Posterior Capsule Opacification Clinical Trial
Official title:
Posterior Capsule Opacification and Optical Quality of Different Hydrophobic Acrylic Intraocular Lenses
The most frequent long-term complication of cataract surgery remains to be posterior capsule
opacification (PCO). During the past decades many new intraocular lenses (IOL) with optimized
lens material and design were introduced. We propose a study comparing three acrylic
single-piece IOLs with different design and hydrophobic material. All IOLs (Hoya NY-60, HOYA
Surgical Optics GmbH; EyeCee One, Nidek Co., Aichi, Japan) are commercially available and are
used for routine cataract surgery. In this study a comparison of PCO score of all two IOLs, a
comparison of optic quality with wavefront analyses, visual acuity, contrast sensitivity, IOL
decentration and tilt, slitlamp examination, fibrosis, glistening intensity (subjectively
scored), YAG capsulotomy rate, and safety parameters (IOL related adverse reactions) of the
investigated IOLs will be performed. Since PCO develops slowly within years, a long-term
follow-up of three years will be necessary.
As those IOLs are currently often implanted IOLs, their performance on PCO development and
their optical quality is of high interest for the ophthalmologic community.
