Cataract Surgery in Kannur: What to Expect, Recovery, and How Diabetes Affects Outcomes
Cataract surgery is the most commonly performed operation in the world — and one of the most successful. Over 95% of patients achieve excellent vision improvement, and modern techniques have made the procedure faster, safer, and less stressful than ever. However, the decision to have surgery, the choice of lens, and the recovery process are all important — and people with diabetes need specific considerations. Our eye care team at MCR Diabetes & Eye Care, Kannur, walks you through everything.
A cataract is a clouding of the natural lens inside the eye, caused mainly by age but accelerated by diabetes, ultraviolet exposure, smoking, certain medications, and previous eye injuries. Once a cataract has developed, no medication or eye drops can reverse it — surgery is the only effective treatment. The good news is that surgery is quick, generally painless, and the visual results are usually dramatic. Our eye care service in Kannur offers comprehensive cataract care including pre-operative assessment, surgery referral, and post-operative follow-up.
What Is a Cataract?
The natural lens of the eye is normally clear, focusing light onto the retina. With age, proteins in the lens clump together, causing the lens to become cloudy. This is a cataract. Symptoms develop gradually over months to years and include:
- Cloudy, blurred, or dim vision
- Difficulty seeing at night
- Sensitivity to light and glare
- Halos around lights, especially at night
- Fading or yellowing of colours
- Frequent changes in glasses prescription
- Double vision in one eye
Key fact: Modern cataract surgery does not require waiting for the cataract to ‘mature’. Surgery is actually safer and easier on earlier cataracts. The decision is based on impact on daily life, not the appearance of the lens.
When Is Surgery Recommended?
The right time for cataract surgery is when the cataract is affecting your daily life — driving, reading, watching television, recognising faces, or working. There is no need to wait until the cataract is “mature” — modern surgery is actually easier and safer on earlier cataracts.
Common indications include:
- Difficulty driving, especially at night
- Trouble reading even with updated glasses
- Vision worse than 6/12 on the eye chart
- Glare from sun or headlights
- Significant difficulty with hobbies or work
- Need for clear vision for retinal examination (in diabetics)
The Cataract Surgery Procedure
Modern cataract surgery is called phacoemulsification. The procedure typically takes 15-20 minutes per eye and is done under topical (eye-drop) anaesthesia. You are awake but feel no pain.
Step-by-Step
- Pupil dilation — drops widen the pupil
- Anaesthesia — numbing drops; occasionally a small injection
- Small incision — about 2.2 mm at the edge of the cornea
- Removal of cloudy lens — ultrasound breaks up and aspirates the cataract
- IOL implantation — a folded artificial lens is placed in the empty lens capsule
- Wound seals naturally — usually no stitches needed
You go home the same day, usually within 1-2 hours of surgery completion.
Choosing Your Intraocular Lens (IOL)
The IOL is a permanent artificial lens implanted during surgery. Modern IOLs come in many designs, each with advantages.
The right IOL depends on your lifestyle, budget, eye anatomy, and presence of other eye conditions. People with significant diabetic retinopathy, macular degeneration, or other retinal issues are usually best served by monofocal lenses, as multifocal lenses can interact with retinal disease.
Special Considerations for Diabetics
Diabetes affects cataract surgery in several important ways:
Cataracts Develop Earlier
People with diabetes develop cataracts an average of 5-10 years earlier than non-diabetics. Cataracts in younger patients may progress faster as well.
Diabetic Retinopathy Must Be Assessed
Before surgery, the retina must be examined to detect retinopathy or macular oedema. If present, these may need treatment before or during cataract surgery to optimise outcomes.
Macular Oedema Risk
Cataract surgery can cause or worsen macular oedema in diabetic eyes. Pre-treatment with anti-inflammatory drops, or sometimes intravitreal injections, may be recommended.
Blood Sugar Control
Stable blood sugar before surgery is important. HbA1c below 8% reduces complications. Surgery is not delayed for minor blood sugar fluctuations, but uncontrolled diabetes increases infection and inflammation risk.
Slower Wound Healing
Diabetic eyes heal slightly slower, with marginally higher infection risk. Strict adherence to post-operative drops is essential.
⚠ Important: Severe eye pain, sudden vision loss, or significant redness after cataract surgery can indicate infection (endophthalmitis) — a sight-threatening emergency. Contact your surgeon immediately. Mild discomfort, fluctuating vision, and slight redness in the first few days are normal.
