Rigid Gas Permeable Lenses

From time to time we get requests for quotes on the supply of RGP lenses. These are very specialised contact lenses requiring quite a deal of skill and practice from your eyecare person to prescribe. Wearers of these lenses often have conical corneas (keratoconus) or have required corneal graft surgery. Both conditions can leave the corneal surface irregular and in need of having a rigid contact lens surface to create a "regular" front surface to the eyes' optical system.
In all cases, we advise the wearers of these lenses not to try to cut costs on the necessary optical appliances they must wear. It simply isn't worth it. In many cases, these lenses need fine tuning after the initial fit and there is no satisfactory way of getting this done through a third party retailer. The edge lift of the lens may need increasing or the power may require tweeking for optimum vision and comfort. To those that require these lenses we say "Stay with the practitioner you have come to know and trust regarding these lenses. They are not "off the shelf" lenses and should not be viewed in that way.
Until my next post, have a prosperous New Year and stay safe.
