Abstract Details

Purpose:

Refractive surgery refers to the surgical or laser procedures used to reduce the reliance to optical correction via glasses or contact lenses. It is effective in the correction of one or a combination of ametropia. Amongst the most used corneal techniques are: LASIK, laser of surface PRK and trans PRK. Above a certain level of ametropia, only surgeries to install intraocular implants. The purpose of our study is to list the different techniques used depending on the type and importance of ametropia, and to evaluate the refractive outcome and predictability of each technique.

Setting:

All of our patients benefited from a complete pre refractive assessment including: topography and specular microscopy, topography with elevation, orthoptic assessment, refraction, mirror examination of the fundus, study of the corneal biomechanic (ORA).

Methods:

We did a retrospective study on all of the procedures with a refractive objective done at the “Clinique de l'Oeil” between June 2013 and November 2015.

Results:

During those 2 years, 1711 patients (3412 eyes) benefited from refractive surgery. The mean age of our population was 33 years old, the sex ratio 0.41 predominantly females. The techniques were divided as follow: Trans PRK: 2350 eyes, Femto Lasik: 308 eyes, ICL: 754 eyes. The low to medium myopias -[-1 to -6] benefited from Trans PRK in 88,5% of the cases, and Femto Lasik in 11.5% of the cases. Every major myopia (myopia <-7) benefited from an ICL surgery with excellent results with only 4 cases of transitional hypertonia occurred corrected by a local treatment.

Conclusions:

The return towards surface treatment in refractive surgery allowed us to combine safety and satisfactory outcomes with the technique of Trans PRK. Indeed, these results have been confirmed by several studies worldwide. The high ametropias benefited from the improvement of spherical and toric ICL implant design. Refractive surgery seems to be taking the path of reason as we notice a return to safer techniques, with more historical data, as the PRK and the Trans PRK. The Femto Lasik remains the first choice for patients older than 35 years and the hyperopic population.
