Those who suffer from vision dysfunctions and refuse to wear contact lenses can now turn to laser surgery , a very useful tool used in multiple fields of ophthalmology. In particular, it is used in corneal surgeries to solve refractive problems such as myopia, hyperopia or astigmatism ; and in intraocular surgeries to solve diseases such as glaucoma (which involves the progressive loss of optic nerve fibers) or retinal pathologies. In this type of cases, the laser is applied in the surgery of the eyelids and also in the lacrimal obstructions.
It is a non-aggressive surgery, since its action is very selective, but we must not forget that, like any surgical operation, it involves a certain degree of risk. The patient must take this danger into account and accept it, and the surgeon has to put all his knowledge and the necessary means to minimize it.
Safe and with good results
Virtually all people who have vision problems (or refractives) and do not want to wear glasses can undergo laser surgery. Also those who suffer from other ophthalmological dysfunctions , whether intra or extraocular. The results in this type of interventions are usually always fast. If we refer to the laser of refractive surgeries (for example, to solve myopia), the results are almost immediate, since the patient in less than 12 hours already has a practically normal vision. However, the result is slower in other fields of ophthalmology. Even so, the most important thing is that the solution to the vision problem is durable, complete and safe .
Evolution of the treatment
The advances in the field of laser surgery are constant and very diverse. A good example of this evolution is the use of laser-mediated surgery to solve the lacrimal obstruction , since its use helps to complete the unclogging of said lacrimal organs in a non-aggressive and safe way, improving the patient's postoperative period in relation to the conventional previous operations. We must also highlight the constant progress in lasers that treat retinal diseases such as retinal detachment or diabetic retinopathy (damage to the blood vessels of the retina that can cause a blood leak).
