risk of pupillary block glaucoma. An opening through the iris can be fashioned manually (surgical iridectomy) or with a laser (called Nd:YAG laser iridotomy). The laser peripheral iridotomy may be performed either prior to or following cataract surgery. The iridectomy hole is larger when done manually than when performed with a laser. When the manual surgical procedure is performed, some negative side-effects may occur, such as that the opening of the iris can be seen by others (aesthetics), and the light can fall into the eye through the new hole, creating some visual disturbances. In the case of visual disturbances, the eye and brain often learn to compensate and ignore the disturbances over a couple of months. Sometimes the peripheral iris opening can heal, which means that the hole ceases to exist. Complications Complications can develop during and after surgery. During surgery Posterior capsular rupture is the most common complication during cataract surgery, with a rate of around 0.5% to 5.2%. This is a tear in the posterior capsule of the natural lens. Surgical management may involve anterior vitrectomy and, occasionally, alternative planning for implanting the intraocular lens, either in the ciliary sulcus, (the space between the iris and the ciliary body), in the anterior chamber (in front of the iris), or, less commonly, sutured to the sclera. Posterior capsule rupture can cause lens fragments to be retained, corneal edema, and cystoid macular edema. it is also associated with a six-times increase of risk of endophthalmitis and as much as 19 times increase in the risk of retinal detachment. Management methods include the Intraocular lens scaffold procedure. Suprachoroidal hemorrhage is a rare complication of intraocular surgery where the ciliary arteries bleed into the space between the choroid and the sclera. It is a potentially vision threatening pathology. Risk factors for suprachoroidal hemorrhage include anterior chamber intraocular lens (ACIOL), axial myopia, advanced age, atherosclerosis, glaucoma, systolic hypertension, tachycardia, uveitis, and previous ocular surgery. Immediate and effective management of a suprachoroidal hemorrhage is necessary to protect vision. Intraoperative floppy iris syndrome has an incidence of around 0.5% to 2.0%. Iris or ciliary body injury has an incidence of about 0.6%-1.2% Posterior dislocation of nuclear fragments: In the event of a posterior capsule rupture, fragments of the nucleus can find there way through the tear into the vitreous chamber. It is not always desirable to attempt to recover the fragments and it is
