I
have always liked the start of the New Year. While
we are more than just a "few days" into 2003, I have
had a chance to reflect on things, both personal and
professional and decide what I would like to accomplish
in the coming months. The process of self analysis
and introspection can get a little exhausting, but
often there is good that comes from it. From this
activity, I usually come up with some type of game
plan on where I would like to focus my energies and
the kind of work that I want to be involved with.
Indeed,
one of the areas that I am particularly excited about
is the further development of new technologies and
what they might mean for doctors and their patients.
Newer designs in contact lens design and manufacture
are being explored NOW with some of these seeing the
light of day by June of this year. Newer diagnostic
machines will be deployed in medical and surgical
clinics which will better allow doctors to diagnose
visual ailments and help to design treatment protocols.
More and more doctors and patients are finding Surgical
Eyes and its renewed message of hope as we all strive
to promote visual wellness. Much should happen this
year in 2003.
Sincerely,
Gregg Eric Russell, OD, FAAO

Miss
W presented with problems driving. Vision was poor at night, but passable
through the day, although she was aware that it was not as good as
it could be. She had had RK 12 years previously and reported good
vision until recently. She wore no glasses or contact lenses, and
had not had any correction since her RK surgery. Her last eye test
was 11 years previously. Miss W was 35 years old and worked as a teacher's
aid. Internal and external examinations were unremarkable. Miss W
had 16 incision RK R&L extending to 1mm from the corneal centre. The
RK incisions looked "wide" with reasonable scar tissue in the incision.
There was no surface damage or staining with fluorescein and tear
break-up time was 12 seconds R&L.
Post
Op RK patient showing 8 radial incisions with moderate scarring. This
picture is NOT from the case being presented, but is shown for consideration.
Unaided vision was 6/60 RE and 6/36 LE. Miss W corrected to: RE: +7.25/-3.75x
120 6/24 KE: +5.50/-4.75 x 95 6/15 Topography showed significant corneal
distortion in the peripheral zone as well as in the central 2mm optical
zone. Trial contacts were fitted using VMC design lenses from Gelflex
laboratories. These lenses had an optical zone of 6mm. Being a reverse
geometry design, these lenses were chosen to align the lens geometry
as close to the cornea as possible. Several lenses were trialed before
fittings of: RE: 9.20 / 11.2 / +2.25 LE: 9.05 / 11.2 / +1.50 VMC design,
Boston XO material, Blue tint. The lenses were judged to fit well
and were ordered from Gelflex. They arrived 3 days later and Miss
W arrived for her fitting. Vision was 6/6 RE and 6/7.5 LE. Fit was
judged to be good using fluorescein and a slit lamp with cobalt filter.
Miss
W returned for review 1 week later. She reported increased use of
the lenses and good vision. She reported that her vision had not been
as clear since before her RK surgery. Comfort was still an issue but
the lenses were being worn up to 10 hours per day. The next aftercare
visit was 2 weeks later. Comfort was still an issue, but the lenses
were being worn 12 hours per day and vision was excellent. The lenses
fitted well and no staining or other anomaly was present under slit
lamp examination. Miss W returned 8 weeks later, having missed several
appointments. She was wearing the lenses 6-10 hours per day but was
still aware of the edges. The lenses were returned for adjustment
and were refitted 2 days later.
Miss
W was much happier and was asked to return in 2 weeks for review of
her lenses. At this review, Miss W complained that the lenses were
still causing discomfort and that wearing time was down to 4 hours
per day, 3-4 days per week. Having worn the lenses for 3 months, it
was decided to try soft toric lenses. New lenses were ordered from
Gelflex, with parameters of: 8.7 / 14.5 / +7.75 / -4.00 x 120 8.7
/ 14.5 / +5.75 / -5.00 x 95 40% material, blue handling tint The lenses
were ordered with an increase in centre thickness of 0.06mm to compensate
for corneal distortion, but to keep as thin as possible to retain
oxygen transmissibility. On collection, Miss W had acuity of 6/9=
RE and 6/12+ LE. The lenses fitted well and gave adequate movement.
Miss W returned for aftercare 2 weeks later. She reported wearing
time of 14 hours per day, 7 days per week. She noted that vision was
not as good as with the hard lenses, but comfort was excellent and
there was no awareness of the lenses over the full days wear. Miss
W returned for an aftercare 2 months later and reported all being
well and wearing time as 14-16 hours per day, 7 days per week. She
was now confident with driving and was not willing to go out without
her lenses. Vision and fit remained the same, and no staining was
recorded.
DISCUSSION
While excellent vision was made with reverse geometry Gas Permeable
lenses, comfort could still not be made sufficient to wear on a full
time basis. While visual acuity was significantly less with soft toric
lenses, but wearing time was increased to as much as the patient chose.
As much as the fitting and vision were excellent with the GP lenses,
comfort remained an issue after 3 months. The soft toric lenses were
able to get Miss W below the legal driving standard and with enough
clarity to wear on a fill time basis.

