A toric soft lens is effective in correcting which type of astigmatism?

A toric soft lens is specifically designed to correct astigmatism by having different powers in different meridians of the lens. This unique design allows it to effectively address various degrees of astigmatism, making it a versatile choice for both low and moderate levels of the condition.

When considering the types of astigmatism that can be corrected, residual astigmatism refers to that which persists after other types of vision correction, often due to the irregular shape of the cornea. Toric lenses are ideal for correcting this because their customized shape means they can accommodate the specific curvature needed based on the individual's prescription.

Moderate astigmatism, characterized by a refractive error greater than 2.00 diopters, can also be corrected effectively with toric lenses. These lenses can provide the necessary optical power adjustments across the different axes to ensure a clear vision for individuals with this level of astigmatism.

Additionally, toric lenses can correct low astigmatism, which is typically defined as being between 0.75 and 2.00 diopters. For many patients within this range, toric soft lenses can offer significant improvements in visual acuity.
