What is Customized LASIK Surgery?

Customized LASIK is an advanced laser eye surgery that treats your vision according to the unique imperfections of your eyes. In normal LASIK, patients receive a standard treatment based mainly on spectacle power. But in Customized LASIK, advanced eye scanning creates a detailed map of your eyes and helps the laser deliver highly personalized correction for better visual quality.

Every cornea has a slightly different shape - small bumps, dips, and curves that a basic prescription cannot capture. These irregularities cause issues like halos around lights at night, blurry vision in dim conditions, or a feeling that your vision is never quite sharp enough — even with glasses. Customized LASIK measures these surface variations and programs the laser to smooth and correct them as part of the treatment.

What We Measure Before Surgery and Why It Matters

Before a single drop is placed in your eye, your surgeon collects a set of measurements from your eyes. These are what make your treatment "customized." Here are the key parameters:

01

🗺️

CORNEAL TOPOGRAPHY

Think of this as a detailed photograph of your cornea's surface. The cornea is not perfectly smooth- it has tiny hills, valleys, and bumps unique to your eye. Topography captures this map in high detail so the laser can correct the shape of your specific cornea, not just your prescription number.

02

🔵

K-READINGS (CORNEAL CURVATURE)

K-readings measure how curved your cornea is steep like a basketball or flatter like a rugby ball. These measurements tell the surgeon how much power your cornea currently has, in which direction, and how to calculate the exact laser correction for your astigmatism. Every eye has different curvature, and the laser needs to know yours precisely.

03

📏

PACHYMETRY (CORNEAL THICKNESS)

Pachymetry measures how thick your cornea is in microns. This is the safety check. With a 130 microns flap and the planned laser ablation, the surgeon calculates whether enough corneal tissue will remain after surgery. The safe minimum is 250 microns of tissue left below the treated area. If there isn't enough, the treatment is modified or a different procedure is recommended.

04

👁️

PUPIL SIZE (MESOPIC)

Your pupil expands in the dark sometimes to 6mm or more. If the treatment area on the cornea is smaller than your pupil in low light, you'll see halos around headlights at night. This measurement is taken in a dim room to capture your pupil at its largest. The surgeon uses it to make sure the laser treatment covers the full pupil, protecting your night vision.

05

🔬

REFRACTION (YOUR GLASSES PRESCRIPTION)

This is your eye power- the sphere (near or far), cylinder (astigmatism), and axis (direction of astigmatism). Two versions are taken: one with your eyes working normally, and one after drops relax the focusing muscles completely. Both are cross-referenced with the topography data to finalize the exact correction targets for your surgery.

Before your workup: Remove soft contact lenses at least 5–7 days before your appointment. If you wear hard (RGP) lenses, remove them 2–4 weeks before. Contact lenses change the shape of your cornea — the topography must be taken when your cornea has returned to its natural shape, or the entire custom plan will be inaccurate.

How Customized LASIK Surgery Works

Here is step-by-step procedure of what happens to your eyes on the day of surgery:

1

Numbing Eye Drops

Anaesthetic drops are placed in your eye on surgery day. No injections, no pain. A small speculum gently holds your eyelids open.

2

130 Microns Flap Created

A precision microkeratome blade creates a 130-micron hinged flap on your cornea. Brief pressure is felt for a few seconds. The flap is gently folded back.

3

Custom Laser Fires

The excimer laser delivers your personalised ablation- correcting your prescription and smoothing the unique irregularities in your corneal surface simultaneously.

4

Flap Repositioned

The flap is carefully placed back. It adheres naturally within minutes - no stitches. The surgeon inspects the flap alignment before you leave the room.

On the day of Surgery: You will be in the clinic for approximately 2-3 hours in total, including preparation and post-procedure rest. The actual laser treatment per eye takes well under 2 minutes. All patients go home the same day and notice dramatically improved vision by the next morning.

Recovery Timeline After Customized LASIK

First 4–6 Hours

Rest at home- mild discomfort and watery eyes

Vision will be blurry. Avoid screens and bright light. Use prescribed eye drops. Sleep if possible as the eye heals rapidly during this time.

Day 1 (Next Morning)

Most patients see clearly enough to function

First post-op check confirms the flap is correctly positioned. Most patients can read and use screens comfortably. Driving may be possible after doctor's clearance.

Week 1

Return to desk work and daily activities

Avoid swimming, dusty environments, and eye makeup. Some fluctuation in vision day-to-day is completely normal during this week.

