The most efficient technology for measuring central island OrthoK defect

Aaron Wolf, OD, FAAO, FSLS, FIAOMC

Corneo-scleral profilometry may be a superior corneal imaging technology for the detection of subtle focal corneal shape defects from orthokeratology due to its precision of elevation data and the absence of data interpolation in profilometry maps.

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.

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.

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.

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.

Profilometry Precision: A Scleral Lens Fit Utilizing Profilometry

Melanie Mae Patterson, Rebecca Simmons Brown, Samantha Myers (OD , FAAO), Renee Reeder (OD, FAAO , FBCLA , FSLS , FIACLE)

Scleral lenses are a great option for patients with ocular surface disease. A near perfect fit is often required in these patients in order to improve comfort and increase wear time.
