At six months, average visual outcomes did not differ between selected keratoconus eyes and controls. The sample was small, however, and repeat surgery occurred in both groups.
After ICL implantation, the biometer often misidentified the anterior chamber boundary. Even so, predicted refractive change remained within ±0.50 D for every formula.
Over 12 years at a high-volume center, 110 of 22,739 eyes underwent ICL exchange. Downsizing reliably reduced high vault, while the gain from upsizing diminished with age.
A systematic review of 38 studies compared AS-OCT- and UBM-based nomograms for ICL sizing and vault prediction. No approach performed consistently better across populations, devices and clinical settings.
