Can astimatism be corrected by a converging lens?
No. Astigmatism must be corrected by a distorting lens which reverses the distortion of the eye.
Does positive meniscus lens correct myopia?
Nope, a negative meniscus lens corrects myopia. Positive meniscus corrects hyperopia.
What is pseudophakic?
When an eye is pseudophakic, the natural lens has been surgically removed and replaced by an artificial lens - an implant. These days the implant procedure is undertaken as soon as the opaque lens (cataract) is removed. Before this combined procedure became widely popular, with the introduction of artificial lenses, the natural lens was removed and the vision was corrected with spectacles and contact lenses- the eye being known as aphakic. *Please read senile cataracts, traumatic cataracts and congenital cataracts.
What are some surgical treatments for hyperopia?
One approach is to implant corrective contact lenses behind the patient's iris. Another approach, called laser in situ keratomileusis (LASIK), is to surgically increase the curvature of the eye's existing cornea or lens using a laser.

What is the antonym of myopic?
The opposite to myopic/myopia is HYPEROPIC/HYPEROPIA. Myopia is also known as short sightedness or near sightedness. Hyperopia is also known as long sightedness or far sightedness. A myopic eye focuses the image before it reaches the retina at the back of the eye. This is because the eye is too strong. A myopic eye will find it easier to focus on a close up object rather than a far away object. A myopic eye needs to be corrected with a minus/negative powered prescription lens (-). A hyperopic eye focuses the image after/behind the retina as a hyperopic eye is too weak. A hyperopic eye will have problems focusing on close up objects and in some cases it won't be able to focus at any distance. A hyperopic eye will be corrected with a plus/positive powered prescription lens (+).
