The retouching consists of lifting the corneal flap and redoing an additional excimer laser treatment. When a touch-up is necessary after surgery for myopia, we know it quickly, and there is no need to wait indefinitely. In practice, however, experience shows that it is still possible to lift a bonnet without difficulty several years after the intervention. If the delay is even longer, it is always possible to carry out a complete intervention, thus making a new corneal cut.
What Are The Essential Risks Of Myopia Surgery?
Myopia surgery with kraff eye institute for example is no exception to the rule that there is no zero risk in surgery. However, in the case of a surgery that will concern a healthy organ and does not correspond to a medical necessity, it is essential to approach zero risk as closely as possible. This is the whole point of the very rigorous assessment carried out before any myopia surgery, which will make it possible to eliminate patients who do not offer optimal safety conditions. This eliminates the risk of severe complications, which are only observed today in cases where a detailed analysis of the corneal morphology should have rejected surgery.
Of course, infectious complications are always possible, although exceptional and infinitely rarer than the sometimes very serious infectious accidents observed in contact lens wearers.
Apart from this, some patients may complain of qualitative alterations in vision which can sometimes make it more difficult to drive at night, but these phenomena are often expected in patients with large pupils who already experience these difficulties even before surgery, especially when wearing contact lenses.
The most common risk (5%) and the most benign remains under correction, the only consequence of which will be the need for a touch-up.
Is The Hindsight Sufficient Today In Laser Myopia Surgery?
Yes, undoubtedly, because surface techniques (PKR) are almost 25 years old today, and the lasik eye surgery and LASIK laser is almost 20 years old, which is huge for a myopia surgery technique. In addition, the principle from which the LASIK laser is derived, i.e., the isolation of a corneal lamella and the modification of its thickness and curvature, is already half a century old! What has changed is the method for carrying out this corneal remodeling, but the principle is already very old. We have no concerns about the future of the operated eyes, a fortiori with the increasingly fine investigations that allow us to eliminate eyes presenting, even in the very long term, a risk, even minimal, of corneal ectasia.