Week 2-3

Night vision improves as the cornea settles

Any remaining halos or glare from the healing cornea diminish during this period. Light exercise is fine. Contact sports are still avoided.

After Week 4

Final vision is fully stable

The complete benefit of the custom ablation is visible. Most patients reach their best-ever vision quality. Final prescription is confirmed at the 1 month check.

What to Avoid After C-LASIK

🚿

Swimming & Hot Tubs

Avoid it for at least 2–4 weeks after surgery.

🥊

Contact Sports

Avoid it for at least 4 weeks. Eye protection recommended.

💄

Eye Makeup

Wait at least 3-4 weeks before applying eye makeup.

✋

Rubbing Your Eyes

Never rub. The 130µm flap can be displaced. Critical for the first month.

Who Is Right for Customized LASIK Surgery?

Candidacy is determined by your workup measurements - particularly your corneal thickness, prescription, and topography. Here is a clear overview.

✓ You are likely a good candidate if you:

Are 18 years or older with a stable prescription for at least 6 Months
Are nearsighted (myopia), farsighted (hyperopia), or have astigmatism
Have corneas thick enough to safely allow a 130µm flap plus the planned laser ablation
Are generally in good health with no active autoimmune conditions

✗ Customized LASIK may NOT be suitable if you:

Have a prescription that is still changing year-to-year
Are pregnant or breastfeeding (hormonal changes affect corneal shape)
Have keratoconus or advanced corneal disease
Have certain autoimmune conditions (lupus, rheumatoid arthritis)
Have extremely thin corneas beyond the safe limit for SBK
Have severe, untreated glaucoma or cataract
Have a history of corneal scarring or irregular astigmatism
Are under 18 years of age

Risks and Side Effects of SBK LASIK

LOW RISK - COMMON & TEMPORARY

Temporary Dry Eye

Much less common with SBK than standard LASIK. Usually resolves within 3-6 months with prescribed lubricating drops.

LOW RISK - USUALLY TEMPORARY

Night Glare or Halos

Some patients notice halos around lights at night initially. Usually temporary.

RARE

Flap Complications

Buttonhole flaps or incomplete flaps are very rare in SBK. Incidence is far lower than with standard LASIK.

VERY RARE

Corneal Ectasia

This is a risk with all LASIK types but is significantly reduced with SBK because more residual stromal bed is preserved.

VERY RARE

Infections

The risk of infection is extremely low in accredited surgical centers. Antibiotic eye drops are prescribed pre and post-operatively to prevent it.

How Much Does Customized LASIK Cost?

The cost of Customized LASIK surgery depends on the technology used, surgeon experience, pre-operative evaluation, and hospital infrastructure. Since this procedure uses advanced personalized eye mapping technology, it usually costs more than standard LASIK surgery.

At Save Sight Centre, Delhi, the cost of Customized LASIK is ₹35,000 for both eyes. We are an NABH and ISO accredited eye hospital providing a cost-effective and reasonable investment for patients seeking freedom from glasses with high-quality technology and experienced eye surgeons like Dr. Rajeev Jain & Dr. Shuchi Gupta.

Frequently Asked Questions

01. How long is the recovery after Customized LASIK? ▼

Most patients notice a major improvement in vision within 24 hours and return to desk work and daily activities within 2–3 days. Full visual stabilisation, where the prescription is completely settled, typically happens within 3-4 weeks. Night vision often continues to improve during the first 4-6 weeks as the cornea heals and any mild halos from the healing process fade.

02. Can Customized LASIK give me better vision than glasses? ▼

Yes, it might be or might be not but it assures that your vision will be at least the same as with spectacles. It means your prescription power will be 0 after the surgery. Also, This is to inform you that LASIK corrects your current eye power and cannot stop your future prescription.

03. Is Customized LASIK painful? ▼

No. As numbing eye drops are used during surgery, patients usually feel only mild pressure for a few seconds. After the surgery, some patients may feel mild discomfort for a few hours but it would be better from the next day.

04. Is Customized LASIK safe? ▼

Yes. It is considered a safe and advanced procedure when performed after proper evaluation by an experienced eye surgeon. This is the safest surgery among all the surgeries of any other body part. As nothing goes inside, laser just reshapes the outer most layer of the eye which is cornea.

05. Can Customized LASIK improve night vision? ▼

Yes. Customized LASIK is specially designed to improve visual quality and reduce night glare and halos. You can choose it for specs removal plus a better vision quality.
