Once you are outside of the immediate postoperative period of about 2 weeks, it is is generally safe to return to regular activities. These may include:
- Strenuous athletic activity
- Outdoor activities, such as golf
In our practice I've had patients climb K2 and dive the great barrier reef a month after the procedure. Other extremes that you are mentioning like radiation or heat (like working as a glass blower or at a steel mill) are not recommended with or without the ICL.
