Clinical Scorecard: Zeiss MICOR 700: Ultrasonic-Free Lens Removal in Cataract Surgery

At a Glance

Key Highlights

• MICOR 700 uses non-ultrasonic, cavitation-free lens removal with a handheld device featuring a three-piston pump and blunt tip design to minimize tissue damage.
• The device reduces fluid usage and thermal energy compared to traditional phacoemulsification, leading to less endothelial stress and clearer corneas postoperatively.
• MICOR 700 offers a smaller operating room footprint, faster setup (approximately 30 seconds), and potential cost savings with disposable tips and no foot pedal.

Guideline-Based Recommendations

Diagnosis

• Standard clinical diagnosis of cataract suitable for surgical removal.

Management

• Use MICOR 700 for lens removal in cataract surgery, particularly in patients with compromised corneas, endothelial dystrophies, softer cataracts, or when rapid visual recovery is desired.
• Continue to use traditional phacoemulsification for dense cataracts or cases where higher efficiency in dense lens removal is required.
• Combine MICOR 700 with adjunctive devices like MiLoop for dense cataracts in compromised corneas.

Monitoring & Follow-up

• Monitor corneal clarity and endothelial cell status postoperatively to assess reduced thermal and fluidic stress benefits.
• Evaluate visual recovery speed and corneal edema compared to traditional phacoemulsification outcomes.

Risks

• Potential reduced efficiency in removing very dense cataracts compared to phacoemulsification.
• Standard surgical risks associated with cataract extraction apply.

Patient & Prescribing Data

Patients undergoing cataract surgery, including those with endothelial compromise and softer cataracts.

MICOR 700 reduces fluid usage (average 18-30 mL vs 50-200 mL with phaco), minimizes thermal damage, and allows faster nucleus removal (~20-30 seconds), contributing to clearer corneas and improved early postoperative vision.

Clinical Best Practices

• Select MICOR 700 for patients with compromised corneas, endothelial dystrophies, softer cataracts, refractive lens exchange, or premium IOL implantation to optimize visual recovery.
• Use traditional phacoemulsification for dense cataracts requiring more efficient lens removal.
• Leverage the handheld design and fingertip vacuum control to maintain fluidic stability and reduce endothelial stress.
• Incorporate MICOR 700 in minimally invasive glaucoma surgery (MIGS) cases to preserve corneal clarity for angle visualization.
• Combine MICOR 700 with MiLoop for enhanced management of dense cataracts in compromised corneas.
