Hi. I'm online and happy to answer your question today.
While the lens does not, per se, protect the retina, it is in front of it and serves to focus incoming light on the retina so you can see.
The replacement lens is designed to filter out UV light and, as such, helps to protect the retina. Cataract surgery does not involve messing with the retina at all and you do not need to worry about your retina when you have your cataract surgery in the vast majority of casess.
Wow! These are a lot of questions......let me go through them in order from this point on:
The lens used to replace your cataract is up to you. The is the "usual" monofocal lens and the newer multifocal lens. They are both good. Which one you use is a personal choice. Talk to your surgeon about your options.
The monofocal lens should not cause a halo effect.
There is no panic. It does not hurt to wait to have your cataract removed. It is not an emergency.
The replacement lens will not damage your retina.
The cheap lens is just different then the expensive one. I, personally, would get the cheap one if I was having surgery.
Is there anything else you would like to discuss at this point or have all your questions been answered to your satisfaction?
I hope this information was helpful for you. But I do work for tips so I want to make sure you are happy with me before rating me. If you have another question on this or a related issue feel free to fire away. And please let me know if the rating system gives you any troubles. Thanks in advance, Dr. Rick MD FACS
The more expensive one operates with concentric circles and is implanted in the same way as the cheap one.? Do the concentric circles encourage the eye muscles to atrophy? Because of the cataract my doctor cannot see the retina and is making a judgment that it is in a state of deterioration. He does not believe that each eye should have a different lens. I am reading otherwise. The longer view is what I'm interested in. My right eye is in good shape I doubt that the left eye is any different. Will eye muscles deteriorate with either implant? You like the simpler why?
I am trying to select between multifocal lenses and mono focal lenses. I am not sure however from my research it appears that multifocal lenses operate with concentric circles, is that true? Also multifocal lenses cause eye muscles to atrophy, is that true? Each lens has its positive and negative features, what are they. My eyes are not that bad and with the Mono focal lenses will the eye muscles improve?
In addition to your advice I looked on the Internet. Your advice helped me search the Internet. It appears to me that if my eyes were bad and I was old that the multifocal would be better. Well I am old more or less at 71 but I am in good health and the Mono focal lens in my right eye works well. The muscles in my eye allow both near and far vision. Of course everyone time I talked to anyone who were given glasses as a child always state they did not know how bad their eyes were. It seems to me that with the multifocal these muscles would atrophy. I read something about it on the Internet however you can't believe everything you read in the newspapers or Internet. I hope I'm making the right decision
