Description
Yvonne Nowosielski and co-authors compare four formulas for picking lens power in a tricky eye surgery, reporting in 2026. When a replacement lens must be stitched to the eye wall with the Yamane method, standard power math may drift. The team checked which formula lands closest to the target focus.
Records covered 59 eyes treated between March 2019 and April 2024. All four formulas, EVO 2.0, Barrett, SRK/T, and Hoffer Q, erred slightly toward near sight. EVO 2.0 had the lowest average error, with Barrett close behind. No gap between formulas reached statistical weight, though. Surgeons can treat the leading formulas as near equals for this fixation method, with EVO holding a slight edge.
