Well, yes, cataract surgery can lead to it. A macular pucker is a term that refers to scar tissue that has formed on the macula, the part of the retina that provides sharp, central vision. As we know that there are some factors which can lead to macular pucker, such as retina injury. When you have cataract surgery, it is possible to have microscopic damage to the retina's surface. When this happens, the retina begins healing the damaged area and forms scar tissue, or an epiretinal membrane, on the surface of the retina. In that way, a macular pucker may occur. And then, blurry vision and vision loss are two of the most common symptoms. Other possible symptoms may include mildly distorted vision, difficulty seeing fine detail and reading small print. So just be careful about it. For your situation, you should protect your eyes after the surgery by wearing eye patch.
