“What are the disadvantages of laser cataract surgery?”

The experience of the doctor is most important

The biggest issue with laser-assisted cataract surgery is the added cost that is not covered by insurance. This dollar amount should be discussed with your surgeon so that you are aware of all financial requirements before and after your surgery, including copays that you may be responsible for.

"Surgeons pay for the laser machine, they pay for interfaces used for each case, they pay a royalty fee on each case, and they pay a significant yearly maintenance fee to keep the lasers working. These costs are not paid for by insurance companies and so the cost has to be incurred by the patient." From the website:

There is also a risk that the laser energy can make a dilated pupil smaller causing a small risk of surgical complications. You should discuss all of your concerns, questions, financial responsibilities, risks, and benefits with your surgeon, always. Good luck and best wishes.

every surgery has risks... infection, etc
but, a relatively easy surgery in general
