Case Study: Eye Lesion Detection Medical Lens
Lesion Detection Lens Types
Medical detection lenses designed to identify eye diseases are divided into two types based on optical working distance: long-distance detection lenses and zero-distance detection lenses.
Long-Distance Detection Lens (Approximately 15mm from the Eye)
- Advantages: Non-contact design ensures safety. Detection of lesions is painless, minimizing discomfort, which makes it more acceptable to patients.
- Disadvantages: Requires patient cooperation for accurate detection.
Zero-Distance Detection Lens (In Direct Contact with the Eye)
- Advantages: Specifically designed for infants who may not cooperate during examinations. This is particularly important when detecting congenital eye diseases in newborns, enabling early diagnosis and treatment.
- Disadvantages: Direct contact with the eye may cause discomfort for the patient.
