Purpose
To evaluate the safety of Vivity® (V®), Isopure® (I®) or Eyhance® (E®) IOLs, adopting a mini-monovision approach, in patients undergoing bilateral same-day cataract surgery
Setting
Single-center study at Vista Alpina Eye Clinic, Visp, Switzerland.
We here present a substudy within a double-blind, randomized, prospective trial where 280 eyes of 140 patients were bilaterally implanted with Vivity®, Isopure® or Eyhance®, targeting mini-monovision (-0.5D).
Methods
We compared the three IOLs based on four safety parameters, assessed between 4-6 months post-surgery:
- Monocular corrected distance visual acuity (CDVA)
- Binocular uncorrected distance visual acuity (bUDVA) under mesopic conditions
- Mesopic contrast sensitivity (CSV-100) at spatial frequencies of 3, 6, 12 and 18 cycles per degree
- Photic phenomena as reported in the McAlinden and NEI RQL-42 questionnaires
Results
CDVA was better for I® (-0.06±0.06 logMAR, p<0.001) and E® (-0.05±0.06, p=0.02) compared to V® (-0.01±0.11).
Mesopic bUDVA was best for E®, followed by I® (p=0.009) and V® (p<0.001): 0.11±0.08, 0.15±0.09, and 0.25±0.1 logMAR respectively.
Mesopic contrast sensitivity favored E® and I® over V®:
-at 12 cpd: V® 0.76±0.46 log units, I® 0.96±0.40 (p=0.011) and E® 1.01±0.41 (p=0.017).
-at 18 cpd: V® 0.26±0.26 log units, I® 0.42±0.33 (p=0.014) and E® 0.56±0.36 (p=0.002).
Photic phenomena occured in less than 10% of patients. Specifically, 97%, 95%, and 94% of patients with V®, I®, and E®, respectively, reported never or rarely experiencing glare (ns); 97%, 97%, and 100% never/rarely halos (ns); and 94%, 90%, and 97% (ns) never/rarely starbursts.
Conclusions
The findings underscore that all three Enhanced Depth-Of-Focus IOLs — Vivity®, Isopure®, and Eyhance® — maintain a strong safety profile, yet differences in visual acuity and contrast sensitivity especially under mesopic conditions suggest variations in their suitability for specific visual needs. These outcomes emphasize the importance of tailoring lens selection to individual patient needs and preferences in cataract surgery to optimize safety and visual outcomes.
