To assess the acceptability of clinical outcome achieved with use of the SI-30NB lens, as well as the incidence of any lens related complications.

This prospective study evaluated 210 consecutive eyes undergoing endocapsular phacoemulsification cataract surgery (EPECS), with implantation of the AMO SI-30NB foldable three-piece lens, commencing with the first patient in our practice receiving this implant. There was 99% follow-up for at least three months, with a mean of nine months, and a range of three to 14 months. Incisions were a maximum of 3.2 mm in size, and this allowed minimisation of astigmatism, and maximisation of early visual rehabilitation.

The final visual acuity results were excellent, with 95% of cases achieving corrected vision of 6/12 or better. All cases without pre-existing ocular pathology achieved corrected vision of 6/6, apart from a single case which achieved 6/9, but the patient died before follow-up. The lens-related complication rate was less than 1% (two patients). No decentration of any other implant occurred, and no patient complained of edge glare. There were no cases of iris chafing or pigment dispersion. Only three patients (1.4%) required Yag posterior capsulotomy in the first 14 months of the study. Central bag-bag fixation was achieved in 206 of the 210 cases in the study (98%).

The results achieved using the SI-30NB lens with a small incision phaco procedure were excellent. Lens-related complications occurred in only two cases and very few cases have had problems with posterior capsular opacification.
