Which of the following factors will not improve lens stability in a soft toric lens?

Utilizing a thicker lens design does not necessarily improve stability in a soft toric lens. In fact, while thickness can impact the weight and movement of the lens on the eye, it is not the most effective method for enhancing stability. Thicker lenses may lead to increased centration issues or discomfort, which can counteract the benefits sought in maximizing lens stability.

Adding a prism ballast helps to stabilize the lens by providing a weighted area that aids in maintaining the desired orientation during blinks or eye movement. This method directly contributes to lens stability, making it an effective choice for soft toric lenses that require consistent alignment for optimal vision correction.

Using a lower modulus material is advantageous for soft lenses since it tends to enhance flexibility and comfort, and can help the lens conform better to the eye's surface. A more compliant lens can adapt to blinking and eye movement, aiding in stability.

Increasing the overall diameter of the lens also typically contributes to stability. A larger lens ensures more coverage of the cornea, which can help maintain its position and reduce the chances of dislocation during eye movement.

Thus, while higher thickness might lead to an impression of a more stable lens, it doesn't effectively enhance stability in the same manner that other factors do, making it the correct
