The Ophthalmology Chang Hydrodissection Cannula 27G is a premium ophthalmic microsurgical instrument specifically developed to perform controlled hydrodissection during phacoemulsification cataract surgery. Designed with a precision 27-gauge cannula, it allows surgeons to inject balanced salt solution (BSS) beneath the anterior capsule, creating an effective fluid wave that separates the cortical material from the lens capsule. This critical surgical step facilitates smooth lens nucleus rotation, safer phacoemulsification, and improved surgical efficiency.
Hydrodissection is one of the most important stages of cataract surgery because it ensures complete mobilization of the lens nucleus before emulsification. The Chang Hydrodissection Cannula 27G provides controlled fluid delivery with exceptional precision, allowing surgeons to perform hydrodissection while minimizing stress on the zonular fibers and posterior capsule. Its optimized design helps reduce the risk of capsular complications and contributes to better postoperative outcomes.
The 27G gauge is ideal for modern micro-incision cataract surgery, providing precise fluid control through small corneal incisions. The finely crafted hydrodissection tip directs balanced salt solution exactly where it is needed, promoting uniform cortical separation without excessive pressure inside the capsular bag. This controlled approach helps preserve delicate ocular structures including the corneal endothelium, iris, anterior capsule, and posterior capsule.
Manufactured from premium medical-grade stainless steel, the Ophthalmology Chang Hydrodissection Cannula 27G offers exceptional durability, corrosion resistance, and long-term clinical reliability. The smooth polished tip is designed for atraumatic tissue interaction, while the high-quality stainless steel construction withstands repeated cleaning and steam autoclave sterilization without compromising precision.
Its lightweight and ergonomically balanced construction provides excellent tactile feedback, enabling surgeons to perform delicate fluid injections with superior control. The standard Luer-lock compatible hub securely attaches to ophthalmic syringes, ensuring accurate delivery of balanced salt solution throughout the procedure. The satin finish minimizes glare under surgical microscopes, enhancing visualization during microsurgical operations.
The Chang Hydrodissection Cannula 27G is widely used in hospitals, ambulatory surgery centers, and ophthalmology clinics by cataract surgeons and anterior segment specialists. Each instrument is manufactured under strict quality standards to ensure dimensional accuracy, consistent fluid flow, and dependable surgical performance.
Whether performing routine cataract extraction or advanced phacoemulsification procedures, the Ophthalmology Chang Hydrodissection Cannula 27G provides the precision, safety, and reliability required by today’s ophthalmic professionals. Its reusable design and premium construction make it an essential instrument for every cataract surgery set.
