Removing hard cataracts can be difficult even for the most experienced cataract surgeons. Patients are typically older, with low visual acuity and coexisting ocular pathologies.1,2
In this case, it is essential to get a detailed understanding of the patient's underlying conditions and prepare for possible challenges during the surgical procedure. Also, informing the patient about their condition is vital to managing expectations.2,3

If you can find a retinal problem before surgery, its a preexisting condition (i.e. the patient owns the problem). If you find the problem after cataract surgery, it‘s considered a complication of the surgery and this puts pressure on us to do pre-operative diagnosis.
A dense cataract is, by its very nature, difficult to penetrate. This makes pre-op cataract evaluation a challenge. Both precise biometric measurement as well as screening for macular pathologies are key to avoid refractive surprises.2,3,4
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 post-operative complications.1,2
After the removal of a dense cataract, patients expect to quickly and permanently regain perfect vision. However, post-operative complications like inflammation and edema can be more common after hard cataract surgery, and, longer term, issues like dislocated IOLs or dysphotopsias may occur.5,6
ZEISS offers reliable technologies and services to optimize cataract procedures - even when a supposedly routine case turns into a challenge. Trust ZEISS solutions for managing dense cataracts to save time and money without compromising your standards or risking an excellent patient outcome.
See how OCT technologies can help manage dense cataracts.
Using the ZEISS IOLMaster 700 with up to 99% cataract penetration rate7 and identifying retinal pathologies with the ZEISS CIRRUS 6000, the performance OCT, for workflow efficiency in the cataract practice.
Explore ZEISS technologies for dissecting the dense nucleus while protecting endothelial cells.
Using the ZEISS miLOOP for zero-energy lens fragmentation and ZEISS Z-CELCOAT* and Z-HYALCOAT* for protecting delicate ocular tissues - reliable support for handling dense cataracts.
