Patients often come to our eye care center in Pune, India, and ask us “How do I know if I need Laser Eye Surgery?” The short answer is, if you are experiencing a refractive error. Refractive errors are caused by rays of light entering the eye that are not able to focus precisely on the retina.
A myopic eye is longer than normal and the cornea is steeper, so the light rays focus in front of the retina. This causes close objects to look clear but distant objects appear blurred.
Hyperopia causes are typically genetic. A hyperopic eye is too short and the cornea is too flat, so the rays of light focus behind the retina. This causes distant objects to look clear but near objects appear blurred.
ASTIGMATISM (DISTORTED VISION):
The incoming light rays are unable to focus at a common point within the eye. This causes distorted or blurred vision for both near and far objects. S normal cornea is round and smooth. With astigmatism, the cornea curves more in one direction than in the other. Astigmatism can occur in combination with myopia or hyperopia.
