Product Overview
Retina lenses (for slit lamp) are precision ophthalmic instruments designed to observe the patient's fundus and examine the internal structures of the eye through the pupil in coordination with a slit lamp microscope. They enable doctors to make accurate diagnoses of eye diseases and other related symptoms with enhanced clarity and reliability.
This product complies with the relevant provisions of ISO 13485, ensuring consistent quality and safety for clinical use.

How to Use
Users should be familiar with the operation of retina lenses and the slit lamp microscope before use.
When examining a patient's eyes, align the lens with the patient's pupil and ensure that the shield ring of the lens faces the doctor while the other side faces the patient's eyes.
Maintain a sufficient distance between the lens and the patient's eyes so that the size of the retinal imaging matches the diameter of the lens.
Please minimize the brightness of the light as much as possible. Doing so reduces reflectiveness and improves imaging contrast.
Cleaning and Maintenance
Cleaning: Wipe the lenses with soft cotton dipped in absolute alcohol.
Warning: Do not expose the lenses to high pressure or boil them for sterilization.
Important Notes
Please do not store or use this equipment in environments that are flammable, explosive, high-temperature, high-humidity, or dusty. Use it in a clean room and keep the product clean and dry.
Do not wipe the surface of the lens with hands or hard objects.
