To evaluate the long-term change in surface light scattering of several hydrophobic acrylic intraocular lenses (IOLs) and the clinical importance of these findings.
A total 160 eyes of 96 patients who underwent cataract surgery with implantation of a hydrophobic acrylic IOL were enrolled in this study. Patients were divided into two groups according to the IOL manufacturer: Acrysof IOL (MA60BM, SA60AT, SN60WF; Alcon, Inc.) and Sensar or Tecnis IOLs (AR40e, ZA9003, ZCB00; Abbot Medical Optics, Inc.). The surface light scattering was measured by area densitometry using a Scheimpflug camera (EAS-1000, NIDEK, Aichi, Japan).
The anterior and posterior surface light scattering in the Acrysof IOLs steadily increased up to 10 years postoperatively (r = 0.870, p < 0.001 and r = 0.855, p < 0.001, respectively). The intensity of anterior and posterior surface light scattering in the Acrysof IOLs was significantly greater than that in the Sensor or Tecnis IOLs (p < 0.05), except the posterior surface light scattering during 1 to 2 years postoperatively.
Surface light scattering of Acrysof hydrophobic acrylic IOLs gradually increases postoperatively as time progresses. As the surface light scattering of IOLs increases, Neodymium:YAG (Nd:YAG) laser posterior capsulotomy typically becomes more difficult to perform. In cases of posterior capsule opacification (PCO) in Acrysof IOLs, laser posterior capsulotomy should be considered earlier than in the typical case.
