NCLE Practice Exam 2025 – Complete Guide for Test Preparation

Scleral lenses are the most frequently used contact lenses for patients with keratoconus, as they are specifically designed to vault over the irregular shape of the cornea, providing a better fit and improved visual acuity. The design of scleral lenses allows them to create a tear-filled space between the lens and the cornea, which can help reduce corneal distortion and improve comfort for individuals suffering from this condition.

While specially designed cone lenses can be beneficial for certain situations, scleral lenses are generally considered the preferred choice because of their ability to accommodate the unique and progressive changes seen in keratoconus patients. They offer a more stable and effective long-term solution, especially as keratoconus can lead to significant changes in corneal shape. Other types of lenses, such as bandage contact lenses, are typically used for protection or comfort rather than specifically addressing the visual challenges posed by keratoconus. Soft contact lenses usually do not provide the necessary support and correction for the corneal irregularity associated with this condition.
