Intraocular Lenses

The intraocular lens used in the phagocytosis procedure is a small, artificial (acrylic) lens that is surgically implanted and replaces the existing blurred lens. Traditionally, the lens used for cataract surgery was a monofocal lens. The evolution of technology has led to the creation of many new types of intraoculars, so proper choice by the treating physician is important for postoperative vision of the patient.

Modern technology now offers a wide range of choices:

• Monofocal intraocular lens : a focal point (qualitative distant vision). They have the same refractive power across their surface and therefore do not offer the ability to focus on different distances
• Monofocal toric intraocular lens : a focal point for qualitative distant vision and corneal astigmatism. They are also monofocal lenses, configured to serve distant vision, and are aimed at patients who, besides myopia or hyperopia, also have significant astigmatism. Toric lenses have a different force on some axes, in order to neutralize the patient's existing astigmatism. This results in accurate placement of the intraocular torus within the parachute because even a small degree of deviation can lead to blurred vision.
• Multifocal intraocular lens : multiple focal points for near, distant and intermediate vision (treating proximity, intermediate, distant vision). The body of multifocal lenses is divided into annular bands (as a target) with different focusing force to accommodate the patient at different distances.
