I have myopia and getting floaters in my left eye after YAG laser capsulotomy. Why?

Hello doctor,

I am a 38-year-old male. I have a family history of myopia and cataract. I had myopia since early childhood. I developed a cataract in both my eyes at the age of 32 and had them operated upon followed by an IOL in both the eyes. Soon after, in the same year, I developed opacification in my left eye and my doctor conducted a YAG laser capsulotomy to have the problem corrected. In this context, I wish to mention that I see several floaters in my left eye. Six years following my cataract surgery and IOL transplantation, I developed a blurry vision and a bubble in my right eye and my doctor diagnosed opacification in my right eye and conducted a YAG laser capsulotomy. Following the capsulotomy, my vision improved but the bubble is still there and it is causing a scattering of light vision in my right eye, more prominent when I am tilting my head towards the right. My doctor says that the anatomical capsule holding on to the IOL in my right eye has weakened over the years and is causing the IOL to move inside my eye. This movement of the lens, coupled with the formation of the bubble is causing the scattering of light vision in my right eye. The doctor said that the bubble should disappear within or around six weeks of the capsulotomy. He also said that if the IOL gets dislodged or its movement causes too much of discomfort, then the solution would be to have the lens removed and replaced with an IOL with its own capacity to hold on to its position without depending on the anatomical capsule to hold it in its place. My questions are: What is the reason for the appearance of the bubble in my right eye? As the doctor said, will it disappear within or around six weeks of the capsulotomy? Will I have a better vision if I go for a replacement of the IOL since it is moving? Is there a way to reduce floaters in the eye and to treat macular degeneration of the eye?
