Our aim was to evaluate the resolution of negative dysphotopsia after supplementary implantation of a sulcus-fixated intraocular lens (IOL).
This was a retrospective case series. Patients with severe negative dysphotopsia were treated with supplementary implantation of the Rayner Sulcoflex Aspheric (653 L) IOL. Primary outcome measurements were subjectively reported complaints of dysphotopsia, best corrected distance visual acuity (CDVA), iris-IOL distance, anterior chamber depth (ACD) and volume (ACV), angle opening distance and trabecular-iris space area at 500 and 750 μm.
A Rayner Sulcoflex IOL was implanted in seven patients (nine eyes) with negative dysphotopsias. Symptoms resolved completely in six eyes, partially in one eye and remained unchanged in two eyes. We did not find any significant changes in CDVA. Angle opening distance, ACD, ACV and iris-IOL distance reduced significantly after Sulcoflex IOL implantation.
Supplementary implantation of a Sulcoflex IOL can successfully treat negative dysphotopsia. The decrease in anterior segment dimensions in combination with the displacement of light rays by the rounded edges of a Sulcoflex IOL may contribute to the resolution of symptoms.
我们的目的是评估在补充植入沟固定人工晶状体（IOL）后，负性 dysphotopsia 的消退情况。
这是一项回顾性病例系列研究。患有严重负性 dysphotopsia 的患者接受了 Rayner Sulcoflex 非球面（653 L）IOL 的补充植入。主要结局指标是主观报告的 dysphotopsia 主诉、最佳矫正远视力（CDVA）、虹膜 - IOL 距离、前房深度（ACD）和容积（ACV）、500 和 750 μm 处的房角开放距离以及小梁 - 虹膜间隙面积。
七名患有负性 dysphotopsia 的患者（九只眼）植入了 Rayner Sulcoflex IOL。六只眼症状完全消退，一只眼部分消退，两只眼症状无变化。我们未发现 CDVA 有任何显著变化。植入 Sulcoflex IOL 后，房角开放距离、ACD、ACV 和虹膜 - IOL 距离显著减小。
补充植入 Sulcoflex IOL 可成功治疗负性 dysphotopsia。前段尺寸的减小以及 Sulcoflex IOL 圆形边缘对光线的位移可能有助于症状的消退。
