Is there a cure for myopia and hyperopia?

From my understanding, myopia and hyperopia (as well as certain forms of astigmatism) are caused by an irregular shape of the eyeball. If this is so, have scientists found a way to reshape the eyeball and cure these conditions? Are there other implications that conditions like myopia and hyperopia cause that make this difficult? What relevant research is being done today?

I developed myopia and a very young age and had it get increasingly worse, up until the point where I can not see anything more then a few inches away clearly without glasses. I've always been curious about this. I don't mind wearing contacts or glasses all the time, but it would be nice if there was a way to actually cure this!

A person developing a refractive error (myopia/hyperopia/astigmatism) is mainly due to their genetics.
However, it is still not fully understood what causes people genetically susceptible to refractive errors to develop them while others do not. That is where the environmental factors apparently come into play. This issue is very complex and as of now there is no concrete evidence to actually prove any theory 100 percent. The only thing that has been proven is that genes are involved in developing refractive error and many other factors are involved! Scientists believe that people who develop refractive error because they are genetically susceptibility also combined with tissue alterations influenced by environmental factors. Since the development of refractive errors is still not fully understood, at this time there still is no "cure". You cannot cure something that is not fully understood.
Laser eye treatments can be preformed to correct vision and obviously contact lenses and glasses can be worn to correct vision, but at this time there is no actual cure or way to prevent refractive errors.
Most of the research that I have seen done involves myopia and focuses mainly on what causes a person to develop it.
Here is some information I have dug up from some myopia studies if you are interested:
"A study of 506 pairs of twins (both identical and non-identical) confirmed an earlier study by the same group that genes are by far the most important factor with a heritability of 89% - environmental factors only accounted for 11%. "
Research is still not conclusive on this matter so as it stands nearsightedness is predominately genetic, since even small deviations from normal structure cause significant refractive errors, it may be difficult to single out any specific genetic or environmental factor as their cause.
"Only 6%-15% of children with myopia come from families in which neither parent is myopic. In families with one myopic parent, 23%-40% of the children develop myopia. If both parents are myopic, the rate rises to 33%-60% for their children. One American study found that children with two myopic parents are 6.42 times as likely to develop myopia themselves as children with only one or no myopic parents. The precise interplay of genetic and environmental factors in these family patterns, however, is not yet known."

Lasik surgery is effective for treating myopia for some people. From http://eye-care.in/myopia.html

yes i agree u, why dont they reshape our eyeballs? we are all teached that "myopia and hyperopia (as well as certain forms of astigmatism) are caused by an irregular shape of the eyeball".

maybe because its harder than doing lasic surgery :))

There is no CURE for myopia or hyperopia or astigmatism, per se. Laser surgery and other forms of refractive surgery can reshape the cornea to off-set the refractive error caused by the anatomy of your eye but to date, there are no procedures available that will actually change the anatomy of the eye...perhaps one day!
