You are right, the predominant symptom in case of posterior capsule opacification (PCO) after cataract surgery is blurring of vision. But rarely, some patients might present with initial symptoms of haloes followed by blurring of vision. If your Ophthalmologist has evaluated you after pupillary dilatation, then he must have seen formation of PCO requiring capsulotomy with YAG (creating a hole in the posterior capsule).
The other possibility is increased intraocular pressure or glaucoma. This usually presents as seeing colored haloes against light. In case you have a angle closure glaucoma, then a laser iridotomy (creating a hole in the iris) by YAG laser is done to relive the pressure. So, it might be possible that your doctor is planning iridotomy. YAG laser is used both for creating a hole in capsule in case of PCO and a hole in iris in case of glaucoma.
you have most probably got toric intraocular lenses (IOL) implanted in your eyes. If after surgery, you had no problem and the vision was good, then mostly after YAG, your vision should return back and the haloes should also go.
You are experiencing haloes because of PCO forming and in addition Toric IOL was implanted in your eye.
Usually the PCO does not form after days of surgery. It takes a few days to a few years, unless there is an inflammatory condition going on in the eye. When was the surgery done and since when are you having glare?
If your vision was good after the surgery, but you had the glare problem from the very beginning, then most probably the axis of the Toric IOL needs to be adjusted a little. A few patient's eyes are more sensitive than usual. A minor 3-5 degree shift in the Toric IOL (which can occur occasionally), might bring uncomfortableness and symptoms like yours. So, if you are having blurring of vision also then initial step should be to perform YAG capsulotomy. If after the capsulotomy the haloes still persist, then the adjustment of the IOL can be tried. Till that time I would advise you to abstain from self driving at night.
