What is intraocular lens surgery?

Intraocular Lens Surgery (IOL), also known as cataract surgery, is a procedure in which a damaged or clouded natural lens of the eye is removed and replaced with an artificial lens.

  • The natural lens, which is located behind the iris and the pupil, can become cloudy over time due to a condition called a cataract, which can cause a decrease in vision.
  • The surgery is typically performed as an outpatient procedure, meaning that the patient goes home the same day.
  • It is done under local anesthesia and typically takes about 20-30 minutes to complete.
  • During the procedure, the surgeon will make a small incision in the cornea and remove the natural lens using ultrasound.
  • The artificial lens (IOL) is then inserted through the same incision and positioned in the same location as the natural lens.
  • There are different types of IOLs, including monofocal and multifocal IOLs.
  • Monofocal IOLs are designed to correct distance vision, while multifocal IOLs are designed to correct both distance and near vision.
  • Some IOLs are also accommodating the light to reduce the glare and halos around lights at night.

Recovery time following cataract surgery can vary, but most people are able to return to normal activities within a few days. It's important to follow the post-surgery instructions provided by the surgeon, including the use of eye drops and avoiding certain activities such as swimming, heavy lifting, and strenuous exercise for a period of time.
