 These instruments that you see in my hand, this is referred to as the Kelman, McPherson, IOL forces. First, what is the purpose of this instrument? The function of this instrument is basically to hold the intraocular lens at the haptic-optic junction and to insert it into the capsular bag. A few quick points about this instrument. If you take a look at the prongs of the instrument, they've got very big guards. This is to ensure that we do not inadvertently apply too much pressure because if we do so, we might damage the lens. Now let's come to the features about the tip of this instrument. The tip of the instrument as usual is curved because it has to insert the IOL into the anterior chamber inside the capsular bag. So we hold the intraocular lens at the haptic-optic junction like this and then it is inserted through the limbal incision and once the leading haptic goes in and the lens goes in, then we leave it there and then we use the next instrument which I am going to demonstrate just now to position the lens inside the capsular bag. So this is the Kelman McPherson intraocular lens IOL forces. Stay tuned for another instrument in ophthalmic surgery which is used in cataract surgery.
