Intended Use

Boston® Enhanced Original Formula Conditioning Solution is indicated for use in wetting, disinfecting and soaking after cleaning and rinsing of fluoro silicone acrylate and silicone acrylate rigid gas permeable contact lenses.

Device Story

Boston Enhanced Original Formula Conditioning Solution is a sterile, buffered, chemical solution preserved with chlorhexidine gluconate and edetate disodium. Used by patients for the care of rigid gas permeable (RGP) contact lenses; specifically for wetting, disinfecting, and soaking lenses after cleaning and rinsing. The solution maintains lens surface wettability, as demonstrated by dynamic contact angle analysis, and ensures lens compatibility with silicone acrylate and fluoro silicone acrylate materials. It functions as a chemical maintenance agent to support lens hygiene and comfort during wear.

Clinical Evidence

Controlled clinical study involving 212 eyes (106 patients) across 7 investigators. Study compared the modified solution to the predicate Boston Conditioning Solution. Analysis of data using descriptive statistics, tests for normality, and ANOVA/t-tests showed no clinically significant differences in safety or efficacy between test and control groups.

Technological Characteristics

Sterile, buffered aqueous solution. Preservatives: chlorhexidine gluconate and edetate disodium. Formulated for compatibility with fluoro silicone acrylate and silicone acrylate RGP lenses. Evaluated for wettability via dynamic contact angle (DCA) analysis. Meets ISO and FDA performance criteria for contact lens care products.

Indications for Use

Indicated for wetting, disinfecting, and soaking of fluoro silicone acrylate and silicone acrylate rigid gas permeable contact lenses.

Regulatory Classification

Identification

A rigid gas permeable contact lens care product is a device intended for use in the cleaning, conditioning, rinsing, lubricating/rewetting, or storing of a rigid gas permeable contact lens. This includes all solutions and tablets used together with rigid gas permeable contact lenses.

|----------------------|---------------------------------------------------------|
| Proprietary Name: | Boston® Enhanced Original Formula Conditioning Solution |
| Common Name: | Contact Lens Conditioning Solution |

#### 4. PREDICATE DEVICE:

The currently marketed Boston® Conditioning Solution, approved under PMA P820070 on November 17, 1983, has been selected as the predicate device for the modified Boston® Enhanced Original Formula Conditioning Solution.

#### 5. DESCRIPTION OF THE DEVICE:

The modified Boston® Enhanced Original Formula Conditioning Solution is a sterile conditioning solution used in the care of rigid gas permeable contact lenses and is indicated for the wetting, disinfecting and soaking after cleaning and rinsing of fluoro silicone acrylate and silicone acrylate contact lenses. This product is a sterile, buffered solution, preserved with chlorhexidine gluconate and edetate disodium.

#### 6. INDICATIONS FOR USE:

The modified Boston® Enhanced Original Formula Conditioning Solution is indicated for use in the wetting, disinfecting and soaking after cleaning and rinsing of fluoro silicone acrylate and silicone acrylate rigid gas permeable contact lenses.

#### 7. DESCRIPTION OF SAFETY AND SUBSTANTIAL EQUIVALENCE:

A series of preclinical testing was performed to demonstrate the safety and effectiveness of the modified Boston® Enhanced Original Formula Conditioning Solution. A summary of the results from the preclinical tests is presented below.

### Toxicology:

### In-Vitro Cytotoxicity:

USP Agar Diffusion Cytotoxicity was completed in accordance with USP XXII. The test article meets the requirements of the Agar Diffusion Test.

### Acute Ocular Irritation:

Acute Ocular Irritation test was performed and produced no ocular irritation. The solution did not cause any significant irritation to the ocular tissues of the laboratory animals.

