# Accessory Filters

The D.O.R.C. lightsource is available with five different accessory filters. They are ordered at the time of initial purchase for factory installation. These filters are:

- 585 A Green Filter
- 585 B Yellow Filter
- 585 C Red Filter
- 585 D Blue Filter
- 585 E Daylight Filter

# Accessory Filters

The Synergetics lightsource incorporates five different imaging enhancing filters. These filters are installed at the factory. These filters are:

- Filter #1 - White light Filter
- Filter #2 - Triple-band filter
- Filter #3 - UV/Blue light filter
- Filter #4 - Blue narrow band filter
- Filter #5 - Green narrow band filter
- Filter #6 - Red narrow band Filter

The Synergetics #1 filter is equivalent to using the D.O.R.C. lightsource without any of its accessory filters. There is no difference in terms of the safety and effectiveness in regards to the filter #1 as it provides the basic white light output with UV and IR filtering.

The Synergetics #2 triple band filter has no equivalent in the D.O.R.C. lightsource. There are no differences in terms of safety and effectiveness as this filter only serves to block the light output in the areas that are in between that of the primary colors; blue, green and red. This can only reduce the overall power output as compared to the #1 white light filter.

The Synergetics #3 UV/Blue light filter has no equivalent in the D.O.R.C. lightsource. The D.O.R.C. lightsource produces a substantial amount of light below 495nm and does not incorporate this UV/Blue light safety feature.

There is no differences in regards to safety and effectiveness of the Synergetics filters #4,#5 and #6 as they are just color filters that transmit a narrower spectrum in their particular color range than the color filters used in the D.O.R.C. lightsource.

# Visible Light Output

The D.O.R.C. lightsource produces "white 5600°K temperature light. As tested by Tayman Medical the overall power output of the D.O.R.C. lightsource was 17.8mW.

# Visible Light Output

The Synergetics lightsource produces a "white" 5500°K temperature light. The overall power output potential of the Synergetics lightsource is 36.1mW's when using white light filter #1, a large fiber endoilluminator and the high power brightness range. When used in the standard power brightness range with a large fiber endoilluminator or the high power range with a small fiber endoilluminator the power output is approximately 15.0 mW. This power output is approximately the same power output as most existing vitreo-retinal lightsources. When used This filter provides the most light transmission and therefore all of the other filters would result in lower light output.

There are no differences in regards to safety and effectiveness as the extra power present in the lightsource is only used when it is attenuated by the use of small fiber endoilluminators, special image enhancing filters or when the specific surgical situations that requires and permits the use of this higher than standard power output are present. Various statements regarding the safe use of this lightsource in high power mode are provided in the device labeling and owners manual.

# UV Light Output

The D.O.C.R. lightsource produces a substantial amount of light below 420nm.

# UV Light Output

The Synergetics lightsource white light filter #1 blocks the lamps UV output below 420nm.

This filters provides the least UV attenuation and therefore the use of any of the other Synergetics Lightsource filters would result in even lower UV output.

The Synergetics lightsource also incorporates a UV/Blue light filter. This filter blocks the UV-blue light below 495nm and is for use in certain circumstances where it is desirable to have the UV-blue light component reduced even further than that achieved when using the white light filter # 1. This filter does result in a light output that is extremely yellow but there are times when this light quality verses additional safety is justified. Such instances may be when the surgeon will be spending a lot of time with the endoilluminator in close proximity to the retina. For example during membrane peeling procedures using a endoilluminator with integral pick. This UV/Blue light filter also incorporates the standard IR blocking as outlined below.

The UV/Blue light output is considerably less than the D.O.R.C. lightsource. Many studies have been done that show that the extended use of UV light below 420nm in vitreo-retinal illumination can cause phototoxicity damage to the eye. Therefore the illumination of the UV light below 420nm is critical to safe intraocular illumination. And, it is safer than the D.O.R.C. lightsource in this regard..

{5}

# IR Light Output

The unfiltered ILC lamp that the D.O.R.C. lightsource uses is expensive and very inefficient for visible light only applications. Testing by Synergetics and product information supplied by ILC show that the *unfiltered* lamp produces almost 60% of its power output in the harmful I.R. range. This results in a lightsource that could be very dangerous if its internal I.R. filter were to break or is removed for some reason.

# IR Light Output

The Synergetics lightsource white light filter #1 blocks the lamps IR output above 700nm.

This filter provides the least IR attenuation and therefore the use of any of the other filters would result in even less IR output.

There is no difference in terms of the safety and effectiveness in regards to the IR output of the Synergetics lightsource as many studies have been done that show that the extended use of heat producing IR light above 700nm in vitro-retinal illumination to be potentially dangerous to the eye. Therefore the Synergetics lightsource has been designed to eliminate the IR light above 700nm.
