Objective:

To evaluate the performance of modern IOL power calculation formulas for two PARTIAL-RoF extend IOL models and assess the efficacy of a novel constant optimization method, which needs further clarification.

Key Findings:
  • Modern IOL power calculation formulas demonstrated satisfactory predictive accuracy, indicating their reliability in clinical settings.
  • The TVO method showed potential for improving IOL power calculation accuracy, suggesting a need for further exploration.
  • Variability in refractive outcomes was observed between the two IOL models, highlighting the importance of tailored approaches.
Interpretation:

The study highlights the importance of precise IOL power calculations for achieving optimal visual outcomes, particularly with advanced IOL designs, and suggests implications for current practices.

Limitations:
  • Retrospective design may introduce bias, which could affect the reliability of the findings.
  • Limited sample size for each IOL model may affect generalizability, necessitating caution in applying results.
Conclusion:

The findings support the need for further validation of the TVO method and emphasize the significance of accurate IOL power calculations in enhancing patient visual outcomes, in light of existing literature.
