Prism‐Ballasted and Truncated Spherical Trial Lenses As Indicators of Toric Soft Lens Rotation

Key Points

• The research aims to evaluate the effectiveness of prism ballasted and truncated spherical lenses in fitting toric soft lenses in astigmatic individuals.
• Fitted fifteen refractive astigmats with prism ballasted and truncated spherical lenses and prescription toric soft lenses.
• Monitored and recorded the initial rotation of each lens type.
• Initial rotation of prism ballasted lenses and truncated spherical lenses did not differ significantly.
• Trial lenses may be used effectively for fitting toric soft lenses.
