Definitions
- the present invention relates to a siloxane monomer used in the manufacture of a silicone hydrogel lens, a composition for preparing a lens comprising the same, and a silicone hydrogel lens prepared therefrom, wherein the silicone hydrogel lens according to the present invention is a mold without a separate solvent. ) It is easy to release from the surface of parts.
- Various contact lenses have been commercially manufactured for many years. Early contact lenses were made of hard materials and these lenses are still used in some applications today but are not suitable for all patients because of their poor fit. Since then, soft contact lenses based on hydrogels have been developed and are very popular today. These lenses can be manufactured by molding the lens in a mold. For example, it may include a first mold part having a convex surface corresponding to the back curved surface of the ophthalmic lens, and a second mold part having a concave surface corresponding to the front curved surface of the ophthalmic lens. To produce a lens using such a mold part, an uncured hydrogel lens composition is placed between the concave and convex surfaces of the mold part and then cured. After curing, the mold parts are separated according to typical practice, and the lens remains attached to one mold part. The release process removes the lens from the remaining mold parts.
- the lens can be released from the mold by exposing the lens to an aqueous or salt solution such that the solution swells the lens and degrades the adhesion between the lens and the mold.
- U.S. Patent No. 5,258,490 discloses a method of impregnating a lens with alcohol, ketones, aldehydes, esters, amides or N-alkyl pyrrolidones in the absence of water for 20 to 40 hours, or with a mixture containing water as a minor component Is disclosed.
- Korean Patent Laid-Open Publication No. 10-2007-0080847 also discloses a method for promoting mold release by mixing polyethylene glycol (PEG) with a lens composition or material of a mold part.
- PEG polyethylene glycol
- the method using the aqueous solution is not effective for the silicone hydrogel lens containing a large amount of hydrophobic raw material silicon, and although the method using the organic solvent has been performed successfully, the use of the highly concentrated organic solution
- there may be disadvantages such as safety risks, increased risk of production line interruption, expensive release solutions, and the possibility of secondary damage due to explosion.
- the use of polyethylene glycol (PEG) may cause a problem that may affect the physical properties of the lens by the complexity of the process or mixing in the lens composition.
- the silicone hydrogel lens in the cured state has a problem in that it is difficult to separate the lens from the mold due to the material property of flexibility and surface stickiness. Therefore, various methods as described above have been proposed, but in order to solve the problem, it would be more advantageous to manufacture a lens using a silicon raw material which improved the flexibility and surface stickiness of the silicon hydrogel lens.
- An object of the present invention is to provide a siloxane monomer and a silicone hydrogel lens using the same to facilitate the release of the silicone hydrogel lens from the mold parts.
- an object of the present invention is to provide a siloxane monomer having a good release property and a water content and an oxygen permeability coefficient equivalent to those of a conventional silicone hydrogel lens and a silicone hydrogel lens using the same.
- the present inventors have studied and studied the characteristics of the soft contact lens material, and as a result, the silicone hydrogel from the components of the target mold by introducing an aromatic structure such as phenyl into the silicone raw material of the silicone hydrogel
- the present invention has been found to have improved the release property of the lens.
