A method for tracking ophthalmic lens care compliance, said method comprising the steps of: including at least one sensor with said ophthalmic product for monitoring at least one ambient condition and for logging and recording at least one reading associated said at least one ambient condition, following a predetermined event; determining whether said at least one reading exceeds at least one predetermined threshold, and issuing an alert when said at least one reading exceeds at least one predetermined threshold.

The invention relates to an ophthalmic product which has a capability of delivering a guest material (e.g., a lubricant or a drug) in a time-controlled-releasing manner. The invention also provides a process for making an ophthalmic product of the invention. In addition, the invention provides a method for time-controlled delivery of a drug or a lubricant.

A method for tracking the wearable life of an ophthalmic product, the method comprising the steps of: providing the ophthalmic product with at least one data carrier for carrying data related to the ophthalmic product, the data carrier having a first device operable in a magnetic and/or electrical mode; providing an activation signal from an external means; activating the first device with the activation signal to cause the first device to emit the data in response to the activating signal; recording the time the first device is interrogated, processing the received data to determine the wearable life of the ophthalmic product based on the lapsed time.

Disclosed are novel light polarizing articles comprising a substrate, a light polarizing layer, an inorganic intermediate layer between the polarizing layer and the substrate, an optional inorganic sub-layer between the substrate and the inorganic intermediate layer, and a protective layer over the light polarizing layer, and method of making the same. Due to the presence of the inorganic intermediate layer and the optional sub-layer, adhesion of the polarizing layer is improved substantially. The light polarizing article has improved chemical, mechanical and thermal resistance. The light polarizing article can be used, for example, as ophthalmic products and in display devices.

Disclosed herein are light polarizing articles that include a substrate, a light polarizing layer disposed on a surface of the substrate, a thick polymer layer disposed on the light polarizing layer, and at least one anti-scratch layer disposed on the thick polymer layer. The thick polymer layer serves as a buffer layer that, when combined with a thin abrasion-resistant coating, permits substantially improved resistance to scratching and indentation. The improved indentation resistance is exhibited even when being indented with sharp objects. The light polarizing articles can be used, for example, as ophthalmic products and in display devices. Methods of making and using the light polarizing articles are also disclosed.

This invention relates to the preparation of molds for the production of contact lenses and other ophthalmic articles. By using an inorganic material to coat the optical surfaces and sidewalls of mold parts made from clear-resin materials, manufacturers can produce lens molds with greater dimensional stability and chemical resistance. In addition to protecting the clear resin from interaction with otherwise reactive monomers from which the molded article is made, such coatings can also be used to achieve preferential release of the molded article. The resulting mold is especially useful for providing an economical way to improve manufacturing quality of contact lenses.

Fluid is drained from a bleb using a device including a tubular member having opposed open ends to enable the fluid to flow from end to end through the tubular member. Inward from one end is a stop element enabling the one end to be inserted in one direction through a wall of the bleb but preventing the inserted end from being pulled in the opposite direction through the bleb wall. The opposed remote end of the tubular member is inserted into the retrobulbar space to enable fluid exiting the tubular member at this remote end to drain into the tissue. Along an exterior of the tubular member is an anchoring element enabling the device to be sutured in position. An ophthalmic product has a bleb drainage feature.

The invention relates to a sterile, drop-forming, multi-phase, emulsifier-free ophthalmic product, in particular a gel product, comprising at least one liquid aqueous phase and at least one liquid hydrophobic phase, the product comprising at least one phosphate salt and having a viscosity in the range from > 200 mPa<.>s to < 2000 MPA<.>s.

A system for determining the presence and optionally the position of an ophthalmic product such as a contact lens in a container is provided.

The present invention discloses use of a compostion of poylmers with high refractive index in ophthalmological devices and preparation thereof.

The invention discloses a pharmaceutical composition. The pharmaceutical composition comprises tiaprofen acid and soy isoflavone, and the mass ratio of tiaprofen acid to soy isoflavone is 1: (0.5-2).The pharmaceutical composition can be further prepared into ophthalmic products, including ophthalmic injections, eye drops, ophthalmic gels, ophthalmic ointments and the like; and the tiaprofenic acid can further reduce inflammatory response accompanied by fundus diseases, and meanwhile, it is accidentally that the tiaprofenic acid can also serve as a penetration enhancer to improve the intraocular permeability of the soy isoflavone, so that under the condition that the treatment effect is not changed, the use dosage of the soy isoflavone is reduced, and a relatively great application prospect is achieved.

Provided is an ophthalmic product obtained by: housing, in a container, an ophthalmological composition comprising (A) an easily-oxidizable substance, (B) a refreshing agent, (C) a non-ionic surfactant, and (D) at least one component selected from dibutyl hydroxytoluene, dibutyl hydroxyanisole, propyl para-hydroxybenzoate, butyl para-hydroxybenzoate, and chlorobutanol; and enclosing and sealing, by an enclosing body, the container together with an iron-based oxygen absorber. Regarding the ophthalmic product, the capacity of the main body thereof is 1-25 mL, the oxygen permeability of the mainbody is at least 10 cc/(m2 24 hr atm), and the volume of space formed between the enclosing body and the container is at most 200 V/V% with respect to the volume of the container.
