At Saddleback Eye Center, we believe in delivering only the best care for your eyes. Using advanced LASIK technology, our esteemed surgeon Dr. Manger has helped over 94,000 patients see the world anew.

What is LASIK?

LASIK, an acronym for Laser-Assisted in Situ Keratomileusis, is a surgical procedure used to correct vision in nearsighted, farsighted, or astigmatic people. The procedure reshapes the cornea, the clear front part of the eye, to allow light entering the eye to be correctly focused onto the retina for sharper vision.

How LASIK Reshapes the Future of Vision Correction

LASIK is more than just a procedure — it represents a significant leap forward in the world of vision correction. So how does it reshape the future of vision correction?

Precision: LASIK uses an advanced Excimer laser to accurately and effectively reshape the cornea, addressing the root cause of refractive errors.

Quick Recovery: Unlike traditional surgeries, LASIK offers minimal discomfort and rapid vision recovery, often within 24 hours.

Long-lasting Results: LASIK provides permanent changes to the cornea, resulting in long-lasting vision correction.

LASIK’s precise and advanced technology, swift recovery times, and long-lasting results solidify its standing as a revolutionary development in vision correction. This procedure has reshaped and will continue redefining the future of corrective eye surgery, offering a beacon of hope for millions worldwide with refractive errors.

The Science Behind LASIK Surgery

LASIK involves using a laser to reshape the cornea, improving its focusing power. The science underpinning this is founded on understanding how light enters the eye and is refracted (or bent) by the cornea to form an image on the retina at the back of the eye.

Corneal Reshaping: The Key to Visual Clarity

The cornea’s shape significantly influences our vision. As such, a perfectly shaped cornea will refract light onto the retina in a way that produces clear images. However, if the cornea is too steep, too flat, or irregular (as in astigmatism), the light gets misdirected, causing blurry or distorted vision. By modifying the cornea’s shape, LASIK helps correct these refractive errors.

The Role of Laser Technology in LASIK

Laser technology is integral to LASIK surgery, and our surgeon at Saddleback Eye Center, Dr. Manger, uses state-of-the-art lasers to ensure precision and safety. The Excimer laser is used to reshape the cornea, removing microscopic layers of tissue. It is a cool laser, meaning it doesn’t burn tissue but breaks molecular bonds, resulting in precise, controlled removal.

Customized LASIK: Tailoring the Procedure to Individual Needs

Each eye is unique. Therefore, LASIK surgery must be customized to the individual patient’s needs. At Saddleback Eye Center, we use Wavefront technology to create a detailed map of your eye, capturing its unique irregularities. This map guides the laser during surgery, allowing for highly customized treatment.

Understanding Astigmatism

Astigmatism is a common type of refractive error. It is a condition where the cornea, the eye’s front surface, isn’t perfectly round but is more oval-shaped, like a football. This irregular shape causes light to focus on more than one point in the eye, leading to blurred or distorted vision.

The Impact of Astigmatism on Vision

Astigmatism profoundly affects visual clarity, leading to blurred or distorted vision. This stems from the cornea’s irregular shape that hinders light from focusing correctly on the retina. Disrupting this focus renders images blurry at all distances, a disconcerting experience for anyone going about their daily tasks.

Common Symptoms of Astigmatism

In addition to blurred vision, astigmatism may present various symptoms, including difficulty with night vision, eye strain, headaches, and constant squinting. It’s crucial to note that these symptoms are common in other eye conditions, which is why a comprehensive eye exam by an expert like Dr. Manger at Saddleback Eye Center is critical in diagnosing astigmatism.

The Challenges of Living with Untreated Astigmatism

Living with untreated astigmatism can be challenging. Simple tasks such as reading, driving, or even recognizing faces can become difficult. Moreover, constant eye strain can lead to headaches and further visual complications. Therefore, it’s crucial to seek professional help if you experience any symptoms of astigmatism.

Correcting Astigmatism with LASIK

As a trailblazer in vision correction, LASIK offers a reliable solution for astigmatism. By reshaping the cornea to a more normal curvature, LASIK can correct the refractive errors caused by astigmatism, providing patients with clearer vision.
