Welcome to the Dermatology Expert Forum!
Majority of cases of cystic acne can be successfully treated with one 4-6 month course of isotretinoin (Accutane) at a dosage of 0.5-2.0 mg/kg body weight per day (approximately 40-160 mg per day in your case). Continued recovery and prolonged remission after discontinuation of therapy is expected, so it is not required to maintain treatment until total clearance is achieved. Progress you made should not be lost. However, in some, most severe cases, second course of therapy may be needed.
Isotretionin-induced blepharoconuctivitis (like yours) is frequently seen, and it is usually caused by bacteria Staphylococcus aureus. Artificial tears are recommended throughout the treatment with isotretionoin as first line of prevention of infection. Dry eyes and other eyes-related side effects rarely persist after discontinuation of therapy. Possibility of developing longer lasting ophthalmic (eye) problems has to be estimated by an ophthalmologist and will affect decision about further treatment with systemic retinoids.
FYI - Systemic retinoids (such as isotretinoin) should not be first line of acne therapy. Nowadays, we know way more about pathophysiology of acne and different therapeutic approaches are available. Treatment should be individualized and take patient's lifestyle (including nutritional habits, coping with stress, etc.) seriously into account.

By the way, when I say eye infection I am referring to styes in my upper eyelids. Are these common on accutane? From what I've read, a stye is bascially a blocked gland on your eyelid so is it basically your eye's version of a pimple?
I forgot to mention that the doctor wants me to go down to 40 mg and stay on that dose for another 2-3 months to try and acheive clearing because he said that he has been prescriping accutane for 25 years and he has never had ONE SINGLE patient that hasn't cleared but sometimes it takes longer than others.
