Lasik Refractive Surgery
This is a corrective treatment of refractive defects by means of excimer laser acting on the dioptric power of the cornea.
In contrast to PRK Refractive Surgery, the corneal epithelium is not removed, but a corneal lamella of 60 to 70 microns is made with a microkeratome or femto laser (Femto Lasik), after which the laser treatment is carried out.
There is no post-operative pain as the corneal epithelium has not been touched, nor is the construction of the lamella painful, as the nerve endings of the cornea are interrupted when it is cut.
The patient's functional recovery is faster, gaining a few days at PRK. However, one month after the operation, with the same results, there are no appreciable clinical-functional differences between the two methods. The advantage of a faster recovery and the absence of postoperative pain are ruled out by the greater invasiveness of the method.
Pre- and Postoperative Examinations for Lasik Refractive Surgery
The pre-treatment examinations for Lasik Refractive Surgery are those necessary for a corneal morphometric evaluation (topography, pachymetry, endothelioscopy), for the study of corneal dynamics (pupillometry) and for a correct calculation of the refractive defect (visual acuity examination in cycloplegia).
The same examinations are then repeated after the operation to monitor the outcome of the treatment.
Recovery Time for Lasik Refractive Surgery
Recovery times are variable according to the type and extent of the visual defect; an average of 4-5 days' rest after treatment can be estimated.
