FEMTO LDV Z8 Femtosecond Surgical Laser (K213559): indications, design and recorded evidence

The acquired K213559 file contains product-specific indications and users, design and operating principle, recorded comparison and differences, non-clinical evidence actually described, performance evidence actually described, clinical evidence or its stated absence sections. Compare these dated manufacturer statements with your own indication and design before commissioning evidence work. They describe this submission; they do not prescribe your testing, validate performance independently or establish a suitable predicate.

Evidence retrieved 2026-10-07. Source versions and topic-specific limits are listed below.

Source limits that change the comparison

The ophthalmic procedure scope needs an explicit comparison

The recorded laser indication includes corneal incisions for LASIK, ring tunnels, implant pockets and keratoplasty-related procedures. It also describes capsulotomy, phacofragmentation and corneal cuts or incisions during cataract surgery. These named procedures must stay with the comparison. [2]

Prepare or ask: Specify which proposed corneal or cataract procedure and operating mode are in scope. Compare exact labeling, surgical workflow and design evidence rather than inferring eligibility from the phrase ophthalmic laser.

Dated manufacturer-submitted summary; current buyer applicability remains unresolved. PDF page 6 ↗

The change list is more specific than a generic software update

The summary lists second-source laser cavities, adjusted power sensors, a structured laser-exit window, vacuum-system changes, handpiece/procedure-pack geometry changes and a software release incorporating changes. Those recorded modifications need their own configuration comparison. [2]

Prepare or ask: Prepare a change matrix covering cavity sourcing, power measurement, optical registration, vacuum checks, handpiece/pack geometry and software. Ask which existing versus new verification evidence supports each actual change; do not infer a universal testing exemption.

Computed exact-code research

This decision beside its recorded product-code cohort

The 2021–2025 complete-year cohort contains 8 selected decisions under primary code OOE. 8 have valid reported receipt/decision pairs; 0 pairs are missing or invalid.

No quartiles are displayed: this complete-year cohort has fewer than 20 valid pairs.

The table shows the named decision and up to four latest exact-code research records through 2026-09-27. It can include partial-year records outside the complete-year cohort. The quartiles above use the full stated cohort, not this displayed selection.

Use this comparison: select a record to investigate, read its actual indications and design, and document differences. A shared code or elapsed period cannot establish its relevance to your device.

Calendar elapsed days are not active FDA review time, a promised schedule or a success probability. The selection includes only the stated recorded decisions, not all applications. Latest records can postdate the named historical decision and are contextual research, not its predicates. Shared codes, summaries and observed records do not prove equivalence, current market availability, buyer applicability or predicate suitability.

Calculation, selection and source versions

Reuse the complete-endpoint exact-primary-code, documented SE-decision cohort and its stated cutoff/window. Retain its type-7 quartiles only when at least 20 valid date pairs are present. Independently subtract the named official record’s receipt date from its decision date; missing or negative pairs remain unknown. Show up to four latest exact-code research records, excluding the named ID. Parent analysis hash, source snapshots and calculation versions are retained.

Calculation: fda-named-decision-cohort-context-1; cutoff 2026-09-27; 0 parent records excluded; units record counts; calendar elapsed days.

Recorded evidence and differences to investigate

The summary is manufacturer-submitted context hosted by FDA. Negative/no-study statements are preserved. Evidence themes are not binding legal requirements.

Short opening excerpts identify the source sections. Read the linked original for the full study context, negative statements, tables and limitations. Public quotations are limited to 120 words per acquired summary; the internal evidence packet retains exact section ranges for review.

Indications and users

K213559 · PDF page 6 ↗ Source 2

Read this statement in the original PDF; no complete statement fits the short excerpt.

Compare with your product: Compare the recorded indication, population, body site and use environment with your proposed label. Record each change instead of assuming the primary code settles intended use.

Design and operating principle

K213559 · PDF page 4 ↗ Source 3

The FEMTO LDV™ Z8 Femtosecond Surgical Laser is a solid state femtosecond laser used in ophthal-
mology.

The excerpt is shortened at a complete statement. Read the complete section in the original PDF before interpreting the evidence.

