Understand Your Eyes — The Most Complex Organ in Your Body
Before considering LASIK, understand how your eye works. The human eye processes 36,000 pieces of information every hour. Here's what makes it tick — and why LASIK is so effective.

The Cornea — Where LASIK Works
The cornea is the clear, dome-shaped front surface of your eye. It's responsible for about 65-75% of your eye's total focusing power. LASIK works by precisely reshaping the cornea to correct how light enters your eye.
- Average corneal thickness: 540 microns (thinner than a credit card)
- The cornea has 5 layers — LASIK reshapes the stromal layer
- It heals quickly because of its rich nerve supply
- Modern lasers can sculpt with 0.25 micron accuracy
How Vision Problems Occur
Refractive errors happen when the shape of your eye doesn't bend light correctly. The cornea and lens must focus light precisely on the retina. When they don't, you see blurry images.
- Myopia (nearsightedness): Eyeball too long, light focuses in front of retina
- Hyperopia (farsightedness): Eyeball too short, light focuses behind retina
- Astigmatism: Irregularly shaped cornea causes distorted vision
- Presbyopia: Age-related loss of near focusing (after age 40)
The Retina — Your Internal Camera
The retina contains over 130 million photoreceptor cells that convert light into electrical signals. These signals travel through the optic nerve to your brain, where they're interpreted as images. LASIK ensures that light is focused precisely on the retina for the clearest possible vision.
