Purpose

To evaluate DRP of patients bilaterally implanted with a diffractive MF-IOLs, PanOptix®.

Setting

Cataract surgery with multifocal intraocular lenses (MF-IOLs) is a common presbyopic correction with promising outcomes. Digital devices have become an essential part of the modern human lifestyle. Digital reading performance (DRP) is different from conventional paper reading in many ways, for example display polarity. We conduct this study to evaluate DRP and propose the optimized critical-print-size (CPS) and screen polarity recommendation for MF-IOLs implanted patients.

Methods

Fifty-four eyes (26 participants) of bilateral MF-IOLs implantation, on the same day. The primary outcome is binocular uncorrected reading acuity measure with MNREAD® iPad App at 3 months postoperatively. Secondary outcomes included distance binocular uncorrected visual acuity (BUCVA), intermediate (60 cm) BUCVA, near (40 cm) BUCVA at post-operative at day 1, 1 week, and 1 month, CPS with uncorrected acuity (60cm and 40 cm) at 3 months on MNREAD® iPad App.

Results

LogMAR BUCVA measure with MNREAD® iPad App at 3 months at 60 and 40 cm with positive display polarity (black-on-white background) and negative polarity (white-on-black) are -0.12, -0.09, -0.01, and 0.15, respectively. The mean digital CPS at 40 cm is 0.24.

Conclusions

Bilaterally implanted PanOptix®, shown rapid visual recovery and excellent DRP at 60 cm and 40 cm. The setting of a display screen on the digital device(s) to a positive display polarity (black-on-white) with a font size of 7 pt or larger increases the likelihood of digital reading satisfaction in bilaterally implanted in bilateral implanted MF-IOLs.
