Intended Use

The Nidek Multi Color Laser Photocoagulator Model MC-300 is indicated to be used in ophthalmic surgical procedures, including retinal and macular photocoagulation, iridotomy and trabeculoplasty.

Device Story

Diode pumped solid state laser (DPSSL) system; generates three treatment wavelengths: 532 nm (green), 561 nm (yellow), and 659 nm (red). System splits pumped laser beam into treatment and aiming beams; aiming beam color matches selected treatment wavelength. Laser energy delivered via fiber-optic cable to delivery units, including slit-lamps or binocular indirect ophthalmoscope (Keeler All Pupil II). Used by ophthalmologists in clinical settings for transpupillary photocoagulation. Protective filters in observation path shield operator from reflected laser light. Device enables precise tissue coagulation for ocular pathologies; improves patient outcomes by facilitating targeted retinal/macular treatment and glaucoma procedures.

Clinical Evidence

Bench testing only. No clinical data presented. Device safety and effectiveness established through design verification, product specifications, and risk analysis in accordance with applicable safety standards.

Technological Characteristics

Diode pumped solid state laser (DPSSL); wavelengths 532 nm, 561 nm, 659 nm. Power output 50-2000 mW; pulse width 0.02-3.00 sec; repetition rate 0.2-1.0 sec. Delivery via fiber-optic cable to slit-lamp or binocular indirect ophthalmoscope. Includes protective filters for operator safety.

Indications for Use

Indicated for patients requiring ophthalmic surgical procedures, specifically retinal and macular photocoagulation, iridotomy, and trabeculoplasty.

Regulatory Classification

Identification

(1) A carbon dioxide laser for use in general surgery and in dermatology is a laser device intended to cut, destroy, or remove tissue by light energy emitted by carbon dioxide.(2) An argon laser for use in dermatology is a laser device intended to destroy or coagulate tissue by light energy emitted by argon.

The Nidek Multi Color Laser Photocoagulator Model MC-300 is of comparable type and is substantially equivalent to the following predicate devices: {1}------------------------------------------------ K042785 p. 2 of 4 | Predicate Device | Manufacturer | 510(k) No. | Date Cleared | |---------------------------------------------------------------|-------------------------|------------|--------------------| | Nidek Laser Photocoagulator<br>Model GYC-1000 | Nidek Co. Ltd.<br>Japan | K032085 | October 3,<br>2003 | | Lumenis Novus Varia<br>Ophthalmic Laser &<br>Delivery Devices | Lumenis, Inc. | K022181 | October 1,<br>2002 | The fundamental technical characteristics and device specifications of the Nidek Multi Color Laser Photocoagulator Model MC-300 are the same as those of the predicate devices. The Model MC-300 and the predicate devices are all Diode Laser Pumped Solid State Lasers (DPSSL). The Model MC-300 and the predicate device use a variety of delivery systems, including slit lamps, to deliver the laser beam. The Model MC-300 and the predicate devices are indicated for use in surgical treatment of ocular pathology, including retinal photocoagulation, panretinal photocoagulation, intravitreal endophotocoagulation, iridotomy, iridectomy and trabeculoplasty. #### 4. DEVICE DESCRIPTION The Nidek Multi Color Laser Photocoagulator Model MC-300 is a diode pumped solid state laser (DPSSL) ophthalmic photocoagulation system that produces three treatment beams: a 532 nm (green) wavelength, a 561 (yellow) wavelength, and a 659 (red) wavelength. The Model MC-300 uses the same wavelength for the aiming beam as the treatment beams, so that the operator can recognize the selected wavelength by the color of the aiming spot. The Model MC-300 splits the pumped laser beam into the aiming and treatment beams so that they can both be controlled separately. The multi-color laser beam is aligned with the respective aiming laser beam in the optical system inside the unit and gathers them in a fiber optic cable. The laser beam is led to the delivery unit via the fiber-optic cable, shaped into the specified spot size in the {2}------------------------------------------------ K042785 p. 3 of 4 optical system, and emitted to the affected area (the emission areas of both the therapeutic laser beam and the aiming beam are the same). The Model MC-300 can be used to coagulate the target tissue efficiently and safely, and the system can be applied to transpupillary photocoagulation procedures using a slit-lamp. A protective filter may be attached to each delivery unit in the observation optical path so that the operator's eye can be protected from the laser beam if it is reflected from a patient's eye or contact lens during laser emission. The Model MC-300 uses the following delivery units for use in a variety of ophthalmic procedures: - NIDEK Slit-Lamp Delivery Unit . - ZEISS Slit-Lamp Attachable Delivery Unit . - Binocular Indirect Ophthalmoscope Delivery Unit (Keeler All Pupil II Type) . #### INTENDED USE ડાં The Nidek Multi Color Laser Photocoagulator Model MC-300 is indicated to be used in ophthalmic surgical procedures, including retinal and macular photocoagulation, iridotomy and trabeculoplasty #### 6. TECHNOLOGICAL CHARACTERISTICS A comparison of the technological characteristics of the Nidek Multi Color Laser Photocoagulator Model MC-300 and the predicate devices has been performed, and the results of this comparison demonstrate that the Nidek Multi Color Laser Photocoagulator Model MC-300 has the same basic technological characteristics as the predicate devices and is equivalent to the marketed predicate devices. The 09/30/04 {3}------------------------------------------------ 04 differences between the Nidek Multi Color Laser Photocoagulator Model MC-300 and the predicate devices are insignificant and do not affect the safety or effectiveness of the device. #### PERFORMANCE DATA 7. The Nidek Multi Color Laser Photocoagulator Model MC-300 has been designed and will be tested in accordance with applicable safety standards. System and component testing was completed based on product specifications and hazard effects determined from the risk analysis. #### CONCLUSIONS 8. Nidek Incorporated has demonstrated through its evaluation of the Nidek Multi Color Laser Photocoagulator Model MC-300 that the device is equivalent to the predicate device with respect to intended use, technological characteristics, and safety and effectiveness. {4}------------------------------------------------ Name of Manufacturer: Nidek Co., LTD Laser Model Name and Number: Nidek Multi Color Laser Photocoagulator Model MC-300 Laser Type: (Circle all that apply) Alexandrite, Argon, CO2, Copper-Vapor(Diode) Dye, Nd: YAG, Erbium, Hol: YAG, Krypton, Ruby, KTP/532, Excimer, HENE, Accessory, Other Coumped solid state Indications in this application: Ophthalmic surgical procedures, including retinal and macular photocoagulation, iridotomy and trabeculoplasty FDA Document Control Number: K042785 FDA Product Codes: 79GEX, 86HQF Reviewer Computer Initials: ABC Date of Clearance Letter: 12/3/04 Basis of Approval: (Circle all that apply) Predicate Device (PD) Clinical Data (CD), Animal Data (AD), Specifications (SPECS), Bench Cest Data (BTD), Historical Information (HI), Other __________________________________________________________________________________________________________________________ Description of Laser: The Nidek Multi Color Laser Photocoagulator Model MC-300 is an ophthalmic photocoagulation system that uses a diode pumped solid state laser beam with wavelengths of 532 nm (green), 561 nm (yellow) and 659 nm (red) for therapeutic treatment as well as the aiming beams.
