Implants multifocaux, toriques et asphériques pour les patients glaucomateux

Cataract surgery has greatly developed over recent years, mainly due to the introduction and availability of newer intraocular lenses (IOLs) with modern platforms and better visual outcomes. Aspheric, multifocal, and toric lenses are among these new lenses. Glaucomatous eyes have a number of particularities that can influence the way these implants are indicated and used. Contrast sensitivity is usually reduced in eyes with glaucoma and, sometimes, a poor IOL choice can aggravate the disease. Small pupils and zonular weakness are frequently associated with certain types of glaucoma (e.g. pseudoexfoliative glaucoma) and can limit the indication of some of the newer IOLs. Lastly, in some cases of combined surgery, the postoperative axial length and anterior chamber depth can change after surgery, requiring adjustments in the IOL power calculation. The purpose of this article is to quickly review some of the specific features of cataract surgery in the glaucomatous eye, some of the IOL choices, and the necessary precautions for these eyes.
