Conventional LASIK and Poor Vision in Low Light Conditions

Oklahoma City LASIK and Poor Night VisionLASIK surgery is a great option for patients who are tired of relying on corrective lenses for clear vision. The results of LASIK surgery leaves patients free to enjoy near-perfect vision without the hassle or inconvenience of glasses or contact lenses. However, one drawback to conventional LASIK surgery is that it does not correct higher order aberrations such as poor night vision. Oklahoma City who undergo conventional LASIK may notice that poor night vision remains after surgery. At Advanced Laser & Cataract Center Oklahoma, our eye doctors perform custom wavefront LASIK to correct higher order aberrations that result in poor vision in low light conditions.

Why Does LASIK Affect Night Vision?

When conventional LASIK is performed a corneal flap is created using a microkeratome or laser. A potential side effect of this procedure is the appearance of glares or halos in the vision, especially at night. While most patients experience these halos temporarily, they do remain a long-term problem for some. While not often a problem during the day, glares and halos can significantly impact night vision and night driving.

Poor night vision is also the result of higher order aberrations, vision problems that affect a person’s quality of vision. Unlike lower order aberrations (more commonly known as nearsightedness, farsightedness, and astigmatism), higher order aberrations can’t be corrected with conventional LASIK. These unique errors can only be identified with wavefront technology, which is employed when patients undergo the custom LASIK procedure.

Preserving Night Vision

The results of LASIK are overwhelmingly positive for patients, with the majority of patients achieving a vision of 20/20 or better. However, it is important to consider the risk of decreased night vision, especially for patients who do a lot of night driving. Fortunately, we are able to offer our patients a more advanced form of LASIK treatment. Bladeless LASIK reduces the risk of complications such as halos and glare; custom wavefront LASIK can be performed to correct higher order aberrations, such as those that result in poor vision in low light conditions.

The bladeless LASIK  procedure is very similar to that of conventional LASIK. However, during a bladeless LASIK procedure, the corneal flap is created using the IntraLase® laser. This provides our eye surgeons with improved control and precision. The result of this technique is safe, fast, and effective vision improvement with virtually no risk of flap complications.

Custom LASIK involves the use of wavefront technology to detect and map out higher order aberrations. This map guides the excimer laser as it reshapes the cornea, correcting both the lower and higher order aberrations that affect vision.
