Patent Claims:	1. An ophthalmic composition comprising CF3—(CF2)3—CH(CH3)—(CH2)2—CH3 and CF3—(CF2)3—(CH2)4—CH3. 2. The composition according to claim 1, wherein the composition consists of the CF3—(CF2)3—CH(CH3)—(CH2)2—CH3 and the CF3—(CF2)3—(CH2)4—CH3. 3. The composition according to claim 1, being in liquid form and comprising at least 1 wt % of said compound CF3—(CF2)3—CH(CH3)—(CH2)2—CH3 or from 1 wt % to 5 wt % of said compound CF3—(CF2)3—CH(CH3)—(CH2)2—CH3, based on the total weight of the composition. 4. The composition according to claim 1, being formulated as a clear liquid solution. 5. The composition according to claim 1 being substantially free of: (a) a polymer, (b) a perfluorinated compound, and/or (c) a dissolved pharmacologically active ingredient which is not a semifluorinated alkane. 6. The composition of according to claim 1, wherein the composition is in liquid form and consists essentially of the compound CF3—(CF2)3—CH(CH3)—(CH2)2—CH3 in an amount from 1 wt % to 5 wt % and the compound CF3—(CF2)3—(CH2)4—CH3 in an amount up to 95 wt %, based on the total weight of the composition. 7. The composition according to claim 1, being in liquid form and comprising from 1 wt % to 5 wt % of CF3—(CF2)3—CH(CH3)—(CH2)2—CH3 and up to 95 wt % of CF3—(CF2)3—(CH2)4—CH3, based on the total weight of the composition. 8. The composition according to claim 7, being formulated as a clear liquid solution. 9. The composition according to claim 8 being substantially free of: (a) a polymer, (b) a perfluorinated compound, and/or (c) a dissolved pharmacologically active ingredient which is not a semifluorinated alkane. 10. The composition of according to claim 9, wherein the composition consists essentially of the CF3—(CF2)3—CH(CH3)—(CH2)2—CH3 and the CF3—(CF2)3—(CH2)4—CH3, and optionally one or more lipophilic liquid constituents. 11. A kit comprising an ophthalmic composition according to claim 1 and a container for holding the composition, wherein said container comprises a dropper which dispenses droplets having a volume of 8 to 15 μL topically to a lacrimal sac, lower eyelid, eye surface, or other ophthalmic tissue. 12. A method of treating a disease or condition of a patient in need of such treatment, comprising administering the composition according to claim 1 to the patient. 13. The method according to claim 12, wherein the disease or condition is dry eye disease (keratoconjunctivitis sicca) or a symptom or condition associated therewith; and/or Meibomian Gland Dysfunction (MGD), or a symptom or condition associated therewith. 14. The method according to claim 13, wherein the composition is topically administered into the lacrimal sac, into the lower eyelid, to an eye surface or to an ophthalmic tissue. 15. The method according to claim 12, wherein the disease or condition is corneal damage. 16. A method of treating a disease or condition of a patient in need of such treatment, comprising administering the composition according to claim 10 to the patient. 17. The method according to claim 16, wherein the disease or condition is dry eye disease (keratoconjunctivitis sicca) or a symptom or condition associated therewith; and/or Meibomian Gland Dysfunction (MGD), or a symptom or condition associated therewith. 18. The method according to claim 16, wherein the disease or condition is corneal damage.
