Nomograms to use with Scleral Profilometry

Reinier Stortelder, BOptom

Scleral lens designs are currently updated rapidly offering more features, more parameters and finally more comfort to the patient. In this poster two guidelines are suggested to make it easier to combine Profilometry for scleral lens designing.

Not Just SAG, a Theoretical Model to Compare the SAG of Soft Lenses

Reinier Stortelder, BOptom; Giancarlo Montani OD, FIACLE, FBCLA; Javier Rojas OD, FAAO, FSLS

Over the last decade the soft lens market has learned that the dropout rate is not improving. The existing method of fitting soft lenses, based on the keratometry values of the eye and BC of the lens does not work.

Considerations when comparing scleral shape differences

Reinier Stortelder, BOptom

Corneal difference maps are a popular method to track and trace the development of corneal diseases as well as the condition of the cornea post operative. Following the same approach for scleral profilometry sounds logical.

HVID Measurements Utilizing Various Instrumentation

Jennifer Harthan OD, FAAO, FSLS; William Skoog; Xiaohua Zhuang, PhD, FAAO; Louise Sclafani OD, FAAO, FSLS

The purpose of this study was to determine HVID measurements provided by different instruments utilized in clinical practice.


Optimizing Soft Lens Fitting: Importance of HVID Versus Corneal Curvature When Choosing a Best Fit Soft Lens

Jason Jedlicka OD, FAAO; Joselyn Dlouhy OD

In an effort to optimize soft contact lens fitting, we sought to determine which is the more valuable data parameter when selecting an initial lens, corneal curvature or corneal diameter, and the significance or impact of each.

Profilometry. The future of scleral lens fitting... Now. #COVIDdriven

Brian Tompkins, BSc (Hons) FCOptm, FBCLA; Reinier Stortelder, BOptom

The advent of COVID-19 has led to many changes around the world including in the field of Optometry. However, new developments arising during this time within both, the scientific and medical fields, have been a silver lining.

A healthy post-graft with a unique scleral lens design

Barry Leonard OD; Reinier Stortelder, BOptom

Fitting scleral lenses on post graft patients is a tricky thing and often a smaller gas permeable lens is preferred to avoid oxygen issues. But obviously, a scleral lens has many things to offer to these eyes which cannot be achieved with GPs.

MicroVault designing utilizing Profilometry

Kyriakos Telamitsi, BSc (Optometry); Reinier Stortelder, BOptom

Profilometry assists designing microvaults precisely and it may help to reduce chair time and refits. Microvaults may offer more comfort to a scleral lens wearer resulting.

Back-Surface Toric Scleral Lens Stabilization as a Fuction of the Amount of Toricity

Javier Rojas OD, FAAO, FSLS; Javier Sebastián OD; Reinier Stortelder, BOptom

The aim was to analyze whether the amount of toricity applied to the back surface of scleral lenses can affect to lens stabilization and rotation.

Designing a scleral lens with two recesses to avoid two pingueculae

Bradley Richlin, OD; Reinier Stortelder, BOptom

For a patient with a high cylinder subjective refraction a scleral lens is one of the best options to restore vision, but a pinguecula might be a contra indication due to discomfort.

Custom scleral lens fitting

Alex Gibberman, OD, FAAO; Troy Miller; Reinier Stortelder, BOptom

Profilometry helps to design custom scleral lenses with a good scleral alignment as well as good centration. Good centration is a critical factor with multifocal scleral lenses.

Ordering a Bi-toric lens based on Profilometry data

Kyriakos Telamitsi, BSc (Optometry); Ilse Flux, MSc Clinical Ophthalmology and Vision Research

Having accurate data on the ocular surface can help us select the right fitting lens. With more designs to choose from, we need more information on the surface to determine what lens design is the best fitting design.

Selecting the best fitting MicroVault based on Profilometry

Ilse Flux, MSc Clinical Ophthalmology and Vision Research; Kyriakos Telamitsi, BSc (Optometry)

Ordering a MicroVault based on height information can assist the practitioner in ordering the best fitting MicroVault. This will likely reduce the number of refits and consequently the total time spent per patient.

Selecting the best fitting hybrid lens based on Profilometry and an automated fitting algorithm

Ilse Flux, MSc Clinical Ophthalmology and Vision Research; Kyriakos Telamitsi, BSc (Optometry); Cian Gildea, BSc (Hons) Optom, FAOI

Predicting the perfect fit based on sagittal height information provided with the ESP can assist in the fitting of fitting hybrid lenses. In combination with an automated algorithm we can reduce the number of refits and speed up the fitting process.

Evaluation of different methods to select the parameters of soft customized contact lenses

Giancarlo Montani DipOptom FIACLE, FBCLA

To improve the choice of the first lens to try or to order empirically it has been suggested that the sagittal height of the anterior segment can be used to calculate the sagittal depth of a soft contact lens with a better result.
