Design outcomes

Primary

Measure	Time frame
To compare these parameters in diabetic patients and non diabetic patients before and after cataract surgery using Optical Coherence Tomography Angiography-: a)Macular thickness b)Superficial capillary vessel density c)Superficial capillary plexus perfusion density d)Chorodial thickness e) Foveal avascular zone Timepoint: baseline before cataract surgery 7 days 1 month 3 months	—

Secondary

Measure	Time frame
1. To see correlation between macular thickness and superficial capillary plexus (SCP) vessel density that occurs due to cataract surgery. 2. To see correlation of macular thickness and superficial capillary plexus (SCP) vessel density with Best Corrected Visual Acuity. 3. To see correlation between foveal avascular zone and best corrected visual acuity. Timepoint: baseline before cataract surgery 7 days 1 month 3 months	—
