圆锥角膜是一种不断进展的致盲性眼病，其特征是角膜变薄和突起，伴有不规则散光和视力下降。早期圆锥角膜的不规则散光可通过框架眼镜矫正，对于中重度圆锥角膜的不规则散光，框架眼镜不再适用，接触镜成为患者矫正视力的最佳选择。接触镜种类繁多，在接触镜的选择上难以抉择，如长时间试戴镜片会增加患者的不适，影响整体感受，也大大增加了医生的工作量。因此，本文对接触镜的分类、接触镜在不同圆锥角膜类型中的应用、接触镜配戴中的并发症及其未来展望等方面予以汇总和讨论，以期了解接触镜在圆锥角膜中的临床应用与管理，有助于进一步发挥接触镜在圆锥角膜中的应用价值。

Keratoconus is a progressive blinding eye disease that characterized by corneal thinning and protrusion, which accompanied with irregular astigmatism and impaired visual acuity.The irregular astigmatism of early keratoconus can be corrected by spectacles. For the irregular astigmatism of moderate to severe keratoconus, spectacles are no longer suitable, and contact lenses are the best choice for patients to restore vision. There are various types of contact lenses, making the selection very difficult. In addition, trying on lenses for a long time will increase the discomfort and overall feeling of patients, and greatly increase the workload of doctors. Thus, the article aims to summarize and discuss the classification of contact lenses, the application of contact lenses in different types of keratoconus, the complications of contact lens, and the current status and prospect of contact lenses, with a view to understanding the management and clinical application of contact lenses in keratoconus patients and to further improving the application value of contact lenses in keratoconus.
