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)
Private Refractive Surgery Clinic, affiliated with an academic hospital
a prospective interventional case cohort in 37 eyes of 19 patients. In all eyes after standard phacoemulsification procedure, for either a cataract or a refractive lens procedure, the new multifocal IOL was implanted in the bag. The results in terms of uncorrected and corrected distance acuity (UCDA and CDA) and uncorrected near visual acuity (UNVA) at 40 and 60 cm were analyzed. Refractive parameters at 3 months were analyzed, as was the incidence of complications and halos. A historical comparison to other multifocal IOLs was done for the UCDA and UNVA at 40 cm, and the incidence of photopsias. The lenses compared were: apodized diffractive, hydrophilic (Seelens MF, Hanitalenses, Israel) and apodized diffractive hydrophobic (SN6AD1, Alcon, USA) lenses and a radially asymmetric refractive lens LS-312, Oculentis, Germany.
At three months postoperatively the mean UDVA was logMAR 0.01 + /- 0.11, with a CDVA of -0.06+/- 0.06. Mean UNVA at 40 cm was 0.08 + /- 0.08, and 0.27 +/- 0.12 at 60 cm. The mean postoperative spherical equivalent was +0.15D + 0.46 D with a range of -0.75 to +1.5D. Complaints of halos at 3 months occurred in 3 of 19 patients (15.8%). No complications other than a residual refractive error were seen. Compared to our historical data concerning the Seelens MF (Hanitalenses, Israel), the SN6AD1 (Restor +3, Alcon, USA), and the LS-312 MF30 (Oculentis MPlus), this lens performed well. The Seelens had a UDVA of 0.02 + 0.07 logMAR, the SN6AD1 0.04 + 0.09 logMAR, and the LS-312 0.04 + 0.15. The uncorrected near visual acuity at 40 cm was 0.09 + 0.12 with the Seelens MF, 0.08 + 0.09 with the SN6AD1, and 0.16 + 0.21 with the LS-312. Dysphotopsias and halos occurred in 15.8% with the BunnyLens, 12% with the Seelens MF, 18.1% with SN6AD1, and 18.89% with the LS-312. The differences are not clinically significant.
The BunnyLens MF hydrophilic apodized diffractive MFIOL performs well in this small prospective cohort at 3 months. Compared to historical data of other multifocal IOLs this lens is on par in terms of UDVA,UNVA, and occurrence of dysphotopsias. The hydrophilic apodized type of lenses seem to induce less halos and dysphotopsias, but this needs more study. No serious complications were seen, but longer follow-up is necessary.
