Claim 14:
15. A method of increasing lipid layer thickness on a patient's eye in need of treatment, the method comprising the step of:
administering to an eye of the patient, an ophthalmic suspension comprising:
a) an ophthalmic suspension vehicle comprising:
i) an aqueous phase comprising water and one or more components selected from the group consisting of at least one wax ester, at least one anionic polar surfactant, at least one nonionic surfactant, at least one salt, and at least one phosphate; and
ii) an oil phase comprising at least one mineral oil and, optionally, at least one wax ester; and

b) at least one pharmaceutical ingredient,
wherein the ophthalmic suspension exhibits a zeta potential of from about −60 mV to about −110 mV and an ionic mobility of from about −5.9 (μm/s)/(V/cm) to about −7.4 (μm/s)/(V/cm).
