If a soft lens exhibits edge lift when observed on a cornea, how can this be corrected?

When a soft contact lens exhibits edge lift, it indicates that the edges of the lens are not adequately conforming to the curvature of the cornea, resulting in a gap that can lead to discomfort and impaired lens stability. The effective way to correct this issue is by steepening the base curve of the lens.

Steepening the base curve means that the curvature of the lens becomes tighter, which allows it to better conform to the shape of the cornea. This adjustment can help bring the edges of the lens closer to the cornea, reducing the lift at the edge and improving the overall fit and alignment of the lens. A more fitting curve allows for better stability, potentially better vision quality, and greater patient comfort.

The other options, while they concern lens fit and performance, would not effectively address edge lift in this context. Flattening the base curve would exacerbate the lift issue by making the lens less conforming to the cornea. Increasing the lens diameter could potentially help depending on the specific case scenario, but it typically doesn't address edge lift directly, as it would require further assessment to ensure a proper fit overall. Decreasing the lens power does not relate to the curvature of the lens that affects edge lift; it primarily influences the lens’s
