Recent advances in visioncorrection surgeries have been remarkable. But it can be difficult to see through all the medical jargon to understand what applies to our own eyes.
To get a good grasp, let’s assemble people into three age groups: 18 to 45, 46 to 65, and 66 and older.
In the 18 to 45 age group, Lasik is the top choice. Recent Lasik advances include wave front, astigmatism correction and blade-free Lasik.
FDA approval for laser vision correction starts at age 18. By that age, eyes start stabilizing. It is important to confirm that the eyes are stable.
Since Lasik is much safer than contact lenses, it is a natural choice for athletes and collegebound students.
In wave front technology, the entire treatment is executed with computers and lasers. With oversight by a skilled Lasik surgeon, a beam of light is first sent into the eye. This bounces off the retina and gets grasped and analyzed by the computers in the wave front machine.
Unlike a traditional eye exam at the optometrist, where asking “Is one better or two?” can drive a client nuts, the computerized analysis increases the accuracy. In fact, the level of accuracy with the wave front laser is nearly 100 times more than glasses or contacts.
Incorporating iris registration increases the accuracy of delivery. Here the laser identifies landmarks on the iris, the colored part of the eye, and moves with the eye.
The modern day flap-making devices are more advanced than the freehand blades of previous centuries. Today we have automated thin flap makers and the laser to create consistent uniform flaps.
There have also been different advances in FDA laser machines, such as Visx S4IR and Allegreto, which are the top two.
So today’s laser vision correction surgery is safer, longer lasting and provides better vision, especially at night, without any glare or halos.
