Surgery for High Myopia and Astigmatism
In cases of myopia or other refractive defects associated with high astigmatism, where the suitability and safety parameters for excimer laser treatment cannot be met, there are surgical alternatives with different degrees of invasiveness.
It is a precision surgery and certainly rehabilitative for the patient suffering from limiting refractive errors.
We can use phakic intraocular lenses (IOLs), which are implanted in the patient's eye in the presence of his natural crystalline lens: it is like inserting a contact lens inside the eye, close to the natural crystalline lens and able to correct the high refractive defect. This is also applied in the presence of high astigmatism, which is difficult to correct with traditional systems.
Another surgical strategy is to remove the natural crystalline lens and insert an artificial lens (IOL) capable of correcting both the high spherical refractive defect (high myopia, hyperopia) and the associated astigmatism. These are toric IOLs that can be oriented inside the eye according to the axis of correction of astigmatism.
Pre- and Postoperative Examinations for Surgery for High Myopia and Astigmatism
The pre- and post-operative examinations are the morphometric examinations of the eye required for refractive surgery: corneal topography, pachymetry, endothelioscopy, refractive examination in cycloplegia and aberrometry.
Recovery Time for Surgery for High Myopia and Astigmatism
Recovery times are comparable to those of age-related cataract surgery: a few days of rest are enough for healing and functional recovery.
