Purpose
To analyze the objective and subjective visual performances of a new hybrid refractive/aspheric extended depth of focus (EDOF) intraocular lens (IOL).
Setting
Ophthalmology Clinic, Department of Neurosciences, Biomedicine and Movement Sciences, University of Verona, Verona, Italy
Methods
In this monocentric prospective study patients with bilateral cataracts underwent cataract surgery and were implanted with a Lucidis IOL (SAV-IOL SA, Neuchâtel, Switzerland) in both eyes, 1 week apart from each other. At 3 months from implantation postoperative evaluations included monocular and binocular uncorrected and distance-corrected distant (4 m), intermediate (80 cm, 67 cm) and near (40 cm) visual acuities (UDVA/DCVA, UI80-67VA/DCI80-67VA, UNVA/DCNVA), binocular defocus curves, halometry, contrast sensitivity and objective quality-of-vision measurements. Also, patients were also asked to complete the national eye institute refractive error quality of life (NEI-RQL-42) questionnaire.
Results
Twenty-five patients (50 eyes) were included. The mean postoperative binocular UDVA, UI80VA, UI67VA and UNVA were- 0.02 ± 0.13, 0.05 ± 0.09, 0.05 ± 0.08 and 0.03 ± 0.1 LogMar, and did not significantly differ from their corrected counterparts. On binocular defocus curves a VA ≥0.05LogMar was found between +0.50 and − 2.50 D of vergence, whereas the mean distance from the central stimulus on halometry was 1.23 ± 0.01. Mean ocular and corneal radical mean square at 4 mm were 0.31 ± 0.28 and 0.19 ± 0.07, respectively; whereas the mean Strehl ratio was 0.2 ± 0.09.
Conclusion
Lucidis IOLs demonstrated excellent visual performances, especially at close distances while maintain good quality of vision, contrast sensitivity, and overall patient-satisfaction.
