OCUVIQ™ dk-4 Flagship Series

Superior Safety. Precise Reshaping. Visual Freedom.

巅峰安全 · 开启高透氧角膜塑形新标准

The OCUVIQ™ dk-4 is a flagship-tier overnight Orthokeratology (Ortho-K) lens. Compared to the dk-3 series, it utilizes a patented material with an even higher oxygen permeability (Dk) value, elevating corneal safety during sleep to a superior dimension.

OCUVIQ™ dk-4 是一款顶级夜戴型角膜塑形镜。相较于 dk-3 系列，dk-4 采用了透氧率（Dk值）更高的专利材质，在确保塑形效果精准的同时，将夜间角膜安全性提升至更高维度。

Technology & Benefits 核心科技

dk-4 Flagship Oxygen Permeability

Represents the highest oxygen permeability in the series, providing oxygen supply close to that of the naked eye to safeguard corneal health.

旗舰级透氧率：代表系列最高性能。在夜间提供接近裸眼的氧气供应，保障角膜代谢健康，减少红血丝。

High-Precision Reverse Geometry

Refined design that guides corneal fluid dynamics gently and accurately for rapid reshaping and stable centration.

高精度逆几何结构：精细设计温和引导流体动力，实现快速塑形，确保翻身时镜片依然精准对位。

Enhanced Myopia Control

Utilizes peripheral defocus to effectively inhibit axial elongation, offering robust control for progressing myopia.

高效近视防控：利用周边离焦原理有效抑制眼轴增长，为加深较快的青少年提供更稳健的表现。

Moisture Enhancement Surface

Advanced hydrophilic treatment forms a protective tear film, improving comfort and ensuring smooth morning removal.

湿润度增强处理：高级亲水化处理形成保护水膜，改善异物感，防止镜片粘连，令摘镜更顺滑。

Q&A 常见问题

1. What is the difference between dk-4 and dk-3? / 护理和摘戴有特殊要求吗？

The core difference lies in the material. dk-4 offers higher oxygen permeability, giving the cornea more "room to breathe."

由于材质透氧性极高，更需注意防范油脂和蛋白沉淀。必须使用专业护理液日常揉搓，并定期进行除蛋白护理。

2. Does long-term use thin the cornea? / 会让角膜变薄吗？

No. It merely uses physical pressure to temporarily redistribute the epithelial layer. It is entirely reversible.

不会。这仅是通过物理压力暂时改变上皮层分布，不涉及组织切除或磨损。停戴后角膜会恢复原状。

3. How effective is it for astigmatism? / 对散光的矫正效果如何？

The dk-4 provides excellent astigmatism management through its precise alignment curve design.

具有优秀的散光处理能力，通过精准定位弧设计，有效矫正规则性散光，确保全天视觉清晰锐利。

4. Why is dk-4 suitable for teenagers? / 为什么适合青少年？

It provides a high safety margin for developing eyes and is a recognized method to slow myopia progression.

超高透氧性为生长发育期提供极高安全保障，且离焦设计是目前公认延缓近视发展的有效手段。
