Lasik, Bladeless Lasik, PRK, etc.
from light sources can occur naturally, can be exacerbated by
refractive surgery, or can be induced by refractive surgery.
Naturally occurring daytime starbursts may be caused
by dry eye,
epithelial problems, or
higher order aberrations within the optics of the eye.
A comprehensive examination before surgery including
wavefront aberrometry can help to determine if the patient is predisposed
to an increase in starbursts with refractive surgery.
Daylight occurring starbursts
after conventional or
Epi-Lasik, may be caused by uneven or rough
ablations, induced temporary dry eyes, induced epithelial problems,
striae, or slow healing issues.
Starbursts that occur only in low light environments
after conventional or wavefront Lasik, All-Laser
Lasik, PRK, LASEK, or Epi-Lasik tend to be caused by undercorrection,
residual or induced astigmatism, or optical ablation zones smaller than
the naturally dilated pupil. See
Pupil Size for a
detailed explanation of pupil size and ablation size issues.
In many cases, both daytime and night time refractive
surgery induced starbursts dissipate with healing. An evaluation by
a competent doctor is necessary when starbursts after refractive surgery
are greater than before surgery.
If you are ready
to choose a doctor to be evaluated for Lasik or any refractive
surgery procedure, we highly recommend you consider a doctor who
has been evaluated and certified by the USAEyes nonprofit
