VISULAS combi is intended for use in photocoagulating and photodisrupting ocular tissues in the treatment of diseases of the eye, including:
• Photocoagulation of the retina

• Trabeculoplasty
• · Iridotomy
• · Posterior capsulotomy
  · Posterior membranectomy

This device is Prescription Use (Rx) only.

VISULAS combi is an ophthalmic laser used for standard photocoagulation treatments of ocular tissue with 532 nm wavelength and standard photodisruption treatments of ocular tissues at a wavelength of 1064 mm. VISULAS combi is operated in the following treatment modes:

• single-spot mode (software license VERTE) -
• multi-spot mode (software license VITE)
• YAG disruption mode (software license YAG). -

VISULAS combi consists of a laser console, touch control panel, optional laser light applicators such as laser slit lamp or laser indirect ophthalmoscope, foot switch and instrument table. The device can also be used with various accessories, such as SL Imaging Solution, contact lenses or Applanation Tonometer.

The provided text is a 510(k) premarket notification for the VISULAS combi ophthalmic laser. It focuses on demonstrating substantial equivalence to predicate devices rather than proving performance against specific acceptance criteria for a new device type through clinical studies. Therefore, much of the requested information, particularly regarding specific performance metrics, sample sizes for test sets, expert involvement for ground truth, MRMC studies, and detailed training set information, is not explicitly provided in this document.

However, based on the document, I can extract information related to the acceptance criteria in the context of demonstrating substantial equivalence and the types of studies performed.

Here's an analysis of the provided text:

1. A table of acceptance criteria and the reported device performance

The document primarily focuses on demonstrating substantial equivalence to predicate devices, VISULAS green (K232051) for photocoagulation and VISULAS yag (K230350) for photodisruption. The "acceptance criteria" are implied by the similarity to these predicate devices in terms of indications for use, technological characteristics, and principle of operation.

• Trabeculoplasty
• Iridotomy
• Posterior capsulotomy
• Posterior membranectomy (combines indications of both predicates) |
