PURPOSE
To validate a new methodology to evaluate the impact of astigmatism in pseudophakia using an astigmatic defocus curve.
SETTING
Hospital Oftalmológico de Brasilia, Brazil.
DESIGN
Non-randomized cohort study.
METHODS
For every point of the defocus curve, from -2.00 to +3.00 with 0.50D intervals, visual acuity was assessed with optically induced astigmatism (0.50D, 1.00D and 1.50D at 90 and 180 degrees) in pseudophakic patients implanted with a refractive-enhanced intraocular lens.
RESULTS
Twelve patients were analyzed. A statistically significant difference was found between the 90° (ATR) and 180°(WTR) axis with 1.50D astigmatism, providing better visual acuity in ATR astigmatism (p < 0.05).
CONCLUSION
This new methodology is reproducible, useful and may predict residual astigmatism tolerance in pseudophakic patients, which may help with surgery planning and IOL decision-making.
目的
使用散光离焦曲线验证一种评估散光对人工晶状体眼影响的新方法。
设置
巴西巴西利亚眼科医院。
设计
非随机队列研究。
方法
对于离焦曲线的每个点，从-2.00到+3.00，间隔为0.50D，对植入屈光增强型人工晶状体的人工晶状体眼患者，通过光学诱导散光（90度和180度处分别为0.50D、1.00D和1.50D）评估视力。
结果
分析了12例患者。在1.50D散光时，90°（顺规）和180°（逆规）轴之间存在统计学上的显著差异，顺规散光的视力更好（p < 0.05）。
结论
这种新方法具有可重复性、实用性，并且可以预测人工晶状体眼患者的残余散光耐受性，这可能有助于手术规划和人工晶状体的决策。
