Keratoconus with good unaided visual acuities: two case reports
1Jules Stein Eye Institute, Department of Ophthalmology, UCLA School of Medicine, USA.
Background:
Ophthalmic evaluation of patients with keratoconus (KC) often reveals highly myopic and irregular astigmatic refractive corrections. Irregular corneal astigmatism and central corneal scarring in patients with KC often result in a loss of best-corrected spectacle acuity. Rigid gaspermeable contact lenses generally optimize visual acuities for patients with KC.
Case Reports:
Two cases are discussed of patients who manifested clinically diagnosed KC but unusually good unaided Snellen visual acuities (20/25+ or better) in both eyes.
Conclusion:
Good unaided visual acuities are not necessarily inconsistent with the diagnosis of KC.
