Ophthalmologic irrigation solutions and method
View Patent ↗Solutions for perioperative intraocular application by continuous irrigation during ophthalmologic procedures are provided. These solutions include multiple agents that act to inhibit inflammation, inhibit pain, effect mydriasis (dilation of the pupil), and/or decrease intraocular pressure, wherein the multiple agents are selected to target multiple molecular targets to achieve multiple differing physiologic functions, and are included in dilute concentrations in a balanced salt solution carrier.
1. A method for promoting mydriasis during an intraocular ophthalmologic procedure, comprising intraocular application of a solution comprising a local anesthetic agent combined with a mydriatic agent that is an alpha-1 adrenergic receptor agonist in a physiologic carrier, wherein the agents are included in therapeutically effective amounts for mydriasis during the procedure when delivered intraocularly.
2. The method of claim 1 , wherein the local anesthetic agent is selected from the group consisting of lidocaine, tetracaine, bupivacaine, and proparacaine.
3. The method of claim 1 , wherein the alpha-1 adrenergic receptor agonist is selected from the group consisting of phenylephrine, epinephrine and oxymetazoline.
4. The method of claim 1 , wherein the alpha-1 adrenergic receptor agonist is selected from the group consisting of phenylephrine and epinephrine.
5. The method of claim 4 , wherein the local anesthetic agent is selected from the group consisting of lidocaine, tetracaine, bupivacaine, and proparacaine.
6. The method of claim 1 , wherein the solution is applied in a liquid irrigation carrier.
7. The method of claim 6 , wherein the solution is applied by intraocular irrigation.
8. The method of claim 6 , wherein the liquid irrigation carrier further comprises electrolytes sufficient to provide a physiological balanced salt solution.
9. The method of claim 1 , wherein the solution is continuously applied to the intraocular tissues during the intraocular procedure.
10. The method of claim 1 , wherein the solution further comprises a non-steroidal anti-inflammatory drug (NSAID).
11. The method of claim 1 , wherein the alpha-1 adrenergic receptor agonist is included in the solution at a concentration of no more than 1,000,000 nanomolar and the local anesthetic agent is included in the solution at a concentration of no more than 100,000,000 nanomolar.
