When symptoms of cataracts begin to appear, you may be able to improve your vision for a while using new glasses, stronger bifocals and greater light when reading. But when these remedies fail to provide enough benefit, it’s time for cataract surgery.
Cataract surgery is very successful in restoring vision. In fact, it is the most frequently performed surgery in Canada. More than 90% of people who have cataract surgery regain very good vision, somewhere between 20/20 and 20/40, and sight-threatening complications are relatively rare.
During surgery, the surgeon will remove your clouded lens and replace it with a clear, plastic intraocular lens (IOL). New IOLs are being developed all the time to make the surgery less complicated for surgeons and the lenses more helpful to patients. Presbyopia-correcting IOLs not only improve your distance vision, but can decrease your reliance on reading glasses as well.
If you need cataracts removed from both eyes, surgery usually will be done on only one eye at a time. An uncomplicated surgical procedure lasts only about 10 minutes. However, you may be in the outpatient facility for 90 minutes or longer because extra time will be needed for preparation and recovery.
