Abstract Details

Purpose:

To observe the early vision quality of phacoemulsification cataract surgery with implantation of refractive rotationally asymmetric multifocal intraocular lens (IOL).

Setting:

A self-controlled, before-after trial.

Methods:

A self-controlled, before-after trial in which 36 patients (40 eyes) underwent phacoemulsification cataract surgery combined with the refractive rotationally asymmetric multifocal IOL implantation in Wuhan Aier eye hospital. Uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA) and corrected distance visual acuity (CDVA), the postoperative spherical equivalent (SE), defocus curve and transfer modulation function (MTF), intraocular high-order aberrations, visual function index of life quality and the rate of spectacle independence were evaluated 3 months postoperatively.

Results:

At 3 months, significant improvement in UDVA, CDVA, UIVA, and UNVA were found postoperatively (P < 0.05). The defocus curve showed two peaks of maximum visual acuity (0 and -2.5 D of defocus) and the visual acuity of +1.0 D~-4.0 D defocus were better than 0.25 LogMAR. The MTF was significantly improved (P<0.05); improvement in total intraocular aberrations, vertical coma, and vertical trefoil were observed (P<0.05). The median score of Chinese version visual function index-12 (VF-12-CN) was 1.0 (0.0, 2.0) at 3 months. 92.5% of the patients were completely spectacle independent for far and near vision.

Conclusions:

Refractive rotationally asymmetric multifocal intraocular IOL provided satisfying visual acuity for far and near with a good range of intermediate vision. Patients had good visual quality and high quality of life.
