Intraocular Lenses Used In
Cataract Surgery Arohi Eye Hospital

• Almost 75 of adults around the age of 60 years
  have cataracts in India, with most of them
  undergoing surgery for a better vision and a
  better quality of life. Cataracts is not a low
  vision, but an issue with the lens of the eye,
  which hinders clear vision. The lens of the eye
  starts getting cloudy, which blurs the vision.
  Cataract surgery is one miraculous advancement
  in the field of medical science which has helped
  billions of people get free of such cloudy lens.
  The surgery, with the help of special equipment,
  removes the cloudy lens of the eye, and replaces
  it with an artificial man-made lens. This
  man-made lens is of such precision and quality
  that it is completely safe for the eyes, and
  brings back vision brighter and clearer than
  before!

The lens used in cataract surgery A cataract
forms when the tissue that focuses light onto the
retina becomes cloudy and blocks the changes in
light from the retina, which prevents nerve
signals from telling the brain what it is
seeing. This problem can be easily corrected with
the help of manual cataract surgery. As we said
above, cataract surgery involves replacing the
natural clouded lens of the eye with an

• external man-made lens. This lens is known in
  medical terms as intraocular lens, or IOL. Just
  like spectacles and contact lenses, these IOLs
  also come in a variety of focusing powers. It is
  very important that the right power of IOL is
  inserted into the eyes for improved vision. If
  not, the surgery would be of no use. This is why
  it is important that you have your eyes
  thoroughly checked by a specialist so that the
  right kind of IOL can be identified for your
  eyes.
• How is the lens inserted into the eyes?
• Imagine the lens of your eye being cut and
  separated from your eyes, and a new one being
  inserted within! Doesnt it all sound so creepy
  and painful? But, as much as it sounds, cataract
  surgery is actually a very safe and painless
  procedure. First, you will be given local
  anesthesia so that your eyes are numbed, and you
  dont feel any kind of pain. Then, a tiny
  incision is made at the front of your eye, after
  which a small tool is used to break the natural
  lens in the eye, and suction it out. Finally,
  the artificial lens or IOL is put in place.
• Which IOL to choose?
• There are a number of IOLs available for you to
  choose from. They are generally made of acrylic
  or silicon, and are coated for protection from
  the suns ultraviolet rays. Apart from the
  material, the IOLs are also differentiated as
  per the type. Some of the different IOLs
  available include
• Monofocal IOL These lenses help the patient
  focus on one focal point at a time thus helping
  patients treat either only nearsightedness or
  only farsightedness.

• Multifocal IOL These lenses help the patient
  see clearly at both distances near and far, thus
  offering complete freedom from both nearsighted
  and farsighted glasses.
• Monovision IOL These lenses also help the
  patient see clearly at both the distances, but
  the difference here is that both the eyes are
  installed with different lenses one that sees
  near, and the other that sees far. So, you can
  say that even though complete freedom is offered
  from spectacles and contact lenses for both
  nearsightedness and farsightedness, only one eye
  is used at a given time.
• Toric IOL These lenses help patients suffering
  from both cataracts and astigmatism. This proves
  to be a boon for those suffering from
  astigmatism too, but the disadvantage is that it
  can solve only your nearsightedness or
  farsightedness, and not both.
• As you can see how complicated it can be to
  choose one right lens for your eyes, we would
  suggest you to consult an experienced eye
  surgeon for the same. Arohi Eye Hospital is one
  place where you can get the best eye
  consultation as well as the best cataract
  surgery in Mumbai.
