CONCLUSIONS

  • Effective and safe visual outcomes
  • Efficacy index of 1.11, safety index of 1.12
  • Exponential decay pattern decrease of ECD and the vault
  • No clinically important tendency found on ECD and IOL
  • 1.2 %/year decay rate of ECD
  • No important correlation between ECD and the vault
  • High vault not associated with accelerated ECD loss
  • No case of cataract formation
  • Possible protective effect of the central hole even in low vault
