Introduction
For patients with conjunctivitis, eye washing can generally be done using normal saline, artificial tears, 3% boric acid solution, sterile medical distilled water, or traditional Chinese medicine eye wash solutions (as directed by a physician). Normal saline has a composition close to that of human body fluids, is mild and non-irritating, and effectively rinses away eye secretions, dust, and other foreign particles, thereby relieving ocular discomfort. It is suitable for all types of conjunctivitis patients, who may wash their eyes 2–3 times daily.
For patients with conjunctivitis, eye washing can generally be done using normal saline, artificial tears, 3% boric acid solution, sterile medical distilled water, or traditional Chinese medicine (TCM) eye wash solutions (used as directed by a physician). Specific details are as follows:
1. Normal Saline: The composition of normal saline closely resembles that of human body fluids. It is mild and non-irritating, effectively rinsing away eye secretions, dust, and other foreign substances to reduce discomfort. Suitable for all types of conjunctivitis patients, eyes can be washed 2–3 times daily using sterile medical-grade saline.
2. Artificial Tears: Artificial tears moisturize the ocular surface and dilute inflammatory secretions, helping relieve symptoms such as dryness and itching. Preservative-free formulations can be used frequently and are ideal for patients with conjunctivitis accompanied by dry eyes. Usage should follow product instructions.
3. 3% Boric Acid Solution: This solution has mild antibacterial and cleansing properties, making it suitable for bacterial conjunctivitis patients with excessive discharge. The concentration must be accurate to avoid irritation from overly concentrated solutions. After washing, gently wipe around the eyes with sterile gauze.
p>4. Sterile Medical Distilled Water: Sterile distilled water is pure and free of impurities, allowing gentle irrigation of the eyes and reducing irritation from foreign particles. It is suitable for patients sensitive to other eye wash solutions. Ensure the packaging is intact and uncontaminated before use.5. Traditional Chinese Medicine Eye Wash (as directed by a physician): Some TCM eye washes have effects of clearing heat, detoxifying, and relieving itching. These should only be selected and used under medical supervision. Do not self-prepare or purchase products with unknown ingredients, as inappropriate components may worsen the condition.
Use sterile instruments when washing the eyes to prevent cross-infection; handle gently and avoid rubbing forcefully. If symptoms do not improve after eye washing, or if pain or blurred vision occurs, seek medical attention promptly.
