Accuracy of intraocular lens calculation formulas in aphakic eyes undergoing simultaneous silicone oil removal and intraocular lens implantation

Key Points

• This research aims to evaluate the accuracy of intraocular lens (IOL) calculation formulas in aphakic eyes undergoing simultaneous silicone oil removal and IOL implantation.
• Analysis of calculation formulas for IOLs in aphakic eyes
• Comparison of new-generation formulas against traditional ones
• Adjustment using the 'Rule of 9s' for sulcus placement
• New-generation IOL calculation formulas showed improved accuracy and precision
• The 'Rule of 9s' adjustment optimized outcomes for sulcus-placed IOLs
• Higher overall trueness observed with newer formulas compared to previous methods
