Query About 6/6p Vision. It good sign?

Doctor, I Had Keratoconjunctivitis. Due To It, I Had Small White Spots in My Left Eye's Cornea. I Can Feel That My LE's Vision is Blurry Than RE. My Doctor Also Told Me That The Spots Will Effect My Vision. Doctor Told Me To Use A Lubricant Eye Gel Called "Hylo Gel". I Have Previously Used The Gel Continuously For 5-7 Months And Then I Discontinued The Drop Without Doctor's Consult. I Re-Started The Drop Again After 1-2 Months. After Re-Starting, I Used The Gel For 3-4 Months. I Was Consulted A Doctor in The Day Before Yesterday And The Doctor Told Me That Most Of The Spots Are Faint. Doctor Told Me To Continue The Drop And He Also Told Me That The Spots Will Go But It Will Take Time. However, When I Opened My Eye's Prescriptions, It Show That My Visual Acuity is 6/6 With Glasses in Right Eye And 6/6p in Left Eye. Now, My Query is: 1) What Does 6/6p Vision? 2) Will The Spots Go Away? 3) Why My Doc Wanted To Mean by Saying That Most Of The Spots Are Faint? Is It Good Sign?Pls Ans, Doc.
