Which of the following is NOT an advantage of a high modulus silicone hydrogel soft contact lens?

• A. Better handling
• B. Edge fluting
• C. Easier application and removal
• D. Easier ability to determine whether the contact lens is inside out

Answer: (B)

Stiffness of the lens material is the key idea here. A high modulus silicone hydrogel lens is more rigid, so it tends to hold its shape better on the finger and on insertion, making handling easier. That rigidity also helps during placement and removal, since the lens is less likely to collapse or stick to itself, giving a more predictable manipulation. The defined edge and preserved form make it easier to tell whether the lens is oriented correctly or inside out, because the edge and overall contour are more noticeable when the lens sits on the eye or on the finger.

Edge fluting, on the other hand, is not a benefit. It’s an irregular or waviness at the lens edge that can be associated with edge design or with a less stable edge contour, and it would be undesirable. A higher modulus lens is not expected to provide this advantage, and in practice, the stiffer edge tends to reduce such irregularities rather than create them.
