Abstract Details


Posterior capsular opacification (PCO) after cataract surgery is still one of the important complications. In this study, we concentrate the shapes of haptics on 1-piece hydrophobic acrylic intraocular lens (IOL) to prevent PCO.


Department of Ophthalmology, Dokkyo Medical University, Tochigi, Japan


Subjects comprised 50 eyes that underwent phacoemulsification with complete continuous capsular capsulorhexis. SA60AT (Alcon) or ZCB00 (AMO) are randomly selected for the implantations. The SA60AT has lost square edge on optics-haptics junction; the ZCB00 has been devised square edge on optics-haptics junction. Images were taken using an EAS-1000 (NIDEK) after 1, 3 and 6 months postoperatively. To analyze the PCO, retroillumination images was quantitatively analyzed using imaging analysis software, Scion Image (Scion) and ratios of PCO were evaluated between the two IOLs.


The development of PCO in the SA60AT group was higher than in the ZCB00 group during the all investigated periods. The opacification inside of optics-haptics junction is significant higher than in the SA60AT group in detail. However, the opacification was prevented in the ZCB00 group.


The development of PCO was higher the SA60AT than the ZCB00. The devised square edge on optics-haptics junction is effective to prevent PCO.
