A Comparison of Central Island Orthokeratology Defect Between Placido Disc Topography, Scheimpflug Tomography, and Fourier Projection Corneoscleral Profilometry

Aaron Wolf, OD, FAAO, FSLS, FIAOMC

This comparative study demonstrates that Fourier projection corneoscleral profilometry may be superior to Placido-disc topography and Scheimpflug tomography for detecting subtle orthokeratology central island defects due to its precision and lack of data interpolation.

Scientific Poster by Sheila Morrison, Alia Cappellani and Andrea Lasby on managing post-refractive myopia with dual base curve soft lens.

Two curves are better than one: Management of post-refractive myopia

Sheila Morrison, OD, MSc, FAAO, FSLS, Alia Cappellani, OD, FAAO, FSLS, Dipl. ABO; Vanessa Lin, OD; Andrea Lasby, OD, FAAO, FSLS

This novel custom soft, oblate, dual base curve lens design was effective for several post-refractive contact lens fittings. Further study will be needed to elucidate impact of other lens fitting parameters used in conjunction with custom-soft dual base curve designs.

OC-SAG Values in 360 Degrees

Javier Rojas, Eef van der Worp, David Piñero

When looking at the anterior ocular surface in a 360-fashion – this study found that there are marked differences in OC-SAG values in different meridians.

Elevating to the next level: A case series of dual sag scleral lens

Alia Cappellani, OD, FAAO, FSLS, Dipl. ABO; Sheila Morrison, OD, MS, FAAO, FSLS; Andrea Lasby, OD, FAAO, FSLS; Vanessa Lin, OD

Digital design is the way of the present and future, though currently trial lens fitting with dual sagittal height designs is relevant and useful in clinical practice and often necessary for power.

Scientific poster on the importance of peripheral corneal data

Peripheral corneal data is highly relevant

Dr Rolando Ortiz, OD; Reinier Stortelder, BOptom ; Karin Brown Balvert, FBDO CL

Using real elevation data of the peripheral cornea can reduce the number of refits for the Paragon CRT orthokeratology lens and the chair time. This study could be repeated with larger sample sizes and involving multiple fitters to minimize fitter bias.

Precise Empirical Scleral contact lens fitting designing utilizing Profilometry

Kyriakos Telamitsi, BSc (Optics), Optometry, Contact Lenses Practitioner, FSLS, ISCLS

Thanks to the accurate scleral data Profilometry assists designing empirical freeform scleral contact lenses fitting precisely and it may help to reduce chair time and refits, leading to happy patients.

Scientific poster on visual rehabilitation using scleral lenses on a patient with corneal scarring and pinguecula

Visual Rehabilitation with scleral lens in a patient with corneal scarring and pinguecula

Karin Brown Balvert, FBDO CL, MBCLA; Joana Marta, Orthoptist, Contact Lens Specialist

With larger diameter scleral lenses, pingueculas can be hard to fit, but with the improving technology in the labs, and accurate measurements of the scleral surface, it was possible to get a good fitting lens.
