Definitions
- This invention relates to a cleansing composition for optical surfaces such as contact lenses and similar optic apparatuses.
- Cleansing compositions containing various abrasive materials have been used in the past.
- the abradant material is added to the composition to increase the effectiveness of the composition in removing undesired matter from the surface being cleaned.
- the abradants even when in fine particle form, were harsh and had a tendency to scratch optical surfaces.
- Encrustations that form on contact lenses may be proteinaceous in nature or may be lipids or other materials foreign to the eye such as lady's mascara which usually is a soap or wax in gelatin. Success in wearing and properly using contact lenses is a function of maintaining them in a clean condition without the buildup of foreign matter, particularly encrustations which physically or chemically attach to the lens surface. Buildup of such material is gradual, but will ultimately render the lens opaque. Even before the lens becomes opaque, however, the presence of encrustations on the lens causes the wearer of the lens increased discomfort and irritation.
- Hard contact lenses may be buffed to remove encrustations, but such a process requires skill and is not easily done by the user at home without the considerable danger of scratching the lens.
- the surface of a soft contact lens is particularly prone to develop encrustations and presents particularly difficult cleaning problems since soft contact lenses cannot be cleaned except by professionals and then only with limited success.
- compositions are primarily directed to disinfecting lenses and generally do not remove encrustations.
- Those compositions that have been formulated for the purpose of removing encrustations have met with limited success.
- Soft contact lenses may be divided into two broad categories, namely, hydrophilic and hydrophobic lenses.
- Hydrophobic contact lenses are usually based on elastic and flexible silicone rubber (polysiloxane), and are generally made from cross-linked dimethyl polysiloxane.
- Hydrophilic soft contact lenses are a hydrated gel, and the ability to absorb water results in swelling to a transparent soft mass of good mechanical strength which is very comfortable to the wearer.
- Hydrated gel lenses can contain: hydroxyethylmethacrylate (HEMA) or its analogs, ethylene-glycol dimethacrylate (EGMA) or its analogs, polymethylmethacrylate (PMMA) or its analogs, polyvinylpyrrolidone (PVP) or its analogs, monomers, inhibitors, traces of catalysts and water. Hydrophilic groups of these plastic lenses attract and hold large amounts of water in the gel. These virtues, however, lead to difficulties in cleaning and sterilizing the lenses.
- HEMA hydroxyethylmethacrylate
- EGMA ethylene-glycol dimethacrylate
- PMMA polymethylmethacrylate
- PVP polyvinylpyrrolidone
- Hydrophilic soft lenses may be disinfected by chemical treatment or by boiling. As indicated, neither procedure is entirely successful in removing encrustations. Some chemicals are ineffective in removing proteins, others in removing lipids. Boiling may even denature proteinaceous material on the lenses thereby attaching encrustations all the more firmly to the lenses.
- United States Patent No. 3,910,296 to Karageozian et al. discusses a method for removing proteinaceous deposits from contact lenses with the use of a protease. However, lenses may become encrusted and contaminated with other deleterious materials such as lipids which protease enzyme will not remove.
- the present invention provides a cleansing composition for cleaning optical surfaces comprising from 1 to 25% by weight of a particulate polymer which is an organic polymer, polysiloxane polymer or a mixture thereof wherein the polymer has a particle size in the range of from 1 to 600 micrometers and a Rockwell hardness in the range of from R30 to M105 or a Shore hardness in the range from A15 to D100, and a carrier comprising water and a thickener, which carrier is compatible with ocular tissue and has a viscosity sufficient to keep the particulate polymer in suspension.
- a particulate polymer which is an organic polymer, polysiloxane polymer or a mixture thereof wherein the polymer has a particle size in the range of from 1 to 600 micrometers and a Rockwell hardness in the range of from R30 to M105 or a Shore hardness in the range from A15 to D100
- a carrier comprising water and a thickener, which carrier is compatible with ocular tissue and has
- the particulate polymer is mixed with a carrier containing a thickening agent such as Carbopol (a registered trademark of B. F. Goodrich Chemical Co.), cellulose, hydroxyethyl cellulose having a molecular weight of approximately 15,000 or polyethylene glycol with a molecular weight distribution of 400 to 4000 to form a suspension.
- a carrier containing a thickening agent such as Carbopol (a registered trademark of B. F. Goodrich Chemical Co.), cellulose, hydroxyethyl cellulose having a molecular weight of approximately 15,000 or polyethylene glycol with a molecular weight distribution of 400 to 4000 to form a suspension.
- the carrier can be any ocular compatible composition in which the polymeric particulates remain in suspension. Most generally the carrier is water to which various optional ingredients may be added.
- the end product may be a fluid or may be a thixotropic ointment or gel.
- a surfactant such as Pluronic, (a registered trademark of Wyandotte Chemicals Co.), Tween, (a registered trademark of Atlas Powder Company) or Tyloxapol (registered trademark) may optionally be added to the cleaning composition to increase its effectiveness.
- Thimerosal a product of Eli ' Lilly & Co.
- sorbic acid or ethylenediamintetraacetic acid (EDTA)
- EDTA ethylenediamintetraacetic acid
- preservatives or bactericides sodium chloride
- purified water may be optionally employed as is known in the art to provide a sterile, buffered, isotonic cleaning composition for contact lenses.
- the thickening agent is preferably present in an amount to give the suspension a viscosity of between about 150 and about 1500 mPas.
- the thickener keeps the polymeric particles in suspension and any viscosity suspension that will accomplish this result may be used.
