Purpose

The purpose of this study was to evaluate astigmatism correction, rotational stability, overall patient satisfaction, spectacle independence, and binocular visual acuity, after bilateral toric extended depth of focus intraocular lens (EDOF IOL) Mini Well implantation targeted for emmetropia in patients with bilateral corneal regular astigmatism between 0,75 D and 2,70 D.

Setting

The study was carried out at the Ophthalmic Unit of the University Hospital of Verona, Italy.

Methods

This prospective study included 20 astigmatic patients (40 eyes) bilaterally implanted with EDOF toric Mini Well IOL. Three-months follow-up data included corrected and uncorrected distance visual acuity at 4 m and 80, 67, and 40 cm. IOL stability evaluation after dilation, binocular defocus curves, subjective and objective contrast sensitivity(CS), and objective optical quality (Optical Quality Analysis System [OQAS]; Visiometrics SL, Terrassa, Spain), halometry, reading performance and the presence of posterior capsular opacity (PCO) were measured. Subjective visual quality was evaluated based on National Eye Institute Refractive Error Quality of Life Instrument 42 (NEI RQL-42) scores.

Results

The mean residual cylinder was -0.17±0.39 D and within 0,25D or 0,50D in 62,5% and 87,5% of cases respectively. None of the patients needed additional surgery. 80% of patients were subjectively spectacle independent and 55% were fully satisfied. Monocular UDVA, UI80VA, UI67VA, UNVA of 0.2 logMAR or better was found respectievely in 77,5%, 87,5%, 77,5% and 72,5% of eyes. Monocular CDVA, DCI80VA, DCI67VA, DCNVA of 0.1 logMAR or better was found respectievely in 100%, 90%, 60% and 65% of eyes. Binocular results were slighly better. Strehl, MTF cut off, ocular root mean square, reading speed were respectively 0.26±0.28, 19.82±12.35, 0.31±0.17, 125,4±27.21. Halometry was homogeneous in all quadrants, CS was higher in photopic conditions.

Conclusions

The Toric MiniWell EDOF IOL proved to be safe since none of the patient experienced clinically significant IOL decentration nor developped PCO. This IOL showed rotational stability and reliable astigmatic correction, it also guaranteed spectacle independence and patient satisfaction without undermining binocular visual acuity.
