Abstract Details

Purpose:

To evaluate the visual outcome after cataract surgery with bilateral implantation of a diffractive - refractive (hybrid) multifocal intraocular lens (MFIOL).

Setting:

Parc de Salut Mar, Universidad Pompeu-Fabra - Autónoma, Barcelona, Spain and Institut Català de Retina, Barcelona, Spain.

Methods:

Consecutive patients with bilateral cataract were included. Phacoemulsification with bilateral implant MFIOL Optivis™ (Aaren Scientific) was performed by the same surgeon and under the same conditions. Over a 3-month follow-up, the main outcome measures were uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity at 60 cm (UIVA), distance-corrected intermediate visual acuity (DCIVA), uncorrected near visual acuity at 33 cm (VNVA), distance-corrected near visual acuity (DCNVA), spherical equivalent (SE), contrast sensitivity (CS), presence of dysphotopsia, use of spectacles and patient satisfaction with the test V -14.

Results:

32 patients were included. SE of ±0.5 diopter (D) and of ±1.0D was achieved in 77% and in 94% of patients, respectively. The mean values at 3 months improved significantly: UDVA in logMAR 0.13±0.12 (p <0.001), DCVA 0.07 ± 0.07 (p <0.001), UIVA 0.32 ± 0.18 (p <0.001), DCIVA 0.17 ± 0.13 (p <0.001), UNVA 0.23 ± 0.18 (p <0.001) and DCNVA 0.04 ± 0.06 (p <0.001). The patients achieved spectacle independence and good visual function measured with VF-14 (89.3 ± 11.1). Significant improvement in CS was observed and there was no significant difference in dysphotopsia postoperatively.

Conclusions:

The hybrid multifocal lenses provided good visual results in the near and far distance, while in the intermediate distance the results were not so satisfactory. The predictability of the refractive outcome was excellent. Patients were satisfied as they achieved spectacle independence and did not suffer from increased dysphotopsia, although CS was particularly affected at frequencies 12 and 18 when compared to monofocal lenses.
