Contact lenses have assisted the refractive correction of keratoconus since the 19th century. In these case reports, the authors describe their experience with a new soft contact lens design.
The Soft K is a new soft lens comprising a thick fenestrated design to fit in patients with mild to moderate corneal distortion and fitting problems or physical intolerance to rigid gas-permeable (RGP) contact lenses. Three eyes with mild keratoconus from two 25-year-old patients (one man and one woman) were fitted with the Soft K contact lens. Both patients had previously worn other contact lens types.
Improvements in comfort and quality of vision compared with previously worn RGP or soft toric contact lenses were the most remarkable advantages objectively observed and subjectively described by both patients. For one patient, a professional soccer player, the benefits were also important in terms of compatibility with the dynamic environment of his activity, satisfying the need for stable correction and constant full field-of-view demand without spectacles. No physiologic complications such as edema or neovascularization were observed during the follow-up period.
This new soft lens design for irregular corneas is especially indicated for those with intolerance to RGP or other contact lenses and for patients for whom RGP lenses do not satisfy the dynamic environment inherent to some professional or leisure activities, particularly sport activity. This is a good option to consider in patients with mild to moderate keratoconus and good correction of slight or moderate irregular corneal astigmatism with good tolerance. Aftercare implications are also discussed.
自19世纪以来，隐形眼镜一直用于圆锥角膜的屈光矫正。在这些病例报告中，作者描述了他们使用一种新型软性隐形眼镜设计的经验。
Soft K是一种新型软性隐形眼镜，采用厚孔设计，适用于轻度至中度角膜变形、配镜困难或对硬性透气性（RGP）隐形眼镜存在身体不耐受的患者。为两名25岁患者（一男一女）的三只轻度圆锥角膜眼睛佩戴了Soft K隐形眼镜。两名患者此前都佩戴过其他类型的隐形眼镜。
与之前佩戴的RGP或软性散光隐形眼镜相比，舒适度和视力质量的改善是客观观察到且患者主观描述的最显著优点。对于一名职业足球运动员患者来说，这些益处对于其活动的动态环境的适应性也很重要，满足了在不戴眼镜的情况下稳定矫正和持续全视野需求。随访期间未观察到水肿或新生血管形成等生理并发症。
这种用于不规则角膜的新型软性隐形眼镜设计特别适用于那些对RGP或其他隐形眼镜不耐受的患者，以及RGP镜片无法满足某些职业或休闲活动（尤其是体育活动）固有动态环境的患者。对于轻度至中度圆锥角膜患者以及能够良好耐受、对轻度或中度不规则角膜散光进行良好矫正的患者来说，这是一个值得考虑的好选择。还讨论了后续护理的影响。
