Part 1. Fragmatome Basic Principles
Fragmatome is basically a phacoemulsification handpiece without a sleeve.
It uses ultrasound to emulsify and aspirate lens pieces, fragmatome cannot cut like a vitrector.
Important tips:
- Performe a good core vitrectomy before phacofragmentation
- Elevate an infusion pressure in the eye to more than 30 mmHg
- Be aware of a surge effect
-Work with a fragmatome far from the retina
- At the end of the case evaluate well a vitreous base for retained lens fragments and tears
Part 2. Fragmatome Basic Principles. Step-by-step
Steps of dropped crystalline lens removal by using a fragmatome:
- Step 1: Good core vitrectomy
- Step 2: Fragmatome insertion (removal of the canulla, peritomy +/- diatermy, enlargement of the scleral incision by 19G MVR blade)
- Step 3: Phacofragmentation itself
Important tips:
- Use PFCL to float the lens/lens particles and to protect the posterior pole from the damage
-Emulsify far from the retina
- Prior to closure evaluate the vitreous base for residual fragments and retinal tears
