Keratometry Quick Tip

This is a quick tip my supervisor taught me at work.

I previously had problems aligning the keratometer on a patients’ cornea - and she taught me the ‘pen-light technique’ - so thought I would share it with anyone who hadn’t heard it yet.

If you shine a pen-torch through the eyepiece of the keratometer, then the reflections of the mires become visible, and these can then be easily moved onto the central cornea using the joystick. If you then look through the eyepiece, the mires should now be visible.

This technique has saved me a lot of time and unnecessary hassle with patients during keratometry!
