The Importance of Corneal and Tear Examinations

Proper contact lens prescription relies heavily on understanding the condition of your cornea and tears. A variety of tests are necessary to ensure the right choice of lenses. In this post, we'll explain why corneal shape and tear tests are so important.

Corneal Shape Examination 👁️‍🗨️

Measuring the flattest and steepest curvatures of the cornea is essential. This helps determine the corneal curvature values and assess any aspherical shapes. Tools like the keratometer or autokeratometer can easily measure the central part of the cornea but may miss the details of the peripheral areas. However, with corneal topography, we can accurately assess the entire cornea, allowing for precise RGP lens prescriptions.

Tear Examination 💧

If your eyes don’t produce enough tears, contact lenses can become uncomfortable. Tests such as tear meniscus measurement or Schirmer test help determine if there is dry eye syndrome. If the tear break-up time is under 10 seconds, it's advised to avoid extended lens wear, and if it’s under 5 seconds, it’s best to avoid lenses altogether.

👓 Binocular Function and Accommodation

Wearing contact lenses can significantly impact your vision, especially for those with myopia or hyperopia.

For Myopia 🔍

When switching from glasses to contact lenses, the change in vertex distance means that more accommodation is required to see close objects. Additionally, when wearing glasses and looking at something close, the eyes converge less due to the base-in prism effect. For individuals in their early 40s with moderate or higher myopia, this can result in earlier-onset presbyopia when switching to contact lenses.

For Hyperopia 🔭

In contrast, hyperopic individuals may experience increased convergence when wearing glasses due to the base-out prism effect, making it harder to focus. In cases where prism correction is required, contact lenses may not be the ideal choice.
