I found some experimental data from other people with aphakia: https://sci-hub.se/https://doi.org/10.1016/0042-6989(92)90166-g https://sci-hub.se/https://doi.org/10.1016/0042-6989(92)9016... ("Scotopic spectral sensitivity of phakic and aphakic observers extending into the near ultraviolet") It looks like it's basically the entire ~315-420nm range. And, we normal/phakic people are technically sensitive to all of those wavelengths too—they're just very heavily, not completely, attenuated by lens absorption. Your relative sensitivity is greater by a factor of maybe 10,000, at 350 nm.
