A patient recently travelled from Bihar to Jaipur with a worrying combination: mature cataracts in both eyes and uncontrolled diabetes. She was anxious, and understandably so. Many patients assume diabetes means surgery isn’t an option. That’s not true.
At JEDH, we see cases like this regularly. The key is proper evaluation, blood sugar stabilisation, and then proceeding with a safe surgical plan.
What Happens When Cataract Becomes Mature?
A mature cataract means the lens has become completely opaque. Vision drops to hand-movement level or worse in many cases. The patient from Bihar could barely see from either eye before coming to us.
Mature cataracts are harder to remove than early-stage ones. The lens nucleus becomes dense and firm, which makes phacoemulsification more technically demanding. But it is still very much doable with the right equipment and surgical expertise.
The longer you wait, the harder the surgery becomes. The cataract can progress to a hypermature stage, increasing the risk of complications like lens-induced glaucoma. If you’re noticing worsening vision, don’t postpone your evaluation.
Can You Have Cataract Surgery with Uncontrolled Diabetes?
Uncontrolled diabetes raises surgical risks, but it doesn’t disqualify you from cataract surgery. Studies show that visual prognosis after cataract surgery in diabetic patients is generally favourable, with over 62% achieving good postoperative vision ([PMC, 2025](https://pmc.ncbi.nlm.nih.gov/articles/PMC12357705/)).
The process at JEDH typically looks like this:
Step 1: Stabilise blood sugar. We work with the patient to bring fasting sugar below 200 mg/dL before surgery. This isn’t always perfect, but we aim for the safest level achievable.
Step 2: Detailed retinal evaluation. Diabetic patients are at higher risk for diabetic retinopathy. We examine the retina thoroughly because retinal health directly affects visual outcomes after surgery.
Step 3: Phacoemulsification with appropriate IOL. We use the phaco technique (no stitches, no injection in most cases) with a foldable intraocular lens. The choice of lens depends on retinal health.
Step 4: Post-operative care and blood sugar monitoring. After surgery, blood sugar control remains critical for proper healing and infection prevention.
Why Did This Patient Travel from Bihar to Jaipur?
The patient shared that despite having diabetes, she wanted the best possible outcome. After seeing JEDH’s YouTube videos and reading about the hospital’s technology and results, she decided to travel over 1,000 km for her surgery.
She was nervous before the first eye. But after seeing the improvement in her vision, she confidently said, “I’ll get the second one done too.” Both eyes were operated successfully, and she was able to see clearly for the first time in years.
This isn’t unusual. We regularly treat patients from Bihar, Delhi, Madhya Pradesh, and other states who come specifically for advanced eye care at our Jaipur facility.
When Should Diabetic Patients Get Their Eyes Checked?
If you have diabetes, you should get a comprehensive eye exam at least once a year. Cataracts develop faster in diabetic patients compared to non-diabetic individuals. Diabetes also increases the risk of diabetic retinopathy, which can silently damage your retina without any symptoms in the early stages.
Watch for these warning signs: blurred vision that doesn’t improve with glasses, frequent changes in spectacle prescription, difficulty seeing at night, and sensitivity to glare. If you notice any of these, book an appointment without delay.
Frequently Asked Questions
What blood sugar level is safe for cataract surgery?
Most surgeons prefer fasting blood sugar below 200 mg/dL and HbA1c below 8.5% before proceeding. However, the decision depends on individual factors and how urgently the cataract needs to be removed.
Is cataract surgery riskier for diabetic patients?
Diabetic patients do face a slightly higher risk of post-operative inflammation, infection, and slower healing. But with proper pre-operative stabilisation and careful surgical technique, the success rate remains above 90%.
Can diabetes cause early cataract formation?
Yes. Diabetic patients tend to develop cataracts 5 to 10 years earlier than non-diabetic individuals. High blood sugar accelerates the clouding of the eye’s natural lens.
