Toric Aberrometric Extended Depth Of Focus Intraocular Lens: Visual Outcomes, Rotational Stability, Patients’ Satisfaction, And Spectacle Independence.

To evaluate visual outcomes, rotational stability, patients’ satisfaction and spectacle independence after bilateral toric extended depth of focus intraocular lens (EDOF IOL) implantation.

Prospective observational study including 20 cataract-patients with bilateral corneal astigmatism between 0.75 and 4.50 D implanted with toric EDOF IOL. Three-month follow-up included: distance corrected and uncorrected visual acuity at 4m (DCVA and UDVA), 80cm (DCI80VA and UI80VA), 67cm, (DCI67VA and UI67VA) and 40cm (DCNVA and UNVA), IOL stability, binocular defocus curves, contrast sensitivity (CS), halometry, reading performance and subjective and objective (Root mean square -RMS, modulation transfer function -MTF- cut off and point-spread-function -PSF- Strehl ratio) visual quality.

Mean refractive spherical equivalent and residual cylinder were -0.21±0.74 D and 0.29±0.31 D, respectively. No patients needed additional surgery due to IOL rotation. Binocular UDVA, UI80VA, UI67VA and UNVA ≥0.2 logMAR was found in 85%, 95%, 85% and 80%. The DCVA showed higher performances. All visual acuities at defocus curves were ≥0.12 D between +0.50 and -2.00. PSF Strehl ratio, MTF cut off, RMS were 0.26±0.28, 19.82±12.35, 0.31±0.17. Reading analysis reached 125.4±27.21, 92.56±7.82, 0.17±0.15 and 0.50±0.11 for mean reading speed, visual acuity score, reading acuity and critical print size respectively. CS was higher in photopic conditions. Subjective spectacle independence was achieved in 80% of patients and 55% were fully satisfied.

Toric EDOF IOL showed rotational stability and reliable astigmatic correction. It provided spectacle independence and good performance from distance to near distance, reaching high patient satisfaction without undermining binocular quality of vision.
