Steroid and antibiotic eye drops - hydrocortisone/neomycin/polymixin B; loteprednol/tobramycin; prednisolone/gentamycin; prednisolone/sulfacetamide; hydrocortisone /neomycin/bacitracin/ polymyxin B (Blephamide, Catapred [discontinued], Isopto, Pred-G, Poly-Pred [discontinued], Tobradex, Zylet and many other brands) are steroid and antibiotic eye drops prescribed to prevent or treat eye infections that are associated with inflammation. Side effects, drug interactions, dosage, and pregnancy safety information should be reviewed prior to using these medications.
You are exactly right in your thinking. Different drops are used to dilate eyes. Tropicamide (mydriacyl) is the most common drop and it comes in two strengths, % and %. The % will not last quite as long but it is not a large difference. Tropicamide will dilate the eyes and interfere with near focusing. Phenylephrine is often added as a second drop with mydriacyl to enhance the dilation. Phenylephrine enlarges and hastens the dilation but has no effect on focusing and usually does not prolong the dilation. Paremyd is another drop containing % hydroxyamphetamine and % tropicamide. It does not dilate the eyes as well but tends to last a shorter time period and not interfere with near focusing as much. Longer lasting drops include cyclopentolate and homatropine. They have a longer mode of action and exert significantly more interference with close vision. They are usually used for children.
Lotemax is used in dry eye syndrome to decrease and eliminate inflammation of the ocular surface caused by the hyperosmolarity of the tears. The inflammation must first be brought under control before any other treatments can be optimally effective. Lotemax would typically be prescribed for two weeks to three months initially and then may need to be used again on a 1-2 week regimen periodically if the inflammation occurs again. Lotemax ointment has become a choice of many doctors to treat inflammation caused by dry eye (ocular surface disease) because it can be used at night with a long contact period to the eye's surfaces and provide some functional lubrication while the eyes are closed.
