Ophtalmology

For Lens Processing:

Adhesion: Must securely bond with the blocking wax or alloy used for holding the lens.

Protection: Prevents scratches and damage to the lens surface during grinding and polishing.

Peelability: Must peel off cleanly and easily from the lens after processing, without leaving residue or transferring alloy.

Color: Often blue to make it easy to distinguish and remove from the lens.

CT) use a puff of air to flatten the cornea, eliminating the need for anesthesia or contact.

Corneal Thickness Influence: The rigidity and thickness of the cornea affect the measurement; thinner corneas may result in artificially low readings, while thicker corneas may lead to falsely high ones.

Slit-Lamp Integration: The most common Goldmann applanation tonometer is mounted on a slit lamp.

Calibration: Instruments require daily calibration using standard weights to ensure accuracy.

Mire Rings (Goldmann): A split-image prism creates mires (marked rings) that are aligned to determine the applanation point and thus the IOP.
