Abstract

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).

Claims (22)

1. A method for improving comfortable wear time of a contact lens in an individual in need thereof, 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 comfortable wear time of the contact lens in the individual is increased relative to the comfortable wear time of the contact lens in 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 composition is administered to at least a portion of a palpebra conjunctiva of the eye of the individual.

3. The method of claim 2 , wherein the comfortable wear time of the contact lens is associated with an alteration to the palpebra conjunctiva, or a portion thereof.

4. The method of claim 3 , wherein the alteration to the palpebra conjunctiva comprises trauma or keratinization of the palpebra conjunctiva, or a portion thereof.

5. The method of claim 1 , wherein the composition is administered to an eyelid margin of the eye of the individual.

6. The method of claim 1 , wherein the method comprises treating inflammation, dryness, or pain associated with contact lens discomfort.

7. The method of claim 1 , wherein the method provides improvements in eyelid signs or tear film signs of contact lens discomfort (CLD).

8. The method of claim 1 , wherein the individual suffers from lid wiper epitheliopathy (LWE).

9. The method of claim 8 , 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.

10. The method of claim 9 , wherein the lid wiper epitheliopathy comprises trauma to the lid wiper region of the eyelid.

11. 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).

12. 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 carboxy late.

13. The method of claim 12 , wherein the at least one keratolytic agent is salicylic acid.

14. The method of claim 12 , wherein the at least one keratolytic agent is selenium disulfide.

15. The method of any one of claim 14 , wherein the concentration of the at least one keratolytic agent in the composition is between about 0.01% to about 10% by weight.

16. The method of claim 1 , wherein the individual has contact lens discomfort (CLD), or symptoms thereof.

17. The method of claim 16 , further comprising assessing the symptoms using a symptom scoring technique.

18. The method of claim 17 , wherein the symptom scoring technique is suitable for diagnosing contact lens discomfort (CLD), lid wiper epitheliopathy (LWE), eye dryness, eye pain, or eye inflammation.

19. The method of claim 18 , wherein the individual has been diagnosed with an ocular disorder using a contact lens dry eye questionnaire (CLDEQ) measurement tool.

20. The method of claim 19 , wherein the individual has a CLDEQ-8 score of at least 5.
