 Hello, my name is Brian Kimmigan and thank you for having me. I'm going to share with you sulcus lens placement. So when you put the lens in the sulcus, obviously it's a less than ideal situation. And so you want to control as many variables as possible. And I'm not going to go into all those prerequisite steps, but as far as sulcus placement you want to create space in the sulcus with visco elastic and then you want to be able to put that lens into position. So let's go ahead and look at our video. Of course, the sulcus lens should be always be a three-piece lens. Please never ever ever put in a one-piece lens in the sulcus because that will cause problems like UGG syndrome. So this is a patient who had a very small pupil and a dense lens. I put iris hooks in and so now I'm going to fill the sulcus with a cohesive visco elastic and that will create space to be able to put the lens in the sulcus. So you can see me doing that here and you want to use a cohesive visco elastic because it'll be much easier to remove. I use a cannula to hold counter force as I push the lens in and as I dial the lens in you'll see the haptic come out and it comes out like this. You want to make sure it's planar with the sulcus space. So if this is the iris and this is a capsule you want that haptic to be facing the proper direction as you're seeing in the video and as you deliver the optic, oh, here a patient suddenly moved and you know, obviously you want to have exquisite control even when patients move. You want to use an instrument that's shaped like this. This is a maltzmann and you want to be able to get at the crotch of the haptic haptic junction and then push the trailing haptic into the sulcus. Now here it's very important that you place that lens the right way and you want to be able to use something like a maltzmann to push and pull so that you have the lens in proper position. As you can see here, sometimes if you have a tear in the capsular bag or something like that, you want to avoid placing the haptics in the direction of the of the damage and so you want to place the haptics perpendicular to an anterior capsule or a posterior capsule or tear. And of course when you hydrate your incisions be very careful that you don't cause the lens to move. So one, fill the sulcus space with cohesive viscoelastic to use an instrument such as a lester, a kuglen or a maltzmann to be able to push and pull the optic haptic junction to position the IOL into the sulcus. Remember, if you have an anterior post-capsular tear, you want to make sure the haptics are not facing in that direction. You want to make sure they're perpendicular and it's very important to make sure that position is proper. Rotate the lens into position. As I said, you want to close the main incision with a tenon on suture because if this is a complicated case, you don't want vitreous coming forward if the patient rubs their eyes at home. And lastly, don't hesitate to put subconjunctival antibiotics. Thank you for your attention. And again, my name is Brian Kim. I hope this video is helpful to you for your cases and I wish you the best. Good luck.
