Effect of plateau iris configuration on effective lens position and intraocular lens power calculation: Report of 3 cases

We report the cases of 3 patients with plateau iris configuration who had bilateral phacoemulsification with posterior chamber intraocular lens (IOL) implantation. A standard IOL power formula—Holladay 2 or Hoffer Q—was used to select IOL power preoperatively to achieve emmetropic refractive outcomes. The surgeries were uneventful, but the postoperative outcomes were more myopic than calculated, deviating from the preoperative targets by −0.550 to −1.175 diopters. To counteract this effect in 2 of the eyes, the IOL power was adjusted to a more hyperopic target, resulting in the desired emmetropic outcome.
