Purpose: Due to their purely scleral contact zone non-ventilated scleral contact lenses (SCL) can be used to correct even extreme keratectasia, even if corneal contact lens fitting failed. As the space between the SCL and the cornea is filled with tears or physiological sodium chloride solution, they also can be used for patients with severe aqueous deficient dry eyes. The use of PMMA for scleral lenses limited wearing to 4 hours a day. Despite the fact that modern rigid gas permeable scleral lenses made of siliconacrylate fluorocarbon copolymer with a DK of 115 allow a daily wear of up to 10 hours they are rarely used in Germany. Here we present our experiences with scleral lenses in patients with corneal ectasia or severe aqueous tear deficiency.
Method: We attempted to fit 25 eyes (16 patients) to treat corneal ectasia or ocular surface disease with scleral lenses, if corneal lenses (e.g. piggy back lens system, keratokonus lens) had been unsuccessful. The indications included keratokonus (n=4), keratoglobus (n=3), pellucide marginal degeneration, postkeratoplasty astigmatism (n=4), severe keratokonjunctivitis sicca (n=9), exposure keratopathy (n=1) and severe irregular astigmatism (n=1).Keratometry and visual acuity before and
