The Ophthalmology Chang Hydrodissection Cannula 27G is a specialized ophthalmic microsurgical instrument engineered to perform precise hydrodissection during modern cataract surgery. Featuring a 27-gauge cannula, this instrument allows ophthalmic surgeons to inject balanced salt solution (BSS) accurately between the lens capsule and cortical material, facilitating safe separation of the lens nucleus from the capsular bag. Its precision design contributes to smoother nucleus rotation and more efficient phacoemulsification procedures.

Hydrodissection is one of the most critical steps in phacoemulsification cataract surgery, as it creates a fluid wave that gently separates the lens cortex from the capsule without causing unnecessary stress to the zonular fibers or posterior capsule. The Chang Hydrodissection Cannula 27G is specifically designed to provide controlled fluid injection, allowing surgeons to achieve effective hydrodissection with minimal pressure and excellent surgical precision.

The 27G diameter offers an ideal balance between controlled fluid flow and minimally invasive access through small corneal incisions. Its precision-engineered tip enables targeted delivery of balanced salt solution beneath the anterior capsule, promoting complete nucleus mobilization while reducing the risk of capsular trauma. The smooth atraumatic tip is carefully polished to protect delicate ocular tissues, including the corneal endothelium, iris, and lens capsule.

Manufactured from premium medical-grade stainless steel, the Ophthalmology Chang Hydrodissection Cannula 27G provides exceptional corrosion resistance, strength, and long-term durability. The instrument maintains its structural integrity through repeated cleaning and steam autoclave sterilization cycles, making it a dependable reusable solution for hospitals, ophthalmology clinics, and ambulatory surgery centers.

Its lightweight, ergonomically balanced construction provides excellent tactile feedback and allows surgeons to perform precise fluid injection with confidence. The secure hub is compatible with standard ophthalmic syringes, enabling seamless integration into routine cataract surgical workflows. The satin finish minimizes glare under operating microscopes, improving visualization during delicate microsurgical procedures.

The Ophthalmology Chang Hydrodissection Cannula 27G is widely used by ophthalmologists, cataract surgeons, and anterior segment specialists performing cataract extraction and intraocular lens implantation. Every instrument is manufactured under strict quality control standards to ensure dimensional accuracy, smooth finishing, and reliable clinical performance.

Whether used during routine cataract surgery or advanced phacoemulsification procedures, the Chang Hydrodissection Cannula 27G delivers the precision, safety, and durability required by modern ophthalmic surgeons. Its premium stainless steel construction and reusable design make it an essential component of professional cataract surgery instrument sets.
