2. Sample size used for the test set and the data provenance

  • Sample Size for Test Set: Not explicitly stated as a number of tested units for each property. The "test set" here refers to the SAUFLON New Day lens, for which various properties were measured and compared. The data provenance is from Sauflon Pharmaceuticals Ltd., United Kingdom. The studies appear to be prospective in that new measurements were taken for the subject device to compare against the known predicate device. For some aspects (e.g., stability, leachability, toxicology), the data from the predicate device's prior approval (K013649) was deemed applicable due to identical materials and processes.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

This type of information is not applicable for this submission. The "ground truth" for contact lens properties like water content, transmittance, Dk, etc., is established through standardized physical, optical, and chemical testing methods, not through expert consensus on interpretation. Toxicology and leachability tests also follow established laboratory protocols.

4. Adjudication method for the test set

Not Applicable. As mentioned above, the "ground truth" is derived from objective physical, optical, and chemical measurements and standard laboratory tests, not from subjective expert adjudication.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

No. This is a submission for a medical device (contact lens), not an AI-powered diagnostic or assistive technology. Therefore, an MRMC comparative effectiveness study involving human readers and AI is not applicable and was not performed.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

No. This is not an AI algorithm. Therefore, a standalone algorithm performance study is not applicable and was not performed.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

The "ground truth" for the comparison is based on:

  • Standardized physical, optical, and chemical measurements: For properties like water content, transmittance, Dk, refractive index, tensile strength, etc.
  • Laboratory test results: For toxicology (cytotoxicity, systemic toxicity, ocular irritation), residual monomers, and color leachability studies.
  • Manufacturing process documentation: To confirm identical processes.
  • Reference to prior FDA clearance (K013649): For established safety and efficacy of the predicate device's materials and processes.

8. The sample size for the training set

Not applicable. This is not an AI/machine learning device. There is no concept of a "training set" in this context.

9. How the ground truth for the training set was established

Not applicable. As above, there is no training set for this type of device. The ground truth for the comparison was established through objective, standardized testing and the documented equivalence to a previously cleared device.

SUBSTANTIAL EQUIVALENCE:

SAUFLON New Day® (methafilcon A) Soft (hydrophilic) Visibility Tinted Daily Disposable Contact Lens are substantially equivalent to SAUFLON 55UV (methafilcon A) Soft (hydrophilic) Visibility Tinted Contact Lenses for Daily Wear that received market clearance pursuant to K013649 and are currently marketed in the USA.

DESCRIPTION of the DEVICE:

.

The SAUFLON New Day® (methafilcon A) Soft (Hydrophilic) Visibility Tinted Daily Disposable Contact Lenses are available in an aqua visibility tint. The lens material (methafilcon A) is a hydrophilic polymer of 2-hydroxyethyl methacrylate

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

(HEMA) and methacrylic acid, which is cross-linked with ethyleneglycol dimethacrylate. When hydrated the lens consists of 45% HEMA and 55% water by weight of saline immersed in normal saline. The lens is visibility tinted aqua with weight of summe inimelod in his meller on the well and one UV absorbing monomer is used to block UV radiation. Sauflon New Day lenses are daily disposable lenses.

The average transmittance characteristics are less than 10% in the UVB range of 280 to 315nm and less than 40% in the UVA range of 315-380nm.

The SAUFLON New Day Daily Disposable Lens is a hemispherical flexible shell, which covers the cornea and a portion of the adjacent sclera, with the following dimensions:

Chord Diameter:14.0mm to 15.0mm
Centre Thickness @ -3.00DS:0.07mm
Base Curve:8.70mm

The table overleaf Table 7.1 Comparison of Physical / Optical Properties and Processes for the SAUFLON NEW DAY (methafilcon A) Soft (Hydrophilic) Daily Disposable Visibility Tinted contact lens VS. Sauflon 55UV (methafilcon A) Soft Disposable + Inted Contact Lens for Daily Wear shows the rationale for (11) and the Saufloon the predicate device Sauflon 55UV and the Sauflon New Day Lens.

This substantial equivalence is based on the lens having the same indications for use, being equivalent in terms of performance and sharing the same chemical composition while utilising the same manufacturing method, sterilisation and packaging processes. Wheelers material Methafilcon A utilised by both predicate and test device was shown to be non-toxic in all cytotoxicity, systemic toxicity and ocular irritation tests as well as no residual monomers or dyes being present during leachability studies. as no reciente device Sauflon 55UV has an established shelf-life of 5 years based on both accelerated and real time stability studies presented in K013649 The rationale for these studies being applicable to the Sauflon New Day is that the same materials and processes are used for manufacture and packaging and there is no reason to believe that this lens cannot exceed the already established shelf-life. The lens do vary in design in that the Sauflon 55UV lens is of spherical design while the Sauflon New Day lens is aspheric. This design alteration does not affect the safety or the efficacy of the lens. The design engineering drawing for the aspheric design is included in Section 8 of this submission.

Due to the varying modality of the predicate i.e. a daily wear lens and subject lens i.e. a daily disposable lens the labelling of the package insert does vary in that the package insert for a daily disposable is not required to contain as much detail as a daily wear lens requires. Items such as a cleaning and care regime for the lenses are not required as the New Day lens is disposed of following use.

The package insert does however contain all necessary information for the safe and effective use of a daily disposable lens including lens handling, insertion, removal and precautions.

The final draft labelling for the Sauflon New Day lens blister pack, carton, patient instructions and professional fitting and information guide are included in Section 5 of this submission. The patient instructions for the predicate device are included in Section 6 of this submission.

PRECLINICAL TESTING

The results of toxicology testing (cytotoxicity, acute systemic toxicity and acute ocular irritation) show the lens material methafilcon A to be non-toxic and nonirritating. Furthermore, the results of residual monomer and colour leachability testing demonstrate that the respective extracts did not contain significant levels of leachable colour or residual monomers.

The physical optical, and chemical properties of the SAUFLON New Day® Daily Disposable Lenses (methafilcon A) Soft (Hydrophilic) Visibility Tinted Contact Lens are equivalent to those of Sauflon 55 UV (methafilcon A) Soft Hydrophilic Visibility Tinted Contact Lens for Daily Wear. This lens is in group 4, Ionic, high water content polymers as established by the FDA and located in the Guidance Document for Daily Wear Contact Lenses, Revised Edition May 1994.

The lens will be sterilised and packaged in the same manner as previously cleared in K013649. This lens will also be sterility released by parametric release, as cleared in K013649.

INDICATIONS FOR USE

The SAUFLON New Day® Daily Disposable Lenses (methafilcon A) Soft (Hydrophilic) Visibility Tinted Contact Lens is a daily disposable lens indicated for the correction of the refractive ametropia (myopia and hyperopia) and astigmatism in aphakic and not-aphakic persons with non-diseased eyes that may exhibit astigmatism up to 2.00 Dioptres that does not interfere with visual acuity.

The predicate device Sauflon 55UV lens is prescribed for daily wear however the Sauflon New Day is a Daily Disposable lens.

The New Day lens is a convenient alternative to a daily wear lens as the patient can dispose of the lens at the end of the day and then insert a brand new pair the next morning.

This eliminates the need for the patient to carry out a cleaning regime for the lens and the risk of experiencing contact lens related problems is reduced due to the limited exposure time of using one particular set of lenses.
