Measurements of the globe were made at different stages of accommodation with Kretz A‐mode ultrasonic equipment. A comparison between the movement of the crystalline lens in two refractive groups appeared to show that the highly myopic lens had to expand more per dioptre of accommodation; in other words, it was less efficient than the near‐emmetropic lens. Also the posterior surface of the lens appeared to move more in highly myopic eyes than in near‐emmetropic eyes.
