Bio-microscopy was believed to be important in 53.7% of optometrists and 48.7% of ophthalmologists. Corneal imaging was important in early diagnosis of KCN 55.8% of optometrists and 57.7% of ophthalmologists. Most of optometrists believed that retinoscopy is most important in KCN diagnosis. Both groups believed that bio-microscopy and corneal imaging are very important in KCN diagnosis. Educational courses should be considered for contact lens fitting, both for optometrists and ophthalmologists. Regular congresses and symposiums may be recommended.
