Miotic pupil • Poor visualization
• Increased risk for capsule tear/vitreous prolapse
• Increased risk for iris damage and prolapse
Posterior polar cataract • Defective posterior capsule
• Increased risk of dropped nucleus
Posterior synechiae • lntraoporative miosis
• Prolonged postoperative inflammation
• lnflammatory deposits on IOLs
• Iris bleeding
Potential need for
vitreoretinal surgery
• Silicone IOLs may compromise subsequent surgical
visibility if posterior segment surgery or silicone oil is
needed
Prior anti-VEGF
injections
• Endophthalmitis
• Posterior capsular rupture
• Retained lens fragments
Prior glaucoma
filtration surgery
• Increased filtration through the bleb during surgery
• Decreased filtration or bleb failure after surgery
• Postoperative hypotony
• Zonular laxity
Prior keratorefractive
surgery
• IOL-power calculation inaccuracy
• Transient hyperopic shift immediately after surgery in eyes
with a history of radial keratotomy
• Dehiscence of a radial keratotomy incision
• Reduced visual potential due to irregular astigmatism
• Corneal aberrations with glare and haloes
Prior pars plana
vitrectomy
• Conjunctival scarring
• lntraoperative anterior chamber depth fluctuation,
especially severe deepening
• lntraoperative miosis
• Increased nuclear sclerosis
• Increased frequency of posterior capsule plaques
• Weakened lens capsule and zonules
