Complications & risks of Lasik eye surgery
Night vision problem, Night Glare, Halos, Night-driving problem
Clinical trials for LASIK
demonstrates that six months after LASIK eye surgery, 19.3% have
Night vision problem, Night Glare, Halos and Night-driving
problems
Night Glare and Halos are common for people who wear
glasses and especially contact lenses. When the pupil dilates at
night in, peripheral light rays are scattered more before they
reach the retina.
However, these symptoms are sometimes more bothersome after
Laser Eye Surgery. At least some temporary glare and halos
during the immediate recovery. This can last for weeks to first
three months and is due to corneal swelling and reorganization
of the corneal architecture. The overwhelming majority of
significant glare problems resolve on their own by six months.
The following factors are related to night vision problem :
● High degrees of myopia (> 5 diopters)
● Age greater than 50 years old
● Small diameter treatments (<= 6.0 mm)
● Residual astigmatism after Lasik eye surgery
● Residual myopia or hyperopia (> 0.50 D) after Lasik eye surgery
Reasons of Night vision problem, Night Glare, Halos, Night-driving problem after Lasik
Short-term of Night Glare and Halos are common cause of
corneal swelling and reorganization of the corneal
architecture after Lasik eye surgery. -
Persisting glare and haloes after LASIK have several possible
causes. The most common is residual refractive error. The
remaining myopia , hyperopia, or astigmatism from an
over-response or under-response of your cornea to the treatment.
In these cases, a pair of prescription glasses or custom/
wavefront LASIK eye surgery can solve the problem.
-
Glare and halos may also occur if the pupil enlarges beyond the
area of Lasik or when there is a decentered ablation.
Treatment to Night vision problem, Night Glare, Halos, Night-driving problem after Lasik
-
Short-term of Night Glare and Halos : It usually improve in the
first 3 months, and the overwhelming majority of significant
glare problems resolve on their own by six months.
-
Persisting glare and haloes after LASIK because of residual
refractive error : Custom / Wavefront LASIK eye surgery should offer
a refined method in the next 12 months.
-
Persisting glare and haloes after LASIK because of the pupil enlarges
beyond the area of Lasik or when there is a decentered ablation : A eye
drop to shrink the pupil. Eye color-changing soft contact lenses may
reduce glare and halos by making the functional pupil smaller
