How to use ophthalmic medical devices correctly?

How to use ophthalmic medical devices correctly requires following the key steps and precautions as below:

I. Preparation before Use

Strictly Follow the Instruction Manual

Read the device instruction manual in detail before operation to master the operation process, parameter settings and contraindications, and avoid risks caused by improper operation. Confirm that the device is in good performance and check whether the power supply, connection wires and accessories are in good condition.

Patient Assessment and Communication

Understand the patient's medical history (such as eye diseases, allergic history), visual needs and cooperation ability, and conduct optometry or pre-operative examinations when necessary. Explain the operation steps to the patient to relieve the tension and ensure that the patient maintains the correct posture.

Device Disinfection and Cleaning

All devices that come into contact with the eyes need to be thoroughly disinfected (such as by high temperature, ultraviolet rays or chemical disinfection) to avoid cross-infection. Wipe the surface of the device with a special cleaning agent, and avoid using irritating chemicals such as alcohol.

II. Operation Specifications

Principle of Aseptic Operation

Wear sterile gloves and use disposable consumables (such as eye cups, probe covers) to prevent contamination. Avoid touching the non-sterile areas during the operation and clean the device in a timely manner after the operation.

Precise Operation and Parameter Setting

Adjust the device parameters (such as the width of the slit lamp light band, the pressure of the tonometer) according to the patient's condition to ensure the accuracy of the data. Use auxiliary tools (such as topical anesthetics) to improve the patient's comfort and reduce the operation resistance.

Real-time Monitoring and Feedback

Closely observe the patient's reactions (such as pain, tearing) during the operation, and adjust the operation method in a timely manner or suspend the examination. For complex cases (such as corneal diseases), it is necessary to be operated by experienced medical staff.

III. Maintenance after Use

Device Cleaning and Maintenance

Wash the device with a neutral detergent after the operation, and avoid scratching the optical lenses with hard objects. Calibrate the equipment (such as the visual acuity chart, tonometer) regularly to ensure the measurement accuracy.

Storage and Record

Store the device in a dry and dark environment, and avoid high temperature or humidity. Record the usage situation, patient data and maintenance time in detail for easy traceability.

IV. Risk Prevention

Avoid Operation Errors

It is prohibited for untrained personnel to operate the equipment, and novices need to practice under guidance. Avoid collisions or drops of the device, and fix the probe and handle it gently when carrying it.

Infection Control

Strictly implement the disinfection process and use disposable protective supplies (such as eye masks, gloves). If there are abnormalities in the device (such as blurring, abnormal noise), stop using it immediately and report for repair.

Patient Safety Monitoring

Inform the patient of the possible discomforts (such as temporary blurred vision) after the operation and suggest the review time. For high-risk operations (such as laser treatment), it is necessary to inform the risk of complications in advance and sign the informed consent form.

V. Precautions for Special Devices

Contact Lenses: Qualifications for fitting are required. Select appropriate parameters according to the base curve and degree, and avoid wearing them for a long time to prevent keratitis.

Orthokeratology Lenses: Strictly follow the cleaning and wearing procedures and review the corneal status regularly.

Laser Equipment: Wear special protective goggles during the operation, ensure good ventilation in the treatment room and keep away from flammable substances.
