Which of the following statements is true regarding a front toric lens order?

• A. It is ordered for corneal astigmatism equal to or greater than 1.00 diopters
• B. It is ordered if residual astigmatism is less than 1.00 diopters
• C. It is ordered only for patients with no astigmatism
• D. It is ordered if residual astigmatism is more than 1.00 diopters

Answer: (D)

Ordering a front toric lens is particularly relevant in cases where residual astigmatism is present. When there is more than 1.00 diopters of residual astigmatism, a front toric lens can help correct for this remaining astigmatism effectively. This lens design allows for the appropriate adjustment of the optical properties required to compensate for the corneal irregularities that cause astigmatism. In general, front toric lenses are engineered to provide a more enhanced visual acuity for patients who do not achieve satisfactory results with standard spherical lenses. The ability to align with the cornea’s astigmatism allows for an improved visual quality by mitigating blurriness that may arise from astigmatism. The other options inadequately describe the appropriate circumstances for ordering front toric lenses. For instance, ordering toric lenses for corneal astigmatism of 1.00 diopters or less isn't as critical unless there is significant visual impact, and toric lenses are not suitable if there is no astigmatism at all. The choice effectively highlights the necessity for correction at higher levels of residual astigmatism.
