Important tricks every ophthalmologist should know while using a tonopen

To guarantee a precise and effective assessment with tonopen, ophthalmologists should keep the following advice in mind to ensure an accurate and efficient assessment:

 Let patients sit in a relaxed position; they shouldn’t struggle to reach the headrest. According to various research studies, patient positioning and constricting collars may impact IOP.

 Patients should concentrate on an area behind the technician. This prevents them from focusing on the tonometer tip, making themless likely to flinch as the device nears their eye.

 Instruct them to concentrate on keeping the other eye open wide; if they do so, applying pressure to the primary eye will be more challenging.

Instruct them to elevate their brows and open their eyes in a “surprised” manner. It is far more difficult to close their eyes while exercising their brow muscles to elevate their brows.

 If patients cannot open their eyes, you must hold them open without applying any pressure to the eyeball. This can be accomplished by applying pressure to the patient’s cheekbones and brow bone.

 When using a tonopen, make sure the patient is looking ahead. An increase in IOP can be seen if the patient is looking superiorly, and a decrease in IOP can be seen with an inferior gaze.

 Always start with the same pressure on the dial. Do not set the dial’s number to the most recent IOP because doing so could make it simpler to “cheat” and convince yourself that you are close enough.

After some practice, you can determine how far to turn the dial simply by looking at the mires when you first make contact.

 Once you’ve taken an IOP, examine the cornea. You will receive priceless information from this, such as any stains left behind from taking the measurement, which can help develop an improved technique. Also, you can observe alterations in corneal staining that weren’t necessarily there when the drop was first injected.

 Finally, calibrate frequently and maintain all instruments’ safety, cleanliness, and functionality.

Conclusion

By following these tips and using the appropriate tonometer device for eachpatient,ophthalmologistscanobtainaccurate IOP measurementsand provide the best possible care for their patients.
