To analyze the correlation between automated refraction and manifest refraction after implantation of a trifocal intraocular lens or its toric version.
This cross-sectional study involved 105 eyes of 105 patients. Subjects were divided in two groups: 62 with trifocal (AcrySof PanOptix) and 43 with trifocal toric (AcrySof PanOptix Toric) intraocular lenses. Automated refraction was employed as starting point for obtaining the manifest refraction. Automated refraction and manifest refraction measurements were analyzed and compared using the vector analysis 3 months after the surgery.
In both groups, the higher differences between automated refraction and manifest refraction measurements were found for the cylinder and the spherical equivalent (M). Cylinder values for PanOptix were: -0.60 ± 0.36 D with automated refraction and -0.17 ± 38 D with manifest refraction ( < 0.001); for PanOptix Toric, the values were: -0.49 ± 0.31 D with automated refraction and -0.05 ± 0.21 D with manifest refraction ( < 0.001). M values for PanOptix were: -0.23 ± 0.31 D with automated refraction and -0.03 ± 0.16 D with manifest refraction ( < 0.001); for PanOptix Toric, the values were: -0.13 ± 0.40 D with automated refraction and 0.01 ± 0.12 D with manifest refraction ( < 0.001). For the PanOptix group, intraclass correlation coefficients were: 0.51 (sphere), 0.64 (cylinder), 0.42 (M), 0.62 (J0), and 0.37 (J45). For the PanOptix Toric group, the intraclass correlation coefficients were: 0.39 (sphere), 0.61 (cylinder), 0.39 (M), 0.53 (J0), and 0.09 (J45).
The results of this study suggest that patients implanted with the trifocal and the trifocal toric intraocular lens under study showed similar automated refraction results between them, with a slight trend to more negative amounts of cylinder and M. Nevertheless, clinicians should carefully confirm all parameters of the refraction with manifest refraction.
分析三焦点人工晶状体或其散光型植入术后自动折射与显微微折射之间的相关性。
本横断面研究纳入了 105 例 105 只眼的患者。患者分为两组：62 例三焦点（AcriSof PanOptix）组和 43 例三焦点散光型（AcriSof PanOptix Toric）组。自动折射作为获得显微微折射的起点。术后 3 个月，采用向量分析法分析并比较自动折射和显微微折射测量值。
两组中，自动折射和显微微折射测量值之间的差异最大的是散光和等效球镜（M）。PanOptix 的散光值分别为：自动折射为-0.60±0.36D，显微微折射为-0.17±38D（ < 0.001）；PanOptix Toric 的散光值分别为：自动折射为-0.49±0.31D，显微微折射为-0.05±0.21D（ < 0.001）。PanOptix 的 M 值分别为：自动折射为-0.23±0.31D，显微微折射为-0.03±0.16D（ < 0.001）；PanOptix Toric 的 M 值分别为：自动折射为-0.13±0.40D，显微微折射为 0.01±0.12D（ < 0.001）。PanOptix 组的组内相关系数分别为：0.51（球镜）、0.64（散光）、0.42（M）、0.62（J0）和 0.37（J45）。PanOptix Toric 组的组内相关系数分别为：0.39（球镜）、0.61（散光）、0.39（M）、0.53（J0）和 0.09（J45）。
本研究结果表明，研究中植入三焦点和三焦点散光型人工晶状体的患者之间自动折射结果相似，散光和 M 呈轻微负偏趋势。然而，临床医生应仔细用显微微折射确认折射的所有参数。