Compare with your product: Compare physical design, materials, energy, accessories and operating principle with your design. Ask which documented differences change the evidence scope.

Recorded comparison and differences

K213559 · PDF page 6 ↗ Source 2

Read this statement in the original PDF; no complete statement fits the short excerpt.

Compare with your product: The summary’s comparison is a manufacturer statement about that submission. Investigate the actual design differences and cited records before considering any comparator or predicate.

Non-clinical evidence actually described

K213559 · PDF page 11 ↗ Source 4

Read this statement in the original PDF; no complete statement fits the short excerpt.

Compare with your product: Treat these as documented evidence themes in this case, including any limitations or negative statements. Ask which protocols, design inputs and acceptance rationale would be justified for your product; these excerpts are not a mandatory test panel.

Performance evidence actually described

K213559 · PDF page 11 ↗ Source 4

Read this statement in the original PDF; no complete statement fits the short excerpt.

Compare with your product: The source labels this section as performance data. Determine which described evidence is bench, software, biological or clinical from the actual narrative and original tables; the section label alone does not settle that distinction or prescribe your testing.

Clinical evidence or its stated absence

K213559 · PDF page 11 ↗ Source 4

Read this statement in the original PDF; no complete statement fits the short excerpt.

Compare with your product: Preserve whether the summary describes clinical evidence or says none was performed. This recorded case does not determine whether your product needs clinical evidence.

Extraction selection and limits

Select observed whole-line section headings or explicit colon-delimited inline labels on readable PDF pages, including the explicitly documented heading-spacing variants in this parser version. Preserve the original heading, character ranges and layout; do not repair excerpt text. Exclude letter boilerplate and uncertain pages. Stop at observed table headings; do not infer table columns or scalar results from layout text. Multi-column or suspicious split-numeric excerpts are excluded until reviewed alternate extraction is available. Original layout records remain retained; any alternate text has its own extractor-version locator and requires original-page review. For each dimension, prefer usable versioned alternate text where available, selecting its longest usable excerpt; otherwise select the longest usable original-layout excerpt. Ties preserve source order. Bounded to 64 PDF pages and 3,500 characters per section. This is a selection, not a complete dossier analysis.

Excluded extraction items: {}.

Prepare a differences and evidence worksheet

Use this checklist to gather your business or product details before speaking with a specialist. The items below explain what to record and suggest useful supporting documents. You can add your own answers in the editable project brief.

  1. Indications and users — what differs in our product?

    Compare the recorded indication, population, body site and use environment with your proposed label. Record each change instead of assuming the primary code settles intended use.

    Useful evidence: Our proposed indication, user/population and use environment beside this exact recorded indication.

  2. Design and operating principle — what differs in our product?

    Compare physical design, materials, energy, accessories and operating principle with your design. Ask which documented differences change the evidence scope.

    Useful evidence: Design description, materials/components, accessory list and a differences matrix.

  3. Recorded comparison and differences — what differs in our product?

    The summary’s comparison is a manufacturer statement about that submission. Investigate the actual design differences and cited records before considering any comparator or predicate.

    Useful evidence: Feature-by-feature differences and the underlying cited documents; no automated predicate selection.

  4. Non-clinical evidence actually described — what differs in our product?

    Treat these as documented evidence themes in this case, including any limitations or negative statements. Ask which protocols, design inputs and acceptance rationale would be justified for your product; these excerpts are not a mandatory test panel.

    Useful evidence: Existing protocols/results and design-specific evidence gaps, with standard editions and scope reviewed separately.

  5. Performance evidence actually described — what differs in our product?

    The source labels this section as performance data. Determine which described evidence is bench, software, biological or clinical from the actual narrative and original tables; the section label alone does not settle that distinction or prescribe your testing.

    Useful evidence: The cited narrative and full tables, underlying protocols/results and a reviewed comparison with the proposed product.

  6. Clinical evidence or its stated absence — what differs in our product?

    Preserve whether the summary describes clinical evidence or says none was performed. This recorded case does not determine whether your product needs clinical evidence.

    Useful evidence: Your proposed claims and supporting evidence, plus a reviewed rationale for clinical-evidence needs.
