Cataract surgery can improve vision by removing the cloudy natural lens and replacing it with an artificial lens called an intraocular lens (IOL). While IOLs can provide clear distance vision, they may not correct all vision problems, such as presbyopia or astigmatism. Many people still require glasses or contact lenses after cataract surgery to correct these issues and achieve optimal vision. However, there are options for presbyopia-correcting IOLs that can reduce the need for glasses or contact lenses after surgery. It’s important to discuss with your doctor what options are available for your specific needs.
