Intended Use

The FemTec™ Laser Microkeratome is indicated for use in the creation of a corneal flap in patients undergoing LASIK surgery or other treatment requiring initial lamellar resection of the cornea.

Device Story

FemTec Laser Microkeratome creates corneal flaps for LASIK or lamellar resection. Device uses femtosecond laser pulses (500-1000 fs) to induce optical breakdown (LIOB) in corneal tissue. Laser energy delivered through disposable PMMA patient interface (PI) under low vacuum (250 mbar). Microscopic gas bubbles form at pre-determined depths, creating a continuous lamellar dissection plane similar to mechanical microkeratome blades. Operated by clinicians in surgical settings. Output is a surgically created corneal flap, facilitating subsequent refractive correction. Benefits include precise, non-mechanical lamellar resection.

Clinical Evidence

Bench testing to applicable safety standards performed. Ex vivo study demonstrated performance equivalence to the Hansatome Microkeratome regarding the creation of a corneal flap.

Technological Characteristics

Laser surgical instrument; femtosecond laser (500-1000 fs pulse duration); disposable PMMA patient interface; low vacuum (250 mbar) suction system; creates lamellar corneal dissection via laser-induced optical breakdown (LIOB).

Indications for Use

Indicated for patients undergoing LASIK surgery or other procedures requiring initial lamellar resection of the cornea.

Regulatory Classification

Identification

| B. | Trade/Proprietary Name: | FemTec™ Laser Microkeratome |

## 3. SUBSTANTIAL EQUIVALENCE

The FemTec™ Laser Microkeratome is of comparable type and is substantially equivalent to the following predicate devices:

{1}------------------------------------------------

| Predicate Device | Manufacturer | 510(k) No. | Date Cleared |
|------------------------------|---------------------------|------------|-------------------|
| Pulsion FS Laser<br>Keratome | Intralase Corp. | K013941 | February 27, 2002 |
| Hansatome<br>Microkeratome | Bausch & Lomb<br>Surgical | K010260 | April 27, 2001 |

The materials, basic scientific concepts, and physical properties of the FemTec Laser Microkeratome are similar to those of the Intralase Pulsion FS Laser Keratome (and the indications for use are identical), and the indications for use for the FemTec Laser Microkeratome are identical to those of the Hansatome Microkeratome.

#### 4. DEVICE DESCRIPTION

The FemTec Laser Microkeratome is intended for use in the creation of a corneal flap by producing short bursts of laser pulses, with each laser pulse having a duration on the order of 500 to 1000 femtoseconds ("fs", 10-15 seconds). Microscopic gas bubbles, which form as a result of the laser induced optical breakdown (LIOB), arc created adjacent to each other at a pre-determined depth in the cornea. It is this continuous layer of gas bubbles that create the lamellar corneal dissection plane just like a mechanical microkeratome blade. The FemTec Laser Microkeratome creates a flap under very low vacuum (250 mbar), and delivers the laser energy directly to the stromal layer of the cornea through a disposable PMMA contact lens, referred to as the Patient Interface (PI).

#### 5. INDICATIONS FOR USE

The FemTecTM Laser Microkeratome is indicated for use in the creation of a corneal flap in patients undergoing LASIK surgery or other treatment requiring initial lamellar resection of the cornea

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

#### 6. TECHNOLOGICAL CHARACTERISTICS

The 20/10 Perfect Vision FemTec™ Laser Microkeratome has technological characteristics very similar to those of the Intralase Pulsion FS Laser Keratome. The design, materials, and characteristics of the FemTec™ Laser Microkeratome are similar to those of the Pulsion FS Laser Keratome. The differences between the FemTec™ Laser Microkeratome and the Pulsion FS Laser Keratome are insignificant and do not affect the safety or effectiveness of the device.

## PERFORMANCE DATA SUMMARY 7.

The FemTec™ Laser Microkeratome has been designed and will be tested to applicable safety standards. In addition, the FemTec™ Laser Microkeratome was found to perform equivalently to the Hansatome Microkeratome with respect to the creation of a corneal flap in an ex vivo study.

#### 8. CONCLUSIONS

20/10 Perfect Vision GmbH has demonstrated through its evaluation of the FemTec™ Laser Microkeratome that the device is equivalent to the predicate devices with respect to intended use, technological characteristics, and safety and effectiveness.
