Fitting toric contact lenses is very similar to fitting multifocal contact lenses.
• Often, these contact lenses will be a compromise from glasses.
• Set expectations. It makes life so much easier.
• Treat the underlying ocular surface disease problems! If the patient is dry, there will likely be more compromise with torics than in a spherical lens. As the lens dries, it may cause additional lid influence and secondary rotation.
• Consider the influence of material, not just the Rx, when fitting torics. In some cases with small amounts of astigmatism, the patient may be more successful with a better material or modality, even if it only masks the cylinder. The same is true in cases where the cylinder maxes out at 2.75 D. Always consider the material options as much as the Rx parameters in cases where the patient has underlying concerns.
• Daily disposables will typically provide more consistent vision by nearly eliminating the influence of build-up and its impact on lens rotation.
