What should be observed in a contact lens patient's eye during an eye examination?

During an eye examination of a contact lens patient, it is essential to observe the entire eye, including the conjunctiva and sclera, in addition to the cornea. The reasons for this comprehensive evaluation are multi-faceted.

Firstly, contact lenses are placed directly on the cornea, and any irregularities or conditions affecting the cornea can significantly impact lens fit and comfort. Therefore, a close examination of the cornea is crucial. However, issues may also arise in the conjunctiva, such as redness or inflammation, which can indicate an adverse reaction to the contact lenses or lens solutions. The sclera should also be examined for any signs of pathology, as conditions affecting this area can influence overall eye health and the well-being of contact lens wearers.

A holistic approach is necessary because contact lens wear can affect not just the cornea but the surrounding structures of the eye as well. Observing all these areas helps in identifying potential complications, ensuring that the lenses are suitable for the patient's eyes, and providing appropriate recommendations or alterations to the contact lens regimen as needed.
