PURPOSE
To determine whether higher-order aberrations explain patient-reported monocular triplopia.
DESIGN
Observational case report.
METHOD
A patient complaining of monocular triplopia was examined with a Hartmann-Shack aberrometer to determine whether higher-order wavefront aberrations could account for the triplopia. The patient had a mild nuclear cataract; measurements were made before and after lensectomy. The retinal image was simulated using the Zernike polynomials.
RESULT
Spherical aberration (-0.18 microm, 4 mm pupil) and trefoil aberration (-0.16 microm) were increased. The simulated retinal image had a triple configuration similar to the subjective image reported by the patient. After cataract surgery, the subjective triplopia disappeared; spherical, and trefoil aberrations were markedly decreased.
CONCLUSION
The monocular triplopia probably stemmed from combined effects of spherical and trefoil aberrations caused by the nuclear cataract.
目的
确定高阶像差是否能解释患者报告的单眼复视。
设计
观察性病例报告。
方法
对一名主诉单眼复视的患者使用哈特曼-夏克像差仪进行检查，以确定高阶波前像差是否可解释复视。该患者有轻度核性白内障；在晶状体切除术前和术后进行测量。使用泽尼克多项式模拟视网膜图像。
结果
球差（-0.18微米，4毫米瞳孔）和三叶草像差（-0.16微米）增加。模拟的视网膜图像具有与患者报告的主观图像相似的三重结构。白内障手术后，主观复视消失；球差和三叶草像差明显降低。
结论
单眼复视可能源于核性白内障引起的球差和三叶草像差的综合作用。
