Xiidra, which I do not use after having poor results and may complaints from my patients about stinging, burning and not being
effective. If after a 9 months the person is still symptomatic on
restasis twice per day and preservative free artificial tears 2 to 4 times/day than I switch from restasis to Cequa, which is the same medicine as restasis (cyclosporine) but twice as concentrated and is said to penetrate deeper into the cornea. Cequa is more expensive.
