Have you ever wanted to see clearly without the need for glasses and contact lenses? If so, there is a great laser vision correction solution that has helped millions around the world. We're speaking, of course, about LASIK surgery. LASIK uses safe laser technology to enhance the vision.
This eye care technology has been improving and evolving over the years. One of the best advances in recent years involves custom LASIK technology. We'd like to examine this right now with regard to night vision and what this means for patients.
About Traditional LASIK
A traditional LASIK surgery involves the reshaping of the cornea, the clear frontal portion of the eye. By reshaping the cornea, light passes through the eye and focuses better on the retina, which is the light-sensitive tissue located at the back of the eyes.
How Custom LASIK is Different
Custom LASIK uses advanced digital mapping technology in order to scan the corneal surface. This digital mapping technology allows for custom LASIK surgeons to pinpoint the most minute of corneal imperfections. This allows surgeons to address higher order aberrations and lower order aberrations. (Traditional LASIK can only treat lower order aberrations.)
About Lower Order and Higher Order Aberrations
Lower order aberrations are common refractive errors, which you probably know better as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.
Higher order aberrations are the finer vision issues that affect overall clarity of vision, such as poor night vision, poor color or light sensitivity, night vision issues, starbursts, glare, and halos.
Night Vision and LASIK Side Effects
A common side effect of LASIK surgery is poor night vision. This will be experienced because of the natural way that eyes heal following the refractive surgery. This is why patients need to be extra careful when driving at night in the weeks after LASIK. The night vision will resolve on its own in the weeks and months following surgery.
Reduced Issues with Night Vision Thanks to Custom LASIK
Thanks to custom LASIK, patients tend to experience less serious vision issues with night vision as they heal. In addition, once healing is completed, pre-surgical problems with night vision are often treated, allowing patients to see well at night.
What Custom LASIK Means for Patients
Custom LASIK surgery essentially means that patients are able to see even better today than the LASIK patients from 10 years ago. The custom LASIK technology offers so many advantages over traditional LASIK surgery, and reduces chances of human error as well.
Weighing All of Your Options for Vision Correction
Sometimes patients are not good candidates for LASIK surgery for a number of reasons. In these cases, we will consider other refractive surgery options that may prove helpful for the needs of a patient. We will work closely with each patient so that they are able to achieve excellent vision.
