I have undergone retinal laser surgery (for a tear) and I am going to serve in the Navy (mandatory service for 6 months)?
Hello Doctor: Over the past 10 years, I have undergone retinal laser surgery (for a tear) due to high myopia.
In February, I will be joining the Navy (mandatory service), and part of the training involves swimming (breaststroke) and diving (vertical diving from a height of about 2-3 meters, entering the water feet first, followed by the head, and then the eyes, but surfacing within a few seconds).
I have already gone to the Veterans General Hospital for a re-examination and obtained a certificate (the doctor noted to avoid "strenuous exercise," but is swimming and diving generally considered "strenuous exercise"? Also, after retinal laser surgery (for a tear), is it safe to swim and dive? If it is not safe, and if the medical officer deems swimming and diving acceptable, given the mandatory nature of military training, how can I avoid causing new tears (I have seen other doctors suggest wearing goggles to reduce the impact on the eyes)? I do not want my service to affect my future vision (risk of retinal detachment) and cause lifelong suffering.
I kindly request your guidance.
Thank you.

Although diving poses some risks for retinal tears, it is not contraindicated.
There are no specific regulations regarding retinal tears in military service examinations.
It is advisable to remain vigilant and, if any abnormalities occur, it is best to undergo a thorough examination for confirmation.

More Info
After undergoing retinal laser surgery for a retinal tear, it’s understandable to have concerns about participating in activities such as swimming and diving, especially given your upcoming commitment to Navy service. The nature of your surgery and the potential risks associated with physical activities are critical factors to consider.
First, it’s important to clarify what is meant by "intense" or "vigorous" activities. Swimming, particularly in a controlled environment, is generally considered a low-impact exercise. However, diving, especially from heights, can introduce risks due to the sudden pressure changes and the potential for impact on the water surface. The concern with diving is that the force of hitting the water can create a jarring effect on the body, which may not be ideal for someone who has had recent eye surgery.
Your doctor has advised against "intense exercise," which could include activities that involve sudden movements or high-impact forces. While swimming may be less risky, diving could be more problematic. The recommendation to avoid vigorous activities is likely a precaution to prevent any strain on the eyes, which could lead to complications such as retinal detachment or the formation of new tears.
If you are cleared for swimming but advised against diving, it is crucial to adhere to those guidelines. If you find yourself in a situation where you must participate in diving, consider the following precautions:
1. Use Protective Gear: Wearing goggles can help shield your eyes from the impact of water and reduce the risk of water entering your eyes, which could cause irritation or complications.
2. Communicate with Your Superiors: If you have medical documentation stating that you should avoid vigorous activities, present this to your commanding officer. It is essential to advocate for your health and safety, especially when it comes to your vision.
3. Monitor Your Symptoms: Pay close attention to any changes in your vision or discomfort during or after swimming or diving. If you experience any unusual symptoms, seek medical attention immediately.
4. Gradual Return to Activities: If you are cleared for swimming, start slowly and gradually increase your activity level. Avoid diving until you have a definitive clearance from your eye doctor.
5. Regular Eye Check-ups: Continue to have regular follow-ups with your ophthalmologist to monitor your eye health. If any issues arise, they can provide guidance on activity restrictions.
In summary, while swimming may be permissible after retinal laser surgery, diving poses additional risks that should be approached with caution. Always prioritize your eye health and follow your doctor's recommendations. If there is any doubt, it is better to err on the side of caution and avoid activities that could jeopardize your vision. Your future well-being is paramount, and taking these precautions can help ensure that you maintain your eyesight throughout your service and beyond.
