This study is about epiretinal membrane (ERM), a condition where a thin layer forms on the retina, the light-sensitive part at the back of your eye. This can cause vision problems like distortion or blurriness. A vitrectomy is a surgery to remove this layer. Some doctors suggest waiting to do the surgery until vision gets worse, but this study wants to find out if doing the surgery sooner is better for vision. The study also wants to learn more about which patients do better if they wait or get the surgery right away.

Key Points for Participation:

• Participants must be at least 45 years old and have certain vision conditions.
• The study will compare immediate surgery to waiting, and it will look at vision changes over time.
• Participants should not have other serious eye conditions or recent eye surgeries.
