Why Is Lasik Surgery The Most Used Refractive Surgery Technique?
Currently, there are different surgical procedures to correct refractive errors such as myopia, hyperopia and astigmatism. Of all the possible options, the one most used and recommended by ophthalmologists is Lasik surgery, basically due to its great safety, efficacy, simplicity and minimal discomfort and complications for the patient.
What Is The Lasik Technique?
This technique is based on the use of a last generation laser, called Excimer, to resculpt the cornea. However, before carrying out the operation, we need to consider the Lasik pros and cons.
While operating, the surgeon lifts a very thin layer of the corneal tissue, then the laser is applied, which is later repositioned without the need to apply stitches.
Main Advantages Of The Lasik Technique
- Maximum Security
The Excimer laser has an automatic safety mechanism, called an eye-tracker, which guarantees that the impacts are made only in the areas of the cornea that need to be corrected.
- High Efficiency And Reliability
It is a technique that has been practiced for several decades, so the professionals who perform it have acquired great experience, which, added to the important technological improvements, make the vast majority of patients achieve a fully satisfactory visual improvement.
- Minimal Discomfort For The Patient
It is an outpatient surgery, so it does not require hospital admission. The discomfort is very few, and in a couple of days, the patient can already lead a practically normal life.
Complications And Limitations
The Lasik technique is a very effective and safe surgical procedure and for this reason, it is the type of surgery most used by ophthalmologists around the world to solve refraction problems. However, there is the possibility of some complications:
- As a secondary effect to the operation, dry eye syndrome can occur; a mild and transitory alteration that causes discomfort such as irritation, stinging or redness.
- Sometimes, it may be necessary to carry out a touch-up to fix a small residual visual defect.
- Although it is very rare, inflammation or infection can occur.
In any case, these are minor and temporary problems that can be avoided or minimized with proper precautions and appropriate measures.
When The Refractive Problem Is Not Yet Stabilized
To verify that the patient meets the requirements and, therefore, is a candidate to say goodbye to glasses and contact lenses, thanks to a refractive surgery operation using the Lasik technique, the ophthalmologist will perform the necessary tests (all of them quick and painless) in a prior consultation.
