My Old Fart Eyes
© 2014 – Ed Harris
I am now 64. In
2008 I had a retinal detachment in my dominant right eye, caused by a workplace
injury, which was repaired using vitrectomy and internal drainage in which a
gas bubble was injected into my eye to hold the retina in place, while its
edges were tacked in place with a laser. The surgery was completely successful,
but a year later the eye developed a significant cataract, which was removed.
During the cataract surgery I had an intraocular implant of
intermediate focus inserted into my right eye.
Objects from 20-40 inches away are in sharp focus, I use a slight
correction for distance and for precision close work. I can read the Wall
Street Journal under good light, or work on the computer without corrective
lenses and no longer have a corrective lens restriction on my driver's license.
My vision is 20-20 with glasses. The sights on my carry gun are sharp without
glasses when I extend the gun in 2-handed Isosceles.
Before suffering the detached retina I competed in
high-power rifle and indoor bullseye pistol shooting having shooting using
glasses approximately -0.5 diopter less than my reading prescription. My
shooting glasses were optimized for a focal length based upon the measured
distance my cheek bone below the eye to the front sight, approximately 39
inches for me. This gave a sharp sight picture, but the target was fussy if I
used only my right eye. The target would sharpen considerably if I also used a
Merit adjustable iris with the corrective lenses, but this isn't always
practical in dimly light indoor ranges. But it works great outdoors for pistol
shooting in full sun.
When shooting service rifle outdoors I could read the
number boards OK with my left eye, but when down in position looking through
the sights it was necessary to count target frames to be sure I was on the
right one, so that I wouldn't crossfire. I could hold 6:00 OK on the bull for
standing, 200 and 300 rapid, but would frame the target at 600. Back in the 1980s I shot Master, but these
days I'm Expert.
I could use a scope if the eye lens was backed off to
put the reticle in sharp focus without corrective lenses, and I could hunt with
no trouble. Firing a shotgun or iron sighted rifle I shoot with both eyes open,
as I have good distance vision in the left eye. The brain has no trouble
merging the target image in the left with the sight image in the right.
I was told by my retinal specialist when the
vitrectomy was done that the surgery eye would eventually develop a cataract.
This is because while the laser used for the retinal repair was focused at the
back of the eye, putting all that energy through the lens tissue is akin to
inserting a hot wire through an egg white, so it causes a localized opacity.
This was not a matter of "if" I would get a cataract in that eye, but
rather of how soon it would become objectionable.
Within 6 months the focal distance in my right eye
shortened to about half of normal and distance vision in that eye deteriorated
to 20/200. I could no longer adjust a scope to have the reticle sharp, and
using the sights on a revolver became impossible. All I could do was impose a
fuzzy gun over a fuzzy silhouette and instinctively point-shoot Applegate
style. I got some extensive coaching from a retired FBI academy instructor and
have since become a believer in point shooting, but that is another story...
For those who want more on this read Applegate's book Bullseye's Don't Shoot
back and follow it. It works.
While I could have gotten new corrective lenses and
lived with my condition for a while longer, my doctor advised that the younger
I was when I had the surgery the better the chance for a successful outcome,
because the eye then is then more flexible and resilient that it would be if I
waited a year or so longer. I would enjoy more years of good vision by having
the surgery sooner, rather than later. Being active and still working full time
working outdoors I decided not to wait on the surgery. I had it done and my
outcome has been wonderful. My intraocular lens is an AcrySoft
Natural by Alcon Laboratories which is light blue in color with UV filter.
I can function fine without glasses, although due to the nature of my outdoor
work I wear progressive Transitions lenses most of the time. My vision so
equipped is like being 20-years old again.
