Intraocular lenses in cataracts are mainly divided into the following categories: 1. Hard intraocular lenses cause a certain amount of astigmatism after surgery
The reaction will be greater in the short term after surgery, and the recovery time will be longer longer. Because the surgical incision is large, some patients need to suture the incision. Currently, fewer people choose 2. Foldable intraocular lens. At present, most (more than 95%) patients will choose this type of intraocular lens, because this type of intraocular lens is usually No sutures are required, the astigmatism is smaller, and the recovery time is faster.
3. Specially treated intraocular lens. For some patients with specific eye diseases, this type of intraocular lens may be needed, such as heparin surface-treated intraocular lens. This kind of intraocular lens will be used after surgery. The inflammatory reaction is much smaller.
4. Multifocal/adjustable intraocular lens This type of intraocular lens is designed to meet the requirements of both distance and near vision at the same time, which is not possible with the above-mentioned intraocular lenses. Multifocal intraocular lenses are made with multiple focal points on one intraocular lens to meet the requirements of seeing at different distances.??
