You're like to have to wear glasses for some activities, although there's no doubt that it's better to replace cataracts than not. Unless you get a bifocal lens replacement, and most insurance companies in the US aren't going to pay for it, you will find that you can have either great long-distance vision or great up-close vision, but not both. The bad news is that this process can take up to a year.Īnd when it comes to cataract surgery, many people aren't happy with the results if they are already farsighted. The good news about this wavy line is that it will eventually go away even without further surgical intervention. There are more frequent complications with oil than with air. As the eye regenerates vitreous fluid, the bubble will move to the top of the eye, and the boundary between the natural fluid and the injected air or oil will appear wavy. This bubble isn't the same density as the eye's naturally occurring fluids. An air bubble slowly dissipates on its own, while an oil bubble has to be removed in a separate procedure after the scar has healed. This process ideally increases pressure inside the eye just enough, usually, to keep the retina in contact with the choroid until scar tissue can make the bond permanent. This procedure is known as pneumatic retinopexy. To hold the retina in place while the scar is forming, the surgeon may remove the vitreous fluid in the eye and replace it with a bubble of an oil called sulphahexafluoride (SF6), air, or both. You may have a permanent blind spot at each site of reattachment, but you could have no vision at all without the treatment. Retinal detachment is treated with laser or cryotherapy (with a freezing proble) to create a small scar that will reattach it. These are most common in people under the age of 40.
