Hi Lec,
The scar you are referring to is called an infracillary incision. It is a surgical cut through the skin of the lower eyelid just below the eyelashes.
When these are well made, the scar rests up against the lower eyelid lashes and tends to fade in time. I am actually surprised to hear that your surgeon has prescribed this given that this scar tends to hide quite well against the eyelashes. In general, silicone gel is helpful and does speed up the healing of the scar. It is particularly helpful for raised or so-called hypertrophic scars.
There are two types of silicone gel used for this purpose. One is silicone gel sheeting. This material is very good for modifying young scars on the body where the sheeting can be worn under clothing almost continuously. The other form of these products is as a silicone gel ointment. The ointment is most helpful for locations where it might be too conspicuous to wear the sheeting. The sheeting will not work for the lower eyelid incision because of the mobility of this area. Be careful not to get the silicone gel ointment in the eye.
The good new is that this scar will fade in time with or without the silicone gel.
