Abstract Details

Purpose:

To compare the visual outcome and subjective visual symptoms in patients after implantation of the AcrySof ReSTOR SN6AD1 multifocal intraocular lens (IOL) and after implantation of the AcrySof SA60AT spherical monofocal IOL and Akreos АО aspheric monofocal IOL in cataract surgery.

Setting:

Department of Ophthalmology, Saint Petersburg State Medical University, Saint-Petersburg, Russia.

Methods:

34 patients had SN6AD1 multifocal (group 1, 48 eyes), 19 patients had Akreos АО monofocal aspheric (group 2, 30 eyes) and 13 patients had AcrySof SA60AT monofocal spherical (group 3, 18 eyes) IOL implantations. Patients with multifocal IOL were closely paired in age, sex, and ocular findings with patients who had monofocal IOL implantation. Six months postoperatively uncorrected/corrected distance visual acuity (UDVA/CDVA), uncorrected intermediate (60 cm) and near (33 cm) visual acuity (UNVA), the defocus curve, contrast sensitivity and a quality-of-life questionnaire were evaluated. Furthermore, independence from glasses and the presence of optical phenomena were assessed.

Results:

Group 2 had statistically better UDVA than the group 1 (P=0.04). There was no significant difference in the mean uncorrected intermediate and best corrected distance visual acuities between the groups. UNVA was better in group 1 than in groups 2, 3 (p<0.0001). Photopic contrast sensitivity for high spatial frequencies was better for the groups 2 and 3. Halos occurred in 44.1% of patients (group 1) and in 5.3% (group 2) (p=0.007). No patient reported glare. Spectacle independence rate was significantly better in the group 1 (88.2%) than in the groups 2 (5.3%) and 3 (7.7%) (p˂0.0001).

Conclusions:

Multifocal IOLs provided higher spectacle independence and satisfactory functional vision over a broad range of distances but were associated with increased halos, reduced photopic contrast sensitivity for high spatial frequencies and distance visual quality compared with the monofocal IOLs.
