Defeating Astigmatism & Keratoconus with Corneal Topography in Clinton
Gone are the days of one-size-fits-all contact lenses! In the ever-evolving world of eye care, technology has unlocked the potential for highly personalized solutions that offer clear and comfortable vision for people with hard-to-fit eye conditions such as astigmatism and keratoconus.
Understanding Corneal Topography
The cornea, the clear front part of your eye, assists with focusing light on the retina, allowing you to see. However, when the cornea faces challenges — such as being irregularly shaped due to hard-to-fit conditions like astigmatism or keratoconus — this can make the task more difficult. An irregularly shaped cornea causes distorted vision, making it difficult for a patient to achieve clear vision with regular soft contact lenses. That's where corneal topography steps in.
Corneal topography isn't your typical eye exam; it's a non-invasive diagnostic technique that provides a detailed map of your cornea's curvature. This map is like a blueprint for your eye, allowing eye doctors to assess your cornea's shape, size, and overall health. By understanding the intricacies of your cornea, our eye doctor can unlock personalized solutions like comfortable contact lenses that enhance your vision and improve your overall eye health.
The Importance of Contact Lens
Corneal Topography
Contact lens corneal topography takes the precision of traditional corneal topography a step further by focusing on the unique requirements of contact lens wearers. This technology allows eye care professionals to:
- Customize Contact Lenses: By accurately mapping your cornea's surface, your eye care provider can customize contact lenses that fit perfectly, ensuring maximum comfort and clarity.
- Detect Irregularities: Corneal topography can identify irregularities or conditions that may impact your ability to wear contact lenses comfortably.
- Optimize Correction: It helps determine the most suitable contact lens type, power, and fit, particularly for challenging cases like astigmatism or complex prescriptions.
Advantages of Customized Contact Lenses
Customized contact lenses, created using data from corneal topography, offer several advantages:
- Enhanced Comfort: Custom-fit lenses minimize discomfort, making them ideal for extended wear.
- Sharper Vision: Precisely fitted lenses provide crisp, clear vision, reducing glare and halos.
- Improved Eye Health: Properly fitted lenses reduce the risk of complications like dryness, irritation, and infection.
- Reduced Lens Rotation: Custom lenses tend to stay in position better, ensuring consistent vision throughout the day.
Who Can Benefit from Corneal Topography?
Corneal topography and customized contact lenses are beneficial for a wide range of individuals, including those with:
- Astigmatism
- Keratoconus
- Post-surgery corneal irregularities
- Complex prescriptions
- Dry eye syndrome
- Discomfort or redness with conventional lenses
- A desire for more comfortable and sharper vision with contacts
The Corneal Topography Process
The process of corneal topography is straightforward and painless:
- Sit in front of a specialized instrument.
- Our technician will instruct you to focus on a target like a light.
- The instrument will project rings or patterns onto your cornea.
- It will capture data points to create a detailed map of your cornea's surface.
- The entire process typically takes only a few minutes for each eye.
Scleral Lenses
These lenses have a larger diameter, ensuring that they vault over the cornea and rest on the white part of the eye (sclera). This design provides a stable fit, reducing the potential for movement on the eye's surface. The space between the lens and the cornea is filled with a soothing saline solution, making them exceptionally comfortable to wear.

Choosing the Right Contact Lenses
Once the corneal topography data is collected, your eye care provider will work with you to select the most appropriate contact lenses. Customized options may include:
- Orthokeratology (Ortho-K): These advanced gas-permeable lenses reshape the cornea overnight, offering clear vision during the day without lenses.
- Soft Lenses: Customized soft lenses provide superior comfort and vision correction for everyday wear.
- Toric Lenses: They feature different powers in different meridians of the lens, aligning with the astigmatic axis in your eye. This targeted correction ensures light is focused correctly on the retina, providing clear and stable vision.
When recommending lenses, your eye care professional will consider your visual needs, lifestyle, and comfort preferences.
