Formation Of Scar Tissue in Cornea.

Doctor, I Had Keratoconjunctivitis. Due To This, Small White Spots Developed in My Cornea. Doctor Told Me To Use A Lubricant Eye Gel Called "Hylo Gel" For The Spots. After Using The Drop Approximately 7-10 Months, My Doctors Told Me That Many Spots Are Faint Now. He Told Me To Continue The Gel And Also Told Me That The Spot Will Go Away But It Will Take Time. However, I Have Heared From A Doctor's Of Practo That The Spots Will Go Into Form Scar As Healing Process. Now, I Have Some Queries About This. 1) Is The Practo's Doctor Statement - "As A Healing Process, The Spots Will Go Into Forming Scar" Correct? 2) Is The Fainting/Disappearing/Healing Process  Of The Spots Will Form New Scar Tissue in My Cornea? 3) If The Spots Healing/Fainting/Disappearing Process Can't Form/Develop/Create New Scar Tissue in Cornea, Then Why Corneal Ulcer Healing Process Form/Develop/Create New Scar Tissue in Cornea? Please Answer All Of The Questions Doctor. Your Response is A Big Blessing For Me.
