PRK (Photorefractive Keratectomy) is a surgical procedure that involves removing a thin layer from the surface of the cornea, leaving a connected portion to the eye. The laser is then used, and the surface layer is replaced to its natural position.
Types of LASIK:
Surface LASIK:
This is a procedure that is performed on the outer surface of the cornea to correct refractive errors with a laser. It is a well-known technique in laser surgery for correcting vision and improving visual acuity, and is recommended for individuals who engage in high-impact and combat sports.
Femto-LASIK:
This is one of the most advanced vision correction surgeries and is used to correct corneal irregularities. It is considered one of the safest LASIK procedures.
Custom or Wavefront LASIK:
This technique is considered one of the most advanced LASIK technologies that uses electronic link between two devices, the laser and the camera of the cornea. The camera captures the cornea's unique fingerprint and sends the image to the laser. The doctor then enters the patient's prescription, which allows the laser to correct all vision errors with extreme precision.
