA batteries will then slide out of the LED tube.  Place three batteries in the cylinder according to the markings (positive and negative).  Insert the cylinder back into the LED tube and tighten the cap by turning clockwise.
  • To clean the device, use an alcohol wipe to quickly wipe the black eyepiece.  Ensure that the alcohol wipe is not dripping wet.  No liquid should enter the eyepiece pinhole.
