Premium: LENTIS Tplus (X) intraocular lenses
Patients with severe astigmatism require implantation of toric intraocular lenses. Thanks to their specifically designed optic, the customised and highly precise LENTIS Tplus X IOLs correct any form of regular corneal astigmatism and thus provide the patient with sharp and clear vision.
Premium: LENTIS Tplus (X)
The novel “tailor-made“ Tplus lens generation stands out for its globally unique incision-dependent manufacture of the IOL torus. This manufacturing procedure is tailored to the individual needs of the ophthalmic surgeon and renders any complicated re-alignment of the toric intraocular lens (TIOL) during implantation unnecessary.
When calculating the Tplus X lens simply specify the ophthalmic surgeon’s preferred incision location. Then, the IOL torus will be placed appropriately on the anterior surface of the TIOL (see right figure). This means, LENTIS Tplus X intraocular lenses are produced “customised” – not only for the patient but also for the surgeon.
- Incision-dependent IOL torus production, no re-alignment required
- Individual and highly accurate astigmatism correction to precisely 0.01D
- Very high rotational stability thanks to its haptic design
- Natural high contrast and colour perception
- True 360° sharp optic edge for best-possible PCO prevention
- Aberration neutrality for better depth of focus
- Optional: Violet light filter technology for improved retinal protection

In addition to the central radii of the cornea, the apparatus can complete the topography of the cornea in 3-D. More than 10.000 measuring points (resolution of ± 0.01 D) on the cornea will be included in the calculation, making any irregularity visible. Each deficiency due to cornea irregularity is precisely determined and thus can be treated. Using this quantitative data a tailor-made LENTIS Tplus will be made which guarantees optimal eyesight.
LENTIS: Large selection of IOL designs
The imaging quality of intraocular lenses (IOL) is one of the key factors to ensure an optimal vision for patients after a cataract surgery.
Aspherical LENTIS IOL are characterized by an aberration corrective surface structure. Basis for their design is not as usual a purely spherical cornea but a slightly aspherical cornea (anticipated in the human eye). Studies have shown that the human cornea shows asphericity in respect of the statistical median. Due to this fact, Intraocular lenses, which take into account this aberration, lead to a better visual acuity and better image quality.
Oculentis’ 3-piece aspheric IOL with violet light filter is by its overall diameter of 13.0 mm (optical diameter 6.0 mm) the perfect intraocular lens for the optimal sulcus fixation.
Excursus about Asphericity
Spherical Intraocular Lenses
Spherical aberrations are an optical imaging error, which leads to impaired vision. External light rays are refracted more strongly than the more central rays (see figure). Therefore, not all light rays will focus on the macula (yellow spot or „point of sharpest vision“). This results in poor contrast sensitivity. Spherical intraocular lenses do not correct these aberrations.
Aspherical LENTIS Intraocular Lenses
All aspherical LENTIS intraocular lenses correct these spherical aberrations. The aspherical lens surface focuses all the light rays correctly on the macula. Thereby an optimal image on the retina is created which leads to a very good contrast sensitivity for the patient. In turn twilight vision will be improved.
