Divide and Conquer With Debulking in Management of Rocky Hard Cataract

June 13, 2026 updated by: Hany Mahmoud,MD, Sohag University

The management of nucleus may be challenging in rocky hard cataracts. Hard cataracts are difficult to fragment, and the excessive energy required to emulsify the hard nucleus can result in complications such as corneal edema, inflammation, wound burn, posterior capsular rupture, and zonular dialysis. different surgical techniques are used for the management of hard cataracts, with their advantages and limitations. Divide and conquer with debulking is a new technique for management of rocky hard cataract.

In this research we assess its safety comparing it with standard divide and conquer technique.
