The 59% Extreme H2O (hioxifilcon A) toric soft contact lens for daily wear is indicated for the correction of visual acuity in aphakic or not-aphakic persons with non-diseased eyes that are myopic or hyperopic. The lens may be worn by persons who exhibit astigmatism of 10.00 Diopters or less.

Eye care practitioners may prescribe the lens for frequent/planned replacement wear, with cleaning disinfection and scheduled replacement. When prescribed for frequent/planned replacement wear, the lens may be disinfected using a chemical disinfection system.

Device Description

59% Extreme H2O (hioxifilcon A) soft contact lenses are hemispherical shells and are available as spherical (G59 S-Thin and G59 S-Xtra) or toric (G59 Toric) lens designs. The 59% Extreme H2O (hioxifilcon A) soft contact lens is fabricated from hioxifilcon A, which is a non-ionic, copolymer of 2-hydroxyethyl methacrylate (2-HEMA) and 2,3-Dihydroxypropyl Methacrylate (Glycerol Methacrylate, GMA) and cross-linked with ethylene glycol dimethacrylate (EGDMA). It consists of 41% hioxifilcon A and 59% water by weight when immersed in normal saline solution buffered with either sodium bicarbonate or sodium perforate. The lens is available with a blue visibility handling tint, phthalocyanato (2) - (copper).

AI/ML Overview

The provided text is a 510(k) Premarket Notification for a soft contact lens and does not contain information about acceptance criteria, device performance metrics, or a study evaluating such performance.

Instead, it focuses on demonstrating substantial equivalence to a previously cleared device. Therefore, I cannot provide the requested information.

Here's why and what's missing:

No Acceptance Criteria or Performance Metrics: The document describes the device, its intended use, and argues for its substantial equivalence to another cleared product. It does not list specific performance criteria (e.g., visual acuity targets, comfort scores, lens fit parameters) that the new toric lens must meet, nor does it report data on how the device performed against such criteria.
No Study Described: There is no mention of a clinical trial or a formal study designed to assess the performance of the 59% Extreme H2O (hioxifilcon A) toric soft contact lens. The clearance is based on its similarity to an existing spherical lens, assuming similar safety and effectiveness.
No Information on Experts, Sample Sizes, or Ground Truth: Since no performance study is described, there is no information regarding sample sizes for test or training sets, data provenance, the number or qualifications of experts, adjudication methods, or the type of ground truth used.
No MRMC or Standalone Performance: These terms are relevant to assessing the performance of AI/CAD systems, which is not the subject of this 510(k) submission.

Summary of what can be extracted related to the device:

Device Name: 59% Extreme H2O (hioxifilcon A) toric soft contact lens
Intended Use: Correction of visual acuity in aphakic or not-aphakic persons with non-diseased eyes that are myopic or hyperopic, who exhibit astigmatism of 10.00 Diopters or less.
Predicate Device: 59% Extreme H2O (hioxifilcon A) spherical lens (K992692)
Basis for Clearance: Substantial Equivalence to the predicate device, differing only in design (toric vs. spherical).

To answer the questions posed, a document detailing a clinical or non-clinical performance study of the 59% Extreme H2O toric soft contact lens would be required.

510(k) SUMMARY OF SAFETY AND EFFECTIVENESS

This summary of 510(k) safety and effectiveness information is being submitted in accordance with the requirements of SMDA 1990 and 21 CFR 807.92.

The assigned 510(k) number is:	K040303
Applicant information:Date Prepared:	January 27, 2005
Name:Address:	Hydrogel Vision Corporation6447 Parkland DriveSarasota, FL 34243
Contact Person:	Donna HovanecQuality System CoordinatorHydrogel Vision Corporation
Phone number:	941-739-1382
Device information:Device Classification:	Class II
Classification Number:	LPL
Classification Name:	Lens, Soft Contact, Daily Wear
Trade Name:	59% Extreme H2O (hioxifilcon A) Soft ContactLens for Daily Wear (cast-molded, with avisibility tint)

Purpose of 510(k) Submission:

Hydrogel Vision Corporation is requesting clearance from the FDA to expand the Indications for Use for the 59% Extreme H2O soft contact lens. The lens was originally approved on October 18, 1999, under 510(k) K992692, for the indication of daily wear correction of visual acuity in aphakic and not-aphakic persons with non-diseased eyes that are myopic or hyperopic with astigmatism of 0.75 Diopters or less that does not interfere with visual acuity. We are submitting this 510(k) to expand the indication to include toric lenses. The 59% Extreme H2O (hioxifilcon A) toric soft contact lens for daily wear is indicated for the correction of visual acuity in aphakic or not-aphakic persons with non-diseased eyes that are myopic or hyperopic. The lens may be worn by persons who exhibit astigmatism of 10.00 Diopters or less. Eye care practitioners may prescribe the lens for frequent/planned replacement wear, with cleaning disinfection and

scheduled replacement. When prescribed for frequent/planned replacement wear, the lens may be disinfected using a chemical disinfection system.

Equivalent Device:

The 59% Extreme H2O (hioxifilcon A) toric soft contact lens is substantially equivalent to our already cleared 59% Extreme H2O (hioxifilcon A) spherical lens under 510(k) K992692.

Device Description:

Intended Use (Indications):

Substantial Equivalence:

The information provided in this 510(k) establishes that the 59% Extreme H2O (hioxifilcon A) toric soft contact lens differs only in design to the 59% Extreme H2O (hioxifilcon A) spherical soft contact lens and meets the requirements per section 510(k) of the act regarding substantial equivalence and does not raise different questions of safety and effectiveness than the predicate device identified above.
