Minimal water-jet hydrodissection.

Area of Science:

• Ophthalmology
• Surgical Techniques
• Biomedical Engineering

Background:

• Posterior capsule rupture (PCR) is a significant complication in phacoemulsification cataract surgery.
• Traditional hydrodissection techniques may increase intraocular pressure and risk PCR.
• Effective lens separation is crucial for efficient cataract removal.

Purpose of the Study:

• To evaluate the efficacy and safety of a novel high-speed, low-volume hydrodissection technique.
• To assess the reduction in posterior capsule rupture complications using this method.
• To determine the impact on phacoemulsification and irrigation/aspiration phases.

Main Methods:

• Hydrodissection performed with high-speed pulse injection of 0.1 cc liquid.
• Assessment of technique efficacy, safety, and PCR complication rates.
• Analysis of lens material rotation and facilitation of subsequent surgical steps.

Main Results:

• High-speed pulse injection of minimal fluid (0.1 cc) generates significant kinetic energy for effective dissection.
• Reduced intraocular pressure and anterior capsular block risk compared to conventional methods.
• Facilitated lens rotation improved phacoemulsification and irrigation/aspiration efficiency, thereby reducing PCR.

Conclusions:

• The novel hydrodissection technique is effective and safe for cataract surgery.
• This method significantly reduces the incidence of posterior capsule rupture complications.
• Improved surgical efficiency and safety are achieved through optimized lens separation.
