Visual And Refractive Clinical Outcomes Of Extended Depth-Of-Focus Toric Intraocular Lens

Purpose: To compare the visual and refractive outcomes with a diffractive toric extended depth-of-focus (EDOF) intraocular lens (IOL) when both eyes are targeted for emmetropia and the nondominant eye is targeted for slight myopia

Patients having routine cataract surgery with bilateral Alcon  IQ Vivity toric EDOF IOL implantation were assigned to 1 of 2 groups

Methods:. In 1 group, the nondominant eye was targeted for -0.75 diopter (D) (monovision). Assessments included uncorrected monocular and binocular visual acuities  at distance (4 m), intermediate (66 cm), and near (33 cm) and the postoperative residual refractive error.

Results: Twentyfive patients were enrolled in each group. The mean residual refractive astigmatism was 0.50 D or lower in 92% of eyes in the mini-monovision group and 95% of eyes in the emmetropia group 3 months postoperatively. The monovision group had slightly worse uncorrected visual acuity at 4 m than the emmetropia group (0.14 versus 0.09; P = .002) but better uncorrected acuity at 33 cm (0.20 versus 0.34; P < .001). Binocular uncorrected acuity was not statistically significantly different between groups at 4 m (-0.04 versus -0.01; P = .33) or 66 cm (0.05 versus 0.03; P = .34) but was statistically significant at 33 cm (0.26 versus 0.18; P = .03)

Conclusions: The EDOF toric IOL provided functional distance, intermediate, and near vision. A slight monovision approach appears to improve near visual acuity.
