Laser Lens Exchange
Precision surgery with the femtosecond laser
The Laser Lens Exchange at a Glance
- During this procedure, the eye's own natural lens is removed and replaced with a synthetic lens.
- A lens exchange is used for correction of :
» nearsightedness from -8 dpt.
» farsightedness from +4 dpt.
» astigmatism (with so-called toric lenses)
» astigmatism (with multifocal lenses) - The femtosecondlaser assisted lens exchange is known for the high potential of exact predictability, the reproducibility of the surgical success and the reversibility of the procedure.
- The lens exchange always results in a loss of accommodation so that reading glasses are usually needed.
- A multifocal lens can provide relief for presbyopia at well as for nearsightedness or farsightedness.
How does the surgery work?
At FreeVis, we use the femtosecond laser for the first four steps of the procedure: First, the laser liquifies the natural lens. Next, the laser is used to cut a circular opening into the lens capsule and a small incision in the periphery of the cornea. Finally, the femtosecond laser can also be used to correct an accompanying astigmatism.
After the aspiration of the lens material, the multifocal lens is folded and injected into the eye. Once in the eye, it unfolds and takes the place of the eye's normal lens. This surgery is also performed routinely for the removal of opaque lenses, the so-called cataract. Hence, this surgery technique is very reliable and proven. The use of the femtosecond laser further increases its precision and safety.
The video demonstrates how the use of the LensX femtosecond laser can improve the outcome of cataract surgery.
Typical course of surgery and postoperative recovery
The implant of a synthetic lens is an outpatient procedure. Usually, it is only necessary to anesthetize the eye with eye drops. Surgery is performed on each eye individually, with one or two days between procedures. On the day of surgery, a bandage is provided for your eye. One day after surgery, your vision is already improved, however final stability is only obtained approximately 8 to 12 weeks after surgery.
Which problems can occur during or after surgery?
Please note that the procedure involves a surgery in the inner eye, meaning that in extremely rare cases, severe side effects (such as infections) are possible. Sometimes, a secondary cataract may occur behind the new synthetic lens within months to years. It can easily be treated with a laser without the need to open up the eye.
What can you do to see well with intraocular lenses?
- Do not rub on your eyes for the first few days after surgery.
- Apply the eye drops regularly as prescribed by your physician; only use the eye drops for the amount of time specified by your physician; extended use of this powerful medication may be harmful to your eyes.
- Keep appointments for your postoperative eye exams.
- Schedule a checkup once a year so that possible long-term effects can be detected early.
- Contact your physician immediately if you experience severe pain or a sudden decrease in vision.
A few problems may occur that are beyond your control
such as glare and halos at twilight and at night, an infection, an increase in internal pressure of the eye, opaqueness of the cornea or secondary cataract.
Treatment costs
The treatment costs for vision correction surgery are generally not reimbursed by the statutory health insurance. This also applies to the initial (pre-op) consultation and follow up exams after the procedure. The treatment is billed according to the doctor's fee schedule (GOÄ).
