With a rise in healthcare-acquired infections, proper care and cleaning of ophthalmic instruments is essential, especially at the eye doctor. From sterilization to proper storage, each step of the cleaning process is important for minimizing infection risks for patients and staff. With a caveat that one should always follow manufacturer instructions and current American Academy of Ophthalmology (AAO) guidelines, we present: a quick and simple guide to cleaning your Haag-Streit tonometer’s measuring prisms. For the full in-depth process, refer to this link.
Carefully remove the measuring prisms from their holder. Thoroughly rinse the prisms under running water for 60 seconds. Clean the measuring prisms with an AAO approved, pH neutral material until all residue has been removed. Thoroughly rinse your cleaning material under cold, filtered running water for 60 seconds. Produce a fresh, lint-free, disposable cloth for drying the measuring prisms. Manually inspect the newly-dried measuring prisms to ensure that they are completely clean and in working condition. Place your prisms in a sterile plastic tray until they are ready for disinfection.
Note: be sure to thoroughly rinse all ophthalmic instruments thoroughly after each use to prevent any residue from drying onto them.
Prepare your Desinset cleaning kit for disinfecting your prisms. Remove the measuring prisms from the plastic tray and place them on the bottom level plastic insert (the top level is for contact lenses), and place the insert into the Desinset measuring beaker. Slowly add in an AAO approved disinfecting solution until all of the measuring prisms are fully immersed – 600 ml is recommended. Leave the prisms submerged for at least 10 minutes to ensure ample time for the disinfectant to work. Do not let the prisms be exposed for more than 60 minutes. Remove the Desinset plastic insert with the measuring prisms once the submersion period is complete and let the instruments air dry. Get your second, sterilized measuring beaker from your Desinset cleaning kit and place the newly-dried measuring prisms and Desinset plastic insert inside.
- Final Rinse
Align and place your sterile Desinset kit funnel at the top of your plastic insert, and use it to rinse the measuring prisms with cold, filtered running water for 10-15 minutes. Once the final rinse cycle is complete, remove the plastic insert with the prisms from the measuring beaker and use a soft, lint-free, disposable cloth to dry each individual instrument.
- Proper Storage and Inspection
Use your Desinset lens container to store the measuring prisms until their next use. Make sure to thoroughly inspect each instrument before each use to ensure there is no residue, contaminants, or damage to the instrument. Perform your pre-use examination with a slit lamp microscope at 10x – 16x magnification.
