Information for Professionals
   
  We specialize in prescribing, designing and fitting two types of custom-made GP contact lenses for our patients – Intra-limbal and Scleral lenses.

 
   

The Gas Permeable (GP) contact lens with its smooth, rigid optics creates a new refracting surface on top of the patient’s irregular and asymmetrical cornea thus reducing higher and lower order aberrations and improving vision. Our lenses embody the unparalleled optics of the GP lens with the comfort of a soft lens, making them ideal for therapeutic use. While the lens itself is a superior product, it is the meticulous measurement of corneal irregularities and the accuracy of the design and fit of the lens which is responsible for enhanced comfort and visual correction.

Until now, all scleral GP lenses were fit using trial lenses. The final fit was only as good as the number of trial lenses available, the time available to both patient and practitioner, plus the expertise and skill of the practitioner. Scanning technology is now available to measure the cornea out to the sclera where edge design is critical. Global Refractive Solutions has pioneered in designing one-of-a-kind lenses for the ideal fit on any eye -- surgical or non-surgical.

Scleral lenses are helpful to patients who suffer from the irregular astigmatism that often goes along with corneal transplantation. Those who do not enjoy clear vision with soft lenses due to astigmatism or an irregular cornea, and who cannot tolerate traditional GP lenses would be considered ideal candidates for our mini-scleral design. The lens is also available in a non-translating multi-focal for presbyopes.

Millions of people worldwide suffer from dry eye conditions, often accompanied by severe pain. When all other options have been exhausted, many of them can benefit from the corneal protective effects of a scleral lens. GVH, or graft vs. host disease is one example. Sjogren’s Syndrome is another. Patients who experience reduced wearing time and discomfort from their contact lenses may also benefit from the mini-scleral design.

  Who can benefit?          
 


Nearly any patient with a refractive error is a candidate. Dr. Gemoules has successfully treated patients seeking relief from:

Although many of our patients have come to us post-operatively following LASIK, PRK, RK and LASEK procedures, we have also brought relief and improved vision for increasing numbers of patients who have experienced keratoplasty, high astigmatism, irregular astigmatism, dry eye disorders and corneal scars.

Patients with keratoconus, pellucid marginal degeneration, and other ectasias are also prime candidates for our lenses. These patients are frequently unable to achieve good vision with eyeglasses or soft lenses, and often struggle with discomfort and fluctuating vision of traditional hard or GP lenses.
