Cataract surgery for people with diabetes is safe and highly effective, and works just like standard cataract surgery — with extra attention to the retina. At our partner clinics it starts from £2,900 per eye for a monofocal lens, £3,796 for EDOF and £4,300 for multifocal, all-inclusive of consultation, biometry, retinal assessment, theatre, your lens and aftercare. Because diabetes can affect the retina, your consultant checks for retinopathy and macular oedema before surgery (often with an OCT scan), treats any active problem first, favours contrast-preserving monofocal or EDOF lenses, and monitors the macula closely afterwards.
Cataract surgery for patients with diabetes
Diabetes and cataracts often go together — cataracts tend to develop earlier and progress faster in people with diabetes. The good news is that cataract surgery is just as effective for diabetic patients; it simply needs more careful planning around the health of the retina. With the right assessment and lens choice, most people with diabetes achieve an excellent visual result.
The priority is the retina. Diabetes can cause diabetic retinopathy and macular oedema (swelling at the centre of vision), both of which are checked before surgery and monitored afterwards. Where these are present, we treat them first — for example with anti-VEGF injections for diabetic macular oedema or diabetic retinopathy laser treatment — so the eye is in its best condition.
Why diabetic eyes need extra care
- Faster-forming cataracts — often at a younger age
- Retinopathy risk — the retina is checked and treated if needed
- Macular oedema — slightly more likely after any eye surgery in diabetes
- Blood-sugar control — good control before and after improves healing
- Lens choice — tailored to protect contrast and night vision
Have diabetes and a developing cataract? A consultation includes a careful retinal check so your surgery is planned safely around your eye health.

Lens choice matters more when you have diabetes. Monofocal and EDOF lenses preserve contrast and are usually recommended; multifocal lenses may be avoided if there is retinopathy or macular oedema. Your consultant explains the safest option for your eyes.

What happens during the procedure
Before surgery, your consultant examines the retina (often with an OCT scan) so any diabetic changes are treated first. The cataract operation itself is the same safe, day-case procedure performed for all patients.
Surgery is performed under local anaesthetic eye drops — you stay awake but feel no pain, only mild pressure and light. Each eye takes 15 to 25 minutes, and you will be at the clinic for around 2 to 3 hours including pre-op checks and a short rest afterwards.
- Numbing drops are placed in your eye and the surrounding skin is cleaned with sterile solution.
- The surgeon makes a tiny 2.2–2.8mm incision at the edge of the cornea — small enough to self-seal without stitches.
- Phacoemulsification uses a fine ultrasound probe to gently break up and remove the cloudy lens.
- Your chosen intraocular lens (IOL) is folded, inserted through the same incision, and locked into place.
- The eye is shielded and you rest for 30–60 minutes before heading home.
Recovery week-by-week
Most patients notice clearer vision within hours, with full healing over about a month. For diabetic patients we keep a closer eye on the macula in the weeks after surgery.
Day of surgery
Vision is hazy for a few hours. Eye shield worn the first night. No driving or heavy lifting. Drops begin.
Days 1–3
Vision clears noticeably. Mild grittiness or watering is normal. Gentle activities and reading resume.
Week 1
First post-op review. Most patients are back to driving, working and walking — no swimming or eye-rubbing yet.
Weeks 2–4
Vision refines further. Drops continue. New glasses prescription (if needed) at week 4–6.
Beyond a month
Vision is settled. Second eye scheduled if both are being treated.
