Purpose: We investigated the potency to inhibit posterior capsule
opacification (PCO) of an intraocular lens (IOL) with a modified backside
design.
Methods: 19 patients underwent cataract surgery and recieved an
experimental IOL in one eye and an control IOL in the other eye. The mean
age of the patients was 70,1 (54-79). Visual acuity (Regan-Chart) und
PCO rate (fibrosis and pearls) of both eyes were measured each year -
for three years. Mann-Whitney rank-sum-test was performed.
Results: There was no statistically significant difference 1 resp.
3 years postoperatively between the visual acuity with the experimental
and the control IOL (p=0,6443 and p=0,2638). Concerning the PCO rate a
statistically significant difference 1 year postoperatively (p=0,0031)
was seen, but not in the third year (p=0,0201). For the whole period of
the study we could not find a difference between the two groups concerning
the YAGrates (p=0,6135).
Conclusion: There was no advantage in the visual acuity for the
experimental lens, though we found a lower rate of PCO in this lens in
relation to the control IOL.
