What shape is the needle point used in procedures involving the cornea or sclera that requires precise penetration?

The spatula point needle is specifically designed for precise penetration, making it particularly suitable for procedures involving delicate structures such as the cornea and sclera. This needle has a broader, flat tip that allows for a more controlled entry into tissues. The spatula shape minimizes the risk of tearing or damaging surrounding tissues during procedures where accuracy is critical.

In contrast, the other needle points, such as flat, curved, and triangular, may not provide the same level of precision for these delicate procedures. The flat point typically lacks the controlled penetration needed for intricate work in the eye. Curved points are generally used for different types of applications, such as suturing where flexibility in the approach is necessary, whereas triangular points may be designed for cutting but are less effective for controlled entry in delicate tissues like the cornea and sclera.
