Nightime Glare Following Cataract Surgery
by RonS912, Jul 17, 2008 02:49PM
In May of this year I had a cataract lens removed from my left eye and replaced with a monofocal lens. In June the same operation was performed on my right eye. Deteriorating night vision with auras around lights was a primary motivation for having this surgery. The auras are no longer a night vision problem but have been replaced post-surgery by an approximately 5 degrees of arc array of very fine, very bright lines of light emanating from directly opposite sides of the central source of any bright light with the 180 degree opposing narrow arrays residing at fixed angles of about 20 degrees and 200 degrees (20 + 180) clockwise rotation from vertical (left eye) and 110 degrees and 270 degrees (110 + 180) clockwise rotation from vertical (right eye). The bright line arrays extend outward from either side of the central bright light source (such as a car headlight) to the outer edge of the field of vision and rotate as my head rotates indicating they are fixed property of the eye’s lens system. Assuming this optical result is associated with the monofocal lens, the only feature of such a lens that might relate to it are the haptics which extend 180 degrees either side from the lens and become fixed to the capsular bag. Further, the bright lines seem to behave somewhat like a diffraction grating, breaking light into faint bands of rainbow colors. I cannot be the first cataract patient to experience such a vision problem and wish to know both the origin and what should be done to correct this seeing difficulty so night driving, especially can be made safe.

You could be noticing glare due to wrinkles or cloudy areas in the posterior capsule. I would have surgeon determine:
1. is IOL centered or dencentered ?
2. is IOL in normal condition without scratches or tears?
3. are there wrinkles or stria in posterior capsule?
4. is there posterior capsule haze or PCO?
5. is there damage to the iris with light streaming through certain areas?
6. is the cornea clear?
7. is there residual refractive error especially astigmatism?
