Abstract

PURPOSE

To compare the visual outcomes of two intraocular lenses (IOLs) (Acri.Smart [multifocal] and AT-45 [accommodative]) for correction of distance and near visual acuity with a LASIK procedure for presbyopia (presbyLASIK) and a control group fitted with a standard distance-correcting monofocal IOL (Acrysof).

METHODS

Distance and near decimal visual acuities were measured under similar conditions before and 6 months postoperatively in 45 patients (87 eyes) who comprised four groups: Acri. Smart IOL, AT-45 IOL, presbyLASIK, and control (monofocal IOL). All acuity measures were standardized at 20 m (distance, projected chart) and 40 cm (near). All visual acuity measures were taken in the same ambient light conditions and contrast. All data were collected in a randomized, masked style.

RESULTS

Pre- and postoperative distance mean visual acuities for the Acri.Smart IOL, AT-45 IOL, presbyLASIK, and controls groups, respectively, were 0.15±0.21 and 0.66±0.35; 0.31±0.14 and 0.68±0.28; 0.35±0.15 and 0.80±0.33; and 0.32±0.18 and 0.59±0.29. Pre- and postoperative near mean visual acuities for the Acri.Smart IOL, AT-45 IOL, presbyLASIK, and control groups, respectively, were 0.13±0.21 and 0.62±0.35; 0.43±0.22 and 0.51±0.27; 0.15±0.20 and 0.68±0.33; and 0.40±0.29 and 0.30±0.13. Distance and near visual acuities improved significantly after surgery (P <.05) except near acuities for the AT-45 IOL and control groups.

CONCLUSIONS

For these patients, distance and near acuities improved with presbyLASIK and Acri. Smart IOLs when compared with controls. In those patients treated with the AT-45 IOL, average distance visual acuity improved but not near visual acuity.
