Abstract Details

Purpose:

To evaluate and compare the 5-year postoperative anterior (ACO) and posterior capsular opacification (PCO) and the level of anterior capsule retraction after implantation of two different designs of single-piece hydrophobic acrylic IOLs.

Setting:

Hospital St. John, Vienna, Austria Krankenhaus der Barmherzige Brüder Wien,

Methods:

In this randomized, controlled, prospective, double blind study, 34 patients (age range, 61 to 80 years) with bilateral senile cataract were enrolled. Each patient underwent surgery with implantation of an AcrySof SA60AT (group A, interrupted optic edge) in one eye and Tecnis ZCB00 (group B, continuous optic edge) in the fellow eye by four experienced surgeons. At one, three and five years postoperatively, the PCO level was evaluated with the EPCO software whereas the level of ACO and capsule retraction was evaluated and graded subjectively.

Results:

No significant differences in PCO score were found between groups A and B during all follow-up visits (3 years: 0.23±0.36vs.0.22±0.32, p=0.66 and 5 years: 0.06±0.12vs.0.07±0.13, p=0.35). A significant increase in the PCO score was found between 3 and 5 years postoperatively (p<0.01). ACO was present in groups A and B in 18.0% and 2.7% (p=0.03), and in 92.0% and 24.0% of eyes (p<0.01) at 3 and 5 years after surgery, respectively. Capsular phimosis (5 years 32.0%) and glistenings (5 years 89.0%,) were only observed in group A.

Conclusions:

Both IOLs had a similar low PCO rate five years after surgery, but more anterior capsule opacification and retraction was observed with the interrupted optic edge IOL.
