John ALK Marker: Precision for Radial Keratotomy Procedures

The John ALK marker is a specialized ophthalmic instrument designed to facilitate accurate radial keratotomy procedures. Featuring four longer marks positioned at the 3, 6, 9, and 12 o'clock positions, this tool ensures consistent alignment during surgical incisions. The device includes eight radial blades arranged around a central hub, providing clear visual guides for surgeons. With a flat profile measuring 20.0 cm in length, it offers ergonomic handling and stability during delicate eye surgeries. This marker is essential for maintaining precision in anterior segment operations within hospital and clinic settings.

• Guiding radial incisions during radial keratotomy (RK) procedures
• Establishing precise clock-position references for corneal surgery
• Assisting in the alignment of optical zones during refractive interventions
• Providing stable visualization aids for anterior segment surgeons

Specifications
