Development of the gas-permeable impression-moulded scleral contact lens. A preliminary report.
Although superceded by corneal hard and soft contact lenses for the correction of simple refractive error, the scleral lens still has numerous medical applications in modern ophthalmological practice. However, a major problem with scleral lenses has been the limited wearing time due to corneal occlusion and consequent hypoxia. We present two alternative methods for the production of moulded gas permeable scleral contact lenses.
