Toric Lens Implantation:
Toric IOLs are a specific type of intraocular lens used in cataract surgery to correct astigmatism. Astigmatism is a common refractive error where the cornea has an irregular shape, causing blurred vision. Toric IOLs have different powers in different meridians, meaning they have different focusing powers in different directions. This helps to compensate for the irregular shape of the cornea, thereby reducing or eliminating astigmatism and providing clearer vision without the need for glasses or contact lenses after surgery.
Multifocal Lens Implantation:
Multifocal IOLs are designed to provide vision at multiple distances (near, intermediate, and far) simultaneously. They have different zones on the lens surface, each with a different focusing power, allowing the patient to see objects clearly at various distances. With multifocal IOLs, many people can reduce or eliminate their dependence on glasses for tasks like reading, using a computer, and seeing objects at a distance.
Multifocal Toric Lens Implantation:
Combining the benefits of both multifocal and toric IOLs, multifocal toric IOLs are designed to correct both astigmatism and presbyopia (difficulty focusing on nearby objects due to age-related changes in the eye’s lens). These lenses provide a more comprehensive solution for patients with both astigmatism and age-related near vision problems.
