ADVANTAGES

• Circular expansion of the capsular bag
• Stabilization of the capsular bag
• With small zonular damage, no scleral fixation is necessary
• Reduces the risk of damaging the capsule or zonules during surgery
• Better centering of the IOL, and in cases of future capsular bag shrinkage
• Simplifies the implantation of foldable IOLs
• Allows safe aspiration of lens material
• Helps prevent rotation of Toric IOL

Indications

• Weak or partially absent zonules
• Potentially complicated surgical conditions
• Luxation of IOLs
• Zonulysis
• Pseudoexfoliation
• Primary zonular weakness including Marfan Syndrome
• Secondary zonular weakness including trauma or vitrectomy
• Stabilize the capsule in case of severe myopia

Contraindications

• Zonular damage larger than 4 hours except for Malyugin/Cionni CTR
• Patients with perforated or damaged capsules
• Children 12 years of age or younger
• Chronic uveitis
• Progressive eye diseases (diabetic retinopathy, uncontrolled glaucoma)
• Preoperative complications prior to cataract surgery (vitreous body prolapse, hemorrhage)
