DALK instruments are specialized tools designed to support precision and safety during DALK surgery (Deep Anterior Lamellar Keratoplasty), a type of corneal transplant replacing the outer, diseased layers of the cornea while preserving the healthy inner layer (Descemet's membrane/endothelium). DALK instruments enable controlled stromal dissection and preservation of Descemet’s membrane throughout the procedure. Key keratoplasty instruments include corneal trephine blades, DALK scissors and dissectors.

| Which instruments are used for the DALK procedure? A DALK set should include a trephine, depth gauge, air-injection cannula, syringes, dissectors, spatulas, scissors, forceps, and suturing instruments. What cannula design is preferred for stromal air injection? A fine, appropriately angled cannula designed for controlled deep stromal air injection is generally selected. Are DALK spatulas available in different curvatures? Yes, spatulas may be straight, curved, angled, or shaped for lamellar dissection. Which trephine sizes are commonly used? Trephine size is selected according to the corneal pathology, recipient dimensions, donor sizing, and surgical plan. They are available in small increments from 7.50 to 9.00 mm. How can instruments help reduce Descemet membrane perforation risk? Appropriately designed blunt dissectors, depth-controlled instruments, fine cannulas, and atraumatic spatulas can support controlled tissue dissection; technique remains critical. Are complete DALK sets available? Complete or customizable DALK sets may be available. |
