Topical Mydriasis
Intracameral Mydriasis
Topical + Intracameral mydriasis
Topical mydriasis will be with 1 drop of phenylephrine 2.5% and 1 drop of cyclopentolate 1% x 4 doses each, with each drop spaced 5 minutes apart given in the pre-op area. These are the standard dilating drops used for cataract surgery. These patients will also receive intracameral lidocaine 1% for anesthesia.
Intracameral mydriasis will be with 0.2ml to 0.3ml of epinephrine 1:10,000 injected into the anterior chamber at the beginning of the cataract surgery procedure. This is the standard concentration use for intracameral mydriasis in cataract surgery. These patients will also receive intracameral lidocaine 1% for anesthesia.
