Abstract
Objective: To evaluate the safety, benefits and efficacy of initial nucleus sculpting before hydrodisection in different grades of cataract surgery. Subjects and methods: 100 eyes of 68 patients were included in the study with different grades and types of cataract. All underwent coaxial 2.8 mm phacoemulsification using overtly OS3 machine. After capsulotomy an initial groove was made in the nucleus followed by hydrodisection. After hydrodisection 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. Bimanual I/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 hydrodisection facilitated the hydrodisection 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 hydrodisection 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.
