SiH Contact Lens Removal

Silicone Hydrogel Contact Lens Removal

Our 74% Silicone Hydrogel material is highly water retentive and has a more slippery surface than other materials; therefore some patients may benefit from using an alternative removal approach.

For most patients the usual "pinch off" method, as for the removal of normal soft contact lenses, should be used.  Alternatively, the lens can be removed by applying lid pressure from the top and bottom lids in a similar way to that used when removing an RGP lens. An example of the alternative approach to remove SiH lathe-cut contact lenses can be seen below:

 

 

 

 

 

Due to the nature of the material and the high water content, these lenses should be treated as delicate and handled with care to ensure maximum patient satisfaction.

It is the responsibility of the practitioner to assess the patient at the fitting of a new multifocal lens, and to judge whether the patient's visual requirements are being met, ensuring they are still able to acieve the legal standard required for specific tasks.
