[Visual outcome with the array multifocal intraocular lens].
OBJECTIVE
To evaluate the visual outcome of Array IOL, and examine the location of the lens.


METHODS
255 eyes in 196 patients received phaco and IOL implantation were randomized as test group 121 eyes (Array IOL) and case control group 134 eyes (monofocal Hydroview IOL). Postoperative examination included distance and near, uncorrected and corrected visual acuity, refractive results, and measurement of corneal curvature. Follow-up period ranged from three months to one year.


RESULTS
Three months after surgery, 97.2% eyes (107/110) in test group with Array IOL had a distance visual acuity >/= 0.5, and in 24.5% (27/110) >/= 1.0. The difference was not significant (P > 0.05). 84.6% eyes (93/110) in test group had an uncorrected near acuity >/= 0.5 and 20.0% (22/110) >/= 1.0. The difference was significant (P < 0.01). The rate of wearing spectacles was 33.3% in test group and 90% in case control group. One month after surgery, 6 eyes in test group with haptic asymmetric location were not affected with visual recovery. The surgery-induced astigmatism in test group was 0.31 D, and no visual impairment appeared in both groups. Posterior capsule opacification was seen in 6 eyes in test group and 12 in case control group.


CONCLUSIONS
The implantation of Array IOL not only has a good distance uncorrected visual acuity, but also with better near visual acuity. Also this surgery is safe, reliable and no special complication-induced.
