Check list for calculating risk of cataract surgery, adults (phaco), PS | |||
age above 85 higher risk | PXF.... loose zonules | ||
dm...? acular drops/CSME risk | previous vitrectomy | ||
lives alone..?overnight stay | dm maculopathy/pre-prolif | ||
warfarin, must have (eg new valve) | INR </=3.0 | cannot lie still GA, with head back otherwise high risk | |
warfarin, if not vital stop 3d before | macula soft drusen (may deteriorate after surgery) | ||
marked blepharospasm consider GA, otherwise high risk |
refraction anisometropia/myopic surprise/patient aware/patient wants | ||
nasolacrimal duct obstruction with previous dacrocystitis DCR first | high BP ideal <150 systolic BP related to CME risk, especially if diabetic |
||
general health poor for age, etc | obesity | ||
problems other eye | anxious | ||
only eye | glaucoma pressure spike/rise postop control before hand | ||
mature / anterior cortical require vision blue (used in other cases too eg shallow AC, any poor view) | blepharitis/ dry eyes markedtreat first (with blepharitis Rx) eg 3 months /atopic conjuncitivitis | ||
enothelium fuchs (=post op corneal oedema) axial length <22.0 (<22.5) . | Consent include... multiple operations, high pressure, infection, bleeding, loss of vision, loss of eye | ||
anterior chamber shallow...difficult surgery.......... | deep set eyes surgery far more difficult | ||
can lie flat...breathing OK | any current investigations/current health problems | ||
tamulosin...flomax | small pupil or similar ocular problem | ||
anterior chamber deep..loose zonules > 27.0 (26.5) | previous trabeculectomy.......may fail |
