When placing an order for a soft contact lens, which of the following is necessary to specify?

Only the lens power
Lens brand or type, case curve, overall diameter, and lens power
Only the overall diameter and lens power
The prescription for glasses instead

The correct answer is: Lens brand or type, case curve, overall diameter, and lens power

The correct choice includes the lens brand or type, case curve, overall diameter, and lens power because these parameters are essential for ensuring that the contact lens fits the patient's eye correctly and meets their vision correction needs. Specifying the lens brand or type is crucial because different brands may have unique materials and designs that influence comfort, vision quality, and wearability. The base curve is important as it dictates how the lens will sit on the cornea, affecting both comfort and lens stability on the eye. The overall diameter ensures that the lens adequately covers the cornea while not being too large or too small, which could lead to complications in fitting or discomfort. Finally, lens power is necessary to correct the patient’s specific refractive error. In order to provide a comprehensive and accurate order for soft contact lenses, all these details must be clearly stated to ensure that the patient receives lenses that are both effective and comfortable.
