Objective: To evaluate the safety, benefits and efficacy of initial nucleus sculpting before hydrodissection in different grades of
Subjects & Methods: 100 eyes of 68 patients were included in the study with different grades and types of cataract. All underwent
coaxial 2.8 mm phaco-emulsification using oertli OS3 machine. After capsulotomy an initial groove was made in the nucleus
followed by hydrodissection. After hydrodissection and nucleus rotation the groove was further deepened and nucleus was
divided by half and then quadrants were emulsified. Pulse mode was used in all stages of emulsification; BimanualI/A of residual
lens cortex and foldable IOL implantation. Postoperative follow up was 6 months after surgery.
Results: All patients achieved UCDVA better than 0.7 one week after surgery, sculpting of the nucleus before hydrodissection
facilitated the hydrodissection and allowed more fluid to be pushed in the capsular bag. Furthermore nucleus rotation was made
easier by the presence of a hinge made by the initial groove. Furthermore it allowed refilling the AC with viscoelastic after the
initial groove adding more protection to the corneal endothelium.
Conclusion: Initial nucleus sculpting before hydrodissection is an effective and safe phaco-technique and it appears to work
good in different grades of cataract. Also it decreases the phaco-time and protects the corneal endothelium.
