Complications of SICS Dr.Haripriya Aravind
Tunnel construction • Approach • Placement • Length • Depth
Placement • Anterior incision Poor self sealing effect • Wound leak • Astigmatism Management: Suture
Posterior incision • Wide tunnel • Risk of bleeding • Risk of premature entry Difficulty in nucleus delivery and instrument manipulation Management: Suture for premature entry
Incision length • Short incision Difficulty in nucleus delivery Endothelial damage ris damage Management: Enlarge incision with keratome
Long incision Poor approximation • Wound leak • Induced ATR astigmatism Management: Suture
Incision Depth • Premature entry • Button holing • Scleral disinsertion
Descemet’s Stripping • Main wound Instruments • Paracentesis VES/Fluids • Treatment • Air • Viscoelastics
Paracentesis • Site • Size Too central Too peripheral Too small Too big
Capsulotomy CAPSULORHEXIS • Peripheral extension/ Run away rhexis Post capsule tear Management • Reform AC with VES • Pull flap centrally • Cut capsule just ahead of peripherally extending rhexis • Continue in reverse direction • Canopener
Inappropriate size • Too small Management: Enlarge the rhexis by 2 or 3 relaxing incisions • Too big
Hydrodissection • Incomplete hydro • Forceful hydro • PPC Complications • Inadequate cortical-capsular bag separation • Fluid misdirection syndrome • Zonular damage • Posterior capsular tear • Nucleus drop • Capsular block syndrome
Nucleus prolapse Difficult situations • Incomplete hydroprocedure • Small rhexis • Mid-iris synechiae • Very soft nucleus • Hard brown wodden nucleus • Small pupil
Complications • Endothelial Damage • Iridodialysis/Damage to Iris • Zonular Dialysis • PCR
Nucleus Delivery • Endothelial damage • Zonular dialysis/PCR • Iris Sandwich
Iris injury • Sphincter tear • Iridodialysis <1 hr : no intervention >1 hr : suture • Iris prolapse Careful repositioning Suture tunnel Post op steroids & NSAIDs
Iridodialysis McCannel Suture
Hyphema • From tunnel • Posterior tunnel • Deep tunnel • From Iris • Iris handling • Iridodialysis
Intraoperative Miosis • Avoid iris touch • VES • Pharmacological • Spincterotomy • Hook
Zonular dialysis Can be pre/intra operative • Approach • Bimanual prolapse of nucleus • Phacosandwich • IOL 1quad – sulcus (perpendicular to the dialysis) 2quad - CTR >2quad - ACIOL/aphakia
Posterior capsular tear • Seal the tear using visco (don’t hydrate) • Automated ant vitrectomy • Residual cortex - dry aspiration Post op inflammation Obstruct visual axis Secondary glaucoma
Bimanual automated vitrectomy At the start of vitrectimy Completed vitrectomy
Dropped nucleus • If anterior : inject visco : deliver with vectis • Deep into the vitreous : Retinal surgeon intervention
Expulsive Haemorrhage • Tissue prolapse • Hard globe • Loss of red glow • Choroidal haemorrhage • CRAO Rx : Suture IV Mannitol Post segment assessed
Immediate post op complications Wound Dehiscence Etilology • Excessive episcleral cautrey • Premature entry • Button holing • Nuclear or cortical fragment in tunnel • Postoperative IOP rise • Collagen vascular diseases • Leaking paracentesis wound
Treatment • Patch the eye • Cycloplegics • Exploration of wound and suturing
Corneal complications • Corneal edema • Striate keratopathy • Bullous keratopathy
Corneal complications Management : Control inflammation Antiglaucoma drugs Treat epithelial defect Cycloplegics
Post op Iritis • Excess manipulation during nucleus prolapse & delivery • Residual cortex Management • Topical steroids & antibiotics • Cycloplegics • Topical NSAIDs
Post op increase in IOP • Retained viscoelastics • Over distention of AC while reforming Rx: antiglaucoma medications
Late complications • Corneal complications • Uveitis • Capsular bag complications • PCO • IOL malformations • CME • Endophthalmitis
Post segment complications • RD • Lost lens syndrome • Vitreous hemorrhage • Vitritis
Successful management • Recognition • Knowledge • Skill • Judgement
