Disadvantages of femtosecond laser-assisted cataract surgery: high cost of surgery, slightly complicated procedure. 1. High cost of surgery: Femtosecond laser is currently not covered by health insurance and is expensive in itself. The procedure is more expensive than traditional cataract surgery with the addition of the cost of the femtosecond laser. 2. Slightly complicated surgical process: Femtosecond laser can only complete the key steps such as incision, tearing capsule, splitting nucleus, etc., which are operated manually in the traditional surgery, and it also needs to use ultrasonic emulsifier to complete the steps such as suctioning out of nucleus fragment and cortex, etc. The operation table needs to be changed during the operation. Intraoperative table changes are required. When encountering corneal white spots or local media turbidity affecting the passage of the laser, incomplete tearing of the capsule will occur, and manual repair of the tearing will also be required. Femtosecond laser-assisted cataract surgery is a slightly more complicated procedure than traditional cataract surgery, and requires different specialized equipment to complete the entire procedure.
