What is the primary purpose of a bandage lens?

The primary purpose of a bandage lens is to provide comfort after surgery. Bandage lenses, typically soft contact lenses, are used postoperatively to protect the surface of the eye, promote healing, and alleviate pain or discomfort. By acting as a protective barrier, they can help reduce abrasion and irritation to an area that may be sensitive after a surgical procedure, such as corneal surgery. Additionally, these lenses can retain moisture, which enhances comfort and support the healing process.

Other options, while relevant in the broader context of contact lenses, do not accurately reflect the specific purpose of a bandage lens. For example, correcting refractive errors is the goal of standard corrective lenses, not bandage lenses. Enhancing visual acuity is important in optometry, but bandage lenses are not designed for that purpose—they prioritize healing and comfort instead. Preventing lens rotation pertains more to stability in specialized lenses, which is not a primary consideration with bandage lenses intended for postoperative use.
