Study Details:
-
Sample size used for the test set and the data provenance:
- Test set sample size: "Seventy-five (75) patients were enrolled in the study (56 test/19 control)."
- Data provenance: Not explicitly stated, but clinical studies for such devices are typically conducted in the country where the device is seeking regulatory clearance. Given the 510(k) summary submitted to the FDA, it's highly probable the study was conducted in the United States.
- Retrospective or prospective: The clinical study was described as "A three month clinical study was conducted...", indicating a prospective study design.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. For contact lens safety and efficacy studies, the "ground truth" is established through direct observation of physiological responses and visual acuity measurements in patients, rather than expert interpretation of images or other data. The study primarily evaluated safety and efficacy through clinical observation by eye care professionals.
-
Adjudication method for the test set: Not applicable in the context of an adjudication method typical for image-based diagnostic AI studies. Safety and efficacy were assessed through direct clinical observations and measurements over a three-month period.
-
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: Not applicable. This study is for a contact lens, not an AI-powered diagnostic device, so an MRMC study is not relevant.
-
If a standalone (i.e., algorithm only without human-in-the-loop performance) was done: Not applicable. This study is for a physical medical device (contact lens), not an algorithm.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc.): The ground truth for this device's performance relies on clinical outcomes data from the three-month study, including patient safety (e.g., adverse events, ocular irritation) and efficacy (e.g., satisfactory visual acuity, correction of refractive errors, comfort).
-
The sample size for the training set: Not applicable. This study is for a contact lens, which does not involve a "training set" in the context of machine learning or AI. The physical properties and design are based on manufacturing processes and material science, not trained algorithms.
-
How the ground truth for the training set was established: Not applicable, as there is no "training set" for this device.

(a)
Identification. A soft (hydrophilic) contact lens is a device intended to be worn directly against the cornea and adjacent limbal and scleral areas of the eye to correct vision conditions or act as a therapeutic bandage. The device is made of various polymer materials the main polymer molecules of which absorb or attract a certain volume (percentage) of water.(b)
Classification. (1) Class II if the device is intended for daily wear only.(2) Class III if the device is intended for extended wear.
(c)
Date PMA or notice of completion of a PDP is required. As of May 28, 1976, an approval under section 515 of the act is required before a device described in paragraph (b)(2) of this section may be commercially distributed. See § 886.3.
