Understanding Night Vision Symptoms

ARSC-Donnenfeld-Night-VisionWhen you look at a light source – like a headlight or a streetlamp – do you see a halo around or a starburst over it? Do you see glare or ghosted images at night? These night vision symptoms – glare, halos, starburst and ghosting – happen because light doesn’t focus properly into the eye. Everyone’s eyes naturally have microscopic imperfections of the cornea and lens, which can scatter, rather than focus light with precision into the eye.

Recent research shows today’s modern LASIK technologies significantly improve the quality of vision for the majority of patients, including fewer night vision side effects. In fact, night vision symptoms related to LASIK have recently been studied* and, when the latest technologies are used, the majority of patients find their night vision symptoms are reduced after LASIK. Here are some of the recent statistics related to LASIK and night vision symptoms:

 

Glare: 19 percent of patients developed new glare symptoms; 66 percent of patients reported their pre-existing glare symptoms resolve within 3 months after LASIK.

 

Halos: 35 percent of patients developed new symptoms of halos around light sources; 50 percent of patients reported their pre-existing halo symptoms resolve within 3 months after LASIK.

 

Starbursts: 31 percent of patients developed new symptoms of starbursts around light sources; 50 percent of patients reported their pre-existing starburst symptoms resolved within 3 months after LASIK.

 

Ghosting: 5 percent of patients developed new ghosting symptoms; 90 percent of patients reported their pre-existing ghosting resolve within 3 months after LASIK.

 

Just like any surgery, there are risks with LASIK to be aware of in order to make an informed decision. LASIK is an excellent procedure with an extremely low – less than 1 percent – risk of significant, sight-threatening issues. This is far less than the potential problems associated with contact lens use. During your initial consult, you should come prepared to discuss not just your vision, but the quality of your vision including your existing visual symptoms such as glare and halos.
