Compositions and methods for the treatment of contact lens discomfort
Described herein are compositions and methods for the treatment of contact lens discomfort (CLD) and/or lid wiper epitheliopathy (LWE). Such compositions comprise keratolytic agents, such as salicylic acid, selenium disulfide, or the like. Topical administration of such compositions to the inner surface of the eyelid provides therapeutic benefit to patients suffering from contact lens discomfort (CLD) and/or lid wiper epitheliopathy (LWE).
1. A method for improving vision in an individual wearing a contact lens, the method comprising:
(i) topically administering to an eye or an eyelid associated with the eye of the individual a pharmaceutically acceptable composition, the composition comprising a therapeutically-effective amount of at least one keratolytic agent and an ophthalmically-acceptable carrier; and
(ii) wearing a contact lens in the eye, wherein vision of the individual is improved relative to vision of the individual in the absence of the topical administration of the composition, and wherein the individual has not been diagnosed with meibomian gland dysfunction (MGD).
2. The method of claim 1 , wherein the individual is or has been assessed for comfortable wear time and/or subjective vision assessment prior to administration.
3. The method of claim 1 , wherein method provides improvement in comfortable wear time and/or subjective vision assessment.
4. The method of claim 3 , wherein the method provides improvement in subjective vision assessment.
5. The method of claim 1 , wherein the individual suffers from contact lens discomfort (CLD).
6. The method of claim 1 , wherein the individual suffers from lip wiper epitheliopathy (LWE).
7. The method of claim 6 , wherein the LWE comprises trauma to the lid wiper region of the eyelid.
8. The method of claim 1 , wherein the individual wears the contact lens one or more hour per day.
9. The method of claim 1 , wherein the composition is administered to an eyelid margin of the eye of the individual.
10. The method of claim 1 , wherein the eye of the individual comprises a lid wiper region and the pharmaceutical composition is directly administered to and/or reaches at least a portion of the lid wiper region following administration.
11. The method of claim 1 , wherein the at least one keratolytic agent is selected from the group consisting of benzoyl peroxide, coal tar, dithranol, salicylic acid, selenium disulfide, alpha-hydroxy acid, urea, lactic acid, sodium thioglycolate, zinc pyrithione, and zinc L-pyrrolidone carboxylate.
12. The method of claim 11 , wherein the at least one keratolytic agent is selenium disulfide.
13. The method of claim 1 , wherein the concentration of the at least one keratolytic agent in the composition is between about 0.01% to about 10% by weight.
14. The method of claim 1 , further comprising assessing a symptom related to the eye of the individual using a symptom scoring technique.
15. The method of claim 14 , wherein the symptom scoring technique is suitable for diagnosing CLD, LWE, eye dryness, eye pain, or eye inflammation.
16. The method of claim 15 , wherein the individual has been diagnosed with an ocular disorder using a contact lens dry eye questionnaire (CLDEQ) measurement tool.
17. The method of claim 16 , wherein the individual has a CLDEQ-8 score of at least 5.
18. The method of claim 1 , wherein the method comprises treating inflammation. dryness, or pain associated with wearing a contact lens.
19. The method of claim 1 , wherein the method provides improvements in eyelid signs or tear film signs of contact lens discomfort (CLD).
20. The method of claim 1 , wherein the method provides an improvement in horizontal (width) and/or sagittal (height) lesions and/or in lid parallel conjunctival folds (LIPCOF).
