To demonstrate the utility of piggyback multifocal intraocular lenses (IOLs) for a hyperopic-presbyopic surprise after cataract surgery in highly myopic patients.
Case report.
A 43-year-old woman with high myopia presented with dense subcapsular cataracts. The IOL power calculated with the Haigis formula gave a lens of -7D for emmetropia in the right eye. The refractive result was a spherical equivalent refractive error of +2.25. To overcome refractive surprise, a refractive multifocal +3D Sulcoflex 653F with an additional 3.5D for near vision was implanted, achieving a best-corrected visual acuity of 20/40. The lens offered her good intermediate vision for computer work.
With a Sulcoflex IOL, it is possible to achieve good near-intermediate visual acuity and spectacle independence, especially in highly myopic eyes with good near visual acuity. In addition, the implantation of these IOLs might correct residual refractive errors following previous implantation of a monofocal IOL.
展示后发性远视型白内障术后使用搭桥式多焦点人工晶状体（IOL）治疗高度近视患者远视超视力的效果。
病例报告。
一名 43 岁女性，高度近视，患有致密的后发性白内障。使用 Haigis 公式计算的 IOL 光焦度在右眼给予 -7D 以实现正视。屈光结果为等效球镜屈光误差+2.25D。为了克服屈光超视力，植入了一个具有 3.5D 近视力附加度数的屈光性多焦点+3D Sulcoflex 653F，实现了最佳矫正视力 20/40。该晶状体为她提供了良好的计算机工作中距离视力。
使用 Sulcoflex IOL 可以实现良好的中距离至近距离视力和不依赖眼镜，尤其适用于具有良好近视力的高度近视眼。此外，这些 IOL 的植入可能会纠正先前植入单焦点 IOL 后的残余屈光误差。
