After cataract extraction and implantation of a conventional monofocal IOL, theoretically there will be no adjustment and the best vision will be achieved only at a certain distance. Patients with good post-operative distance vision often need to wear “presbyopes” for reading the newspaper. If you do not want to wear glasses after surgery, you can choose multifocal IOLs.
The results of domestic and international studies show that this type of IOL has certain adjustment function in the eye and achieves good distance and near vision, but some patients have difficulty accepting the visual status of this type of IOL after surgery, and some patients still need to wear glasses after surgery because of its limited adjustment power. At present, most patients are still mainly implanted with monofocal IOLs.
