Dense cataracts

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
