The Anatomy of the Eye and Lasik

Lasik eye surgery has become a great option for those who want to improve their vision. Here is a description of how your vision is corrected and what eye conditions benefit most from this impressive procedure.

Lasik and the Anatomy of Your Eye

Most Lasik procedures involve working on the cornea of the eye. Positioned in front of the iris and pupil, this small structure acts like a window. Light passes through the corneal structure and the shape of the cornea determines how the light is bent. A misshapen cornea will bend light abnormally so that it is not properly focused on the retina of your eye. With Lasik surgery, the misshapen cornea is fixed so that light is properly focused on your retina, ensuring crisp and clear vision.

Visual Conditions that Lasik Corrects

There are four primary visual issues that you might consider having Lasik surgery for. Each issue entails a different variation of Lasik.

  • Farsightedness: This condition is characterized by difficulty seeing up-close objects. When surgeons are performing Lasik for this condition, they are looking to add more of a curve to your cornea. They target the central corneal tissue with the laser to enhance the curve’s profile. They also remove corneal tissue to ensure proper light focus on the retina.
  • Nearsightedness: This condition is characterized by difficulty seeing far away objects. To use Lasik for this condition, surgeons need to remove inner layer tissue from the cornea. A laser is used to remove an exact amount of tissue to flatten an excessive curvature to reshape the cornea.
  • Presbyopia: This is common in middle age and affects your ability to focus on nearby objects. While Lasik is not commonly used for this, the procedure is exactly like the one used for nearsightedness.
  • Astigmatism: This condition is characterized by your cornea looking more like a football than a smooth tennis ball. This prevents light from properly focusing on the retina, resulting in blurry vision. Surgeons flatten the corneal curve, making it more spherical for proper light refraction.

For Long-lasting Results
