How WaveLight Plus InnovEyes Works: Step-by-Step Process Explained

Every WaveLight Plus InnovEyes journey at Centre for Lasik begins with a free Advanced Eye Mapping assessment. This session takes about 45–60 minutes. It’s painless and done without touching your eye. Using high-precision devices, the team captures:

• The detailed shape (topography) of your cornea
• Thickness maps across the entire cornea
• Your full spectacle power (not just the front surface)
• Measurement of internal eye optics, including the lens and posterior cornea
• Pupil size in different lighting conditions

For many patients—especially those with complex prescriptions or previous eye surgeries—this deeper profiling is crucial. Unlike basic LASIK pre-checks, InnovEyes looks at how light travels through your entire eye, not just the corneal surface. This session also screens for eligibility: if your cornea is too thin, you have progressive power changes, or any other medical reason, the surgeon will explain alternative options (such as PRK, ICL, or even non-laser treatments). If you’re considering laser in cities like Mumbai, Delhi, or Bangalore, the comprehensive mapping helps ensure you’re not missing underlying concerns. Read more about Advanced Eye Mapping.

After your scans, all measurements are combined into a Digital Eye Twin—a virtual 3D model unique to you. This is a key difference between WaveLight Plus InnovEyes and older LASIK or SMILE procedures.

• The surgeon and planning team use this model to simulate how light passes through every part of your eye.
• This lets them identify subtle imperfections and plan a truly personalized treatment—not just based on your glasses number, but on the way your eye bends light at every layer.
• The Digital Eye Twin also helps avoid over- or under-correction, and can take into account higher-order aberrations (tiny distortions responsible for issues like glare or halos).

This careful planning step typically takes about 20–30 minutes. It is not a one-size-fits-all approach; your plan is checked and approved by your surgeon. If you travel from outside your home city, you’ll receive a detailed briefing on the plan before surgery day. Want to compare this to standard LASIK workflows?

On the day of your procedure, you’ll meet your surgeon again for a pre-operative check. This includes verifying your measurements, reviewing your Digital Eye Twin plan, and confirming no changes in your health or vision since your mapping session.

• Eye drops are used to numb the eyes (no injections involved).
• The surgical team explains every step and answers any questions you have—especially if you’re concerned about comfort or have prior eye conditions.
• The laser suite at Centre for Lasik is kept at controlled temperature and humidity to optimise laser accuracy.

This pre-procedure phase generally takes 30–45 minutes, including paperwork and settling in. If you’re travelling from elsewhere in India, the team accommodates you with clear timelines. You’re also reminded that, while some patients may achieve better than 6/6 vision, individual results can vary and depend on your unique eye characteristics (see eligibility details).

The InnovEyes procedure is performed in two main parts: creating a protective flap, and reshaping your cornea with the excimer laser. The entire process for both eyes usually takes 15–20 minutes.

Femtosecond Flap Creation

• A femtosecond laser (not a blade) creates a thin corneal flap in about 10–20 seconds per eye.
• This precise, bladeless step helps speed recovery and minimises tissue disturbance.

Ray-Tracing Excimer Ablation

• Based on your Digital Eye Twin, the excimer laser applies a highly personalized correction, guided by ray tracing calculations.
• Only the necessary amount of tissue is removed—often about 15 µm per dioptre of correction, but this depends on your plan.
• The flap is gently repositioned at the end, no stitches required.

Throughout, you’ll be asked to look at a light target; most patients feel only slight pressure. You remain awake, but the team speaks with you at every step. The InnovEyes procedure steps focus on maximal individualisation, aiming to address subtle vision imperfections. However, as with all eye surgeries, there are risks of dryness, glare, or under/over-correction, which your surgeon will discuss in advance.

Right after the laser, you’ll rest for about 20–30 minutes in a recovery lounge. Your vision may be hazy or watery at first—this is normal. The surgeon examines your eyes under a slit lamp to ensure the flap is well positioned and the cornea is clear.

• Most Indian patients are discharged the same day—typically within 2–3 hours of arrival at the clinic.
• You’ll receive detailed instructions about eye drops, activity restrictions, and what to expect over the next 24–72 hours.
• Arrange for someone to accompany you home, as you should not drive immediately.

Follow-up care is included for 12 months. Your first check is usually the next day, then at 1 week, 1 month, and as advised. The Centre for Lasik team is available by phone or WhatsApp for questions. If you have a high-demand occupation (aviation, defence, police), check current official medical standards for laser surgery eligibility, as these rules can change (more info here).

Here’s a quick summary of the average time you’ll spend at each stage:

• Advanced Eye Mapping: 45–60 minutes (free assessment)
• Treatment Planning/Digital Eye Twin: 20–30 minutes
• Surgery Day (admission to discharge): 2–3 hours total, including preparation, procedure, and immediate recovery
• Actual Laser Procedure: 15–20 minutes for both eyes

Plan to take a day off from work or studies. Most patients rest at home the same evening and resume light activities the next day, but avoid strenuous work for a few days as advised. For those travelling from outside the city, the team can assist with local stay recommendations or remote follow-ups.
