Austin Optometry Group

Welcome to Austin Optometry Group, Dr. Annie Ku ( )!

Dr. Ku is a Texas native and highly accomplished optometrist with advanced training in ocular disease, primary care, and brain injury rehabilitation. She is a fellow of the American Academy of Optometry (FAAO) and a Diplomate of the American Board of Optometry - reflecting her commitment to the highest standards of patient care.

She has a special passion for pediatric eye care, neuro-optometric rehabilitation, and helping patients with learning-related vision issues thrive. We’re so excited for our patients to benefit from her expertise and compassionate approach.

With the slow ice melt and for the safety of our valued patients and staff, we have decided to remain closed today, Tuesday, January 27th as well. We anticipate being open usual business hours on Wednesday. Stay safe and warm.

Due to potentially icy roads in the morning, we’ll be opening at 12:00 PM on Tuesday, January 27th

A flashback to last month when so graciously gifted us with these amazing Danish cakes for the holidays. Thank you Tangible Science for taking such great care of us and our contact lens patients!

Scleral Lens Fitting in the Presence of a Pinguecula: From Notching to Vaulting

Design and Theory Differences Between Hyperopic and Myopic Orthokeratology
Myopic orthokeratology (MOK) is widely used, while hyperopic orthokeratology (HOK) is less understood due to limited research. HOK design is essentially the inverse of MOK, targeting opposite corneal changes and refractive corrections. Advanced tools like 2D/3D corneal topography and custom software now help clarify these design differences.

Methods
Custom orthokeratology lenses were created for a myope (-3.00D) and a hyperope (+3.00D). Results were analyzed using:

Software lens curvatures and simulated tear film thickness
Fluorescein lens evaluation
Scheimpflug tomography and 3D Placido-disc topography

Results
Both HOK and MOK lenses achieved 20/20 vision, well-centered treatment zones, and good post-treatment physiological health.

MOK: Forces applied outward toward a single mid-peripheral fluid reservoir compressed the central cornea and thickened the mid-periphery.
HOK: Forces applied inward and outward toward two fluid reservoirs compressed the mid-periphery and thickened the central cornea.
Discussion
HOK thickens and steepens the central cornea to create a convex lens (plus power), while MOK flattens the central cornea for a concave lens (minus power). Though inverse in philosophy, both require precise peripheral lens alignment and centration for success.
HOK forms a central reservoir, shallower than MOK’s mid-peripheral reservoir, and uses a wider return zone to gradually thicken the central cornea. Mid-peripheral compression further emphasizes the convex reshaping.
Both HOK and MOK share similar edge lift designs, ensuring safe fits with adequate lens movement, no punctate staining, and no lens binding. These lenses can be designed using conventional corneal or translimbal orthokeratology techniques.

Success in orthokeratology depends on understanding corneal reshaping forces and lens design. Visualizing changes through fluorescein evaluation and post-wear topography supports optimal results, enabling more patients to benefit from this advanced treatment.

At AOG we’re uniquely fortunate to have access to so many exciting new technologies to measure the anatomy of the eye. Here is a conference case Dr. Wolf presented earlier this year.
