What is the difference between full femtosecond surgery and laser myopia surgery?

Guangzhou All Femtosecond Hospital is a medical institution focusing on ophthalmic surgery, providing various treatment schemes such as all femtosecond surgery and laser myopia surgery. Although both operations can effectively treat myopia, there are some differences in technical principles, surgical procedures, postoperative recovery, etc. The differences between the two operations will be described in detail from four aspects.

Operation principle

Full femtosecond surgery is to use femtosecond laser high-energy pulse to accurately peel off corneal tissue, and correct the cornea with corresponding thickness by laser, thus changing the curvature of the cornea and optically correcting myopia. It is characterized by small trauma, high accuracy, and can be operated without damaging the corneal surface.

In contrast, laser myopia surgery uses laser beams to ablate a layer of corneal tissue to change the curvature of the cornea, thus correcting myopia. This operation needs to cut the upper layer of the cornea, so a certain recovery time is required after the operation.

Operation process

There are also differences in surgical procedures between full femtosecond surgery and laser myopia surgery. All femtosecond surgery uses femtosecond laser for corneal exfoliation and laser correction. The whole operation process is automatically completed by the laser. The operation time is short and the postoperative recovery is fast. However, laser myopia surgery requires multiple steps, such as corneal cutting and corneal ablation. The operation time is relatively long, and the postoperative recovery time is also long.

Surgical effect

All femtosecond surgery and laser myopia surgery also have different surgical effects. Full femtosecond surgery can achieve better correction effect because of its fine operation and less damage to corneal tissue. The laser myopic surgery needs to cut the upper layer of the cornea, so the surgical effect is slightly different from the full femtosecond surgery. However, both of the two surgical effects can significantly improve patients' myopia and improve their visual quality.

Postoperative recovery

There are also differences in postoperative recovery between full femtosecond surgery and laser myopia surgery. Because the full femtosecond surgery has less trauma, rapid postoperative recovery, less discomfort, and almost no risk of corneal opacity. However, laser myopic surgery requires corneal surface healing, with relatively long recovery time and a certain risk of corneal opacity.

To sum up, there are obvious differences between the full femtosecond surgery and laser myopia surgery provided by Guangzhou All Femtosecond Hospital in terms of surgical principle, surgical process, surgical effect and postoperative recovery. Patients can choose appropriate surgical methods according to their own conditions and doctors' suggestions to obtain better visual correction effect.
