Clinical outcomes of plate-haptic diffractive multifocal toric IOL in cataract eyes with long axial length and corneal astigmatism

The prospective study is aimed to determine the clinical outcomes of plate-haptic diffractive multifocal toric intraocular lens (IOL) implantation in cataract patients with long axial length and corneal astigmatism. Visual outcomes, defocus curves, contrast sensitivity, rotational stability, vector changes of refractive astigmatism and patient satisfaction were assessed over 3 months. Vector analysis was performed by the Alpins method. A total of 36 eyes (18 patients) underwent cataract surgery with implantation of AT LISA toric 909 M multifocal toric IOL. Preoperatively, mean axial length AL was 27.31 ± 2.20 mm. Mean manifest sphere and cylinder were - 6.66 ± 5.37 diopter (D) and - 1.88 ± 1.11 D. Postoperatively, mean manifest sphere and cylinder were reduced to 0.13 ± 0.23 D and - 0.29 ± 0.32 D, respectively (P < 0.05, Wilcoxon test). Mean uncorrected distance and near visual acuities (logMAR) were 0.40 ± 0.10 and 0.19 ± 0.16, respectively. At 3 months, 91.7% of patients showed IOL rotation of less than 5 degrees. The difference vector was 0.34 ± 0.26 D, for a correction index of 0.93 ± 0.40 at 3 months. In summary, plate-haptic diffractive multifocal toric IOL improves distance and near visual functions and reduces refractive astigmatism in cataract patients with long axial length and corneal astigmatism.Trial registration: NCT04833491.
