The present disclosure is directed to an injector device for delivering an ophthalmic solution to a cornea of an eye. The device may include a base configured to contact part of the eye, and a needle connected to the base, wherein needle may deliver the ophthalmic solution to the cornea.

Disclosed are ophthalmic solutions such as packaging solutions for storing ophthalmic devices and lens care solutions for cleaning, disinfecting, rinsing and / or storing ophthalmic devices. The ophthalmic solutions contain at least a polymerization product obtained from a monomeric mixture comprising (a) a monomer bearing a center of permanent positive charge and (b) a non-ionic ethylenically unsaturated monomer, wherein the solution has an osmolality of at least about 200 mOsm / kg, and a pH of about 4 to about 9.

A device for dispensing ophthalmic solutions to a user's eyes comprising a container for holding ophthalmic solutions, transfer tubing attached to the container for dispensing and applying said solution and a clip attached to the container for attaching said applicator to eyeglasses. The transfer tubing is the clip by being formed into the shape of a clip for attaching said eye solution applicator to eyeglasses.

There are provided lubricious ophthalmic solutions having a pH of between about 7.0 and about 8.0, consisting essentially of an aqueous solution of from about 0.5–4% by weight of a monographed polyol, borate calculated as the borate equivalent of 20–100% by weight of boric acid relative to said polyol, from about 0.1 to about 1.00% by weight of monographed polysorbate, a monographed preservative and a buffer. Suitably the polyol is polyvinyl alcohol In addition to polyvinyl alcohol (hereinafter PVA) the solution may include other monographed polymers as well as monographed pharmacologically active substances.

An ophthalmic solution containing diquafosol to which a chelating agent is added, wherein the formation of an insoluble precipitate during storage and a lowering in filtration performance in a production process (a filtration / sterilization process), said insoluble precipitate formation and said lowering in filtration performance being observed in conventional ophthalmic solutions containing diquafosol, are inhibited. It is also confirmed that the ophthalmic solution containing diquafosol to which a chelating agent is added shows an improved ability to retain the effect during storage. Therefore, the present invention provides an ophthalmic solution containing diquafosol, said ophthalmic solution having stable physicochemical properties in the course of production, distribution and storage by a patient, in particular, enabling efficient filtration / sterilization in the production process, and, moreover, having an excellent ability to retain the effect during storage. Also, the present invention provides a method for preventing the formation of an insoluble precipitate from an aqueous ophthalmic solution containing diquafosol or a salt thereof, said method comprising adding a chelating agent to the aqueous ophthalmic solution.

A dispensing tip apparatus for an eye drop dispenser to administer topical ophthalmic solutions is described. The apparatus integrates an ophthalmic solution-dispensing tip with an optical gauging assembly. The tip provides continuous visual feedback about it orientation and relationship to the eye. The dispensing tip when attached to any standard topical ophthalmic solution dispensing bottle or reservoir enables the user to view a target, visually align the dispenser tip, and administer an eye drop with precision. There is also a visual feedback by which the dispenser tip is prevented from gaining too close proximity and contacting the eye, thus preventing contamination of the medication and its dispenser. The visual feedback can also contain textual or graphic information that serves as a promotional advertisement. The is assembly can be attached to the neck of an eye drop bottle or attached to the tip of an eye drop bottle.

The present invention relates to improved ophthalmic solutions that employ select B vitamins; pyridoxine and its salts; and thiamine and its salts in order to more effectively preserve solutions and to reduce the degree to which cationic preservatives will deposit on contact lenses. Ophthalmic solutions are here understood to include contact lens treatment solutions, such as cleaners, soaking solutions, conditioning solutions and lens storage solutions, as well as wetting solutions and in-eye solutions for treatment of eye conditions.

The present invention provides a preservative composition for protecting ophthalmic solutions from microbial attack comprising a combination of benzalkonium ion and polyhexamethylene biguanide (PHMB) wherein the combined concentrations of benzalkonium ion and polyhexamethylene biguanide (PHMB) in said composition is sufficient to provide protection against microbial attack when said composition is added to an ophtalmic solution as compared to said ophthalmic soulution having the same concentration of benzalkonium ion and polyhexamethylene biguanide (PHMB), alone.
