A preoperative assessment is essential in refractive surgery. It allows your surgeon to choose the most appropriate surgical technique for you (which may be PRK, LASIK, SMILE, or implants) and to check the absence of contraindications.
Indeed, even if refractive surgery corrects visual defects (myopia, hyperopia, and astigmatism), compliance with the contraindications avoids post-operative complications. The quality of the preoperative indication determines the quality of the result. This consultation also helps to answer your questions.
At Clinique de la Vision, for example, a preoperative consultation includes:
- measurement of ametropia (visual defect) to be corrected by refraction analysis
- the verification of the “dominant” eye (or “director”) essential when correcting symptoms of presbyopia
- the complete ophthalmic assessment with measurement of the intraocular pressure, examination of the fundus and especially the analysis of the transparency of the lens
- The analysis of corneal morphology (curvature, shape, thickness) thanks to corneal topography eliminates the contraindications to laser surgery and to choose the most appropriate surgical technique for the patient
- Aberrometric examination analysis of the optical quality of the eye
- Calculation of the implant is performed if lens surgery is considered
- Other explorations can be done depending on the context.
It is only at the end of this assessment that a surgeon can make a recommendation, and choose the most suitable refractive surgery technique for you.
The surgeon will clearly explain the advantages, the possible undesirable effects and the expected results of their recommended procedure.
