Area of Science:

  • Ophthalmology
  • Medical Devices
  • Sterilization Techniques

Background:

  • Tonometer prisms require regular sterilization for accurate intraocular pressure measurements.
  • Current sterilization methods can be cumbersome or potentially damage delicate tonometer components.

Purpose of the Study:

  • To present a simple, cost-effective, and efficient tonometer prism holder for improved sterilization.
  • To demonstrate a method for preventing damage to tonometer prisms during disinfection.

Main Methods:

  • Construction of a tonometer prism holder using a readily available eyedrops bottle.
  • Design incorporates a reservoir for renewing disinfectant around the tonometer tip after each use.
  • Leakproof design to prevent disinfectant spillage.

Main Results:

  • The holder allows for immersion of only the tonometer prism tip in disinfectant.
  • Prevents damage to the proximal end of the tonometer prism.
  • Ensures consistent sterilization through disinfectant renewal.
  • Leakproof construction provides safety during handling and storage.

Conclusions:

  • This DIY tonometer prism holder offers a practical solution for maintaining tonometer hygiene.
  • It is a cost-effective and user-friendly method for consistent and safe sterilization.
  • The design protects the tonometer prism while ensuring its readiness for clinical use.
