I am not sure, if i understood your question properly. But, let me try to give a generic guideline for Diabetics.
If you are diabetic, please follow the bellow guideline.
- Keep strict control of your blood sugar level. This will delay development of eye complications.
- Yearly eye check-up and consultation by an Ophthalmologist without fail.
- If any visual problem ( like blurring of vision or reduced vision ) develops, consult with an Ophthalmologist immediately.
Development of Cataract can never be prevented completely. But a good sugar control can help in delaying that.
