Abstract Details

Purpose:

To evaluate and compare the objective and subjective outcomes between bilateral implantation of the extended depth of focus (EDOF) Mini Well intraocular lens (IOL) and the aspheric monofocal Mini-4-Ready IOL (both SIFI Medtech, Italy) in a cohort of myopic patients (axial length ≥ 26 mm).

Setting:

The study took place in the department of Ophthalmology of the University of Verona between May 2018 and December 2019 under the supervision of Professor Emilio Pedrotti, supervisor in charge of the surgical and medical cornea Unit.

Methods:

Prospective comparative study included 20 myopic patients (40 eyes with axial length ≥ 26 mm) bilaterally implanted with an EDOF Mini Well IOL (EDOF group) and 20 myopic patients (40 eyes with axial length ≥ 26 mm) bilaterally implanted with a Mini-4-Ready IOL (monofocal group). Three-month follow-up data included corrected and uncorrected distance visual acuity at 4 m and 80, 67, and 40 cm. De¬focus curves, objective contrast sensitivity, MTF cut-off, Strehl ratio and reading performance were measured. Subjective visual quality was evaluated based on National Eye Institute Refractive Error Quality of Life Instrument 42 (NEI RQL-42) scores.

Results:

Postoperative uncorrected distance visual acuity was 0,0 logMAR or better in 84% of patients of the EDOF group. Corrected monoc¬ular and binocular intermediate and near visual acuity was significantly better in the EDOF group (P < .001). De¬focus curve outcomes for myopic values were better in the EDOF group (P < .001). Halometric values were significantly better in the monofocal group (P < .05). Significantly better NEI RQL-42 subscale scores for near vision, far vision, activity limitations, glare, dependence on correction, and suboptimal correction were noted in the EDOF group (P < .05).

Conclusions:

Intermediate and near visual acuity was bet¬ter after EDOF IOL than after aspheric monofocal IOL implan-tation without sacrificing the distance visual acuity. Patients perceived a bigger improvement of their quality of life after the EDOF IOL implantation than after the monofocal counterpart.
