How does Refractive Surgery work?
Presbyopia treatment usually involves glasses or contact lenses.Some people opt for refractive surgery options.
Eye Surgery
Eye surgery is a common treatment for vision problems, especially cataracts or squints.
The goal of refractive eye surgery is to reduce the need for eyeglasses or contact lenses.
LASIK (laser in-situ keratomileusis) Uses computer-controlled excimer cold laser and wavefront technology and microkeratome (femtosecond laser) to remove tissue by creating a corneal flap which then reattaches to the cornea.
Photorefractive keratectomy (PRK) The excimer laser beam reshapes the cornea by removing tiny amounts of tissue from the outer surface.
Radial keratotomy (RK) Tiny cuts (incisions) called are made in the cornea with a diamond scalpel. The cuts cause flatten the center of the cornea and change its curve.
Astigmatic keratotomy (AK) Instead of making radial incisions, the eye surgeon makes cuts in the cornea in a curved pattern.
Automated lamellar keratoplasty (ALK) The eye surgeon makes a deeper cut into the cornea with the microkeratome to make a flap
Laser thermal keratoplasty (LTK) Uses the laser to the edges of the cornea. This shrinks the collagen fibers and reshapes the cornea
Conductive keratoplasty (CK) It uses heat from low-level radio waves to shrink the collagen and change the cornea’s shape
Intracorneal ring (Intacs) They are thin rings that are implanted into the cornea. They change the curve of the cornea
