Prescription leeway for monofocal iols and laser adjustment

After my cataract op last October my left eye has come out: Sphere: +0.5, Cylinder -0.75 x 10.  I am wondering whether a laser adjustment could reduce the prescription to 0 or -0.5, and whether it could also cure the astigmatism.  But first need to know the margin of error to see whether such an adjustment might take the prescription down further.  I think the surgeon and the optician both consider I am chasing perfection and that the adjustment would be best made by glasses - and I don't mind wearing them !

NB My original prescription was -15 sphere, and I think this may affect the degree of accuracy or a laser adjustment.

    I am seeing the surgeon in a couple of weeks:  I will request 0 to -0.25 spherical correction in the right eye and discuss with him if aiming at 0 cylinder is feasible.  (The current cylinder is 0.75 x 172 6/6+).  If an astigmatism correction is not available on the UK NHS it is probably worth paying the extra cost.    I did wonder whether I should have requested near vision in both eyes as most of my work is at close range and I was previously very myopic, but I think monovision iols would still have been very fixed focus, and so (eg) only set (at a distance decided by the surgeon), probably for reading, and not other activities such as playing the piano or organ(armslength), laptop, teaching, shopping, reading the car satnav etc.  

    So I would have been just as dependent on progressive glasses or mini-monovision glasses as I am/will be with the iols set on distance ?

      Just spotted a typo - last sentence should have read: So would I have been just as dependent on progressive glasses or mini-monovision glasses as I am/will be with the iols set on distance ?
