Phacoemulsification: Grooving and Cracking

  • Rajen Gupta


Two key surgical phacoemulsification skills to acquire are the ability to form a trench in the lens nucleus (referred to as grooving or sculpting), and the ability to apply pressure to the walls of the trench, dividing the lens nucleus into two smaller segments (cracking). Lens grooving and lens cracking form the basis for one method of disassembling the lens nucleus.
