Firstly i wana thanks all the Drs whoever responsed to my question. The double crease prob seems like improved slightly as i keep on doin lots of "open eyes exercise" bt i realized that is small dot of blue thread being exposed at the end. Issit this is the reason why my left eye unable to crease in nicely because the knot didnt burried deep enough? Will the thread become loose or what due to this? Do i need a revision as soon as possible or should i just wait? Thanks for all your advise.
