Endothelial Cell Loss After Artisan: To Explant or Not to Explant?
Mahjoub Salah (1)
1. Clinique Ophtalmologie Tunis
We will report a case of endothelial loss (cell count below 2000 cells/mm2) 3
years following an uneventful Artisan phakic IOL implantation. The fellow non
implanted eye was diagnosed with cornea guttata. Therapeutic options will be
discussed including IOL retention or explantaton. Long-term outcome (7 years)
will be reported.

Challenging Endothelial Examinations in Refractive Surgery: The
Role of the Reliability Index
Cesar Abib Fernando (1)
1. Federal University of Parana
Endothelial diseases, endothelial stress and low endothelial cell density are
frequently examined wrongly by specular microscope (SM) limitations and
sample errors existing in the examination process. Risk situations appear
where the type of SM wasn›t chosen correctly and where endothelial
examination wasn›t performed correctly. Here, the role of reliability index to
SM is presented. Choosing the right type of SM, contact or non-contact, and
knowing the reliability index of the specular microscopy, can avoid endothelial
complications on refractive surgery.

Refractive Surgery in Keratoconus

Keratoconus has been traditionally considered a contraindication of refractive
surgery. However, recent evidence confirms the applications of corneal
wavefront guided correction of limited amounts of metropia and its combined
use with collagen crosslinking, improving quality of vision in the keratoconic
patient. Intraocular lenses, especially toric designs, are a great added value in
the correction of the ametropia related to stable keratoconus. The algorithm for
the different indications of refractive surgery in keratoconus will be highlighted
during this presentation.

Reversing Refractive Complications: Back to 20/20
Gulani Arun (1)
1. Gulani Vision Institute
Purpose: To present an innovative conceptual and surgical protocol for
correcting refractive complications aiming for unaided emmetropia.
Methods: Patients with all kinds of refractive surgery complications including
Lasik laser, Kerato-refractive and premium IOLs underwent a corrective
surgical plan which may include Laser ASA, Laser Corneoplastique and or
Laser -Lens based techniques including combinations if required to result in
unaided 20/20 vision.
Results: Outcomes of 20/20 uncorrected vision were possible in these cases
which otherwise would have headed for more interventional surgeries and or
relegated to a life time of poor vision.
Conclusion: Using these elegant and least interventional techniques, refractive
surgery complications can be reversed back to 20/20. These concepts and
innovative applications, including combinations can provide a much needed
relief for cases with complications not only in attempting to help them but
actually aiming for unaided emmetropia.

Treatment for Extreme Hyperopia
Lu Luis W. (1)

WOC2012 Abstract Book
Although an effective treatment method have been available for myopia, the
treatment for hyperopia brings along regression after laser refractive surgery.
Refractive lensectomy came along with predictable results for hyperopic
patients up to about 6 diopters. Unable to wear comfortable contact lenses,
receive laser refractive surgery, or phakic intraocular lenses, extremely short
eyes are left with limited options. We present an effective method of treatment
for these high risk patients willing to overcome their defect.

Differential Diagnosis Between Keratoconus and Pellucid Marginal
Degeneration

Sao Paulo
2. Ziemer Ophthalmic Systems
Keratoconus (KC) and pellucid marginal degeneration (PMD) have common
and differential features producing confusion of diagnosis. As example, there
are cases of each one that resemble the other despite KC seems originated from
a with-the-rule astigmatism and PMD from an against-the-rule astigmatism.
The differential diagnosis between KC and PMD, their clinical history and
their possible evolution will be shown using topography, pachymetry and total
corneal WF data obtained in a series of cases studied with dual Scheimpflug-
Placido combined tomography.
