Posterior Capsular-Zonular Disruption in Planned Extracapsular Surgery

Extracapsular Cataract Extraction With Posterior Chamber Lens Implantation in Patients With Glaucoma

“…17 Savage and coau¬ thors10 also reported a 4.0% incidence in glaucomatous eyes undergoing extracapsular cataract extraction with insertion of a posterior chamber intraocular lens. An incidence of cys¬ toid macular edema as high as 9.9% has been reported by Jaffe18 during his initial series of 91 extracapsular extractions in normal eyes.…”

The incidence of posterior capsule disruption during phacoemulsification and associated postoperative complication rates in dogs: 244 eyes (1995–2002)

“…We did not find that posterior capsule disruption following phacoemulsification in dogs increases the risk of ocular hypertension, severe uveitis, retinal detachment, bacterial endophthalmitis, or IOL decentration. All of these complications, with the exception of uveitis, have been associated with phacoemulsification‐induced posterior capsule disruption in humans 4–12 . However, other studies have found that complication rates were not significantly increased in humans with posterior capsule disruption and some ophthalmologists advocate regularly performing a PCCC to revise inadvertent posterior capsule tears or as a planned primary procedure to prevent posterior capsule opacification following cataract surgery 8,13,14,16 .…”

“…Rupture of the posterior capsule is the most common intraoperative complication associated with routine phacoemulsification in dogs with a reported incidence of 16.5% (49/296) 3 . Complications that have been reported in humans with posterior capsule disruption include vitreous loss, nuclear material falling into the vitreous, an inability to place an in‐the‐bag IOL, IOL decentration, cystoid macular edema, retinal detachment, and bacterial endophthalmitis 4–12 . A planned primary posterior continuous curvilinear capsulorhexis (PCCC) has been used in humans to prevent posterior capsule opacification following cataract surgery in adult patients, to prevent visual axis opacification in pediatric patients, to remove plaques in pediatric cataract extractions, and to manage inadvertent tears of the posterior capsule 8,13,14 .…”

Posterior Capsular Opacification

“…70 Also, equatorial capsule vacuuming has been found to be associated with additional surgery time and trauma and risk of capsule tears, damaging the capsular support of the IOL implant. 71,72 Davidson et al 73 suggested that near 100% removal of residual LECs at the time of cataract surgery may be necessary to prevent LEC proliferation on the posterior capsule and development of PCO. Hydrodissectionenhanced cortical cleanup after cataract surgery to remove retained/regenerative cortical material and cells has been shown to be important for PCO prevention.…”
