From Face-Timing Marco about the trip to Guatemala, we found out that his experiences with diagnosing and making eyeglasses reaffirmed the problems with the device that were already known. Although the diagnostic tool shows promise, the measurements as compared with those of Dr. Bob Lipski are still unacceptable so either a new device needs to be made or the current one refined. According to Marco, the process of giving directions during the diagnosing was one of the key factors that contributed to the success or failure of the diagnosis. When only the diagnostic tool was used, the results were far off, but when used with the lens kit, the accuracy improved. Marco also indicated that the diagnostic tool was much more inaccurate for patients who were far-sighted; this is an item of concern if we want to improve accuracy. For one patient who was astygmatic, the diagnosis was spot on (verified the results of diagnostic tool with lens kit and with her old glasses). Marco speculated that this was because the child had experience with eye doctors and the entire examination process; as such, she already knew what to look for). This is an indication that we need to find a way to help people better understand what they are looking for when using the tool. Another suggestion is to take the patient’s subjectivity out of the process entirely if possibly (in other words, there is no patient feedback but the diagnosis relies soley on the diagnostician).
Summary of what needs to be done currently/ listing options:
- adapting the current grinding machine to make more square (more ‘modern’) lenses for more western-styled frames
- improving the diagnostic procedure:
1. explore alternatives to current device- modified retinoscopy possibly- this entails making our own lens kit
2. focus on the diagnostic process itself- focus on astygmatic wheel first and then the scope
3. look for ways to combine device with retinoscopy for better accuracy- suggestion by Marco as well- using the tools together in Guatemala helped
* seems to be the most promising direction
4. develop way to help patients learn what they are looking for when using the tools – teach them how to use tool before actually using it- write manual?
5. regardless of direction- I personally need to become more familiar with the current tool
- refine the devices (grinder and diagnostic) so that they can be made in Guatemala…issues finding materials needed like router…
