Microkeratome (Keratotome) in Veterinary Medicine
The microkeratome (keratotome) is a mechanical or electromechanical instrument consisting of a very sharp steel or diamond blade capable of cutting a thin and uniform layer of the cornea. While commonly used in corneal and LASIK surgeries to create a corneal flap in human medicine, in veterinary medicine it is primarily used for:
- Corneal biopsies
- Treatment of deep corneal wounds
- Removal of opaque corneal tissue
The device operates by moving the blade across the corneal surface with micron-level precision, producing a smooth, uniform, and controlled incision without damaging the deeper layers of the eye.
Applications in Veterinary Medicine:
- Removal of scarred or opaque corneal tissue in animals with chronic corneal ulcers or infections.
- Corneal biopsy for pathological or microscopic analysis.
- Flap creation in reconstructive or experimental ocular surgeries in veterinary research.
- Superficial keratectomy to smooth the corneal surface when irregularities or calcium deposits are present.
Types of Microkeratome:
- Manual Microkeratome
- Blade movement is mechanically guided by the surgeon.
- Simple and suitable for general veterinary clinics.
- Automated (Motorized) Microkeratome
- Equipped with a small motor and precise depth control.
- Designed for specialized ocular surgeries in animals.
- Disposable and Reusable Blades
- Selection depends on the type of surgery and species of the animal.
Advantages in Veterinary Use:
- Extremely high precision in depth and direction of the incision.
- Minimal damage to surrounding ocular tissues.
- Reduces the risk of postoperative inflammation or infection.
- Suitable for delicate surgical procedures, whether therapeutic or research-oriented.
