and Dr. van der Meulen have no interest to disclose.
Purpose
• To report the outcomes in terms of visual acuity,
refraction, incidence of halos at 3 months after
implantation with a new 4 loop haptic apodized
diffractive hydrophilic multifocal IOL (MFIOL), the
BunnyLens (Hanitalenses, Israel)
Methods:
•Prospective interventional case cohort
•Standard phacoemulsification 2.2 mm incision, either
for cataract or refractive lens exchange.
•Outcome measures: uncorrected and corrected
distance acuity, uncorrected near acuity, incidence of
halos, historical comparison with cohorts of apodized
diffractive hydrophilic lenses, (SeeLens MF,
Hanitalenses, Israel) apodized diffractive hydrophobic
lens (SN6AD1, ReSTOR, Alcon), and a radially
asymmetric refractive IOL (LS-312 , Mplus lens,
Oculentis, Germany)

Conclusion:
1. The BunnyLens MF (Hanita Lenses, Israel)
performs well in a small prospective cohort.
2. The IOL performs on par with historical data of
other lenses, like the SeeLens MF (Hanita
Lenses), the SN6AD1 (Restor, Alcon, USA),
and the LS-312 (Mplus, Oculentis, Germany
3. The hydrophilic apodized diffractive type of
IOL seems to induce less dysphotopsias, but
more study is needed to confirm this.
