Question

An artificial lens is implanted in a person's eye to replace a diseased lens. The distance between the artificial lens and the retina is 2.72 cm. In the absence of the lens, an image of a distant object (formed by refraction at the cornea) falls 5.51 cm behind where the implanted lens would be inserted. The lens is designed to put the image of the distant object on the retina. What is the power of the implanted lens? Hint: Consider the image formed by the cornea to be a virtual object I keep getting 24.614 and im being told it is wrong! what am i doing wrong here? Thanks.

Explanation / Answer

This is not an easy question. It would seem that if you are blind in one eye and have the wrong power in the other, that your main goal should be to achieve good vision in the operated eye. There are different reasons for the implanted lens to be of the wrong power. Were the calculations wrong? Did the nurse give the wrong lens? Were there complications? It sounds like there was some problem the first time since normally the lens is implanted when the cataract operation is done. Your best option at this time is to find a highly qualified cataract surgeon to give you a second opinion. If he agrees that lasik would solve the problem, then that would be preferable to operating on the inside of your only eye for a third time. You could also just use glasses with the compensating power. If glasses do not work then there is some problem other than the power of the IOL that is affecting your eye.
