To assess the long-term increase in surface light scattering of foldable hydrophobic acrylic intraocular lenses (IOLs) and to evaluate its effect on visual acuity.

Cross-sectional study.
The clinical records of patients who received an Acrysof IOL (study group) or a Sensar AR40 or AR40e IOL (control group) were reviewed retrospectively. Surface light scattering of IOLs was measured 1 year postoperatively or later. The corrected distance visual acuity (CDVA) at the surface-light-scattering examination was compared with the CDVA 1 month after IOL implantation. The changes in CDVA over time were compared with the increase in surface light scattering.
The study evaluated 466 eyes of 337 patients. Surface light scattering in the study group continued to increase up to 15 years postoperatively. The light scattering was higher on the anterior IOL surface after 4.5 years. Increased surface light scattering had no significant impact on CDVA; however, there were more cases with decreased CDVA when the surface light scattering exceeded 50 computer-compatible tape steps.
Surface light scattering with the implanted foldable hydrophobic acrylic IOL continuously increased during the postoperative years and was a risk for decreased visual acuity.

横断面研究。
回顾性分析接受 Acrysof IOL（研究组）或 Sensar AR40 或 AR40e IOL（对照组）的患者的临床记录。术后 1 年或更长时间测量 IOL 的表面光散射。将表面光散射检查时的矫正远视力（CDVA）与 IOL 植入后 1 个月的 CDVA 进行比较。比较随时间变化的 CDVA 与表面光散射的增加。
本研究评估了 337 名患者的 466 只眼。研究组的表面光散射在术后 15 年内持续增加。4.5 年后，前 IOL 表面的散射光更高。增加的表面光散射对 CDVA 没有显著影响；然而，当表面光散射超过 50 个计算机兼容带步时，CDVA 下降的病例更多。
植入的折叠式疏水性丙烯酸人工晶状体的表面光散射在术后数年持续增加，是视力下降的一个风险因素。
