Because the cornea is the eye\u2019s main focusing surface, these shape changes can blur vision and create \u201cirregular\u201d astigmatism. keratoconus is commonly discussed in optometry and ophthalmology clinics when patients have changing prescriptions or distortion that glasses do not fully correct. It is also a key topic in contact lens care, corneal imaging, and corneal surgery planning."}
