Refractive surgery at Sharda Care - The Healthcity offers solutions for common vision problems like near-sightedness, far-sightedness, astigmatism, and presbyopia. These procedures aim to reshape the cornea or implant a lens in the eye, ultimately focusing light correctly on the retina for clearer vision.

Refractive errors are caused by irregularities in the shape of the cornea or abnormalities in eye length, causing blurred vision. The cornea, responsible for bending and focusing light waves, may not properly direct light onto the retina, resulting in blurred images. These errors can affect healthy eyes and manifest in four main types:

Near-sightedness (myopia): Close objects are clear, but distant ones are blurry due to the eye being too long or the cornea excessively curved, causing images to focus in front of the retina.

Far-sightedness (hyperopia): Distant objects are clear, but close ones are blurry because of a shorter eye or a too-flat cornea, causing images to focus behind the retina.

Astigmatism: Blurred vision at any distance results from irregularly shaped corneas, lenses, or both, preventing sharp focus on the retina.

Presbyopia: Commonly known as ageing eyes, this condition reduces the eye's ability to change focus due to age, typically occurring around ages 40-50. While refractive surgery can enhance distance vision, it may not fully address near-vision problems associated with presbyopia.
