Definitions

  • the instant disclosure relates to a composition for contact lenses; in particular, to a composition for contact lenses which can serve as a contact lens preservation solution.
  • Smartphones and computers are used frequently in today's information society, resulting in an increase in the population with myopia and a decrease in the age group of myopia.
  • it is generally a good choice for people with myopia to wear contact lenses.
  • most people with myopia need to wear contact lenses for extended periods of time.
  • the material of the conventional contact lenses have been constantly improved to meet various requirements such as high water content and high oxygen permeability, the wearers thereof would still suffer from eye dryness due to decreased water content and experience eye discomfort due to dirt or secretion. Therefore, there is an urgent need for a maintenance solution that can be used to clean, rehydrate and preserve contact lenses.
  • US2017056335 A1 discloses an ophthalmic composition comprising polysorbate 80 and a refreshing agent.
  • WO9603158 A1 and US 6 228 323 B1 disclose compositions for contact lenses which include sodium lauroyl lactylate.
  • One aspect of the instant disclosure relates to a composition for contact lens which allows a contact lens wearer's eyes to feel comfortable during the period of initial wear and extended periods of continuous wear.
  • the composition for contact lenses includes an algefacient and a surfactant, and a water soluble polymer, wherein the surfactant is sodium lauroyl lactylate, wherein the algefacient includes one or a combination of menthol, camphor, borneol, menthyl lactate, menthone glycerol ketal, monomethyl succinate, and p-menthane-3,8-diol; and wherein the water soluble polymer includes PEG 400 and MPC in a molar ratio of 1:20.
  • the surfactant is sodium lauroyl lactylate
  • the algefacient includes one or a combination of menthol, camphor, borneol, menthyl lactate, menthone glycerol ketal, monomethyl succinate, and p-menthane-3,8-diol
  • the water soluble polymer includes PEG 400 and MPC in a molar ratio of 1:20.
  • the algefacient and the surfactant wherein the surfactant is sodium lauroyl lactylate and the expression of the algefacient in the composition of a contact lens can be performed effectively. Therefore, the discomfort and foreign matter sensation in the eyes of contact lens wearers can be reduced or relieved, providing long-lasting cool and moist sensations to the eyes.
  • Fig. 1 is a perspective view showing a contact lens and a composition for contact lenses according to the instant disclosure in a container.
  • the instant disclosure provides a composition for contact lenses which can serve as a preservation solution and be hermetically sealed with the contact lenses in a container.
  • the contact lenses are immersed in direct contact with the composition.
  • the user takes the contact lens out of the composition and put the contact lenses on his/her eyes. More specifically, the ingredients of the composition absorb onto the surface of the contact lenses and then transfer into the user's eyes.
  • the composition according to the instant embodiment is intended for use in connection with soft and rigid contact lenses.
  • soft contact lens can refer to a hydrous soft contact lens made from hydrogels (i.e., hydrogel contact lenses) and a non-hydrous soft contact lens made from copolymers of butyl acrylate and butyl methacrylate.
  • the composition according to the instant embodiment is applicable to the soft contact lenses in U.S. FDA category Group I-IV.
  • Group I-IV lenses often contain materials identified in the market as: alphafilcon, asmofilcon, balafilcon, ethafilcon, hefilcon, hilafilcon, lidofilcon, lotrafilcon, methafilcon, nelfilcon, ocufilcon, omafilcon, phemfilcon, polymacon, tefilcon, tetrafilcon, vasurfilcon, vifilcon, senofilcon, galyfilcon, enfilcon, comfilcon, narafilcon, delefilcon, efrofilcon, and filicon II 3.
  • the composition according to the instant embodiment mainly includes a base solution, an algefacient, a surfactant, and a water soluble polymer.
  • the algefacient, the surfactant, and the water soluble polymer are uniformly dispersed in the base solution.
  • the base solution is a physiological saline solution with a buffer containing boric acid or phosphorous acid.
  • the buffer has a pH buffering capacity and is configured to adjust the pH of the composition to a pH between 6.8 and 7.6.
  • the base solution can include an appropriate amount of sodium chloride or potassium chloride to maintain the osmolality of the composition at a value between 250 Osmol/Kg and 350 Osmol/Kg.
  • the buffer can be selected from boric acid, borate (e.g., sodium tetraborate), phosphorous acid, or phosphate (e.g., sodium hydrogen phosphate and sodium dihydrogen phosphate). It should be noted that a buffer may be used alone or two or more different buffers may be used in combination in the base solution. In addition, the concentration of the buffer may be appropriately adjusted depending on its kind or the kind of the other ingredients.
  • the algefacient is added to reduce or relieve the discomfort and foreign matter sensation in the eyes and give the eyes a cool, fresh sensation.
  • the algefacient includes one or a combination of menthol, camphor, borneol, menthyl lactate, menthone glycerol ketal, monomethyl succinate, and p-menthane-3,8-diol.
  • the content of the algefacient is in the range between 0.001% (w/v) and 0.5 % (w/v), preferably between 0.001% (w/v) and 0.25 % (w/v), to avoid irritating the eye.
  • the surfactant is added to clean and moisturize a contact lens, in which protein and lipid deposits on the surfaces of the contact lens can be removed.
  • the surfactant is sodium lauroyl lactylate.
  • the content of the surfactant is in the range between 0.001% (w/v) and 2% (w/v), and preferably between 0.001% (w/v) and 0.5 % (w/v).
  • the expression of the algefacient in the composition for contact lenses can be performed effectively. Therefore, eye related symptoms such as eye fatigue, eye dryness, eye pruritus, and eye pain can be reduced or relieved, and a cool fresh sensation in the eyes can be maintained for a long period of time.
  • the water soluble polymer is added to moisten and lubricate the eyes, and also helps to keep the ingredients beneficial to the eyes in contact with the contact lens.
  • the composition for contact lenses includes one or more vitamins (e.g., A, B and E)
  • the vitamin(s) can be attached to the surface of the contact lens by interacting with the water soluble polymer.
  • the water soluble polymer includes PEG 400 and MPC in a molar ratio of 1:20.
  • the content of the water soluble polymer is in the range between 0.05% (w/v) and 5% (w/v).
  • Comparative Examples 1-5 and Comparative Examples 1-2 are shown in Table 1. Each of the compositions obtained respectively in Comparative Examples 1-5 and Comparative Examples 1-2 was used in full contact with the contact lenses. The contact lenses were then put on the user's eyes, and a VAS (Visual analogue scale) method was used to evaluate the sensations of lubrication, comfort, coolness, and moisture in the eyes during the period of initial wear (time 1) and after wearing for 30 minutes (time 2) and 60 minutes (time 3). The evaluation results of for the Comparative Examples 1-5 and the Comparative Examples 1-2 are shown in Table 2. Scores for each of the items, as shown in Table 2, are average scores calculated from three users (i.e., six eyes).
