Abstract Details

Purpose:

To evaluate and compare the 3-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:

Academic Teaching Hospital of St. John Vienna Austria

Methods:

Randomized, controlled, prospective, double blind study including 100 eyes of 50 patients (age range, 61 to 80 years) with bilateral senile cataract. 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. Lens allocation to the first or second operated eye followed a randomization process. At one and three 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 (1 year: 0.06±0.12vs.0.07±0.13, p=0.35; 3 years: 0.23±0.36vs.0.22±0.32, p=0.66). A significant increase in the PCO score was found between 1 and 3 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 1 and 3 years after surgery, respectively. Capsular phimosis (1 year 18.0%, 3 years 30.0%) and glistenings (1 year 66.0%, 3 years 86.0%) were only observed in group A.

Conclusions:

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