The present disclosure provides a solution for maintaining, by monitoring and guidance operations, a desired condition state in an eye of the subject, following an ophthalmological procedure. For example, the procedure may be corneal transplant, either a complete transplant of a corneal or a partial transplant of some layers of the cornea. Following the procedure, a gas bubble is injected into the eye to maintain the corneal graft in position. As long as the gas bubble is located below the corneal graft, it assists in maintaining the graft in position. As the gas bubble is lighter than the medium in the eye, it keeps pushing upwards and applying forces on the graft and preventing it from dislocating. The present disclosure provides a solution that keeps monitoring the gas bubble, or any other condition state resulted by an ophthalmological procedure and providing instructions to the subject in case the gas bubble deviates from certain allowed boundaries within the eye.
