LASIK is considered one of the safest eye surgeries, with a worldwide success rate and patient satisfaction rate of over 96%.
The latest studies indicate that 99% of patients achieve 20/40 vision and 90% achieve 20/20 vision or better.
One of the main risks to be taken into consideration and present in any refractive surgery is the possibility of continuing to have a residual dioptric value, that is, the person's refractive error may not be corrected in its entirety.
Most of the time, this residue is not significant and may not even have any influence on daily vision.
In rarer situations, where the visual acuity obtained is not satisfactory, it may be necessary to perform a new surgery to correct the residual graduation, if the patient still has the necessary conditions for this.
Among the less common risks, corneal lesions associated with surgery can sometimes result, such as scarring, which can impair vision and make daily activities difficult. In the more specific case of IOL implantation, the risks are the same as those associated with intraocular surgery.
To avoid any risk of infection after surgery, it is very important to apply all the therapy recommended and prescribed by the ophthalmologist.
