Why might contact biometry pose a risk during ocular measurement?

• A. It requires special imaging techniques
• B. It can lead to corneal infections due to direct contact
• C. It generates heat affecting measurement accuracy
• D. It needs patient sedation

Answer: (B)

Contact biometry involves placing a measurement device directly onto the surface of the eye, which can increase the risk of corneal infections. This is primarily because any device that touches the eye has the potential to transfer bacteria or other pathogens, especially if proper sterile techniques are not followed. The direct contact can lead to abrasions or breaks in the corneal epithelium, providing an entry point for microbes. Understanding this risk is critical in diagnostic procedures, as corneal infections can lead to significant complications, including pain, vision loss, and the need for aggressive treatment. Therefore, maintaining strict hygiene protocols during contact biometry is essential to minimize these risks and ensure patient safety during ocular measurements.
