there is no eye drop medication known as "Topviz." It's possible that this medication was developed or released after my last knowledge update, or it might be known by a different name or under a different brand in different regions.
If "Topviz" is a new eye drop medication, I don't have specific information about its side effects. To obtain accurate and up-to-date information about any medication, including potential side effects, it is best to consult the prescribing doctor or pharmacist. They can provide you with the most current and relevant information based on the latest medical knowledge and the specific characteristics of the patient using the medication.
When discussing any medication, it's important to share your medical history and any existing medical conditions or allergies with your healthcare provider to ensure safe and appropriate usage. Additionally, they can help you understand any potential interactions with other medications you might be taking and provide guidance on how to use the medication correctly.
