Purpose
To study the effect of Phacoemulsification using a physiological intraocular pressure(IOP)and high IOP on the retinal and optic nerve head(ONH)perfusion.
Setting
Iladevi Cataract & IOL Research centre, & Raghudeep Eye Hospital, Ahmedabad, India
Methods
Prospective,Randomized,single masked Clinical Trial in 80 eyes(80 patients)with non-proliferative diabetic retinopathy undergoing cataract surgery.Eyes undergoing cataract surgery will be randomized to:group I(low IOP,20mmHg)or group II(high IOP, 55mmHg).Intraoperatively, cumulative dissipated energy (CDE),fluid used and patient comfort on visual analog scale.Retinal vessel density,Perfusion density at superficial retinal layers at the posterior pole as well as perfusion and flux index at the RPC layer was documented by optical coherence tomography angiography(OCTA)at the following time points:within 2 hours of surgery,1 day and 1 month postoperatively.Anterior chamber inflammation compared on postoperative day 1 and week 1.
