Purpose
The aim of our study is to evaluate the quality of vision after bilateral Vivity or Vivity toric non-diffractive EDOF IOLs implantation in Taiwanese patients.
Setting
Prospective, single arm study.
Methods
Our study was a prospective, non-interventional single arm study. The inclusion criteria for this study was cataract patients who had undergone bilateral uncomplicated cataract removal and Vivity/toric IOL implantations.
Outcomes measurement include binocular uncorrected and corrected far, intermediate (66cm) and near (40cm) visual acuity; visual quality measurement including International Reading Speed Test (IReST), Questionnaire for Visual Disturbances (QUVID), and Intraocular Lens Satisfaction (IOLSAT) questionnaire were performed before and after surgery for 3 months.
Results
There were 84 patients and 168 eyes included, mean age was 61.8±8.4 years old, with female predominance (58.3%).
At three months, the uncorrected binocular far, intermediate and near visual acuity were 0.04±0.06, 0.12±0.14 and 0.25±0.16 logMAR, respectively. Corrected binocular far visual acuity was 0.02±0.05 logMAR, while intermediate and near visual acuity were 0.08±0.14 and 0.14±0.14 logMAR.
The postoperative reading speed was significantly improved compared to preoperative reading speed. (P<0.05).
IOLSAT reveals most patients are well-adapted without glasses under various light conditions and different distance. QUVID shows mild dysphotopsia, with starburst may be the only noticeable visual disturbance (32.4% in frequency and severity).
Conclusions
Vivity or Vivity toric IOL could achieve good far and intermediate vision, with acceptable near visual acuity For possible photopic problems, there were 67.6% to 86.8% reported no starburst, halos, or glare after cataract surgery..
