Laser lithotripsy requires urologists to wear laser eye protection.
Laser eye protection devices screen out specific light wavelengths and may distort color perception.
This study tests whether urologists risk color confusion when wearing laser eye protection devices for laser lithotripsy.
Urologists were tested with the Farnsworth Dichotomous Test for Color Blindness (D-15) and the Farnsworth-Munsell 100-Hue Test (FM-100) without (control) and with laser eye protection devices for coumarin green, alexandrite and holmium : YAG lasers.
Error scores were tabulated.
The pattern of color deficits was characterized with confusion angles, confusion index (C-index), scatter index (S-index) and color axes.
Laser eye protection devices were tested with spectrophotometry for spectral transmittance and optical density.
The D-15 transposition errors (mean plus or minus standard deviation) for control, holmium : YAG, alexandrite and coumarin green laser eye protection were 0 ± 0,0 ± 0,0.3 ± 0.5 and 6A ± 1.6, respectively (p=0.0000001).
The FM-100 error scores (mean plus or minus standard deviation) were 20 ± 15,20 ± 14,91 ± 32 and 319 ± 69, respectively (p=0.0001).
The confusion index scores indicated a mild color confusion for the alexandrite and pronounced color confusion for the coumarin green laser eye protection. (...)
