REFRACTIVE SURGERY

INDICATIONS OF EACH TECHNIQUE

Radial keratotomy : Myopia from -1 to -3 diopters
PRK or Lasek : Myopia from -1 to -3 diopters, astigmatism from -1 to -3 diopters
Lasik :
- Myopia : -1 to -10 diopters
- Astigmatism : +/- 1 to +/- 5 diopters
- Hyperopia : + 1 to + 5 diopters
Aberrometry: Wavefront Customized treatment by aberrometry and Ultra Thin Lasik :
- Myopia : -1 to -10 even up to – 12 diopters
- Astigmatism : -1 to -6 diopters
- Significant optical aberrations
- large pupillary diameter in dim light
- Indication to enhance visual acuity
- Thin cornea

Particularities of each technique

RK, PRK, Lasek and Lasik can induce a regression or a postoperative under-correction of the ablation profile due to individual variability of the human corneal tissue.
In 4 to 5% of cases, a free retreatment is necessary
(according to results from Doctor Assaf).
Retreatment is less frequent with customized treatment by aberrometry, estimated from 2% to 3%.
Retreatment for over and under correction after RK and PRK can be performed by PRK and LASIK.
Retreatment following Lasik is always done by Lasik
