Letter: Diagnose cloudy vision

I had a left trabeculectomy done in 2004 and was prescribed Latanoprost to control the pressure in my right eye.

Cataract surgery was carried out on my right eye in 2014 and a trabeculectomy was done in the right eye on June 29 2015. There is, however, one strange anomaly, in that when I wake up first thing in the morning my vision is clear cut and sharp but after 20 minutes it seems as if a cloud has descended which lasts all day.

I saw an optometrist who said he could not see any signs of corneal oedema of Fuch’s endothelial dystrophy. Have any optometrists reading this met a similar problem? Any solution would be appreciated.
