Clinical challenge

Treating dense cataracts – when routine becomes a challenge

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


William F. Wiley, M.D. USA

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.

Dense cataract workflow challenges

Assess

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

Treat

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

Check

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
