iDESIGN 2.0 Refractive Suite
1,257-point wavefront mapping that captures your eye's unique optical fingerprint. J&J Vision · FDA approved.
The Technology Behind Better LASIK Outcomes
Berg-Feinfield performs LASIK with four integrated FDA-approved platforms. Every step — from diagnostic mapping through laser treatment — is connected by design, producing outcomes that generic LASIK cannot match.
Advanced LASIK Technology at Berg-Feinfield
Four integrated, FDA-approved platforms carry your treatment from a 1,257-point diagnostic scan to bladeless flap creation and wavefront-guided laser reshaping — with zero blades used at any step.
iFS Advanced Femtosecond Laser
Bladeless flap creation with programmable depth, diameter, and hinge angle. J&J Vision · FDA approved.
STAR S4 IR Excimer Laser
ActiveTrak 3-D eye tracking and Variable Repetition Rate wavefront-guided treatment. J&J Vision · FDA approved.
Alcon WaveLight Pro
1,050 Hz 6-D eye tracking and a 1 kHz repetition rate — 20 to 50 seconds per eye. Alcon · FDA approved.
iDESIGN 2.0 Refractive Suite
The iDESIGN 2.0 Refractive Suite by Johnson & Johnson Vision is one of the most comprehensive diagnostic platforms available for LASIK in Los Angeles. In a single, non-invasive scan, it captures wavefront aberrometry, corneal topography, autorefraction, and keratometry all at once.
Its wavefront sensor maps 1,257 unique data points across your eye, capturing not just lower-order refractive errors — nearsightedness, farsightedness, and astigmatism — but also the higher-order aberrations that glasses and soft contacts cannot correct. These subtle imperfections contribute to halos, glare, and reduced contrast sensitivity. The data transfers directly to the excimer laser, creating a closed-loop process from scan to treatment.
- 1,257-point wavefront map per eye
- Wavefront, topography, autorefraction & keratometry in one scan
- Corrects lower- and higher-order aberrations
- Non-contact scan with direct laser integration
iFS Advanced Femtosecond Laser
The iFS uses ultrashort pulses of infrared laser energy to precisely separate corneal tissue at a programmed depth — with no blade involved at any stage. Unlike older microkeratome systems that used a mechanical blade, the iFS is entirely computer-guided.
Dr. Berg specifies flap depth, diameter, hinge position, and side-cut angle individually for each patient based on their corneal topography and anatomy. The result is a consistently precise flap with smooth, reproducible edges that repositions cleanly after treatment and heals predictably. The iFS integrates directly with iDESIGN 2.0 data, so the surgical plan flows continuously from mapping through flap creation to excimer treatment.
- Bladeless — no mechanical blade contacts the eye
- Programmable flap depth, diameter, hinge & angle
- Computer-guided design, customized per patient
- Integrates directly with the iDESIGN 2.0 surgical plan
STAR S4 IR Excimer Laser
The STAR S4 IR by Johnson & Johnson Vision performs the corneal reshaping step of LASIK. It is specifically validated to work with iDESIGN 2.0 treatment data — the diagnostic and treatment systems are designed as a matched pair.
ActiveTrak 3-D eye tracking monitors eye position continuously and compensates for movement in three dimensions, including cyclotorsion — rotational drift that is critical to precise astigmatism correction. If the eye moves outside the safe zone, the laser pauses instantly and resumes only when realigned. Variable Repetition Rate technology adjusts pulse frequency based on the tissue being treated, delivering energy efficiently and reducing treatment time for higher prescriptions.
- ActiveTrak 3-D eye tracking
- Cyclotorsion compensation for astigmatism
- Variable Repetition Rate treatment
- Validated with iDESIGN 2.0 wavefront data
Alcon WaveLight Pro Excimer Laser
The Alcon WaveLight Pro delivers laser corneal reshaping with a 1 kHz repetition rate and 1,050 Hz 6-dimensional eye tracking, compensating for movement in every direction, including cyclotorsion.
A faster laser means less corneal tissue exposure time. The WaveLight Pro typically completes treatment in 20 to 50 seconds per eye, compared with 60 seconds or more on older platforms. If the eye moves beyond a safe threshold, the laser pauses automatically and resumes only when repositioned. Combined with the iDESIGN 2.0 data pipeline, it executes each patient's wavefront-guided plan with sub-micron precision.
- 1 kHz repetition rate
- 1,050 Hz 6-D eye tracking
- 20–50 seconds of treatment per eye
- Sub-millisecond tracking response
How Technology Improves Precision and Safety
Not all LASIK is created equal. Diagnostic accuracy, laser precision, and system integration all shape your outcome — and every platform at Berg-Feinfield feeds directly into the next.
01
Diagnostic Precision
iDESIGN 2.0 captures 1,257 data points, including higher-order aberrations standard lenses cannot correct. The treatment plan is only as good as the data behind it.
02
Laser Accuracy
The WaveLight Pro tracks eye position at 1,050 Hz and adjusts delivery in real time, keeping every pulse precisely where it belongs as the eye moves.
03
Bladeless Safety
No mechanical blade contacts your eye at any point. Femtosecond flap creation reduces blade-related risk and gives the surgeon precise control over flap dimensions.
04
Visual Quality
Wavefront-guided treatment addresses higher-order aberrations — potentially improving contrast, reducing glare and halos, and delivering better night vision than conventional LASIK.

LASIK Technology Questions Answered
Berg-Feinfield uses four integrated FDA-approved platforms: the iDESIGN 2.0 Refractive Suite for diagnostic mapping, the iFS Advanced Femtosecond Laser for bladeless flap creation, and either the STAR S4 IR or Alcon WaveLight Pro excimer laser for corneal reshaping.
The iDESIGN 2.0 by Johnson & Johnson Vision maps 1,257 data points per eye in a single scan — capturing wavefront aberrometry, corneal topography, autorefraction, and keratometry simultaneously to build a fully custom LASIK treatment plan that corrects both standard refractive error and higher-order aberrations.
Bladeless LASIK means the corneal flap is created with the iFS Femtosecond Laser rather than a mechanical blade. The laser uses ultrashort infrared pulses at a precisely programmed depth, with fully customizable flap dimensions including depth, diameter, and hinge position. No blade contacts your eye at any point.
Wavefront-guided LASIK uses a 3D map of the eye's unique optical imperfections — including higher-order aberrations — to personalize the laser treatment beyond a standard glasses prescription. It can improve contrast sensitivity and night vision, and may reduce post-LASIK halos or glare compared with conventional LASIK.
The STAR S4 IR by Johnson & Johnson Vision features ActiveTrak 3-D eye tracking, Variable Repetition Rate technology, and cyclotorsion compensation. It is validated to work with iDESIGN 2.0 as a matched system — the diagnostic and treatment platforms are specifically designed to work together.
The Alcon WaveLight Pro has a 1 kHz repetition rate and 1,050 Hz 6-dimensional eye tracking. Treatment takes 20 to 50 seconds per eye depending on prescription. Its sub-millisecond tracking response compensates for eye movement in real time throughout the procedure.
Yes. All four platforms — iDESIGN 2.0, iFS Femtosecond Laser, STAR S4 IR, and Alcon WaveLight Pro — are FDA-approved for use in LASIK vision correction procedures.
Berg-Feinfield offers complimentary LASIK consultations at five Los Angeles locations — Burbank, Sherman Oaks, Beverly Hills, Arcadia, and Valencia. The evaluation includes iDESIGN 2.0 wavefront mapping, corneal thickness measurement, and a full candidacy review.
