Device Story

Alcon 27GA Chandelier, 27+ DS Wide Angle Endoilluminator, and 27+ DS Endoilluminator are fiber-optic surgical instruments for posterior segment ophthalmic procedures. The Chandelier provides hands-free, wide-field illumination via a malleable, tapered fiber inserted through a pars plana entry system. The 27+ DS models feature a retractable Dynamic Stiffener (DS) on the stainless-steel cannula to reduce needle deflection and a sapphire lens (Wide Angle model) for consistent, low-glare illumination. Devices are used in an operating room setting by ophthalmic surgeons. They connect to the UNITY VCS system to transmit light energy into the eye. The surgeon uses the illumination to visualize the surgical field, facilitating precise vitreoretinal maneuvers. Benefits include improved visualization, reduced glare, and enhanced surgical stability through the DS mechanism.

Clinical Evidence

No clinical data. Bench testing only. Testing included biocompatibility (ISO 10993), sterilization validation (ISO 11135), packaging integrity (ISO 11607-1, ASTM F1980, ASTM D4169), and optical performance/safety (luminous flux, aphakic/thermal irradiance per ANSI Z80.36 and ISO 15752).

Dear Ganesh Balachandar:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

### Alcon 27GA Chandelier

The Alcon 27GA Chandelier provides a hands-free wide field of illumination for vitreoretinal procedures. The distal end of the device incorporates a short, tapered fiber optic to provide wide angle illumination projected from a pars plana position of the eye. The distal end consists of a tapered fiber, which is inserted into the eye through the Alcon 27GA entry system. The fiber is malleable so the physician can shape it to form a stable service loop, position the tip, and minimize interference with the lid speculum.

### Alcon 27+ DS Wide Angle Endoilluminator

The Alcon 27+ DS WA Endoilluminator offers wide-angle illumination, featuring a sapphire lens at the distal end of the probe. This design ensures consistent, low-glare illumination across a broad field of view. Additionally, it incorporates a Dynamic Stiffener (DS) element-a retractable stiffener designed to minimize needle deflection at the proximal end of the stainless steel cannula. as opposed to the fixed stiffener used in previous models.

### Alcon 27+ DS Endoilluminator

The Alcon 27+ DS Endoilluminator transmits light energy into the eye and incorporates a DS element at the proximal end of the stainless-steel cannula.

#### SUMMARY OF STUDIES 7.

#### 7.1 Non-Clinical Testing

### Biocompatibility

Alcon conducted biocompatibility testing on the patient-contacting devices and met ISO 10993. Biocompatibility of medical devices requirements for chemical characterization, cytotoxicity, sensitization, irritation, and acute systemic toxicity. Packaging materials passed cytotoxicity requirements from ISO 11607-1, Packaging for terminally sterilized medical devices and ASTM F2475. Standard Guide for Biocompatibility Evaluation of Medical Device Packaging Materials.

### Sterilization and Shelf Life

Alcon performed sterilization testing on the subject devices. Tested devices passed the predetermined acceptance criteria in accordance with ISO 11135, Sterilization of health-care products - Ethylene oxide and ISO 10993-7, Biological evaluation of medical devices Part 7: Ethylene oxide sterilization residuals. The subject devices were sterilized by ethylene oxide (EO). The subject devices have been shown to be sterilizable to a sterility assurance level (SAL) of 10°, and the sterilization process has been validated per the required standard.

The subject devices utilize the same packaging configuration as their predicates, undergoing ethylene oxide (EO) sterilization and pre-conditioning in accordance with ASTM D4169, Standard Practice for Performance Testing of Shipping Containers and Systems. Additionally, accelerated aging was performed in compliance with ASTM F1980, the Standard Guide for Accelerated Aging of Sterile Barrier Systems and Medical Devices. All tested units successfully met the predetermined acceptance criteria for package integrity, which included visual inspection, seal strength, and bubble leak tests, in accordance with ISO 11607-1, Packaging for Terminally Sterilized Medical Devices.

### Performance Testing

Safety tests demonstrated the compliance of the subject devices to the appropriate standards. Biocompatibility evaluations of materials coming into contact with the patient fluid path demonstrated compliance with the appropriate standard from the ISO 10993 series.

Technological characteristics affecting clinical performance are similar to those of the predicate devices previously listed. Like the predicate devices have been developed and manufactured in compliance with the following standards:

- ISO 14971, Medical devices Application of risk management to medical devices ●
- ISO 15004-1, Ophthalmic instruments Fundamental requirements and test methods, Part ● 1: General requirements applicable to all ophthalmic instruments
- ISO 15752, Ophthalmic Instruments - Endoilluminators - Fundamental Requirements and Test Methods for Optical Radiation Safety

{14}------------------------------------------------

- ANSI Z80.36, Ophthalmics Light Hazard Protection for Ophthalmic Instruments ●
Light Hazard Testing:

The three subject devices were evaluated for luminous flux, aphakic irradiance and thermal irradiance for the purposes of comparison with the predicate devices and compliance to ANSI Z80.36, Ophthalmics - Light Hazard Protection for Ophthalmic Instruments and ISO 15752, Ophthalmic Instruments - Endoilluminators - Fundamental Requirements and Test Methods for Optical Radiation Safety.

The subject devices have a similar luminous flux and meet aphakic and thermal safety standards comparable to the predicate devices.

Non-clinical testing noted above has demonstrated that the functional requirements have been met and that the subject devices are equivalent to the predicate devices.

#### Animal/Clinical Testing 7.2

The risk assessment for the subject devices did not require any animal or clinical testing as mitigation against any identified risks.

#### CONCLUSION 8.

The subject devices share the same intended use as the predicate devices. Their indications for use are equivalent with each other. The technological characteristics affecting clinical performance are similar to those of the predicate devices previously listed. Risk profiles are equivalent between the subject devices and the predicate devices. The predicate devices and the subject devices have been developed and manufactured in compliance with 21 CFR 820 and ISO 14971. Non-clinical testing noted above demonstrated that the functional requirements were met, and that the subject devices are equivalent to the predicate devices.

Therefore, the subject devices, the Alcon 27GA Chandelier, Alcon 27+ DS Wide Angle Endoilluminator, and Alcon 27+ DS Endoilluminator, are deemed substantially equivalent to their predicate devices, the 25GA Chandelier, 25GA Wide Angle Endoilluminator and 27+ Straight Endoilluminator, respectively.
