Laser Cataract Surgery (FLACS) vs Traditional Phacoemulsification
Dr. Nikhil Nasta
2 min read
Phacoemulsification (“phaco”) is the standard ultrasound-based technique to remove a cataract through a small incision. Femtosecond laser-assisted cataract surgery (FLACS) adds a laser platform to automate certain steps (e.g., capsulotomy, lens fragmentation patterns - depending on surgeon protocol and device).
Patients understandably assume laser = newer = better. The more accurate framing from large trials and reviews: final vision outcomes are often similar for many straightforward cases, while cost is higher with FLACS and benefits may be situational.
What FLACS can offer (in selected eyes)
Potential advantages discussed in literature and surgical teaching include:
- Highly precise circular capsulotomy (relevant for premium IOL centration goals)
- Patterned lens fragmentation that may reduce ultrasound energy in some cases
- Arcuate incision planning for astigmatism management when used as part of a plan
None of this guarantees a better result for every patient - surgeon skill and biometry accuracy remain central.
What phaco already does extremely well
Modern phaco with experienced surgeons delivers excellent safety and visual outcomes across millions of cases yearly in India. For many patients, phaco + a well-chosen IOL is the value sweet spot.
Evidence snapshot (how to think, not a promise)
Multiple randomised studies and meta-analyses find no durable superiority for FLACS over phaco for many standard outcome measures; some early postoperative differences can normalise over follow-up. Complication profiles are broadly low for both, with nuance depending on case complexity and centre volume.
Takeaway: choose FLACS because your surgeon explains a patient-specific reason, not because of generic advertising.
Cost and insurance
FLACS is commonly an add-on fee; insurance may not cover it beyond a basic package. Ask for itemised pricing for: laser fee, IOL, facility, and follow-ups.
