If a soft contact lens shows edge lift, what adjustment should be made?

When a soft contact lens exhibits edge lift, it indicates that the lens is not properly conforming to the shape of the cornea at the edges, which can lead to discomfort and reduced stability of the lens on the eye. Steeping the base curve serves to tighten the fit of the lens. By selecting a steeper base curve, the lens will create a closer alignment with the cornea, reducing the likelihood of edge lift occurring.

This adjustment helps to enhance the lens’ stability on the eye, improving both comfort and visual acuity for the wearer. It ensures better coverage of the cornea and can reduce the risk of debris getting underneath the lens, which is important for maintaining both ocular health and eye comfort.

The other options may not address the issue effectively. Increasing the base curve size would potentially worsen the fit and contribute to more lift. Decreasing the diameter could also compromise the lens's stability further. Switching brands may not directly address the underlying issue of fit, as even a different brand can have similar fitting parameters. Thus, steepening the base curve is the most effective solution to manage edge lift in soft contact lenses.
