Intraocular Lenses Used In CataractSurgery – 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

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! Doesn’t 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 don’t 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 sun’s 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.

3. 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.
