Small Incision Cataract Surgery (SICS): Procedure, Benefits, Recovery & Cost

Cataract is one of the most common age-related eye problems, caused by the clouding of the natural lens of the eye. Over time, this cloudiness blurs vision, makes everyday tasks difficult, and if left untreated, can even lead to blindness. Since cataracts cannot be treated with medicines or eye drops, cataract surgery remains the only effective solution.

Among the available surgical techniques, Small Incision Cataract Surgery (SICS) has become a popular choice worldwide. Known for being safe, stitch-less, and affordable, SICS cataract surgery restores vision with minimal complications.

In this article, let us explore what SICS eye operation is, how it is done, its advantages, recovery process, and cost.

What is Small Incision Cataract Surgery (SICS)?

SICS surgery is a modern cataract removal technique where the surgeon makes a very small incision, usually 5–7 mm, to remove the cloudy natural lens and replace it with an artificial intraocular lens (IOL).

Unlike older methods requiring larger cuts and stitches, SICS uses a self-sealing mini incision. This allows faster healing and reduced discomfort for the patient. Typically, patients stay overnight in the hospital and are discharged the next day after a follow-up check. Vision begins to return immediately after the SICS eye operation, improving steadily within a few days.

How SICS Surgery is Done?

The SICS cataract surgery procedure usually follows these steps:

1. Local anesthesia is given to numb the eye.
2. A small incision is created with a crescent blade.
3. The cataract-affected natural lens is removed manually.
4. An intraocular lens (IOL) is implanted in its place.
5. The eye is covered with a protective patch.
6. Patients usually stay overnight for observation.
7. The next day, the surgeon removes the patch, examines the eye, and provides protective dark glasses.
8. Post-operative instructions and medications are given for smooth recovery.

The actual surgical procedure takes about 10–12 minutes per eye, though the overall hospital process may take a few hours.

Benefits of Small Incision Cataract Surgery

SICS eye operation is preferred by many patients and doctors for several reasons:

• Affordable: Less costly compared to advanced techniques like Phaco.
• Painless & Stitch-less: No stitches required; self-sealing incision ensures quicker healing.
• Immediate Vision Restoration: Patients often notice clearer vision right after surgery.
• Quick Recovery: Healing generally takes 2–3 weeks, with most patients resuming daily life within a month.
• Safe for Mature Cataracts: SICS works well for thick and advanced cataracts where Phaco might not be suitable.
• Low Risk of Complications: When performed by skilled surgeons, results are excellent.

Types of Lenses Used in SICS

During SICS cataract surgery, the cloudy natural lens is replaced with an Intraocular Lens (IOL). The common options are:

• Monofocal IOLs– Provide clear vision at one distance (near or far).
• Multifocal IOLs– Restore vision at multiple distances.
• Toric IOLs– Correct astigmatism along with cataract removal.

The choice of lens depends on the patient’s eye condition, lifestyle needs, and affordability.

Recovery After SICS Cataract Operation

• Vision improvement begins immediately but stabilizes within a couple of weeks.
• Patients must avoid lifting heavy weights, bending, or rubbing the eye.
• Regular use of prescribed eye drops is essential.
• Protective glasses are advised to reduce light sensitivity and prevent dust entry.
• Follow-up checkups are critical to ensure smooth healing.

Most patients resume their routine activities after 3–4 weeks, once the eye is fully stabilized.

Does SICS Cataract Surgery Hurt?

No. SICS surgery is done under local anesthesia, which numbs the eye completely. Patients remain awake during the operation but do not feel pain—only mild pressure sensations.

After the surgery, mild irritation or watering may occur but severe pain is uncommon. With prescribed medications and drops, most patients experience a comfortable recovery.

SICS vs PHACO Cataract Surgery

• PHACO Surgery: Advanced, uses ultrasound to break the cataract before removing it. Less invasive but more expensive.
• SICS Surgery: Involves manual removal through a small incision. Affordable, effective for dense cataracts, but requires a slightly longer recovery.

The choice depends on the grade of cataract, patient’s budget, and the surgeon’s recommendation.

Cost of SICS Eye Operation

SICS cataract surgery is a cost-effective treatment option. In Bihar, India, the procedure with a standard monofocal lens can cost around ₹6,000–₹10,000, depending on the hospital, lens type, and facilities included.

This makes SICS an accessible solution for patients looking for safe cataract removal at an affordable cost.

Final Thoughts

Cataracts can severely affect quality of life, but modern treatments like Small Incision Cataract Surgery (SICS) restore vision safely and effectively. With its affordability, quick recovery, and reliable outcomes, SICS cataract surgery is a life-changing option for millions.

If you or a loved one is suffering from cataracts, consult an experienced eye surgeon to discuss whether SICS eye operation is the right choice.
