• Attributes: Therapeutic

Intended Use

The intended use of this device is to assist in the automated phacoemulsification of a natural crystalline lens.

Device Story

Device consists of hollow titanium alloy ultrasonic tips for phacoemulsification systems; used to emulsify and aspirate cataractous lens material. Electronic energy from console converts to ultrasonic energy at handpiece tip; irrigation fluid delivered via sleeve; emulsified material aspirated through tip center. Designed for up to 20 uses; requires inspection before/after each procedure. Used in ophthalmic surgery by surgeons. Benefits include repeated use capability for previously single-use tips, maintaining performance standards for safety and efficacy.

Clinical Evidence

Bench testing only. Performance data demonstrated that repeated use of the tips does not alter performance or affect safety and efficacy. Effects of fatigue, cavitation erosion, and chemical reactions were evaluated and shown to have no significant effect on tip performance.

Technological Characteristics

Titanium alloy ultrasonic tips; hollow needle form factor. Energy source: ultrasonic energy generated by external console. Connectivity: mechanical interface to phacoemulsification handpiece. Sterilization: reusable (requires reprocessing).

Indications for Use

Indicated for patients undergoing automated phacoemulsification of a natural crystalline lens.

Regulatory Classification

Identification

A phacofragmentation system is an AC-powered device with a fragmenting needle intended for use in cataract surgery to disrupt a cataract with ultrasound and extract the cataract.

#### 2. Device Description

The Series 20000® Legacy® System and its predicate devices use ultrasonic energy to emulsify cataractous lens material and remove it from the eye (phacoemulsification). Electronic energy is generated in the machine, delivered to a handpiece and is finally converted to ultrasonic energy delivered through a hollow titanium needle, or tip. Irrigation fluid is delivered to the eye via the combination of an irrigation sleeve over the handpiece tip. The emulsified lens material is aspirated out of the eye through the center of the handpiece/tip assembly. The handpieces are being routinely used repeatedly in multiple surgical procedures, while the tips marketed by Alcon have been labeled for single-use only. Other predicate devices have been labeled as reusable. The labeling modification which is the subject of this submission is that some of Alcon phacoemulsification tips can be used in up to 20 surgical procedures, provided they are carefully handled and inspected before and after each use.

#### 3. Intended Use of the Device

The intended use of this device is to assist in the automated phacoemulsification of a natural crystalline lens.

### 4. Summary of the Technological Characteristics of the Device

The Alcon Limited Reuse Tips utilizes the same technology as the predicate devices. The tips are manufactured from a titanium alloy which exhibits excellent structural and chemical properties making it suitable for repeated use in surgical procedures.

{2}------------------------------------------------

# 5. Summary of the Performance Data

It has been demonstrated that repeated use of the phacoemulsification tips does not alter performance of the tips as to affect safety and efficacy of the device. Specifically, effects of fatigue, cavitation erosion, and chemical reactions have been shown to have no significant effect on tip performance.

### 6. Conclusions

Therefore, based on the data provided in this Premarket notification, the Alcon Limited Reuse Phacoemulsification Ultrasonic Tip is proven to be substantially equivalent to the predicate devices described in Section 1 (above).
