To compare the clinical classification of anterior capsule opacification (ACO) after femtosecond laser-assisted cataract surgery with the mean density values of ACO provided by rotating Scheimpflug device (Pentacam HR) densitometry software and to determine which densitometry method correlates best with the clinical classification.

Prospective comparative study.
Femtosecond laser-assisted cataract surgery was performed using the Victus platform between June 2014 and March 2015. Inclusion criteria were age between 55 years and 85 years, a pupil diameter larger than 6.0 mm in full mydriasis, no intraoperative complications, a curvilinear anterior capsulotomy without tears, and an intraocular lens in the correct intracapsular position at the end surgery. The ACO was measured by a clinical classification ranging from 0 to 4. In addition, ACO density was measured with the Scheimpflug device using 3 densitometry methods (area, linear, and peak).
The study comprised 32 eyes of 32 patients. Area and linear densitometry values provided by the Scheimpflug device had a strong correlation with the values obtained by clinical classification, whereas peak densitometry values had a very weak correlation at 6 months (area densitometry: Spearman ρ = 0.78; P < .0005; linear densitometry: ρ = 0.73; P < .0005; peak densitometry ρ = 0.21; P = .2).
The Scheimpflug device provided an objective measurement of ACO after cataract surgery.

前瞻性比较研究。
2014 年 6 月至 2015 年 3 月期间使用 Victus 平台进行飞秒激光辅助白内障手术。纳入标准为年龄 55 至 85 岁，充分散瞳后瞳孔直径大于 6.0mm，术中无并发症，无撕裂的曲线性前囊切开术，术后最终晶状体位置正确。ACO 通过临床分类范围从 0 到 4 进行测量。此外，使用 Scheimpflug 设备通过 3 种密度计方法（面积、线性和峰值）测量 ACO 密度。
该研究包括 32 名患者的 32 只眼。Scheimpflug 设备的面积和线性密度计值与临床分类获得的值具有很强的相关性，而峰值密度计值在 6 个月时相关性非常弱（面积密度计：Spearman ρ=0.78；P<.0005；线性密度计：ρ=0.73；P<.0005；峰值密度计ρ=0.21；P=0.2）。
Scheimpflug 设备提供了白内障手术后 ACO 的客观测量。
