Chances of iris prolapse out of the main and side wounds.Floppy and flaccid iris that billows in the fluid currents during the cataract surgery.Multiple other drugs can also cause a similar problem. IFIS is usually associated with the use of oral Tamsulosin ( alpha-1A antagonist), a drug used for benign prostatic hypertrophy. The iris loses tone and is flaccid in IFIS. Intraoperative floppy iris syndrome (IFIS) is an important clinical entity which was described in 2005 by Chang and Campbell, This may cause poor pupillary dilation. Increased postoperative inflammation, corneal edema, and cystoid macular edema.Inadvertent placement of one haptic of intraocular lens (IOL) in the capsular bag and the other in sulcus which predisposes to iris chafing, inflammation after surgery, and concentration of the IOL after capsular healing.Retained cortical matter in the peripheral capsular bag which may swell up in immediate postoperative period and may need resurgery for removal.Intraoperative further reduction in pupillary dilation likely related to prostaglandins release or iris touch with instruments,.This.may increase the risk of complications including iris trauma (including chafing, sphincter tear, iridodialysis), hyphema, PCR Less visibility of the peripheral lens and the placement of the tip of certain instruments.An anterior capsular tear may extend beyond the equator causing a posterior capsular rent (PCR). There is a higher chance of trauma to the anterior capsular rim/capsulorrhexis edge with instruments.This causes difficulty in maneuvering the lens during surgery (reduced surgical access) and.Reduced surgical space that may lead to small capsulorrhexis.Nondilating or poorly-dilating pupils pose significant challenges during and after cataract surgeries. 8.12 Canabrava ring (AJL Ophthalmic S.A, Araba, Spain).8.11 Oasis Iris Expander (Oasis Medical Inc.8.10 Xpand NT iris speculum-X1 (Diamatrix Ltd, Woodlands, Texas, USA).8.9 I-Ring pupil expander (Beaver-Visitec International, Waltham, MA, USA).8.8 Assia pupil expander (APX Ophthalmology, Haifa, Israel).8.7 B-HEX Pupil Expander (Med Invent Devices, Kolkata, India).8.6 Milvella Perfect Pupil (Becton-Dickinson, Franklin Lakes, New Jersey, USA/Milvella, Savage, Minnesota, USA).8.5 Malyugin ring (MicroSurgical Technology/MST Inc., Redmond, Washington, USA).8.4 Morcher Pupil dilator Type 5S (FCI Ophthalmics, Pembroke, Massachusetts, USA).8.3 Graether 2000 pupil expander system (Eagle vision, Memphis, Tennessee, USA/Katena Products, Inc., Denville, New Jersey, USA).
