Planning around your eye
Detailed imaging maps the front of your eye. Dr Chen uses these measurements to plan the position and size of the laser treatment.
Femtosecond laser cataract surgery
Image-guided laser precision for selected steps of cataract surgery. Dr Simon Chen offers femtosecond laser technology for cataract surgery.
What are the benefits of laser cataract surgery?
A precise capsule opening
The laser can create a circular opening of a planned size in the thin capsule around the lens. This gives a reproducible opening for cataract removal and implant placement.
Less ultrasound energy
Pre-dividing the cataract with the laser can reduce the ultrasound energy needed to remove it. The amount of reduction depends on the cataract and the surgical technique.
Protecting the corneal lining
Reducing ultrasound energy may help limit loss of corneal endothelial cells—the delicate cells that keep the cornea clear by controlling its water content.
This is particularly relevant when the cornea is compromised, such as in Fuchs’ endothelial dystrophy. A better corneal outcome is not assured: studies in Fuchs’ dystrophy have not consistently shown an advantage over standard surgery.
These are potential advantages within the operation. Greater technical precision does not guarantee better final vision or faster recovery for every patient.
How does laser cataract surgery work?
Cataract surgery replaces the cloudy natural lens with a clear artificial lens. A femtosecond laser can help Dr Chen perform selected steps before he completes the operation.
Image and plan
The laser system images your eye. A contact interface holds it steady while the treatment is planned and delivered. ZEISS CALLISTO eye digital guidance then carries your measurements into the rest of the operation, including the alignment of a toric lens.
Prepare the cataract
The laser can open the lens capsule and divide the cataract into smaller pieces. It can also create corneal incisions when these are included in the plan.
Complete the operation
Dr Chen removes the cataract using an ultrasonic phacoemulsification probe and inserts the chosen lens implant.
What should I ask about laser cataract surgery?
- Which parts of my operation would the laser assist with?
- What benefit do you expect for my particular eye?
- How do my retinal health and lens choice affect the plan?
- What should I expect during recovery and follow-up?
Common questions about laser cataract surgery
Is laser cataract surgery a different operation?
It is a variation of cataract surgery. A femtosecond laser assists with selected steps; the surgeon removes the lens material and places the implant.
Does the laser remove the cataract?
It can fragment the cataract, but the lens material still needs to be removed by the surgeon.
Would laser give me better vision?
Both standard and laser-assisted cataract surgery can provide excellent vision. Laser offers precision in particular steps, but final vision also depends on the lens implant, the health of your retina and the rest of your eye. Dr Chen will explain what benefit he expects from using it in your case.
Is the recovery different?
You will still need eye drops and follow-up visits. Your recovery is individual; it depends on your eye and the complete operation, including any combined procedures.
