What is Contoura LASIK?
Contoura LASIK is an advanced, topography-guided laser vision correction procedure that maps the unique contours of the cornea for highly personalized treatment. It enhances visual quality by correcting even subtle irregularities, often providing sharper vision than standard LASIK.
Contoura LASIK in India
Conventional LASIK treats the number on your glasses prescription. Contoura LASIK treats the cornea itself. That is the simplest way to describe the difference. Contoura LASIK, also called topography-guided LASIK, uses a detailed map of thousands of individual points across the corneal surface to guide the excimer laser during treatment. Conventional LASIK mostly works off the refractive number (your sphere, cylinder, and axis), which is an average of the eye’s optics. Contoura LASIK adds a second layer: it maps the cornea’s individual quirks and irregularities and smooths them as part of the treatment, while also correcting the standard refractive error.
For most patients with ordinary corneas, conventional LASIK produces an excellent result. For patients with subtle corneal asymmetries, higher-order aberrations, or chronic complaints of glare and halos despite reasonable prescriptions, Contoura can offer a cleaner quality of vision. It is, arguably, the most personalised form of LASIK commercially available.
At Vasan Eye Care, Contoura LASIK is offered to selected patients whose corneal profile fits the technique, and who are seeking sharper quality of vision rather than just a lower prescription. The technique is supported by solid clinical evidence and is approved by regulatory bodies including the US FDA and the Central Drugs Standard Control Organisation in India.
Topography-guided LASIK has been available in India for several years and is now part of the refractive service offering at many tertiary ophthalmology centres. Indian patients increasingly seek Contoura LASIK for specific reasons: reducing night-time glare and halos, addressing higher-order aberrations, and achieving refined visual quality for activities where fine vision matters, such as night driving, screen work, sports, and professional roles that demand detail vision.
The workflow demands high-resolution corneal topography, usually captured on multiple occasions to confirm measurement stability. That data is then transferred to the excimer laser platform, which customises the ablation pattern for each individual eye. Candidate selection is strict: stable refractive error for at least one year, adequate corneal thickness, absence of keratoconus or other ectatic disease, and a healthy ocular surface. Skipping any of these is not a corner to cut.
Types of Contoura LASIK Platforms in India
Contoura Vision is the most well-known name, but several topography-guided platforms exist across Indian centres.
| Technique | Laser Platform | Key Feature | Typical Use |
|---|---|---|---|
| Contoura Vision (T-CAT) | Wavelight EX500 | Topography-guided with up to 22,000 data points | Myopia, hyperopia, astigmatism with corneal irregularities |
| Topolyzer-Guided LASIK | Wavelight platforms | Uses Placido disc topography data | Customised treatment of corneal surface |
| Schwind Amaris Topography-Guided | Schwind Amaris | Combines topography with aberrometry | Refined correction of irregular astigmatism |
| Zeiss CRS-Master Topography-Guided | MEL 90 | Integrates topographic and refractive data | Selected refractive corrections |
Contoura LASIK – How the Procedure Works?
Contoura LASIK follows the standard two-step LASIK approach, with sharper planning inputs. First, a thin corneal flap is created using either a femtosecond laser or a microkeratome. The flap is gently lifted to expose the underlying stromal tissue. Second, the excimer laser, programmed with the patient’s topography-guided plan, reshapes the stroma according to a bespoke ablation profile. The flap is repositioned and adheres naturally within minutes.
The difference from conventional LASIK lies in the precision of that ablation. By responding to the individual corneal map, Contoura can smooth subtle irregularities while also correcting the refractive error. Two patients with identical glasses prescriptions but different corneal shapes will get different Contoura treatments, because their corneas are genuinely different.
When Is Contoura LASIK Indicated?
Contoura LASIK is considered for patients who depend on glasses or contact lenses, have stable refractive error, and want to pursue laser vision correction. Topography-guided treatment may be particularly useful when:
- The patient reports significant glare, halos, or starbursts at night
- Topography shows subtle corneal surface irregularities
- The patient has tolerated contact lenses poorly
- The patient has occupational visual demands: night driving, precision work, aviation, sports
- Astigmatism is subtly asymmetric rather than cleanly regular
A thorough consultation is needed to confirm the eye is structurally suitable. Topography-guided treatment does not magically fix a fragile cornea, and it is not a workaround for keratoconus. The contraindications for Contoura are the same as for any LASIK: thin cornea, keratoconus, significant dry eye, unstable refraction.
