To perform micro lamellar keratoplasty for the correction of myopia or hyperopia
Device Story
Plancon Instruments micro lamellar keratoplasty system; used for refractive surgery (myopia/hyperopia correction). System components: gas-powered turbine motor (0-20,000 RPM), adjustable keratome head, stainless steel keratome blade, pneumatic fixation rings, applanation lenses, and vacuum power unit. Operated by ophthalmologists in clinical/surgical settings. Device creates corneal lamellar cuts; surgeon uses applanation lenses and fixation rings to stabilize eye; turbine motor drives keratome blade to perform resection. Output is precise corneal tissue resection; facilitates refractive correction. Benefits include surgical precision in lamellar keratoplasty procedures.
Clinical Evidence
Bench testing only. No clinical data provided.
Technological Characteristics
Materials: stainless steel, titanium, aluminum. Energy source: gas-powered turbine motor (0-20,000 RPM). Components: vacuum pump, pneumatic fixation rings, applanation lenses with engraved reticles. Mechanical operation; no gear system. No software or electronic control systems described.
Indications for Use
Indicated for patients requiring micro lamellar keratoplasty for the correction of myopia or hyperopia.
Regulatory Classification
Identification
A keratome is an AC-powered or battery-powered device intended to shave tissue from sections of the cornea for a lamellar (partial thickness) transplant.
