How long does a cataract surgery patient have to use eyedrops and why? Antibiotic eyedrops are used after cataract surgery to prevent infection and steroid and NSAID (non-steroidal anti-inflammatory drug) eyedrops are used to reduce and eliminate inflammation. Typically, the antibiotic drops are used for about a week, while the anti-inflammatory drops are used three to six weeks or longer in some cases.
1 Unlike cable, fiber is not easily affected by water. Fiber-optic technology is practically weather-proof.  Fiber optics use light to transmit information, so the networks can transmit more information between the central office and the home - faster. This means faster fiber-optic Internet speeds, sharper fiber-optic television and clearer calls with fiber-optic home phone.
Over the last 20 years or so, fiber optic lines have taken over and transformed the long distance telephone industry. Optical fibers are also a huge part of making the Internet available around the world. When fiber replaces copper for long distance calls and Internet traffic, it dramatically lowers costs. To understand how a fiber optic cable works, imagine an immensely long drinking straw or flexible plastic pipe. For example, imagine a pipe that is several miles long. Now imagine that the inside surface of the pipe has been coated with a perfect mirror.
