| Popis: | To report refractive outcomes of scleral-fixated intraocular lens (IOL) implantation with Gore-Tex (W.L. GoreAssociates, Newark, DE) suture and combined pars plana vitrectomy and compare predicted refractive outcomes among 5 IOL power calculation formulas.Retrospective case series.Patients undergoing scleral-fixated IOL implantation with Gore-Tex suture at our institution between January 2015 and June 2018.Comparison of preoperative biometrics with postoperative refraction and calculation of predicted refractive outcome with 5 different IOL formulas.Prediction error and absolute error to compare postoperative refraction with refraction predicted by lens power calculation formulas.Thirty-one eyes of 31 patients were included. All power calculations assumed in-the-bag position of the IOL. The Akreos A060 (BauschLomb, Rochester, NY) was implanted in 23 eyes and the CZ70BD (Alcon, Fort Worth, TX) in 8 eyes, and all lenses were sutured 3 mm behind the limbus. Average postoperative spherical equivalent (SE) was -0.79±0.95 diopters (D). Average prediction error (postoperative SE refraction minus target refraction) was -0.19±0.72 D. Postoperative SE was within 1.0 D of target in 25 of 31 patients (81%) and 2.0 D of target in 31 of 31 patients (100%). The repeated-measures analysis of variance of absolute error by lens power formula was significant (P = 0.012), with Haigis demonstrating greater error. There was no significant difference among Barrett II, Sanders-Retzlaff-Kraff theoretical (SRK/T), Holladay 2, or Hoffer Q.For eyes undergoing pars plana vitrectomy with scleral-sutured IOL implantation, assumption of in-the-bag IOL position when calculating lens power leads to acceptable refractive outcomes. Barrett II, SRK/T, Holladay 2, and Hoffer Q formulas were noninferior to each other. |
