world. This is an initiative to keep our readers well-updated with all the latest news and
happenings in the World of Ophthalmology
It has been our constant endeavour to contribute to the field of Ophthalmology and
now with the launch of this e-journal, we believe we can cater to all your needs once again.
With fresh enthusiasm to dedicate ourselves and to serve you better, we have given
our best in delivering the necessary information on the new technologies and on news
about the forthcoming conferences.
Happy Reading,
Warmest Regards,
P.S.N. Appasamy

“Implantation of Toric IOL involves
a c c u r a t e d i a g n o s i s o f C o r n e a l
Astigmatism, performing accurate
biometry, appropriate IOL calculation,
good surgical technique & verification /
re-correction of axis where necessary.”
Points out Dr. Arulmozhi Varman, a leading Ophthalmologist
from Chennai.
A lot of research and effort has gone into this study...
Dr. Soosan Jacob's research abstract
on her Paper titled “Contact lens
assisted collagen cross linking (CACXL):
A new technique for cross linking thin
Corneas”.
Treating the Keratocone is the topic
that is making the rounds and with FDA approvals in the
pipeline for a few other techniques, this will definitely prove to
be one ground breaking research

Appasamy Associates has always been lucky to find the best talents and this indeed has
proved to be one of our best strengths. We are humbled by such personalities who, year after
year, strive hard for the growth of this organisation.
Mr. S. Gurumoothy, our zone manager for the states of Andhra Pradesh and Karnataka, is
one such pillar and we are proud to say that he has been a part of our organisation since the early
80s. His dedication is heart-warming and we dedicate this as a token of our appreciation.
Mr. S. Gurumoorthy can be contacted at [email protected]
My new technique called Contact lens Assisted Cross-1linking, or CACXL , for cross-linking thin Corneas acts by
artificially increasing the thickness of the ultraviolet (UV)
absorption medium anterior to the endothelium by using a
riboflavin-soaked contact lens and a pre-contact lens riboflavin
film.
With this technique, cross-linking can be performed on a
greater number of Patients and also on Patients with thinner
Corneas than those who undergo conventional Corneal cross-
linking. CACXL is not dependent on the swelling properties of
the Cornea, as in hypo-osmolar cross-linking and produces a
more stable riboflavin film.
A daily disposable Bausch + Lomb SofLens made of
hilafilcon B is soaked in riboflavin 0.1% solution for 30 minutes,
while the same solution of riboflavin is also applied to the
Cornea every 3 minutes for the same period of time.
The riboflavin-soaked contact lens is then applied to the eye
and A pre-contact lens riboflavin film is also applied over the
contact lens.
The technique has shown very good anatomic and visual results in early reported cases. The type of lens used should be thin and
must not have a built-in UV barrier or it will negate the effect. Contact lens assisted CXL is thus a new technique for cross-linking in
Corneas less than 400 µm thick.

1. Pre-operative Evaluation
2. Surgical Technique
3. Post-op Verification and Readjustment
Pre-existing Corneal astigmatism is the most common cause for residual astigmatism. After modern cataract surgery, incision size
has come down steadily. Design of IOL and placement of incisions have played a major role in bringing down surgically induced
astigmatism (SIA). Temporal incisions of size 2.2 mm or less can for all practical purposes be taken as astigmatically neutral. Incision
placed closer to vertical axis will induce a predictable degree of astigmatism. This factor can be used to our advantage to nullify pre-
existing astigmatism by placing incisions specific to our requirements.
Pre-existing astigmatism of above 1D (some prefer 1.5D) are ideally suited to be addressed by Toric IOL implantation. Toric IOLs come
in two designs: single piece haptic and plate haptic. Lens material used is either hydrophobic or hydrophilic with hydrophobic coating for
better adherence to posterior capsule. The laser marks indicating the axis of cylinder in the Intraocularlens is etched at the optic –haptic
junction in lenses with loop haptics and along the long axis in plate haptic lenses. Toric lenses have to be placed in the desired axis in the
eye. The muscular shaped loop design of Supraphob preloaded hydrophobic Toric lens from Appasamy Associates has better strength
to retain the lens in its designated axis in the long run too.
Supraphob Toric comes in the following powers:

Introduction
TORIC IOLs IN OPHTHALMIC PRACTICE
Cataract surgery has made several leaps with the introduction of intraocular lenses. What once began as a means to avoid aphakic
glasses and its inherent side effects of magnification has now gained enormous potential in the recent past. This new generation IOL is a
technogical marvel giving a whole new meaning to emmetropia.
Monofocal lenses provided patients independence from glasses. The next obvious development would be to achieve the same for
near vision. This gave rise to Multifocal IOLs. Surprisingly, treating astigmatism using IOL is not very widespread considering the fact that
a sizable population does suffer from this refractive error. Available data indicates that approximately 70% of the general cataract
population has at least 1.00 D of astigmatism. This indicates that the best of monofocal lenses, surgical methods or calculation cannot
achieve emmetropia. I mplantation of Toric IOL will involve accurate diagnosis of corneal astigmatism, performing accurate biometry,
appropriate IOL calculation, good surgical technique, verification & re-correction of axis where necessary. These points will be illustrated
under following headings.

SMILE SPACE
I overheard two EMT volunteers talking about the time they went to the aid of
an elderly man. As one took down his information, the other opened his shirt
to attach EKG cables.
"Any history of heart trouble?" asked the first volunteer.
"None," said the patient.
Looking at the telltale scars of bypass surgery, the second
volunteer wasn't so sure. "In that case," he said, "do
you remember when the lion attacked you?"
My mother has tried her hand at several careers, some even concurrently.
Imagine the surprise of both a hospital patient and
my mom when the patient woke up after surgery and,
upon seeing who her nurse's aide was, yelled,
"What are you doing? You're the woman
who helped me pick out interior paint colors!
Dr. Keiki Mehta, is a leading ophthalmic surgeon in India, a prolific teacher and a pioneer in cataract and
refractive surgery in the country.
In addition to his clinical practice, Dr. Mehta conducts free eye camps nationwide, is Chairman of the Low
Vision Centre at Maharashtra, and runs a 25-bed free eye hospital in a rural area of Karjat. Dr. Mehta is
currently Medical Director and Chief of Surgery for the Mehta International Eye Institute and Colaba Eye
Hospital, which he founded and which is now considered to be Asia's most advanced Ophthalmic institute.
He also holds a professorship at the D. Y. Patil Medical College and Hospital in Mumbai and serves as
Chairman and Organizing secretary of the Eye Advance Congresses.
Over the course of his long and distinguished career, Dr. Mehta performed the first intraocular implant
and the first LASIK procedure in India and has earned a reputation as the "Father of Indian
Phacoemulsification" for his efforts in that field.
Dr. Mehta's numerous awards include the American Implant Society's prestigious Appreciation Award for creation of the first soft
intraocular lens implant and the National Eye Research Foundation's Grand Honors Award for Ophthalmology research, the only Indian
ever to receive the award. He was also awarded the very prestigious "Padma Shree Award" from the hands of the President of India in
2008 for outstanding services to the cause of Ophthalmology in India.
Dr. Mehta will also be this year's Honored guest at ASCRS-ASOA Annual Symposium and Congress that is to be held in Boston later this
month. He will receive the Honored Guest award along with Dr.PhilipHessburg, of Minnesota.
