NIDEK’s previous generation, the CP-690 automated acuity projector does pretty much everything the brand new CP-770 does, however without the compact design, the LED illumination and the crazy-good line isolation features. We do however find it to be a competent projector, coming with 33 different charts standard, decent isolation/masking options, and duochrome capability (red/green over any chart). Its biggest drawback starts with mediocre contrast when compared with modern projectors and LCD screens. Doctors alike should still have no problem refracting with the light on or off, however, depending on room size and your set-up, it may be best to lower ambient light. The CP-690’s wireless remote is well thought out, however is rather large, and may be difficult to keep in the hand throughout the refraction

OUR TAKE: If you like acuity charts projected, the CP-690 does the job for less cash than most, although without the bells and whistles of newer models. Its halogen bulb will also need to be replaced on occasion although it does provide suitable (though not exceptional) contrast in most lightening scenarios.

Determination of Refractive State

when combined with other refractive instruments to determine the refractive state of a patient.

*based on CPT 92015 assuming determination of refractive state

#1. 33 Charts (+ Isolation)

Despite newer projectors being on the market- most of them posses the same acuity charts as this fella seen here. Manufacturers are always under pressure to produce more profits for their shareholders, and thus they sell newer devices that look cooler, sleeker, and work slightly (key word) better. The CP-690 offers nearly every chart that the newer CP-770 does, and maintains decent isolation options (per horizontal line). As far as acuity is concerned, it offers every character you’ll need to perform a refraction.

#2. Incredibly Robust

For it’s age, we were very impressed with both the CP-670’s and the CP-690’s robustness and technology. After selecting a chart, the projector’s spins dials immediately turn to your selected chart and it does so practically silently. Despite the wireless remote being infrared, the projector picked up on our selection even if it wasn’t pointed exactly at the machine mounted on the wall. The 690 even survived our 3 foot drop test.

No it does not. Since every room is different, we recommend getting a projector mount that suits your exam room best.

Yes, or close enough. Marco is still using infrared remotes, which requires you pointing it near the projector. This isn’t the end of the world though, as your exam room is probably tiny and you (with the remote) are already facing that direction anyway whilst refracting.

It’s decent, however since it utilizes halogen illumination, its LED competitors surpass it when evaluating clarity and contrast when displayed in the exam room.

Yes, very easy. Just grab a PD stick and measure the “20/200” letter using our acuity calibration guide as a reference.
