The refractive surgery is a group of different operations, which all have the purpose to correct the refractive errors (myopia, astigmatism, hypermetropia, presbyopia) of the candidates. They have excellent results and the satisfaction of the operated people is up to 95%, which is the highest percentage in the aesthetic surgery. In detail:
I) (Trans-) PRK
We remove the epithelium (the outer layer of the cornea) and then using the excimer laser on the stroma (the middle layer of the cornea) we make such an ablation so as to correct the refractive error of the patient. The technique is easy to make and has excellent post-operative corneal stability.
II) (Femto-) LASIK
We initially create a 80µm flap (with the Femto laser) and then, after folding it on the side, using the excimer laser on the stroma (the middle layer of the cornea) we make such an ablation so as to correct the refractive error of the patient. The advantage of this technique is the quick rehabilitation, as the patient can go home and see very well immediately after the operation.

III) Intraocular lens (ICL)
The ICL is a special artificial lens, that is placed surgically between the iris and the natural lens. The power of the lens is the one needed to correct the refractive error of the patient. It is like a contact lens placed inside the eye. This technique is ideal for cases with very big refractive errors, which cannot be corrected with the laser methods.
IV) Clear Lens Extraction (CLE)
The clear lens of the patient is removed and exchanged with an artificial one, the power of which corrects the refractive error of the patient. This method is used as above, just by older patients, over 40-50 years old. If multifocal lenses are used, they can also correct the presbyopia.
Minimonovision is a trick, which we can use in combination with the PRK or the Lasik, in order to treat partially the presbyopia. Specifically on the secondary eye 0,75 dioptries myopia is left, which helps the patients in the near area, without real concerns on the far-seeing.
