Is Cataract Surgery Safe for Diabetic Patients?
Dr. Nikhil Nasta
2 min read
Diabetes is common - and cataracts often arrive earlier in diabetic patients. The question is not “if surgery is possible,” but whether inflammation and retinal risks are mitigated with good planning.
Modern phaco cataract surgery can be very safe in diabetics when blood sugar control and retina status are evaluated properly.
What surgeons worry about (specific, not scary)
Diabetic retinopathy (DR)
If DR is present - especially proliferative disease or diabetic macular oedema (DME) - your team may treat or stabilise retina issues before or around cataract planning.
Postoperative macular oedema risk
Diabetics have higher risk of cystoid macular oedema after cataract surgery in some profiles. Surgeons may use anti-inflammatory strategies tailored to risk.
Slower healing / infection vigilance
Poor control can affect healing. This is why teams ask for recent HbA1c and systemic medication lists.
What “good control” means in real life
There is no universal single cutoff published for every centre; many practices use HbA1c thresholds as guidance combined with clinical context (type 1 vs 2, swings, anaesthesia fitness). Be honest about readings - optimising glucose before elective timing often helps outcomes.
Biometry and lens choice
Diabetes can subtly affect measurements; repeat biometry may be requested if sugars were unstable. Premium IOL decisions should consider macula health and night vision needs.
