Opportunity for presbyopia
Presbyopia is a vision disorder caused by the natural ageing of the transparent lens located in the eye. The function of this natural lens is to change its shape to adjust the image sharpness for near vision (accommodation). As we get older, the lens loses its elasticity. It becomes increasingly difficult to clearly see objects up close.
If you need a solution to correct your presbyopia, your eye doctor could suggest you wear glasses or have laser treatment. If also suffer from cataract, you could be eligible for a replacement of your natural with an intraocular lens; however only the trifocal technology could be an option to allow you to reduce your need of glasses.
Your ophthalmologist will advise whether this technology is suitable for your condition.
The trifocal intraocular lens has three different focal points offering a full extended range of vision.
This technology is designed to provide good vision at all distances: near vision (40 cm), intermediate vision (60-80 cm) and far vision. This intermediate distance is increasingly used for instance, for working on a computer, tablet, or smartphone.
The trifocal intraocular lens is a solution for cataract patients with or without presbyopia who want to reduce the burden of their glasses. It can also correct astigmatism, myopia, or hyperopia in a single procedure, which eliminates the need to wear glasses.

The choice of the intraocular lens must consider the existence of associated ocular or general pathologies. The presence of glaucoma, diabetic retinopathy, retinal degeneration is likely to restrict the range of options for choosing an intraocular lens.
Astigmatism is an optical defect likely to be corrected in cataract surgery. It is necessary to correct the astigmatism induced by the cornea, because a possible astigmatism of crystalline origin disappears with the withdrawal of the crystalline lens during the intervention. Implants that correct astigmatism are called "toric IOLs".
Outcomes are the same as trifocal IOLs, including regular astigmatism correction.
The choice of the intraocular lens must consider the existence of associated ocular or general pathologies. The presence of glaucoma, diabetic retinopathy, retinal degeneration is likely to restrict the range of options for choosing an intraocular lens.
