unlimited tear reservoir capacity
Slide 7
Goals of Scleral Lens Treatment Reduce symptoms and support
healing by restoring a healthy ocular surface environment Improve
blurry vision by masking surface corneal irregularities and
transmitting a sharper image to the retina Prevent damage by
protecting the cornea against the environment and eyelids
Slide 8
Indications for Scleral Lens Treatment Vision Improvement
Correcting the irregular cornea: Keratoconus, ectasia, post-LASIK,
corneal trauma/infections, post corneal transplants (PKP), high
myopia/hyperopia Corneal Protection Exposure keratitis/ocular
surface disease patients Sjgrens Syndrome Persistent Epithelial
Corneal Defects Stevens Johnson Syndrome Graft Versus Host Disease
(GVHD) Ocular Cicatricial Pemphigoid Neurotrophic Corneal Disease
Atopic Keratoconjunctivitis Pharmaceutical Delivery Antibiotic
coverage while a persistant epithelial defect heals Reduce corneal
neovascularization with anti-VEGF medications Pain mediation with
low levels of sodium channel modulators
