• Under corrections: It is when the laser removes too little tissue from the eyes and that results in not getting the needed clear vision. It is more common with nearsightedness people.
• Overcorrections: It is the opposite of nearsightedness and it is when the laser removes too much tissues from the eyes. It is more difficult to fix than under …show more content…
They are:
• Photorefractive keratectomy: It is sometimes used for people who have a low to reasonable degree of nearsightedness or farsightedness. The surgery removes the thin surface layer of the cornea (epithelium) and then uses a laser to flatten the cornea or make its curve steeper. It is less common than the Lasik surgery because the Lasik involves less discomfort and scarring when healing.
• Laser-assisted epithelial keratomileusis (Lasek). Lasek is similar to Lasik surgery, but the surgery allows the surgeon to remove less of the cornea making it a good option who have very thin corneas. It is more recommended to people who play sports or have jobs at high risk of eye injuries because the thinner flap in the cornea will be less exposed to serious damage.
• Implantable lenses: Phakic lenses are lenses that are surgically inserted in front of the natural lens to improve vision. It can correct high amounts of nearsightedness which cannot be easily corrected by other surgical options. It is not as common as the others due to it being relatively
