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.
Not all LASIK is created equal. Diagnostic accuracy, laser precision, and system integration all shape your outcome.
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 cornea, capturing not just lower-order refractive errors (nearsightedness, farsightedness, astigmatism) but also 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. This is what makes wavefront-guided LASIK meaningfully different from conventional, one-size-fits-all protocols.
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, allowing the surgical plan to flow continuously from mapping through flap creation through excimer treatment — a coordinated workflow rather than disconnected steps.
The STAR S4 IR by Johnson & Johnson Vision performs the corneal reshaping step of LASIK in Los Angeles. 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), critical for precise astigmatism correction. If the eye moves outside the safe zone, the laser pauses instantly and resumes only when realigned.
Variable Repetition Rate (VRR) technology adjusts laser pulse frequency based on the tissue being treated — delivering energy more efficiently and reducing treatment time for higher prescriptions.
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 to 60 seconds or more on older platforms. If the eye moves beyond a safe threshold, the laser pauses automatically and resumes only when the eye is repositioned.
Combined with the iDESIGN 2.0 data pipeline, the WaveLight Pro executes each patient’s unique wavefront-guided treatment plan with sub-micron precision — laser energy applied exactly where it is needed, nowhere else.
Superior outcomes come from a coordinated system. At Berg-Feinfield, every platform feeds directly into the next.

| Conventional LASIK | Berg-Feinfield LASIK | |
|---|---|---|
| Flap Creation | Mechanical blade | ✓ iFS Femtosecond Laser — no blade |
| Diagnostics | Standard refraction | ✓ iDESIGN 2.0 — 1,257 wavefront points |
| Treatment | Glasses prescription only | ✓ Wavefront-guided — corrects HOAs |
| Eye Tracking | Basic or none | ✓ 1,050 Hz 6D tracking |
| Night Vision | May worsen halos/glare | ✓ HOA correction may improve quality |
| Treatment Speed | 60+ seconds per eye | ✓ 20–50 seconds per eye |
Dr. Alan M. Berg co-founded Berg-Feinfield and is one of the most experienced refractive surgeons in the Los Angeles area. He has performed tens of thousands of LASIK and refractive procedures — and trained other ophthalmologists who have gone on to lead practices across the country.
Dr. Berg was among the first surgeons in Southern California to adopt iDESIGN wavefront-guided LASIK, bladeless femtosecond flap creation, and the Glaukos iLink corneal cross-linking platform. As an FDA clinical study participant, he has contributed to the data shaping how these technologies are evaluated and approved.
Patients who are not right for LASIK are told so directly and offered the alternative that fits their eyes — whether that is PRK, EVO ICL, or another approach entirely. He sees LASIK patients at Burbank, Sherman Oaks, and Beverly Hills.
Berg-Feinfield performs iDESIGN 2.0 wavefront-guided LASIK across five Los Angeles area locations — Burbank, Sherman Oaks, Beverly Hills, Arcadia, and Valencia. Patients from Glendale, Pasadena, the San Fernando Valley, and throughout the greater LA metro are welcome.
Every patient begins with a complimentary LASIK evaluation at their preferred location — including wavefront mapping, corneal topography, and a full candidacy review before any treatment is scheduled. Request your evaluation here.
Your evaluation includes a full iDESIGN 2.0 wavefront scan, corneal thickness mapping, dry eye assessment, and prescription history review. If LASIK is the right fit, surgery is typically scheduled within a few weeks. If it is not, you will leave knowing exactly why — and what your options are.
Ideal candidates for LASIK in Los Angeles are adults 18 or older with a stable prescription, adequate corneal thickness, and healthy eyes. The iDESIGN 2.0 evaluation is the most reliable way to determine whether your corneal anatomy and optical profile make you a strong candidate.
Patients who don’t qualify for LASIK may be candidates for PRK or EVO ICL. Berg-Feinfield offers all three under one roof.
The cost depends on prescription complexity, technology used, and what is included. Berg-Feinfield provides transparent pricing including pre-operative evaluation, procedure, and post-op care. Financing is available. See the LASIK Cost Los Angeles page for details.
