Lenticular or residual astigmatism can be corrected by which type of contact lens?

Lenticular or residual astigmatism refers to astigmatism that can remain even after corrective eyewear has been utilized, often due to the shape of the cornea or the lens of the eye. To effectively correct this type of astigmatism, contact lenses need to conform to the irregular shape of the cornea and provide adequate alignment in order to achieve optimal vision clarity.

Soft toric or bitoric contact lenses are specifically designed to correct astigmatism by having different powers in different meridians of the lens. This design helps accommodate the varying curvature of the cornea or the lens, thereby providing a stable and effective solution for patients with lenticular or residual astigmatism. The toric shape ensures that the lens sits properly on the eye and maintains its position during blinking and movement, which is crucial for maintaining clear vision.

In contrast, other lens types, such as monovision soft lenses, rigid astigmatic lenses, and single vision lenses, do not provide the necessary correction for astigmatism in the same way. Monovision lenses are designed primarily to correct for presbyopia and may not adequately address the specific needs of someone with astigmatism. Rigid astigmatic
