Which capsular tension ring size for axial length ≥30 mm?

Cataract IOL Capsular tension ring High myopia Long eyes Large capsular tension ring Capsular apposition IOL tilt Posterior capsule opacification Clinical trials IOL decentration

In a 120-eye trial, the 13×11 mm ring better stabilized the IOL and more often achieved posterior capsule contact, but study power was only 61%.

IOL calculation after capsular tension ring implantation: four formulas

Cataract IOL Zonular weakness Capsular tension ring Barrett Universal II IOL calculation Formula validation ARGOS biometry Holladay II Pseudoexfoliation

In 98 eyes with a capsular tension ring, Barrett Universal II and Holladay II had lower absolute error, but all four formulas showed a mild hyperopic shift.

Optic capture in pseudoexfoliation: the risk of a myopic shift

Cataract IOL Phacoemulsification Capsular tension ring Pseudoexfoliation IOL optic capture

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.
