It is good to know that the cornea has healed very well and that the vision is clear now.
Your detailed list of symptoms does point towards a possibility of blepharitis ( posterior blepharitis is where the meibomian glands get affected). As for the treatment of blepharitis is concerned, we had discussed it the last time we interacted. However I would like to send the remedies once again here-
First, application of heat to warm the eyelid gland secretions and to promote evacuation and cleansing of the secretory passages is essential. Individuals are directed to use soaked warm compresses and to apply them to the lids repeatedly. Warm water in a washcloth, soaked gauze pads, or microwaved, soaked cloths can be used. However extreme heat should be avoided.
•Second, the eyelid margin is scrubbed mechanically to remove adherent material, such as crusting, and to clean the gland orifices. This can be completed with a warm washcloth or with gauze pads. Water often is used, although some clinicians prefer that a few drops of baby shampoo be mixed in one bottle cap full of warm water to form a cleaning solution. Attention must be directed to gentle mechanical jostling or scrubbing of the eyelid margin itself, not the skin of the lids or of the bulbar conjunctival surface. Vigorous scrubbing should be avoided as it may be harmful.
•Third, an antibiotic ointment is applied to the eyelid margin after it has been soaked and scrubbed. Antibiotic-corticosteroid ointment combinations can be used for short courses, although their use is less appropriate for long-term management and should be used strictly on the advise of the ophthalmologist.
Anterior blepharitis is nothing but formation of scaly flakes all along the lid margin as seen in case of squamous blepharitis.
As for the possibility of demodex infection, very unlikely as it is caused by a rare crab louse ( which otherwise is seen in pubic area ). The only way to confirm is to get the eye examined by the ophthalmologist under the slit lamp ( equipment with magnification and focal light). But I guess you can just keep this possibility aside for the moment.
Please feel free to ask follow up questions if any.
