Presbyopia Correcting IOLs For Phakic & Pseudophakic Eyes

Cataract surgery patients today are increasingly interested in reducing their dependence on spectacles across a full range of vision.

Presbyopia Correcting IOLs for Phakic & Pseudophakic Eyes

Cataract surgery patients today are increasingly interested in reducing their dependence on spectacles across a full range of vision. Created using optical principles and knowledge of ocular physiology, the Liberty trifocal (677MY / 677MTY) presbyopia correcting trifocal IOL from Medicontur was engineered to meet the functional needs of the modern cataract surgery patient population and optimise quality of vision.

Through EPS we are able to create a third focal point for an intermediate peak with only seven rings within the central 3mm of the optic, leaving 75% of the lens surface as refractive

Contrast Sensitivity & Dysphotopsia

Light scattering contributes to loss of contrast sensitivity and the development of dysphotopsias with MIOLs. Therefore, the potential for a diffractive optic to reduce contrast sensitivity and cause bothersome dysphotopsias is a consideration when contemplating implantation of a MIOL.

“It should not be forgotten, however, that loss of media transparency causes an increase in light scattering. Therefore, decreased contrast sensitivity and symptoms of dysphotopsia are already experienced by patients who have cataract,” Dr Fernández said.

Design Matters

The Liberty IOL is manufactured of a time-tested 25% hydrophilic copolymer material and built on the Bi-Flex platform that incorporates multiple design features for ensuring proper fixation, preventing posterior capsule opacification (PCO), and maintaining positional and refractive stability.

The Bi-Flex design is characterised by a double C-loop haptics that have a large contact angle (2 x 88.8o) with the capsular bag equator that allows for proper positioning but also for flexibility, which confers stability through resistance against compressive forces from capsular bag contraction. (Fig 9). As another key aspect of the Liberty IOL design, its optic has a 360o sharp square edge (≤10 microns) that includes the optic-haptic junction zone for protection against lens epithelial cell migration.

“We designed this platform to excel in rotational and refractive stability, and we are continuing to see great results through clinical experience,” said László Kontur.

Elevated Phase Shift Technology for the Sulcus

Clinical experience with the 1stQ AddOn® IOLs show that these supplementary IOLs, which use the same EPS technology as the Liberty trifocal IOL, are well-designed to provide safe and effective presbyopia correction in patients previously implanted with a monofocal IOL, agree surgeons who have used the technology.
