- Vision correction: The doctor uses another type of laser to reshape the inner corneal tissue and correct vision. The doctor asks you to focus on a specific focus of light.

The latest vision correction surgery 2022: Femto Lasik
In the traditional LASIK procedure, doctors relied on the use of the blade, which is a microscopic tool that removes a thin layer of the surface of the cornea, which is lifted so that the laser energy is used to reshape the eye to correct vision, but with time the technology was developed where the blade was replaced by a type of high-energy laser (femtosecond laser). Now, most surgeons in LASIK procedure rely on this completely bladeless technology, which makes the procedure faster, more accurate and safe. Patients recover faster based on this technology.
One of the patients’ biggest concerns when considering LASIK is eye movement during the operation. The latest vision correction procedures 2022 allow 3D tracking and recording of the iris of the eye. The laser tracks the slightest eye movements during the procedure and makes accurate adjustments as needed, ensuring better results.
Finally, one of the latest vision correction surgeries 2022 is the Femto Lasik procedure, which treats both nearsightedness and astigmatism. The laser is used to create a thin layer under the surface of the eye in the form of a contact lens, which is then removed. The procedure corrects the patient’s vision with a quick recovery period. No restrictions after LASIK surgery.
