The McDonald laser optical zone marker is double‑ended with 6.5mm and 7mm cross‑hair etched circles, used to mark the optical zone on the cornea before excimer or femtosecond refractive ablation. The cross‑hairs center the ablation pattern on the visual axis, and the double‑ended design covers two common optical zone diameters in a single instrument.
