Purpose
To assess the visual performance in terms of quality of vision and visual outcomes after bilateral implantation of extended monofocal intraocular lens (IOL) with an emmetropic target.
Setting
Ophthalmology Clinic, Department of Surgery, Dentistry, Maternity and Infant, University of Verona, 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) and NEI-42 RQL-42 questionnaire were evaluated 3 months after surgery.
Results
No patient required YAG-laser capsulotomy. The mean monocular postoperative DCVA, UDVA, DCI80VA, UI80VA, DCI60VA, UI60VA, DCNVA, and UCNVA were -0.05±0.08, 0.02±0.09, 0.19±0.14, 0.2±0.13, 0.23±0.15, 0.23±0.14, 0.31±0.16, and 0.35±0.15 logMAR. Binocular defocus curves showed visual acuity better than 0.10 logMAR between +1.00 and -1.50D. The mean HOA-RMS was 0.52, and PSF was 0.46. Contrast sensitivity was lowest in scotopic conditions at 18 cycles/degree. The NEI RQL-42 questionnaire showed high subjective satisfaction, particularly regarding activity limitations, clarity of vision, far vision, dependence on correction, 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.
