Query About Sub-Epithelial Infiltrates.

Doc, I Was Reported in Practo That I Had Viral Keratoconjunctivitis And Due To This, I Had Small White Spots in My Left Eye's Cornea. My Vision is 6/6p With Glasses in Left Eye. My Lefr Eye's Vision is Blurry Than Right Eye. So, One Of The Practo's Doctor Told Me That The Small White Spots (May be Called As Sub-Epithelial Infiltrates) Leaves Scar in Some Cases. Now, My Query is: 1) Does The Small White Spots Leave Scar in All Cases? 2) Can Any Eye Doctor Will Be Able To Detect If The Small White Spots Leave Scar in Cornea? 3) Can The Small White Spots Cause Blurry Vision? If The Answer Is Yes, Then Let Me Know That If The Spot Go Away, Will The Blurry Vision Also Resolved? Please Answer This Questions, Doc.
