1. PRK or Photorefractive Keratectomy
This procedure is almost the same as Lasik but without the flap. A very thin surface layer of your cornea is taken out before the laser procedure is conducted.
PRK is designed for near and far farsightedness. It can also be used for patients with astigmatisms. This is an ideal option for individuals with thin corneas
Its main advantage is that it has been used longer than Lasik. however, compared with Lasik, this procedure takes longer time to recover.
2. Lasek
It's fancier than Lasik. Unlike Lasik, this procedure causes less haze from collagen buildup. Unfortunately, this claim has not scientific basis yet.
Lasek is ideal for patients with thin corneas and for indivduals who are near or farsighted. People with astimagtism may also take advantage of this eye procedure.
It has similar benefits as PRK but its recovery time is a bit trickier than Lasik.
3. Wavefront Laser Surgery
This is an advanced procedure that lets surgeons to correct a person's unique corneal flaws. You can be a good candidate for this procedure if you are nearsighted or you have astigmatism. Some patients who cannot undergo Lasik can take advantage of this eye procedure.
The result of this procedure offers a super vision that is better than 20/20. However, it is costlier than the regular Lasik.
4. Conductive Keratoplasty
This is a more improved procedure of LTK, which is an old eye procedure that corrects and eliminates cataract. CK utilizes radio waves, instead of lasers.
This procedure is intended for people with mild to moderate farsightedness. It is also recommended for patients who do not want to wear reading glasses.
Compared with laser procedure, this one is faster and it is designed for those who are afraid of laser. However, the result may fade with time. Another disadvantage of this procedure is that surgeons will insert a tiny material into the cornea, which can be a little irritating.
5. Intraocular Lenses
This procedure will remove your old lens and replace them with an artificial one called Phakic. It is a disc that will sit between the cornea and the natural lens.
It is designed for patients with extreme near and farsightedness, which cannot be treated by Lasik.
The accuracy of this procedure is way better than Lasik. It retains the protective layer of the cornea. Unfortunately, this is prone to infection. Plus, it is more expensive than Lasik.
