'Refitting current toric patients from hydrogels into silicone hydrogel torics is a great opportunity to cement your relationship with your patient ' states Patricia M. Keech in Review of Cornea & Contact Lenses. Early presbyopic patients in spherical lenses who have small amounts of residual astigmatism present a significant pool of potential according to the author. The article considers the question: 'One material does not fit all, so how do we choose the best option for each patient?'

Researchers from Turkey looked at astigmatic neutralization with toric and spherical soft contact lenses. Spherical lenses failed to mask corneal toricity during topography, according to the study, while toric lenses caused central neutralization and a decrease in corneal cylinder in low and moderate astigmatic eyes.

Neil Pence also discusses this topic in a recent column in Contact Lens Spectrum, in which he describes a patient with a prescription of OD -16.50 -4.75 x 180 and OS -14.50 -3.00 x 180, and he poses the question that is the title of the article: 'Can I Get That in a Silicone Hydrogel?' His 'Contact Lens Design & Materials' column looks at the current custom silicone hydrogel options available.

Here's an example in which soft specialty lens technology had life changing consequences. This case presents a young medical student who was so limited by poor vision that she had special dispensation to have her notes printed out in large print format. I fitted her with a pair of specialty soft lenses for keratoconus, with remarkable improvement refractively. This lens also has a special feature in which 'sectors' of the lens can be ordered with different degrees of flattening or steepening and specified in degrees that define where these asymmetric peripheries are applied.

In the last edition, we discussed the effect that horizontal visible iris diameter (HVID) has on the sagittal height of the cornea. Since most "off the rack" soft contact lenses are available with only one diameter and either one or two base curves, we want to share with you the effect that corneal diameter has on soft contact lens fitting in our day-to-day contact lens patients.
