Description
Monteiro and colleagues checked eye-measuring machines in patients with implanted helper lenses, in this 2026 research letter from Porto, Portugal. Two modern biometers map the eye's inner surfaces automatically before cataract surgery. An extra lens inside the eye, placed earlier to correct vision, can confuse that mapping, so the team reviewed one hundred such eyes.
Both devices misdrew the eye's surfaces in roughly a quarter of eyes, mistaking the implanted lens for the natural one. Errors shrank the measured chamber depth and inflated lens thickness, and one lens style caused most mistakes. One machine sometimes refused to guess, forcing manual checks. The authors warn surgeons to inspect every scan in these eyes.
