Erythromycin ointment is primarily an antibiotic used to treat bacterial infections, particularly in the eyes. While it can be beneficial for certain conditions, it is not specifically indicated for treating dry eye syndrome, especially after cataract surgery. Dry eye syndrome is a multifactorial condition characterized by a loss of homeostasis of the tear film, which can lead to ocular symptoms and potential damage to the ocular surface.
After cataract surgery, many patients experience dry eyes due to several factors, including changes in tear production, the surgical procedure itself, and the healing process. The use of erythromycin ointment may not directly alleviate the symptoms of dry eyes, as it does not address the underlying issues related to tear production or evaporation.

For managing dry eye syndrome, especially post-surgery, the following approaches are generally recommended:
1. Artificial Tears: Over-the-counter artificial tear solutions are often the first line of treatment for dry eyes. These products help lubricate the eye and provide temporary relief from dryness. It's essential to choose preservative-free options if you need to use them frequently.

2. Prescription Medications: If over-the-counter solutions are insufficient, a healthcare provider may prescribe medications like cyclosporine A (Restasis) or lifitegrast (Xiidra), which help increase tear production and reduce inflammation.

3. Punctal Plugs: These are small devices inserted into the tear ducts to block drainage, thereby increasing the amount of moisture on the surface of the eye. This can be particularly helpful for patients with moderate to severe dry eyes.

4. Warm Compresses and Eyelid Hygiene: Applying warm compresses can help unclog blocked meibomian glands, which are responsible for producing the oily layer of the tear film. Maintaining good eyelid hygiene can also help reduce inflammation and improve tear quality.

5. Dietary Changes: Increasing omega-3 fatty acids in the diet, either through food sources like fish or supplements, may help improve tear production and reduce symptoms of dry eye.

6. Environmental Modifications: Reducing exposure to wind, smoke, and dry air can help alleviate symptoms. Using a humidifier at home and taking breaks from screens can also be beneficial.

7. Surgery: In severe cases, surgical options may be considered, such as thermal pulsation treatment or other procedures aimed at improving tear production and retention.

Given that your grandmother has been suffering from dry eye symptoms for an extended period, it would be advisable for her to consult with an ophthalmologist or a specialist in dry eye management. They can provide a comprehensive evaluation and tailor a treatment plan based on her specific needs and the severity of her condition.
In summary, while erythromycin ointment may not be effective for treating dry eyes after cataract surgery, there are numerous other strategies and treatments available that can help manage her symptoms effectively. It is crucial to seek professional guidance to determine the best course of action.
