Segmentation by type classifies cannulas into single‑port, dual‑port, and micro‑flush configurations. Single‑port cannulas, the most widely adopted, dominate the market because they offer a simple fluid pathway suitable for routine cataract cases; their cost‑effectiveness supports broad hospital procurement. Dual‑port designs, comprising separate irrigation and aspiration channels, capture a growing share in complex procedures such as phaco‑emulsification with high fluid turnover, delivering enhanced chamber stability at a modest premium. Micro‑flush cannulas, engineered with ultra‑fine lumens and ergonomic tips, serve niche applications including pediatric cataract and minimally invasive glaucoma surgery, where precision and reduced trauma are critical. Although each type represents a distinct portion of the total volume, the aggregate of these configurations underpins the overall market, with single‑port contributing the largest absolute sales, dual‑port driving incremental growth, and micro‑flush sustaining specialized demand. Pricing differentials, regulatory clearances, and adoption curves further delineate the revenue impact of each type, reinforcing their complementary role in market expansion.
