Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The tested IOL model, Liberty 677MTY, has an overall length of 13 mm, an optic diameter of 6.0 mm without haptics angulations but with posterior vaulting. The refractive index of the optic material is 1.46 (at 23°C). The IOL is a single-piece-IOL, the optic and haptics are made from a hydrophilic acrylic co-polymer with integrated - covalently bound UV absorbent. The IOL is produced with yellow filter, covalently bound yellow chromophore. The toric component of Liberty 677MTY IOL is located on the posterior surface of the lens optic. The optic is marked with 2 marks. The marks are positioned exactly in middle between the two loops of haptic at the angulation at the flat axis of toric equivalent. The Liberty 677MTY is available with cylinder powers of 1.0 diopter (D) to 6.0 D. The IOL is designed with sharp edge following 360º to prevent migration of the lens epithelial cells , thereby to prevent PCO formation.
The trifocality of the lens is provided by the EPS technology recently developed by Medicontur uses an elevated phase shift on the central diffractive part of the lens in order to cause constructive interference between the 0th (far) and 1st diffractive (near) order, thus creating a 3rd (intermediate) focal point.
