What needs to be considered when fitting lenses that are steeper than expected?

When fitting lenses that are steeper than expected, fluctuations in vision become a critical consideration because a steeper lens may not align with the corneal shape effectively. This can cause light to refract improperly onto the retina, leading to inconsistent vision. Such fluctuations can stem from altered lens positioning, as a steeper lens may sit more snugly on the cornea, affecting the way light enters the eye.

In this situation, practitioners need to monitor how the lens behaves on the eye during dynamic activities. If the lens does not settle well on the cornea or creates excessive pressure, it can distort vision by not providing a stable optical zone, leading to visual disturbances. Therefore, assessing and managing potential vision fluctuations is essential to ensure successful lens fitting and optimal patient comfort and sight quality.

Consideration of lens movement, increased comfort, and lens stability are also relevant factors when fitting contact lenses; however, they may not directly address the key issue of vision consistency that arises with steeper lenses. Ensuring the patient has a stable and clear visual experience is the primary goal in these scenarios.
