Keratoconus

Keratoconus is a progressive eye condition that can significantly impact vision and quality of life. Early detection and treatment are crucial for maintaining clear vision and preventing complications. At Eyes On Dallas, Dr. Mai Nguyen specializes in diagnosing and managing keratoconus, offering advanced solutions to help patients see clearly and comfortably.

What Is Keratoconus?

Keratoconus is an eye disorder that causes the cornea—the clear, dome-shaped front surface of the eye—to thin and gradually bulge outward into a cone shape. This irregular shape distorts light entering the eye, leading to blurred and distorted vision. The exact cause of keratoconus is not fully understood, but genetic factors and environmental influences, such as excessive eye rubbing and prolonged UV exposure, may contribute to its development.

Keratoconus often begins during the teenage years or early adulthood and can progress over time. In its early stages, vision correction with glasses or soft contact lenses may be effective, but as the condition advances, more specialized treatment options are required.

Recognizing the Signs and Symptoms of Keratoconus

Keratoconus can develop gradually, making early detection critical. Common signs and symptoms include:

• Blurred or distorted vision

• Increased sensitivity to light and glare

• Frequent changes in eyeglass or contact lens prescriptions

• Difficulty seeing at night

• Halos or ghosting around lights

• Eye strain or discomfort

If you experience any of these symptoms, scheduling an eye exam is essential for an accurate diagnosis and appropriate treatment.

The Importance of Regular Eye Exams

Regular eye exams play a crucial role in detecting keratoconus before it progresses to advanced stages. Since the early symptoms can mimic other vision problems, such as astigmatism, a comprehensive eye exam with corneal topography and tomography is necessary to accurately diagnose keratoconus. Dr. Nguyen uses advanced diagnostic technology to assess the shape and thickness of the cornea, identifying keratoconus in its earliest stages.

During an eye exam, she will perform:

• Corneal Topography – A detailed map of the cornea’s surface to detect irregularities.

• Pachymetry – A measurement of corneal thickness to assess thinning.

• Refraction Testing – Determines the best corrective prescription for vision clarity.

With a thorough evaluation, she provides personalized treatment plans tailored to each patient's specific needs.

Specialty Contact Lens Options for Keratoconus

Specialty contact lenses designed for irregular corneas can offer improved comfort and clearer vision. Dr. Nguyen fits and prescribes the following advanced contact lens options:

• Rigid Gas Permeable (RGP) Lenses: RGP lenses provide sharper vision by maintaining a smooth, regular surface over the cornea. These lenses are smaller in diameter and rest directly on the cornea, improving vision clarity for many keratoconus patients.
  
  

• Scleral Lenses: Scleral lenses are larger than traditional contacts and vault over the cornea, resting on the white part of the eye (sclera). These lenses create a fluid-filled chamber that hydrates the cornea and provides superior vision correction and comfort, making them ideal for advanced keratoconus.
  
  

• Hybrid Lenses: Hybrid lenses combine a rigid center for clear vision with a soft outer skirt for enhanced comfort. They provide the benefits of both RGP and soft lenses, making them a great option for patients who struggle with the feel of rigid lenses.

Dr. Nguyen works closely with each patient to determine the best lens option based on their corneal shape, lifestyle, and visual needs.
