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.
Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data rates) than wire cables.ptical fiber is also used in imaging optics. A coherent bundle of fibers is used, sometimes along with lenses, for a long, thin imaging device called an endoscope, which is used to view objects through a small hole. Medical endoscopes are used for minimally invasive exploratory or surgical procedures.
