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
25 patients (50 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), objective halometry (Aston halometer) and NEI-42 RQL-42 questionnaire were evaluated 3 months after surgery.
Results
None patient needed YAG-laser capsulotomy.
The mean binocular postoperative DCVA, UDVA, DCI80VA, UI80VA, DCI60VA, UI60VA, DCNVA and UCNVA were respectively -0.03, -0,01, 0.10, 0.10, 0.12, 0.14, 0.17, 0.14, logMAR. Binocular defocus curves showed visual performance higher than 0.10 logMar between +1.00 and -1,50D.
The mean HOA-RMS was 0.52 and the mean PSF was 0.46. Binocular contrast sensitivity was lowest in scotopic conditions at 18 cycles/degree. Halometry scores were homogeneous at 360° (1.21, 95%CI 1.20-1.22). The NEI RQL-42 evidenced high subjective satisfaction results for all the subscales, especially for far vision, activity limitations, dependence on correction, suboptimal correction, appearance and satisfaction with correction.
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.
