KERATOCONUS

LARGER DIAMETER RGP LENSES FOR KERATOCONUS AND CORNEA GRAFTS

Advanced computer programs and digital lathes have facilitated the development of complicated larger diameter RGP lens designs. These lenses have the advantage of improved comfort, better centration and a larger area of vision. These designs are at the forefront of RGP contact lens technology.

MINI SCLERAL LENSES FOR KERATOCONUS AND CORNEA GRAFTS

Mini scleral lenses are manufactured in a RGP material but fit the eye in a unique way. Mini scleral lenses are large and vault the whole cornea and because the lenses rest behind the upper and lower eyelids, the lids do not move across the edges of the lens, providing superior comfort. The lenses totally seal on the sclera and cannot be dislodged, making them ideal for dusty environments and for active people.

MINISCLERAL LENSES FOR CORNEAL GRAFTS

Mini scleral lenses are also manufactured in a rigid gas permeable material but fit the eye in quite a different way.  These lenses are much larger and vault the whole cornea, resting on the white part of the eye.  Mini scleral lenses rest under the upper and lower eyelids and as the lids are not hitting the edges of the lens, the lenses are very comfortable.  The lenses totally seal on the white part of the eye and cannot be dislodged making them ideal for dusty environments and for active sports where conventional RGP lenses may be dislodged.

HYBRID LENSES FOR KERATOCONUS

Hybrid lenses have a hard RGP centre with soft plastic on the periphery.  The transition from the RGP centre to the soft periphery is seamless and provides a smooth surface for the eyelids, giving excellent comfort.  The RGP centre gives excellent vision and the soft periphery gives excellent centration.  The RGP centre vaults the cornea minimising irritation and the soft periphery wraps onto the sclera to ensure stability and prevent irritation from foreign bodies.  Hybrid lenses require a simple peroxide disinfection system.

VISION CORRECTIONS FOR KERATOCONUS AND CORNEA GRAFTS

In early keratoconus and slight distortion of the cornea, spectacles or soft contact lenses are usually prescribed and provide adequate vision. As keratoconus progresses and the corneal irregularity increases, vision quality often reduces. When spectacle or soft contact lens correction no longer provides adequate vision, hard contact lenses can be fitted to imitate a smooth corneal surface that neutralizes up to 90% of the corneal distortion. This substantial reduction in image distortion gives better definition and contrast, reduces ghosting and provides clearer vision.

RIGID GAS PERMEABLE LENSES FOR KERATOCONUS AND CORNEA GRAFTS

Rigid gas permeable (RGP) contact lenses are the most common form of contact lenses used to improve vision for keratoconus. Most patients can wear RGP lenses all day with good comfort, excellent vision, good stability and clear eyes. RGP lenses improve vision the same way for cornea grafts. Placing a smooth rigid surface over the cornea allows the tears to fill in the space between the rigid surface and the corneal irregularity. This provides a reduction in image distortion to give better definition and contrast, reduce ghosting and consequently, provide much clearer vision.

MINISCLERAL LENSES FOR CORNEAL GRAFTS

Mini scleral lenses are also manufactured in a rigid gas permeable material but fit the eye in quite a different way. These lenses are much larger and vault the whole cornea, resting on the white part of the eye. Mini scleral lenses rest under the upper and lower eyelids and as the lids are not hitting the edges of the lens, the lenses are very comfortable. The lenses totally seal on the white part of the eye and cannot be dislodged making them ideal for dusty environments and for active sports where conventional RGP lenses may be dislodged.