### Microbiology:

### Preservative Effectiveness:

Studies were performed to evaluate the preservative efficacy of the modified Boston® Enhanced Original Formula Conditioning Solution in 1 oz. round containers and in 4 oz. oval containers. The results of these tests demonstrate that the modified Boston® Enhanced Original Formula Conditioning Solution meets the requirements of the Premarket Notification (510(k)) Guidance Document for Contact Lens Care Products. May 1, 1997 and the ISO Draft Standard.

The results of all testing demonstrated that the safety and effectiveness of the modified Boston® Enhanced Original Formula Conditioning Solution is equivalent to the currently marketed Boston® Conditioning Solution.

{2}------------------------------------------------

Disinfection Efficacy:

The ISO FDA Regimen Procedure for Disinfecting Regimens was performed to evaluate the disinfecting efficacy of the modified Boston® Enhanced Original Formula Conditioning Solution. The results of this evaluation demonstrate that the product meets the FDA performance criteria for regimen evaluation as described in the Premarket Notification (510(k)) Guidance Document for Contact Lens Care Products, May 1, 1997, and the Draft Premarket Notification (510(k)) Guidance Document for Contact Lens Care Products, April 1, 1996.

## Shelf Life:

Expiration dating will be established based on the Shelf-life Protocol in accordance with the Premarket Notification (510(k)) Guidance Document for Contact Lens Care Products, May 1, 1997, and the Draft Premarket Notification (510(k)) Guidance Document for Contact Lens Care Products, April 1, 1996.

## Solution Compatibility:

BOSTON IV (silicone acrylate) and BOSTON ES (fluoro silicone acrylate) tinted rigid gas permeable contact lenses were subjected to thirty repeated cvcles with Boston Cleaner and the modified Boston® Enhanced Original Formula Conditioning Solution.

After thirty repeated cycles with Boston Cleaner and the modified Boston® Enhanced Original Formula Conditioning Solution, all of the physical and lens parameters tested for BOSTON IV and BOSTON ES rigid gas permeable tinted contact lenses were within ISO specifications for rigid corneal and scleral contact lenses. There was no change in the cosmetic appearance.

# Wetting Angle:

This study evaluated the retention of the modified Boston® Enhanced Original Formula Conditioning Solution and the currently marketed Boston Conditioning Solution on two selected RGP lens materials. BOSTON IV (silicone acrylate) and BOSTON ES (fluoro silicone acrylate) tinted rigid gas permeable contact lenses. Dynamic contact angle (DCA) analysis was the method chosen to measure the desorption of solution from the lens material surface. The results of the DCA testing indicate that the modified Boston® Enhanced Original Formula Conditioning Solution maintains the wettability of the surface better than the currently marketed Boston Conditioning Solution.

{3}------------------------------------------------

#### 8. SUBSTANTIAL EQUIVALENCE:

The modified Boston® Enhanced Original Formula Conditioning Solution is substantially equivalent to the currently marketed Boston Conditioning Solution, approved November 17, 1983 under PMA P820070, in that both products are formulated similarly, with the same indications, usage, and aspects of manufacturing.

#### 9. CLINICAL:

The purpose of this study is to demonstrate that the modified Boston® Enhanced Original Formula Conditioning Solution is substantially equivalent in safety and efficacy to the currently marketed BOSTON Conditioning Solution when used with currently marketed silicone acrylate and fluoro-silicone acrylate rigid gas permeable contact lenses. This controlled clinical study was designed in accordance with the Premarket Notification (510(k)) Guidance Document for Contact Lens Care Products, Mav 1. 1997.

A total of 212 eyes (106 patients) were entered into the study by 7 Investigators. Of the 212 eves (106 patients) enrolled. 36 eves (18 patients) were non-dispensed.

The data from the study were examined using descriptive statistics. tests for normality, analysis of variance and/or t-tests where appropriate. Analysis of all data from this study showed no clinically significant differences between the Test and Control Groups.

Based on these data, the Sponsor concludes that the modified Boston Enhanced Original Formula Conditioning Solution is substantially equivalent in safety and efficacy to the currently marketed Boston Original Conditioning Solution.
