Abstract Details

Purpose:

To assess the visual and refractive outcome of a new presbyopia-correcting multifocal intraocular lens (IOL) (Technis Symfony Extended Range of Vision IOL, Abbott Medical Optics).

Setting:

Optimax Laser Eye Clinic, Newton Abbott in United Kingdom

Methods:

This was a retrospective analysis of 36 eyes of 19 patients operated by a single surgeon (JM) in a single centre. Symfony non-toric IOL was implanted in 25 eyes and Symfony toric in 11 eyes. All patients did not have previous corneal excimer laser treatment and had healthy maculae. The mean age of patients was 59.7 years (range 45 to 71). The uncorrected distance visual acuity (UDVA), uncorrected near visual acuity (UNVA) and postop refraction were measured at 1 week, 1 month and 3 months.

Results:

Full visual and refractive data was available for all patients at 7 weeks postoperatively. 86% of eyes achieved UDVA of 20/30 or better and 36% of eyes could see 20/20 or better. Postoperative mean UDVA was 0.84 (range 0.6 to 1.2) and postoperative mean sphere and mean cylinder were +0.52 dioptres (D) (range: -0.75 to +1.25) & -0.53 D (range: 0 to -1.25) respectively. 60.5% of eyes achieved UNVA of N8 or better and 38.3% of eyes could see N6 or better. UNVA of N10 or worse was evident in 39.5% of eyes.

Conclusions:

Our early results indicate that the Symfony multifocal IOL offers satisfactory functioning distance vision in the majority of patients but for attaining clearer near vision for small print, the outcome is substantially suboptimal and cause for concern. A better understanding of the uncorrected defocus curve and its relationship to postoperative refractive aim may facilitate optimal visual outcomes for uncorrected near vision. Further research is indicated by the authors.