What to Expect Before, During, and After
Before Surgery
- Comprehensive eye examination 1-2 weeks before
- Measurements (biometry) to calculate IOL power
- Blood sugar and blood pressure optimisation
- Antibiotic eye drops starting 1-3 days before surgery
- Fasting may not be required (varies by surgeon)
- Arrange transport home — you cannot drive
Day of Surgery
- Arrival 1-2 hours before procedure
- Pupil dilation and pre-operative checks
- Surgery: 15-20 minutes
- Recovery: 30-60 minutes
- Home with an eye shield
Recovery Timeline
- Day 1: mild blurriness, gritty sensation; vision improving by evening
- Week 1: rapid improvement; antibiotic and anti-inflammatory drops 4 times daily
- Week 2-4: near-final vision achieved; drops continue but tapered
- Week 6: final glasses prescription if needed; full recovery
Restrictions During Recovery
- Wear eye shield at night for 1 week
- No rubbing the eye
- No swimming for 4 weeks
- No heavy lifting for 1 week
- Avoid dusty/smoky environments for 2 weeks
- Sunglasses outdoors for sun protection
Costs of Cataract Surgery in India
Costs vary widely depending on IOL choice and hospital. Approximate ranges in Kerala (2026):
- Monofocal IOL: ₹15,000 – ₹35,000 per eye
- Multifocal IOL: ₹50,000 – ₹1,20,000 per eye
- Trifocal/EDOF IOL: ₹70,000 – ₹1,50,000 per eye
- Toric add-on (for astigmatism): ₹15,000 – ₹40,000 additional
- Premium femtosecond laser surgery: ₹25,000 – ₹50,000 additional
Most insurance policies cover monofocal cataract surgery in full or with copayment. Premium IOLs are typically not covered.
Comprehensive Cataract Care
MCR Eye Care provides pre-operative assessment, IOL guidance, surgical referral, and post-operative care — especially important for diabetic patients.
Risks and Complications
Cataract surgery is very safe, but no surgery is risk-free. Possible complications include:
- Infection (under 0.1%)
- Posterior capsular rupture (1-2%)
- Retinal detachment (especially in high myopia)
- Macular oedema (more common in diabetics)
- Posterior capsular opacification (the “second cataract”) — easily treated with YAG laser
- Refractive surprise (vision not exactly as planned)

Frequently Asked Questions
Below are the questions our patients ask most often. If you have additional questions, our specialist team at MCR Diabetes & Eye Care, Kannur, is always available to help.
Can both eyes be operated on the same day?
Generally, surgeries are spaced 1-2 weeks apart to allow the first eye to settle and assess outcomes. Same-day bilateral surgery is done in select centres but is not the routine approach in India.
Will I need glasses after cataract surgery?
With monofocal IOLs, you typically need reading glasses (or distance glasses depending on lens choice). With multifocal, trifocal, or EDOF IOLs, most patients become glasses-independent for most activities.
Does diabetes increase surgery risks?
Slightly. Diabetes increases risks of macular oedema and slightly delays healing. With proper pre-operative assessment and post-operative monitoring, outcomes are still excellent. HbA1c below 8% before surgery is preferred.
Can the cataract come back?
The cataract itself cannot return — your natural lens has been replaced. However, the lens capsule (which holds the new lens) can become cloudy months to years later. This ‘posterior capsular opacification’ is easily treated with a brief YAG laser procedure.
Will my insurance cover cataract surgery?
Most health insurance policies cover monofocal cataract surgery (sometimes with copayment). Premium IOLs (multifocal, trifocal) are typically not covered and require out-of-pocket payment for the upgrade.
What if I wear contact lenses?
Soft contact lenses should be stopped 3-7 days before pre-operative measurements; hard/gas-permeable lenses earlier. This allows the cornea to return to its natural shape for accurate IOL calculation.
Can I have cataract surgery while pregnant?
Generally, elective cataract surgery is postponed until after delivery. Anaesthesia, drops, and antibiotics during pregnancy require careful consideration. Urgent surgery (rare) is performed when needed.
Final Takeaway: A Life-Changing Operation
Cataract surgery is, for most patients, life-changing. Colours return, reading becomes effortless, driving becomes safe again. The operation itself is brief, the recovery is quick, and the results are usually excellent — particularly when pre-operative assessment is thorough and post-operative care is strict.
