Learning about Cataracts
I am sure you have heard about a family member experiencing cataracts or have had a patient that was diagnosed with it. It is a very prevalent age-related eye condition that significantly impacts vision and quality of life. Understanding cataracts, early signs, later signs, and management enables nurses to educate patients, provide support during the pre and post operative period, and promote preventative measures for better eye health.
My mom had cataract surgery a few years ago. I can remember her having a hard time seeing anything due to her blurred vision. After she saw her eye doctor and had surgery, it was a complete 360. She didn’t realize just how much it affected her before. After surgery, she used eye drops for several weeks and has never had an issue with her sight since. .png?width=1200&height=630&name=nclex%20review%20for%20angina%20(2).png)
