Until the advent of bifocal hydrogel lenses, monovision or reading glasses were the modes of correction for hydrogel contact lens wearing presbyopes. Recent design innovations and improvements in the manufacturing technology of soft contact lenses have made possible new developments in bifocal hydrogel lenses. Patient selection and patient education play key roles in optimizing patient success. There are several hydrogel bifocal designs that are possible for the presbyope. The variations of these designs and their pertinent considerations are discussed.
在双焦点水凝胶镜片出现之前，单眼视力矫正或佩戴阅读眼镜是水凝胶隐形眼镜佩戴老花眼患者的矫正方式。近期软质隐形眼镜制造技术的设计创新与改进使得双焦点水凝胶镜片有了新进展。患者选择和患者教育在优化患者治疗效果方面起着关键作用。对于老花眼患者，有几种水凝胶双焦点设计可供选择。本文将讨论这些设计的差异及其相关注意事项。
