FEMTOSECOND LASER-ASSISTED CATARACT SURGERY (FLACS)

Femtosecond Laser-Assisted Cataract Surgery, also called FLACS, is an advanced method of cataract removal that uses computer-guided laser technology to perform key steps of surgery with high precision. Instead of relying only on handheld instruments, the surgeon uses a femtosecond laser to create corneal incisions, open the lens capsule, and soften the cloudy lens. As a result, the procedure becomes more accurate, reproducible, and customized for each eye.

HOW FLACS WORKS

First, detailed three-dimensional scans of the eye are captured. Then the laser uses these images to map and treat the exact surgical area. Next, the laser creates precise micro-incisions and a circular opening in the lens capsule. It also pre-fragments the cataract into smaller pieces. Because of this step, less ultrasound energy is often needed during lens removal. The surgeon then completes the procedure and implants the selected intraocular lens.

KEY BENEFITS

FLACS offers several potential advantages when compared with conventional cataract surgery. However, suitability still depends on individual eye findings and clinical goals.

1. Greater precision in corneal incisions and lens capsule opening.
2. Improved centration and sizing for premium lens implants.
3. Reduced ultrasound energy in many cases.
4. Better astigmatism management with laser-created arcuate incisions.
5. High level of customization based on eye imaging data.

WHO MAY BENEFIT MOST

FLACS is often helpful for patients who choose premium intraocular lenses, such as toric or extended depth of focus lenses. In addition, patients with corneal astigmatism may benefit from laser-assisted astigmatism correction during the same session. It is also useful when consistent capsule shape and lens positioning are critical for visual outcomes.

SAFETY AND CLINICAL EVIDENCE

Multiple peer-reviewed studies show that femtosecond laser steps are accurate and predictable. Moreover, large clinical series confirm that FLACS is generally safe when performed by trained cataract surgeons using approved systems. Visual outcomes are comparable to excellent standard surgery, while precision steps are enhanced. Nevertheless, final results still depend on retinal health, optic nerve status, and correct lens selection.

IMPORTANT CONSIDERATIONS

Not every cataract case requires FLACS. Therefore, a full eye examination and imaging review guide the recommendation. Cost, lens choice, corneal shape, and ocular comorbidities also influence planning. Your surgeon explains the expected benefits, limits, and alternatives before scheduling surgery.
