Mytriacyl eye drops, which contain tropicamide ophthalmic solution USP 1.0% W/V, are used to dilate the pupil (mydriasis) and paralyze the eye's focusing muscles (cycloplegia). This is typically done before eye exams or certain eye procedures to help doctors visualize the eye more clearly. The medication is a sterile topical ophthalmic solution, and it should be administered by or under the direct supervision of a doctor.

Trypan blue ophthalmic solution is a dye used in ophthalmic surgery, primarily in cataract surgery, to stain the anterior lens capsule. This staining helps surgeons visualize the capsule more clearly, particularly when red reflex is poor or the pupil is constricted. It also improves the visibility of Descemet's membrane during surgery.
