In a five-year study, permanent wear of soft contact lenses was achieved by selecting patients and lenses properly, and offered a viable and probably safer alternative to intraocular lenses. Twenty-five of these 49 patients wore their initial lens or a similar lens continuously for over three years. A visual acuity of 6/12 (20/40) or better was obtained in 45 (91.8%) patients. Four (8%) had ocular problems not related to contact lenses that precluded the same improvement in central vision. The most common complications were reversible epithelial edema, superficial vascularization, and conjunctivitis. There was a strong correlation between edema and superficial vascularization in eyes fitted with lenses having a poorly made inside bevel. Calcium deposits were the most frequently found spot on permanent-wear soft contact lenses (nine eyes, 18%).
在一项为期五年的研究中，通过合理选择患者和镜片，实现了软性隐形眼镜的长期佩戴，并且为人工晶状体提供了一种可行且可能更安全的替代方案。这49名患者中有25名连续三年以上佩戴其最初的镜片或类似镜片。45名（91.8%）患者的视力达到了6/12（20/40）或更好。4名（8%）患者有与隐形眼镜无关的眼部问题，这妨碍了中心视力的同样改善。最常见的并发症是可逆性上皮水肿、浅层血管化和结膜炎。在佩戴内斜面制作不佳的镜片的眼睛中，水肿和浅层血管化之间存在很强的相关性。钙沉积物是长期佩戴软性隐形眼镜上最常发现的部位（9只眼，18%）。
