In a 311-eye series, IOL position and refraction remained stable when optic capture persisted, but capsular block syndrome was recorded in 71.7% of eyes.
In a randomized study of 56 eyes, sulcus placement with optic capture after a capsular tension ring produced a more myopic result than standard in-the-bag implantation.
In a retrospective series of 169 eyes, a formula combining the original IOL, biometry and manifest refraction predicted lens-exchange outcomes more accurately than Barrett Rx.
