Corneal trephine blades and funnels are precision instruments used in corneal surgery and therapeutic procedures. Corneal blades enable accurate circular incisions while corneal funnels (often referred to as corneal wells) are used to contain and localize solutions such as alcohol (for epithelial debridement) or riboflavin (for corneal collagen cross-linking).

| FAQ |
|---|
| Which trephine diameter should be selected? Trephine diameter is determined by donor/recipient sizing, corneal pathology, and the surgical plan. Common corneal sizes are selected in small increments. Are blades disposable? Trephine blades from RUMEX are reusable following the Care & Cleaning Instructions. Are donor and recipient systems available? Yes, systems for donor and recipient preparation may be available, including matched or intentionally oversized donor options. How is centration maintained? Centration is achieved with appropriate marking, visualization, suction or guide systems where applicable, and careful alignment by the surgeon. What funnel sizes are offered? RUMEX offers funnel size 8.00 mm. Make sure it matches the donor tissue and trephine diameter. |
