Abstract

Purpose.

To evaluate the visual performance of patients with high myopia with diffractive multifocal intraocular lens (MIOL) as compared with aspheric monofocal intraocular lens (IOL).

Methods.

A prospective nonrandomized controlled study was conducted. Consecutively, 36 patients with senile cataract (72 eyes) received phacoemulsification and IOL implantation: 12 patients (24 eyes) were implanted with AcrySof IQ ReSTOR SN6AD3 IOL, 12 patients (24 eyes) were implanted with AcrySof IQ ReSTOR SN6AD1 IOL, and another 12 patients (24 eyes) were implanted with AcrySof IQ SN60WF as control group. All patients were assessed at 6 months postoperatively in these aspects: uncorrected and best-corrected visual acuities for distance (5 mo), intermediate (60 cm), and near (30 cm), modulation transfer function, and defocus curve. Patient satisfaction (spectacle independence, glare or halo disturbance, and overall satisfaction) was assessed by a questionnaire.

Results.

At 6 months postoperatively, both uncorrected and distance-corrected intermediate and near visual acuity were significantly better in multifocal groups than the control monofocal group (p<0.01). Intermediate visual acuity in the SN6AD1 group was a little higher than that in the SN6AD3 group (p<0.05); conversely, the near visual acuity in the SN6AD3 group was better than in the SN6AD1 group (p<0.05). Modulation transfer function with a 5.0-mm aperture was similar in the 3 groups and there was no statistically significant difference. Patients in both multifocal groups reported excellent overall spectacle independence and satisfaction with the IOLs.

Conclusions.

Compared with aspheric monofocal IOL, AcrySof ReSTOR IQ multifocal IOLs could provide a functional vision range from near to distance, resulting in high level of spectacle independence and satisfaction among patients with high myopia.
