Ophthalmological surgery colorant and delivery system
View Patent ↗Improved ophthalmological surgical methods, systems and devices, employing a colorant.
1. A method for providing an indocyanine green colorant for ophthalmological surgery, comprising the steps of:
a. providing an indocyanine green colorant in a first chamber;
b. providing an aqueous diluent for the indocyanine green colorant in a second chamber;
c. providing a third chamber, external of both the first and second chambers, for mixing the indocyanine green colorant with the aqueous diluent to form an admixture;
d. mixing the indocyanine green colorant with the aqueous diluent in said third chamber to form the admixture; and
e. administering the admixture into a patient.
2. The method of claim 1 , wherein the patient is a cataract surgery patient.
3. The method of claim 1 , wherein the indocyanine green and diluent are admixed in a proportion ranging from about 1 to about 4 mg colorant to about 0.5 ml diluent.
4. The method of claim 1 further comprising performing a peel of an internal limiting membrane of the eye.
5. The method of claim 1 , wherein the colorant has an osmolarity that ranges from about 200 to about 325 mOsm.
6. The method of claim 1 , further comprising including in the admixture an antibiotic.
7. The method of claim 1 , wherein the admixture is prepared prior to the step of administering to the patient.
8. The method of claim 1 , wherein the admixture is prepared during the step of administering to the patient.
9. The method of claim 1 , further comprising providing a conduit having a bore of about 20 to about 40 gauge for directing the admixture during the step of administering.
10. The method of claim 4 , wherein the colorant has an osmolarity that ranges from about 200 to about 325 mOsm.
11. The method of claim 4 , further comprising including in the admixture an antibiotic.
12. The method of claim 4 , wherein the admixture is prepared prior to the step of administering to the patient.
13. The method of claim 4 , wherein the admixture is prepared during the step of administering to the patient.
14. The method of claim 4 , further comprising providing a conduit having a bore of about 20 to about 40 gauge for directing the admixture during the step of administering.
15. The method of claim 1 , further comprising staining an internal limiting membrane of a patient, but not the underlying retina, and performing a peel of the internal limiting membrane.
16. The method of claim 15 , further comprising including an antibiotic in the admixture.
17. The method of claim 15 , wherein the admixture is prepared during the step of administering to the patient.
18. The method of claim 15 , wherein the administering step includes administering the admixture through a conduit having an open end.
19. The method of claim 1 further comprising steps of:
staining an internal limiting membrane of a patient, but not the underlying retina; performing a peel of an internal limiting membrane of the eye;
including in the admixture an antibiotic; and
wherein the administering step includes administering the admixture through a conduit having an open end.
