Dense cataract removal and efficient procedure time management

Lens extraction and procedure time

Clinical challenge

Lens fragmentation of a dense cataract requires a lot more phaco energy to emulsify the hard nucleus. More energy increases the risk of damage to corneal endothelial cells, which in turn can cause postoperative complications. Extracting a dense nucleus is also associated with longer procedures, impacting practice efficiency in terms of time and costs.1,2,3

Lens fragmentation of a cataract using ZEISS miLOOP

From gold-standard phacoemulsification to zero-energy lens fragmentation

Clinical solution

With more than 50 years4 of clinical experience, phacoemulsification is seen as the gold standard for lens fragmentation and extraction. Yet, only 25% of cataract surgeons feel confident performing paco chopping.5 Thus, a new technique for full-thickness nuclear fragmentation has been developed that uses a disposable micro-interventional device without ultrasound. This zero-energy approach has been shown to achieve consistent full-thickness nucleus disassembly and significantly improved overall phaco efficiency in dense cataracts.6,7

The application of the right viscoelastic substance to the cornea also helps to protect the corneal endothelium during the emulsification process.8

ZEISS technologies for fragmenting dense cataracts while protecting eye tissues.

ZEISS solution

Using the ZEISS miLOOP for zero-energy lens fragmentation and ZEISS Z-CELCOAT and Z-HYALCOAT for protecting sensitive ocular tissues – reliable support for handling dense cataracts.

ZEISS miLOOP

ZEISS miLOOP

The ZEISS miLOOP allows you to:

  • Reduce phaco energy by up to 53% for grade 3-4+ nuclear cataracts6
  • Lower the surgical irrigation fluid volume used per case by up to 30%6
  • Apply minimal stress to the capsule and zonules6
  • Reduce procedure and post-operative treatment time7
ZEISS OVD Portfolio

ZEISS OVD Portfolio

ZEISS provides two different OVDs to coat the delicate ocular tissues giving you the freedom to choose between a moderate and a comprehensive solution.

ZEISS Z-CELCOAT
Low-viscosity dispersive OVD (HPMC), providing protection of the endothelium through coated ocular tissues.

ZEISS Z-HYALCOAT
Medium-viscosity dispersive OVD, a safeguard during various surgical manoeuvres, providing a great space partition.
