What is the recommended approach if a high minus lens, such as -7, is riding high on the cornea?

When a high minus lens like -7 is riding high on the cornea, using a hyperflange is the appropriate approach. A hyperflange design incorporates a specific edge contour that increases the opposing force at the lens edge, helping to maintain better centration of the lens on the eye. This added feature allows the lens to sit more securely and comfortably, reducing any tendency to slide upwards on the cornea, which can cause discomfort or vision issues.

In contrast, reducing the diameter of the lens could potentially result in a lens that doesn't adequately cover the cornea, leading to problems with lens stability and fit. Increasing the base curve might not be as effective in maintaining the lens position since it could exacerbate the issue of riding high, especially for a high minus lens where the overall thickness and weight distribution need careful balancing. Switching to a softer lens might alter the fit, but wouldn’t address the concern of the lens riding high effectively, especially for individuals who require the correct power from a high minus lens.

Thus, employing a hyperflange provides a targeted solution to optimize lens fit and comfort.
