Understanding Refractive Errors and How LASIK Corrects Them

Refractive errors are some of the most common vision problems affecting people in Philadelphia and around the world. They occur when the eye cannot properly focus light on the retina, leading to blurry or distorted vision. Fortunately, LASIK surgery offers an effective solution to correct these errors, allowing patients to enjoy clear, sharp vision without glasses or contact lenses.

At Columbus LASIK Vision, we specialize in diagnosing refractive errors and providing personalized LASIK treatment to meet the unique needs of each patient. Let’s dive deeper into refractive errors, how they occur, and how LASIK can correct them.

What Are Refractive Errors?

Refractive errors occur when the shape of the eye prevents light from focusing directly on the retina. This can happen due to:

• The length of the eyeball (too short or too long).
• The shape of the cornea (the clear front surface of the eye).
• The aging of the eye’s lens.

These issues cause light to bend improperly, resulting in blurry vision at various distances.

Common Types of Refractive Errors

1. Nearsightedness (Myopia)

What is it? Nearsightedness occurs when the eyeball is too long, or the cornea is too curved. Light focuses in front of the retina instead of directly on it, causing distant objects to appear blurry while close objects remain clear.

Symptoms:

• Difficulty seeing objects far away (e.g., road signs, a classroom board).
• Squinting to see clearly. • Headaches or eye strain from focusing on distant objects.

How LASIK Corrects It: LASIK reshapes the cornea to reduce its curvature, allowing light to focus directly on the retina for clear distance vision.

2. Farsightedness (Hyperopia)

What is it? Farsightedness happens when the eyeball is too short, or the cornea is too flat. Light focuses behind the retina, making close-up objects appear blurry while distant objects are often clearer.

Symptoms:

• Blurry vision when reading or performing tasks up close.
• Eye strain and headaches after prolonged near work.
• Difficulty focusing on nearby details.

How LASIK Corrects It: LASIK steepens the cornea’s shape, allowing light to bend properly and focus on the retina for clearer near vision.

3. Astigmatism

What is it? Astigmatism occurs when the cornea has an irregular, football-like shape instead of a round shape. This irregularity scatters light, leading to blurred or distorted vision at all distances. Symptoms:

• Blurry or distorted vision for both near and far objects.
• Difficulty seeing fine details.
• Eye strain, headaches, or squinting to see clearly.

How LASIK Corrects It: LASIK reshapes the cornea into a more regular, spherical shape, ensuring light focuses evenly on the retina for clearer vision.

4. Presbyopia

What is it? Presbyopia is an age-related condition that usually begins in the mid-40s. It occurs when the eye’s lens loses flexibility, making it harder to focus on close-up objects.

Symptoms:

• Difficulty reading small print, such as books or phone screens.
• Holding reading materials farther away to see clearly.
• Eye strain when doing close-up tasks.

How LASIK Addresses It: While LASIK does not reverse presbyopia, Monovision LASIK can help. One eye is corrected for distance vision, and the other is adjusted for near vision, reducing the need for reading glasses.

How Does LASIK Correct Refractive Errors?

LASIK (Laser-Assisted In Situ Keratomileusis) is a quick, effective procedure that reshapes the cornea to allow light to focus properly on the retina. Here’s how it works:

1. Creating the Corneal Flap: A thin flap is created on the cornea using a femtosecond laser.
2. Reshaping the Cornea: An excimer laser gently removes microscopic amounts of tissue to correct the cornea’s shape.
3. Repositioning the Flap: The flap is placed back in its original position, where it heals naturally without stitches.

The result is improved vision with minimal discomfort and a fast recovery.