of contact lenses. Brien
Holden, PhD, DSc, OAM, Serina Stretton, PhD, Kylie Evans, BA, and
Deborah Sweeney, BOptom, PhD. Contact Lens Spectrum. January 2003.
From the article: "Currently there is much hype about using custom
ablations to reduce the horrendous aberrations resulting from spherical
LASIK. Making aberration-free or aberration-controlled contact lenses
is far less difficult. The future will know no other type of contact
lens." More

In
this study, Researchers determined that nerve fiber bundles decreases
by 90% immediately after LASIK and while subbasal nerve fiber bundles
gradually return, their number remains less than half of that before
LASIK at the one year mark.

The
Role of Ray Tracing Technology. David
R. Hardten, M.D.Ophthalmology Management.
February 2002.
From the article: "Our visual system, though, has forward aberrations,
that is, a light source from outside of the eye is focused by the
visual system and imaged on the retina. Ray tracing, or LASEREFRACTION,
technology from the Tracey Visual Function Analyzer (Tracey-VFA) measures
forward aberrations by determining the retinal location of a light
ray projected into the eye. With Hartmann-Shack devices, the lenslet
array measures all points within the pupil simultaneously and is therefore
susceptible to data confusion by highly aberrated eyes. The Tracey-VFA's
LASEREFRACTION measures each point of light sequentially, minimizing
confusion from the crossing of data points." More

Dr. Dan Reinstein, MD MA(Cantab) DABO FRCSC
Dr.
Reinstein combines extensive post-doctorate fellowship sub-specialty
training in refractive surgery, ophthalmic ultrasound, and ultrasound
bioengineering as well as his experience as a research scientist in
his field. His special interests include the systematization of surgical
technique and the assessment and correction of the complications
of refractive surgery. See Case
Histories.
In scientific
research, Dr. Reinstein initiated and has led the development and
use of a new 3D VHF digital ultrasound scanner that for the first
time can provide thickness measurement of individual corneal layers
as well as the anterior segment ocular dimensions with micronic precision.
He has pioneered the use of this technology, with a focus on the study
of the healing responses within the cornea and analysis of the complications
of corneal refractive and intraocular lens implant surgery. This technology
has received FDA approval for the commercial version: Artemis™ and
is now available through Ultralink, LLC (www.arcscan.com)
Because the Artemis can determine the exact anatomical basis for
surface corneal irregularities, it provides information for the analysis
of the optical complications of refractive surgery that cannot be
obtained by any other means. Anatomical
analysis of the cornea can provide answers as to the cause of irregular
topography, thus bringing the field of corneal refractive surgery
to a new level. Instead of relying only on the outside shape of the
cornea, surgeons are now capable of separating epithelial from flap
or mechanical changes producing unwanted irregular topography. The
understanding of epithelial thickness profiles, stromal surface shape,
and residual stromal bed measurements is proving vital to the ability
to not only avoid complications, but to enable their accurate diagnosis
and correction. Another
unique capability of the Artemis™ is it's ability to measure angle-to-angle
and sulcus-to-sulcus dimensions within the eye directly. This promises
to greatly improve the safety on phakic intra-ocular lenses, which
are currently under FDA review, but lacking final approval. For
a list of publications on the Artemis technology, see: www.reinsteininstitute.com.
Dr. Reinstein
is in private practice in London, UK as medical director of the London
Vision Clinic in the Harley Street district.
Family
- lives in central London with his veterinarian wife Ursula and
their two children Julia and Maxwell.
Hobbies
- Concurrently with his medical career Dr. Reinstein has been playing
the saxophone for 25 years including two years of study on a performance
scholarship at the Berklee College of Music, and he continues to play
jazz on a regular basis.
