Visual function after monocular implantation of apodized diffractive multifocal or single-piece monofocal intraocular lens Randomized prospective comparison.

PURPOSE

To compare visual function after phacoemulsification with implantation of a multifocal intraocular lens (IOL) or a monofocal IOL.

SETTING

Department of Ophthalmology, Affiliated Hospital of Qingdao University Medical College, Qingdao, Shandong, China.

METHODS

This study comprised patients with unilateral cataract who had phacoemulsification with implantation of an AcrySof ReSTOR SA60D3 multifocal IOL (multifocal group) or an AcrySof SA60AT single-piece monofocal IOL (monofocal group). Postoperative visual function, including uncorrected (UDVA) and corrected (CDVA) distance visual acuity; uncorrected (UNVA), corrected (CNVA), and distance-corrected near visual acuity; and contrast sensitivity were evaluated 1 week, 1 month, and 6 months postoperatively. Patient-reported vision and spectacle independence in the 2 groups were also compared.

RESULTS

Of the 161 eyes, 72 were in the multifocal group and 89 were in the monofocal group. The multifocal group had statistically significant better UNVA than the monofocal group from 1 week postoperatively to the final follow-up and statistically significant better CNVA at 6 months (both P<.05). There were no statistically significant differences in UDVA or CDVA between the 2 groups over the 6-month follow-up. The multifocal group had statistically significantly better pseudoaccommodation than the monofocal group; the monofocal group had significantly better contrast sensitivity (both P<.05). Patients with the multifocal IOL reported being more satisfied than those with the monofocal IOL.

CONCLUSIONS

The multifocal IOL provided better near visual acuity and more spectacle independence than the monofocal IOL.
