The OPHTHALMIC YAG LASER SYSTEM YC-200 consists of a slit lamp and the YAG Laser and is indicated for the performance of posterior capsulotomy, pupillary membranectomy, iridotomy (hole in the iris) and selective laser trabeculoplasty.

Device Description

The OPHTHALMIC YAG LASER SYSTEM YC-200 is an ophthalmic pulsed laser system using a 1,064 nm Q-switched pulsed Nd: YAG laser as the treatment beam source. The system consists of the types, differing only in the available types of laser emission. The two types are collectively referred to as "YC-200" throughout this 510(k). The operation mode available differs depending on the type.

Type	Model	Emitted Laser (wavelength)	Operation Mode available
YC-200	YC-200	Nd: YAG laser (1,064 nm)	YAG mode
YC-200 SPlus	YC-200	Nd: YAG laser (1,064 nm)SLT laser (532 nm)	YAG modeSLT mode

As shown in the above table, the YC-200 S Plus provides the operator with two treatment modes, YAG mode and SLT mode, whereas the YC-200 type provides the operator with a single treatment mode, YAG mode. Hereafter, these two types are collectively referred to as "YC-200".

In YAG mode, treatment using the YAG treatment beam whose wavelength is 1,064 nm is available. This mode is used mainly for posterior capsulotomy and iridotomy. The 360-degree rotating two-aiming-beam system that separates the YAG aiming beam into two beams is used. The focus position is determined according to the alignment of the beams. In YAG mode, single irradiation mode and burst mode are available. In single mode, one shot of the treatment beam is emitted each time the trigger switch is pressed, whereas in burst mode, two or three shots of the treatment beam are emitted each time the trigger switch is pressed. In YAG mode, the focus shift function to shift the focal points of the YAG treatment beam on the basis of the YAG aiming beam is available. This function allows the operator to shift the focal point of the YAG beam to the posterior chamber side compared to the aiming beam in order to prevent pitting of the intraocular lens.

In SLT mode, treatment using the YAG treatment beam whose wavelength is 532 nm is available. This mode is used for selective laser trabeculoplasty. In this mode, a parfocal optical system is used. In the parfocal optical system, the image of an object surface is formed on the target surface. The SLT aiming beam is emitted from the fiber tip (the object surface) so that it appears as a sharply-edged spot on the target surface. The focus position is determined according to the projection status of the beams. In SLT mode, SLT-NAVI that assists the operator in surgery by specifying the laser emission positions and sequence before the treatment is available. The progress status of laser treatment is intuitively displayed in real time in the SLT-NAVI area of the main screen based on the premise that the treatment is proceeding as scheduled.

The system is mainly comprised of the YC-200 main body that incorporates a laser source, and a slit lamp that is similar to the previously cleared SL-2000 (K163564), head rest, the control box that controls laser emission, and a connector box.

To use the YC-200, the operator should first adjust the focus of the eyepieces to the opera-tor's refractive error and adjusts the eyepieces to the operator's pupillary distance. The operator instructs the patient to place his or her chinrest, to rest his or her forehead on the forehead rest, and to hold the grips. The operator aligns the level of the patient's eye with the eye level marker, fasten the patient's head with the head belt, and instructs the patient to look at the fixation lamp to stabilize his or her visual axis. The operator looks through the microscope to observe the treatment site. The operator sets laser emission conditions such as laser power output through the control box of the YC-200, turns on the aiming beam, and set the YC-200 to the READY mode. Alignment is achieved when the operator adjusts the joystick and contact lens to align the aiming beam focus with the target position. Finally, the operator presses the hand switch or depresses optional foot switch to emit the treatment beam in the READY mode while observing the operative field with the slit lamp.

PREDICATE AND REFERENCE DEVICES

· Quantel Medical OPTIMIS FUSION YAG, and OPTIMIS FUSION YAG/SLT (as the predicate device) (K140336)
Lightmed Corporation LightLas SeLecTor Deux (as a reference laser device)(K090774)
NIDEK Slit Lamp SL-2000 (as a reference device)(K163564)

The OPTIMIS FUSION YAG, and OPTIMIS FUSION YAG/SLT (hereafter referred to as "predicate device") are chosen as the predicate device because the device has the most similar indications for use and technological characteristics to the YC-200.

The LightLas SeLecTor Deux is necessary and appropriate to support substantial equivalence in energy output in YAG mode and SLT mode, pulse repetition rate in YAG mode and SLT mode, and anterior and posterior offset in YAG mode.

The NIDEK SL-2000 is also necessary to support substantial equivalence to the slit lamp that is incorporated into the YC-200.

SUBSTANTIAL EQUIVALENCE

The YC-200 is substantially equivalent to the predicate device, OPTIMIS FUSION YAG, and OPTIMIS FUSION SLT/YAG as the predicate device, LightLas SeLecTor Deux as a reference laser device, and NIDEK Slit Lamp SL-2000 as a reference device. The YC-200, the predicate device, and reference laser device are Nd:YAG photodisruptor laser and Selective Laser Trabeculoplasty (hereafter referred to as "SLT") lasers intended for use in ophthalmic surgical procedures, including posterior capsulotomy, pupillary membranectomy, and selective laser trabeculoplasty in the same anatomical sites. In addition, both the YC-200 and the predicate device are intended to perform iridotomy.

In regards to the slit lamp integrated into the subject device, the previously-cleared SL-2000, chosen as a reference device, is slightly modified in hardware for integration into the subject device. Minor differences between the subject device and reference slit lamp device are the result of changes to the intended use and modification to the reference device to be incorporated into the subject device that is a laser surgical device.

YC-200 510(k) 4 of 5

{7}------------------------------------------------

The YC-200 is similar to the predicate device and reference laser devices in indications for use, principles of operation, technological characteristics, and performance. Any differences in technological characteristics among the subject device, predicate device, and reference devices do not raise any new issues of safety or effectiveness. Thus, the YC-200 is substantially equivalent to the predicate device and reference devices.

TESTING IN SUPPORT OF A SUBSTANTIAL EQUIVALENCE DETERMINATION

All necessary bench testing was conducted on the OPHTHALMIC YAG LASER SYSTEM YC-200 to support a determination of substantial equivalence to the predicate and reference devices. The tests performed include:

Ophthalmic testing per ISO15004-1
Testing for Protection against Light Hazard per Z80.36 and ISO15004-2
· Slit Lamp Testing per ISO 10939
Laser Product Safety Testing per IEC 60601-2-22 and IEC 60825-1
Usability Testing per IEC 62366-1
Electrical Safety Testing per ANSI AAMI ES60601-1 and Electromagnetic Compatibility Testing per IEC60601-1-2.

The collective performance testing demonstrates that the YC-200 is substantially equivalent to the predicate and reference devices. The results of the performance testing demonstrate that the YC-200 performs as intended.

SUMMARY

The OPHTHALMIC YAG LASER SYSTEM YC-200 is substantially equivalent to the predicate and reference devices.
