My name is Gavin Roddy. I'm a glaucoma specialist and cataract surgeon here at Mayo Clinic in Rochester, Minnesota. Today we're gonna be performing cataract surgery on an 80 year old female who's having increasingly difficult time driving. When we remove the lens, we have the opportunity to put an intraocular lens to put the patient's focus wherever they desire, and so we're gonna target clear distance vision without the use of glasses today. Let's get started. OK, so this is a little numbing medication. So we're doing the surgery under topical anesthesia, and this is some intracara lidocaine, and then we fill the eye with viscoelastic. We actually got a little bump in dilation from both the the scholastic and the preservative-free lidocaine mixed with epinephrine. So we're about to perform a hydrous section. This is a bent chain cannula that has a couple of advantages, allows you to get the subincisional hydrous section as well as you can embed into the nucleus and, and rotate the nucleus to confirm a complete hydro dissection. And so the nucleus freely spins. So I prefer the chop technique. And particularly for dense lenses like this, it can help reduce hacal energy. And we use irrigation and aspiration to remove the remaining cortical material. There is an epinuclear bowl because I, I do perform hydro delineation. In order to protect the bag during the chop and fake maneuvers. Sometimes you can flip this eppinuclear ball. And then it'll aspirate quite well. Polish So the cataract is now out and we use a polisher just to polish the posterior capsule. This reduces the risk of developing a condition called posterior capsular pacification. So with the cataract out and the posterior capsule polish, we're gonna inject viscoelastic that's gonna allow us to prepare to insert the new intraocular lens. So we're inserting the intraocular lens, we did select a power to target minimal glasses correction at distance, which is the preference for most patients. Incomplete removal of the scholastic can lead to pressure spikes on postoperative day one, so we want to make sure and thoroughly remove all this scholastic. So we've swept the angloyscholastic. There's no longer any on the corneal endothelium or behind the lens. We hydrate the incisions. To ensure watertight closure without the use of a suture. So the incisions are watertight, and this patient does not have pre-existing glaucoma, so we'll target an intraocular pressure in the low to mid-twenties. We'll now inject an intracameral antibiotic to reduce the risk of postoperative an ophthalmitis. So the incisions are watertight, the pressure is where we want it, and the lens is well centered, so we are all done.
