Purpose
To assess the visual performance in terms of quality of vision and visual outcomes after bilateral implantation of extended monofocal intraocular lens (IOL).
Setting
The study was carried out at the Ophthalmic Unit of the University Hospital of Verona, Italy.
Methods
20 patients (40 eyes) underwent bilateral implantation of the extended monofocal intraocular lens (Evolux-Sifi - IT). Patients with bilateral cataracts, preoperative corneal astigmatism lower than 1 Diopter and no other concomitant ocular diseases were included. Patients with intraoperative complications were excluded from the analysis.
Distance corrected and uncorrected visual acuities at 4 meters, 80, 60, and 33 centimeters (DCVA, UDVA, DCI80VA, UI80VA, DCI60VA, UI60VA, DCNVA, UNVA), binocular distance corrected defocus curve, contrast sensitivity, high order optical aberrations (HOA) (Root mean square- RMS) and NEI-42 RQL-42 questionnaire were evaluated 3 months after surgery.
Results
The mean monocular postoperative DCVA, UDVA, DCI80VA, UI80VA, DCI60VA, UI60VA, DCNVA and UCNVA were respectively -0.02±0.09, 0.05±0.12, 0.18±0.11, 0.18±0.12, 0.23±0.14, 0.22±0.13, 0.33±0.16 and 0.33±0.16 logMAR. Binocular defocus curves showed visual performance higher than 0.10 logMar between +1.00 and -1,50D.
The mean HOA-RMS was 0.20±0,14 and the mean PSF was 0.46±0,12. Overall, binocular contrast sensitivity was lower in scotopic conditions. The NEI RQL-42 evidenced high subjective satisfaction results for all the subscales, especially for activity limitations, clarity of vision, far vision, dependence on correction, suboptimal correction, appearance and satisfaction with correction.
No patient needed YAG-laser capsulotomy.
Conclusions
Evolux IOLs demonstrated a good safety profile and excellent visual performances at all distances, with good contrast sensitivity and high satisfaction in both objective and subjective high quality of vision.
