| Popis: | Purpose To compare the refractive accuracy of intraocular lens (IOL) power calculations between patients with vitreomacular interface disorders who had phacovitrectomy for vitreomacular traction (VMT), epiretinal membranes (ERM), and macular holes. Setting Baskent University Department of Ophthalmology, Ankara, Turkey. Design Retrospective case series. Methods Refraction results 8 weeks postoperatively were compared between phacovitrectomy (3 study groups comprising eyes with VMT with intrafoveal pseudocysts, ERM, or medium-to-large macular holes) and phacoemulsification (control group comprising eyes having phacoemulsification only). The IOLMaster 700 partial coherence interferometry (PCI) device and Haigis formula were used for all calculations. Results This study included 100 eyes (100 patients), 25 in each of the 4 groups. There was no statistically significant difference in axial length (AL) between the groups ( P = .305). Differences in the preoperative macular thickness were statistically significant between all groups except between the macular hole and VMT groups. Most eyes (92%) in the VMT and macular hole groups and all eyes in the VMT and phacoemulsification groups achieved a final refraction within ±1.00 diopter of the refractive aim. The mean prediction error and the mean absolute error did not differ significantly between the groups. In all groups, there was no significant correlation between prediction error and age, AL, preoperative refractive error, or preoperative or postoperative macular thickness ( P > .05). Conclusions The IOL power calculation with PCI yielded no difference in postoperative refraction errors between the vitreomacular interface disorders. There was no correlation with preoperative refraction, age, or preoperative or postoperative macular thickness. |
