IOL calculation for Yamane fixation: four formulas and a myopic shift

Cataract IOL Barrett Universal II IOL calculation Yamane technique EVO formula Secondary scleral fixation Yamane biometry Secondary IOL Scleral IOL fixation

In 59 eyes after secondary Yamane fixation, EVO, Barrett, Hoffer Q and SRK/T did not differ in accuracy; every formula showed directional myopic prediction error.

Yamane or four-point IOL fixation: speed versus redislocation risk

Cataract IOL Yamane technique Four-point IOL fixation IOL redislocation Surgical complications Scleral IOL fixation

In a retrospective cohort of 179 eyes, Yamane fixation shortened surgery by about 14 minutes but was associated with a higher hazard of IOL redislocation.

IOL calculation for Yamane fixation: findings from a network meta-analysis

Cataract IOL IOL power calculation Scleral-fixated IOL Yamane technique

A network meta-analysis of 9 studies and 399 eyes compared 7 formulas for flanged intrascleral IOL fixation. Barrett Universal II ranked consistently well, but no formula showed statistically significant superiority.
