PURPOSE
To determine whether higher-order aberrations can explain the monocular diplopia reported by a patient.
DESIGN
Observational case report.
METHODS
A patient complaining of monocular diplopia was examined with the Hartmann-Shack aberrometer to determine if the higher-order wavefront aberrations could account for the diplopia. The patient had a mild cortical cataract, and measurements were made before and after lensectomy. In addition, the retinal image was simulated using Zernike polynomials.
RESULTS
Spherical aberration (0.20 microm for 4-mm pupil) and secondary astigmatism (-0.12 microm) were increased in the eye. The simulated retinal image had a double configuration that was approximately the same as the subjective image reported by the patient. After cataract surgery, the diplopia disappeared, and the spherical aberrations and secondary astigmatism were considerably decreased.
CONCLUSIONS
The monocular diplopia probably stemmed from the combined effects of spherical aberration and secondary astigmatism caused by the cortical cataract.
目的
确定高阶像差是否能够解释一名患者所报告的单眼复视。
设计
观察性病例报告。
方法
使用哈特曼-夏克像差仪对一名主诉单眼复视的患者进行检查，以确定高阶波前像差是否可以解释复视。该患者患有轻度皮质性白内障，并在晶状体切除术前和术后进行了测量。此外，使用泽尼克多项式模拟视网膜图像。
结果
患眼的球差（4毫米瞳孔时为0.20微米）和继发性散光（-0.12微米）增加。模拟的视网膜图像具有双重结构，与患者报告的主观图像大致相同。白内障手术后，复视消失，球差和继发性散光显著降低。
结论
单眼复视可能源于皮质性白内障引起的球差和继发性散光的联合作用。
