Customised refractive surgery is adapted to the characteristics of the eye to achieve the best result. In some cases, standard laser eye surgery treatment is not enough. In addition to correcting myopia, hyperopia or astigmatism, we must take into account other defects that affect the patient’s vision.
We know that each eye is unique, no two are the same and sometimes it is necessary to use additional technology to guide the laser in order to achieve the maximum quality of vision. We currently use two devices in personalised refractive surgery: an aberrometer and a topographer.
Customised refractive surgery guided by aberrometry or wavefront
Customised aberrometer-guided treatment makes it possible to correct higher order aberrations. These are imperfections that affect the quality of night vision, resistance to glare, the ability to differentiate nuances in colours and brightness or that cause double vision.
When we correct vision with glasses, contact lenses or standard laser treatment, we assess the eye as a perfect surface with a single prescription over its entire area of vision. However, in some cases it is necessary to make a more thorough assessment. For this we can divide your optical zone of vision into hundreds or thousands of smaller areas and determine the prescription needed for each of them.
Personalised topography-guided refractive surgery
The topographer is able to generate a 3D image of the cornea. From this it is possible to detect any asymmetry or irregularity that is affecting your vision. Personalised topography-guided treatment can correct the curvature of the cornea and smooth or regularise its surface.
Customised laser eye surgery is ideal for people who do not have good vision with glasses. Precisely because this optical correction does not take into account the irregularities of their cornea. These are patients who may have good vision during the day, but at night or in poor lighting conditions where the pupils dilate, their vision worsens.
With these methods the application of the laser will be conditional on the information provided by the aberrometer or topographer. This helps the ophthalmologist to design a specific treatment for each eye to achieve maximum quality of vision. Ophthalmology clinics that do not have this technology will not be able to offer it to you and therefore the result of your operation would not be as good.