Contoura LASIK – Step-by-Step Procedure
- Detailed refractive and corneal evaluation: topography, pachymetry, aberrometry, dry eye assessment.
- Treatment plan generated on the laser platform using topography data.
- On the day of surgery: topical anaesthetic drops instilled, eye prepared with antiseptic.
- Corneal flap created, typically with a femtosecond laser for bladeless flap creation.
- Flap lifted; topography-guided excimer laser ablation delivered, usually under a minute per eye.
- Flap repositioned and floated back into place.
- The patient rests briefly, receives post-operative drops, and is reviewed the next day.
How Much Does Contoura LASIK Cost in India?
Contoura LASIK is priced above conventional LASIK because of the added technology and planning. Indicative ranges:
| Variant | Indicative Cost Both Eyes (INR) | Typical Inclusions |
|---|---|---|
| Contoura Vision (T-CAT) | 90,000 to 1,50,000 | Pre-operative workup, surgery, post-op medications, follow-up visits |
| Topolyzer-Guided LASIK | 85,000 to 1,30,000 | Investigations, procedure, post-op care |
| Other Topography-Guided Platforms | 75,000 to 1,20,000 | Procedure and standard follow-up package |
Final pricing depends on the platform used, the hospital category, the city, and any additional investigations required.
Post-Surgery Care and Recovery
What to Expect After Contoura LASIK?
Most patients notice significant improvement in vision within a few hours, with continued refinement over the following days. Mild burning, watering, and light sensitivity are expected on the day of surgery and usually settle overnight. Night-time glare, if it was a pre-op complaint, usually reduces over the first few weeks as the cornea finishes healing. Visual stability is generally achieved within one to three months.
Post-Operative Care Tips
- Wear the protective shield at night for the first week.
- Use prescribed antibiotic and lubricating drops exactly as advised.
- Keep water out of the eyes for at least two weeks. No swimming for four weeks.
- Delay eye make-up for two weeks.
- Screen use can be uncomfortable initially because of reduced blink rate. Take frequent breaks and use lubricating drops generously.
- Wear sunglasses in bright sunlight.
- Attend review visits at day 1, week 1, month 1, and month 3.

Frequently Asked Questions
Standard LASIK primarily treats the refractive error. Contoura LASIK uses a detailed map of the corneal surface to guide the laser, which allows correction of subtle corneal irregularities on top of the standard myopia, hyperopia, or astigmatism. Same procedure, sharper plan.
Suitability depends on refractive stability, corneal thickness, topographic pattern, tear film health, and the overall condition of the eye. Some corneas are better candidates for SMILE or PRK instead. The only way to know is a thorough pre-operative evaluation.
No. The procedure is performed under topical anaesthesia. Most patients describe pressure or mild awareness during the laser step, but not pain. Discomfort in the hours after surgery (grittiness, watering, light sensitivity) is normal and usually settles by the next morning.
The laser treatment itself takes less than a minute per eye. The entire surgical visit, including preparation and post-op observation, runs about one to two hours.
Office and desk-based work can generally resume within two to three days. Jobs involving dust, physical exertion, or outdoor environments may need up to a week off.
Most patients achieve very good uncorrected vision, and many describe better quality of vision than they had with their pre-op glasses or contact lenses. Individual results vary with starting prescription, corneal characteristics, and the fit between the technology and the eye. Perfect is too strong a word; excellent is realistic for most well-selected candidates.
The corneal reshaping is permanent. The cornea does not regrow. What can change later is unrelated: presbyopia appears in the mid-40s and reading glasses may enter your life anyway, and cataracts can develop as you age. These are not failures of the LASIK.
Most patients can drive within two to three days, once the surgeon confirms adequate visual acuity and comfort. Night driving sometimes takes a little longer as the eye settles.
Many patients report a real reduction in night-time visual disturbances after Contoura LASIK, especially when the pre-op cornea showed irregularities that were contributing to those symptoms. It is one of the strongest reasons to choose Contoura over standard LASIK for the right eye.
The procedure is generally performed on adults between 18 and 45, with stable refraction for at least a year. Older patients can be considered after careful assessment, though refractive lens exchange or cataract-based solutions may be more appropriate past a certain age, especially once early lens changes are visible.
